(First Embodiment)

&Quot; Overview of content providing system "

1 is a diagram for explaining a configuration of a content providing system according to a first embodiment of the present invention. The content providing system includes sub-contents (second contents data; web advertisement) 121 related to contents of each scene of main contents (first contents data; television program) 101, (22). In the present embodiment, for example, when a television program displays a scene of drinking a beer or other beverage, a web advertisement of a beer company, a beer restaurant, or the like is displayed on the terminal device 22 in response to the display. A content providing service for providing a web advertisement in a push-type form linked to this television program is hereinafter referred to as a " link advertisement providing service ". The television program as the main content 101 is broadcast from the broadcast station 1 and the television receiver 21 receives the television program and plays it back toward the viewer 20. [ In the present embodiment, the television program refers to the entire content broadcasted from the broadcasting station 1, and includes not only a so-called television program main body but also a television commercial (television CM). When the viewer 20 is in possession of the terminal device 22 and the viewer 20 watches the television program, the terminal device 22 is also located in the vicinity of the television receiver 21 (which is soundproofed from the television receiver 21) The distance to which a voice can be received).

1, the broadcasting station 1 has a transmitting device 10, and the transmitting device 10 modulates the main content 101 and transmits (broadcasts) in the frequency band of the terrestrial digital channel of the UHF band. In addition, the broadcast station 1 has a link information selection superimposing portion 11. The link information selection superimposing unit 11 analyzes the contents of various data signals (various kinds of signals such as audio signals and image signals) constituting the main contents 101 and supplies the sub contents (The advertisement) 121 to the signal of the main content 101. In this case, The link information selection superimposing unit 11 corresponds to the content editing apparatus of the present invention.

Although various methods can be applied to the overlapping of the information ID 103 with the main content 101, in this embodiment, the method disclosed in the international patent application (International Publication No. 2010/016589 pamphlet) by the applicant is applied do. This method converts the information ID 103 into an acoustic ID 104 which is an acoustic signal of a specific frequency band by spread spectrum and frequency shift and superimposes the converted acoustic ID 104 on the audio signal of the main content 101 .

Fig. 2 shows the relationship between the frequency band of the audio signal included in the main content 101 and the frequency band of the sound ID 104. Fig. As shown in Fig. 2, the upper limit frequency of the audio signal used in the television program, which is the main content in the present embodiment, is about 16 kHz. On the other hand, the upper limit frequency of the audio signals that can be transmitted / received and reproduced by the transmitter 10 and the television receiver 21 is about 20 kHz. Since the sound ID 104 is a sound signal in the frequency band of 18 to 20 kHz, the sound ID 104 is more than the frequency band of the normal sound signal included in the main content 101 (television program) 10 and the television receiver 21 are superimposed on the frequency bands in which transmission / reception and reproduction are possible. When the audio signal of the main content 101 and the sound including the sound ID 104 are sounded from the speaker of the television receiver 21, the sound ID 104 can be easily separated from the audio signal of the main content 101 Do. Details of this method will be described later.

The terminal device 22 held by the viewer 20 receives the sound signal of the main content 101 soundproofed from the speaker of the television receiver 21 and the sound including the sound ID 104. [ The terminal device 22 demodulates the sound ID 104 included in the sound that has been picked up into the information ID 103. [ The terminal device 22 accesses the ID resolution server 41 of the management center 4 and accesses the URL 141 of the sub-content 121 corresponding to the information ID 103 obtained by the demodulation Address information indicating a storage location). The terminal device 22 acquires the information ID 103 composed of a short code (for example, a four-digit number) from the television receiver 21 as the sound ID 104, It is possible to obtain the URL 141 composed of a long code (a predetermined character string such as an alphanumeric character) based on the URL 141. [ The terminal device 22 accesses the sub-contents providing server 31 on the basis of the acquired URL 141 to acquire the sub-contents 121 and displays the sub-contents 121 on a display provided in the terminal device 22. [

In the ID resolution server 41, an information ID 103 is stored in association with the URL 141 of the sub-content 121. The ID resolution server 41 provides the URL 141 corresponding to the requested information ID 103 in accordance with the access from the terminal device 22. [ The ID resolution server 41 converts the information ID 103 received from the portable terminal apparatus 22 into the URL 141 corresponding to the information ID 103 and transmits the converted URL 141 to the portable terminal apparatus 22 is referred to as " resolution of the information ID ".

The sub-content providing server 31 is a web server that stores the sub-content 121 indicated by the URL 141 so as to be able to provide the sub-content 121 121). ≪ / RTI >

The above-described series of processing of the terminal device 22 (demodulation of soundproofed sound from the speaker of the television receiver 21, demodulation of the sound ID 104, acquisition of the URL 141, access to the sub- (Display of the sub-contents 121) are automatically performed by the sub-contents acquisition program executed in the terminal device 22. [ Therefore, for the viewer 20 having the terminal device 22, the sub-content 121 (web advertisement) linked to the main content (television broadcast) 101 is provided in a push-type form.

It is assumed that the advertiser 30 of the web advertisement as the sub-content 121 arranges the created sub-content 121 in a state in which the sub-content providing server 31 can distribute it. The sub-contents providing server 31 may be a general web server.

Hereinafter, the content providing system will be described in detail.

The " link information selection overlapping unit 11 "

The link information selection superimposing section 11 has a content analyzing section 12, an information selecting section 13, an entry database 14, an acoustic ID converting section 15 and an audio synthesizing section 16.

The content analyzing unit 12 analyzes the content of the inputted main content 101 and generates and outputs the keyword 102. [ The main content 101 is analyzed by, for example, analyzing the main content 101 by image analysis or voice recognition. Here, image analysis refers to a technique of extracting features such as outline and color tone from an image and recognizing what object is being reflected. Speech recognition refers to a technique of recognizing information included in speech based on characteristics such as a waveform of a speech signal and a frequency structure. These techniques are well known in the art, and detailed description thereof will be omitted. The content analyzing unit 12 judges which scene of the main content 101 the scene of the main content 101 is based on the result of the image analysis and the speech recognition performed on the inputted main content 101 and displays text information Is generated and output. That is, the keyword 102 is a language representing the content of the main content 101 or a language representing the characteristics or attributes of each scene of the main content 101. [ The keyword 102 is input to the information selection unit 13. [ As the text information, information that indirectly represents the contents of the scene, for example, ID information or metadata, may be used instead of the keyword 102 directly representing the contents of the scene.

The content analyzing unit 12 inputs the main content 101 broadcasted from the broadcasting station 1 in real time and sequentially generates and outputs the keyword 102. [

The generation timing of the keyword 102, and the generation interval can be appropriately determined. For example, it is also possible to detect that the scene of the main content 101 has been changed by the content analyzing unit 12 at every predetermined time interval (for example, every 5 minutes), and detect the timing of the detection.

The information selecting unit 13 searches the entry database 14 using the keyword 102 input from the content analyzing unit 12 and searches for the keywords And selects the information ID 103 corresponding to the sub-content 121 that is suitable for the content 102. [ The information selecting unit 13 outputs the selected information ID 103 to the sound ID converting unit 15 and sends the selection result to the management server 40 of the management center 4 as the entry selection information 105 do. Here, the entry of the sub-content 121 means that the sub-content 121 (or the corresponding information ID 103) is associated with the specific keyword 102 and registered in the entry database 14 in advance. In the entry of the sub-content 121, the entry information 122 is transmitted from the advertiser 30 to the management center 4. The entry information 122 includes at least a keyword 102 and an upper limit unit price. The entry information 122 may further include various kinds of information. In this embodiment, it further includes a budget, a client name, a product name or a service name, a business type code, and a variety code or a service code. The entry of the sub-content 121 will be described later.

The configuration of the entry database 14 will be described with reference to Fig. The information entry database 14 stores information such as the keyword 102, the upper limit unit price and the budget included in the entry information 122, the URL 141 corresponding to the entry information 122, and the information ID 103 Have a table to remember. Essential information as the entry database 14 of the present invention is information defining a correspondence relationship between the keyword 102 and the information ID 103. [ In this embodiment, the keyword 102, the information ID 103, and the upper limit unit price are essential information registered in the entry database 14, and other information (budget, client name, product name or service name, Code, URL, etc.) can be appropriately added or omitted in accordance with a selection rule to be described later.

The entry database 14 groups and manages entries of a plurality of sub-contents 121 for each keyword 102. Each entry belongs to a group of keywords 102 included in the entry information 122. [ However, when the entry information 122 includes a plurality of keywords 102, the entry information 122 belongs to each group of the plurality of keywords 102.

The upper limit unit price (yen / access) is set to 1 (1), which is charged from the management center 4 to the advertiser 30 according to the number of times the subcontent 121 is viewed (accessed) by the viewer 20 (or the terminal device 22) It is the upper limit of the unit price per access. When the keyword 102 is input from the content analyzing unit 12 to the information selecting unit 13, the information selecting unit 13 selects the entry information 122, and performs automatic bid processing based on the upper limit unit price. Here, the automatic bidding process is a process in which an AI (artificial intelligence) is set for each entry, and a successful bidder is determined by bidding by the AI. The AI calculates a suitable price for the keyword 102 based on information such as the upper limit unit price and the budget included in the entry information 122 in charge of the AI, and bids.

The information selecting unit 13 selects one sub-content 121 from the sub-content 121 grouped for the keyword 102 based on the result of the automatic bidding process. When there are a plurality of entries in the same keyword, the sub-contents 121 having the highest upper-end unit price are selected, but the information selecting unit 13 selects the sub-contents 121 from the entry The selection of the sub-content 121 is adjusted and adjusted by changing the weight of the excluded or comparison of the bid price.

The information selecting unit 13 may be configured to adjust and appropriately select the sub-contents 121 based on various information such as a client name, a product name or a service name, a business type code and a variety code or a service code included in the entry information 122 . In addition, the industry code can use codes of the Japanese standard industrial classification. For example, the classification code of JIS (Japan Industrial Standard) or JAS (Japanese Agriculture & Forestry Standard) can be used as the variety code.

As the selection rule, for example, the following may be used.

"Clients who compete with sponsors of television programs do not choose."

"We do not choose ads of the same type of industry or the same variety of products as those advertised in television programs."

"We prefer to choose web ads for large clients and high corporate clients."

&Quot; Select the sub-content 121 with a high priority. &Quot;

"I do not choose ads in programs where advertising is prohibited (eg, news programs) or scenes."

The selection rule is not limited to the above. The sponsor company of the program or the advertisement prohibition information may be included in the main content 101 as meta data or may be provided by broadcast program information such as EPG. In this case, the content analyzer 12 may extract metadata from the main content 101 and extract necessary information from broadcast program information such as EPG. In addition, according to the result of evaluating the extent of the CSR of the client company as the advertiser 30, the degree of load on the environment of the advertisement or the degree of fair trade of the advertisement, May be applied. These evaluations may be performed by the administrator of the management center 4 and the rules created by this evaluation may be provided to the link information selection superimposing unit 11. [

The sound ID conversion unit 15 subjects the information ID 103 inputted from the advertisement selection unit 13 to spectrum spreading and converts it into an acoustic ID 104 as a sound signal. The method of converting to the sound ID 104 uses the method disclosed in the above-mentioned International Publication No. 2010/016589 pamphlet.

4 is a diagram showing an example of the configuration of the sound ID conversion unit 15. In Fig. The spreading code generation unit 201 generates a spreading code (PN) for spreading the frequency spectrum of the information ID 103. As the spreading code, a pseudo-random number code string having a constant circulation period such as M series is used. The information ID 103 is periodically adjusted so that one symbol period coincides with one cyclic period of the spreading code.

The multiplier 202 multiplies the information ID 103 by the spreading code. This process is a process called spectrum spreading. By this processing, the spreading code is phase-modulated by the value of the information ID 103 (numerical value of 1 or 0) every cycle, and the frequency spectrum of the information ID 103 is spread.

The information ID 103 whose frequency spectrum is spread by the multiplier 202 is converted into a differential code by the differential encoding unit 203. The differential encoding process is a process for replacing the value of each chip of the spreading code with the value representing the change from the preceding chip from its absolute value. With this differential encoding, it is possible to demodulate symbols with high precision using delay detection even if there is no clock synchronized precisely on the receiving side (described in detail later).

The differential encoding unit 203 includes an XOR circuit 204 in which an information ID 103 whose frequency spectrum is spread by a multiplier 202 is input to one of input terminals and an XOR circuit 204 in which the output of the XOR circuit 204 is delayed one chip, And a one-chip delay circuit 205 for returning to the other input terminal of the circuit 204. The output of the XOR circuit 204 is delayed by one chip and fed back to the other input terminal of the XOR circuit 204 so that the XOR circuit 204 and the input chip of the frequency ID spread information ID 103 and the input chip of the XOR circuit 204 Quot;) as the differential code. That is, in the differential code, the absolute value of each chip of the information ID 103 in which the frequency spectrum is diffused is replaced with a code indicating the phase coincidence or inconsistency with the immediately preceding differential code chip. Thus, by comparing two consecutive chips on the receiving side, it is possible to restore the information ID 103 in which the frequency spectrum has been spread even if there is no clock synchronized with the transmitting side precisely.

The differential code output from the XOR circuit 204 is input to the upsampling unit 206. The upsampling section 206 divides each sample of the code string into which the differential code is inputted into a plurality of samples and processes the waveform so that the demodulation is possible on the receiving side even when the sign is expanded or contracted by the Doppler shift.

The differential code up-sampled in the up-sampling unit 206 is input to the LPF 207. [ The LPF 206 is a filter that limits the band of the baseband signal and limits the band of the baseband signal while suppressing the inter-chip interference, and is called a Nyquist filter. A Nyquist filter is a filter whose impulse response is linked at a symbol rate (passes zero) and consists of an FIR filter, commonly referred to as a cosine roll-off filter. The order of the filter, the roll-off rate (?), Etc. are determined according to the conditions to be applied.

In this embodiment, the terminal device 22 receiving the acoustic ID 104 also performs filtering with the LPF 254 (see Fig. 6). Therefore, the LPF 207 of Fig. 4 and the LPF 254 of Fig. 6 ) Is composed of a root raised cosine roll-off filter so as to be a complete Nyquist filter.

The signal band-limited and waveform-shaped by the LPF 207 is multiplied by the carrier signal generated by the carrier signal generator 209 in the multiplier 208 and shifted to a signal in the frequency band of 18 to 20 kHz shown in Fig. 2 . The signal shifted to the frequency band of 18 to 20 kHz and the signal output from the sound ID conversion section 15 is input to the sound synthesis section 16 as the sound ID 104. [

The speech synthesizer 16 is an adder for synthesizing the acoustic signal by adding the acoustic ID 104 to the broadcast speech signal which is the speech signal of the main content 101. [ The speech synthesizer 16 adjusts the broadcast speech signal and the sound ID 104 to the same sampling frequency, adds the broadcast speech signal and the sound ID 104, and outputs a broadcast speech signal in which the sound ID 104 is superimposed do. The temporal synthesis position of the broadcast audio signal (main content 101) of the sound ID 104 is suitable near the time position of the video and audio extracted by the content analyzing unit 12 and extracted from the keyword 102.

The main content 101 including the broadcast audio signal in which the sound ID 104 is superimposed is input to the transmitter 10 and transmitted as a UHF band radio wave signal as a television broadcast. This radio wave signal is received by the television receiver 21 to reproduce video and audio. The video signal of the main content 101 is displayed on the display and the audio signal of the main content 101 is soundproofed from the speaker. As described above, this audio signal includes the sound ID 104. [ The soundproof sound ID 104 is received by the terminal device 22 held by the viewer 20.

[ The ID resolution server 41 is provided with an ID / URL correspondence table 41A and searches the ID / URL correspondence table 41A with the information ID 103 received from the terminal device 22, And returns it to the terminal device 22. The terminal device 22 having obtained the URL 141 accesses the sub-contents providing server 31 with the URL 141 to download and display the web advertisement 121. [

Fig. 5 is a block diagram of the terminal device 22. Fig. In this figure, only the portion related to the present invention of the smartphone, which is an example of the terminal device 22, is illustrated. The terminal device 22 includes a microphone 51, a control section 52, a network communication section 56, a storage section 57, an operation section 58, and a display section 59. The microphone 51 receives a sound signal including the sound ID 104 soundproofed from the speaker of the television receiver 21. [ The network communication unit 56 is a functional unit that accesses the communication network 5 such as the Internet, a local area network, or the like via a wireless communication antenna by wireless communication such as a Wi-Fi standard and / or a 3G (IMT- to be. The terminal device 22 communicates with the ID resolution server 41 or the sub-contents providing server 31 via the communication network 5. [ The communication network 5 is a communication network such as a mobile communication network, a gateway, or the Internet. The communication network 5 may be a single communication network, but a plurality of communication networks having different communication methods may be interconnected.

The control unit 52 functions as the sound ID demodulation unit 53, the URL acquisition unit 54 and the web browser 55 in cooperation with the application program. The sound ID demodulation unit 53 is a processing unit that extracts the sound ID 104 from the sound signal received by the microphone 51 and demodulates the sound ID 104 into the information ID 103. [

The control unit 52 has a central processing unit (CPU), a read only memory (ROM), and a random access memory (RAM). The CPU controls each unit connected to the control unit 52 by executing the control program stored in the ROM or the storage unit 57. [ The storage unit 57 stores various programs as a storage device such as a hard disk or a flash memory. The operation unit 58 has, for example, a plurality of keys, and when these keys are operated by the user, the operation unit 58 supplies a signal corresponding to the contents of the operation to the control unit 52. [ The control unit 52 determines the contents of the operation on the basis of this signal and performs processing. The display unit 59 includes a display such as a liquid crystal display or a memory such as a VRAM (Video Random Access Memory), and displays various images including images corresponding to radio waves received under the control of the controller 52, Display on the display. The display unit 59 also functions as a display screen of the web browser 55. [

6 is a block diagram of the sound ID demodulation unit 53. FIG. The audio ID demodulating unit 53 receives the A / D-converted audio signal received by the microphone 51. The input speech signal is input to the HPF 251. The HPF 51 is a high pass filter having a cutoff frequency in the vicinity of 18 kHz. The HPF 51 removes the audio frequency band signal corresponding to the audio signal of the main content 101 from the input audio signal, Is a filter for extracting only a signal of a frequency band of The signal component (signal component corresponding to the sound ID 104) extracted by the HPF 251 is input to the delay 252 and the multiplier 253. The delay time of the delay 252 is set to the number of clocks corresponding to one chip of the spreading code. That is, when the spread code (differential code) is up-sampled by the up-sampling unit 206 of the transmission-side sound ID conversion unit 15, the delay amount of the delay 252 is also N samples. The multiplier 253 multiplies the sample output from the HPF 251 and the sample output from the delay 252. This processing is delay detection processing. The spread code (frequency ID spread information ID 103) differentially encoded by the delay detection processing is converted into the original spreading code.

The characteristic of the delay detection processing is that it does not require the reproduction of the carrier signal in demodulation. As described above, by adopting the differential encoding on the transmission side and the delay detection on the reception side, it is possible to construct a communication system that is robust against frequency fluctuation and has a small processing load.

The multiplication output of the multiplier 253 is input to the LPF 254. The LPF 254 is a filter for filtering a carrier component to extract a baseband signal and filtering unwanted noise to improve the SN ratio. The LPF 254 is a filter for filtering the useless noise and is similar to the LPF (Nyquist filter) It is characteristic. As described above, the LPF 207 of the modulator and the LPF 254 are combined to form a filter having a root characteristic so as to have a complete Nyquist filter characteristic.

The output signal from the LPF 254 is input to the matched filter 255. [ The matched filter 255 is constituted by an FIR filter having a spreading code (PN), which is the same code string as that used for spreading the data code, on the transmitting side as a coefficient. The chip rate of the spreading code used for the coefficient is the same as the chip rate after upsampling on the transmission side. That is, the same code of the same spreading code (PN) is repeated in the matched filter 255 by the up-sampling rate. The matched filter 255 performs a convolution operation between the output waveform of the LPF 254 and the spreading code (PN), and outputs the correlation value.

The correlation value output from the matched filter 255 indicates a peak indicating a strong correlation in the period of the spreading code (PN), and the phase of the peak is phase-modulated by the transmission symbol. Therefore, the correlation values outputted by the matched filter 255 show the peaks of the positive sign and the negative sign respectively corresponding to 1 and -1 of the transmission symbol. The output of the matched filter 255 is input to the peak detector 256. The peak detector 256 detects a large peak in the vicinity of the period of the spread code PN and specifies a correlation peak. The specified correlation peak is input to sign determining section 257. [ The sign determining section 257 decodes the symbol from the peak phase and outputs it as the information ID 103.

The information ID 103 obtained by demodulating the acoustic ID 104 extracted from the voice signal by the acoustic ID demodulation unit 53 is input to the URL acquisition unit 54. [ The URL acquisition unit 54 controls the network communication unit 56 to communicate with the ID resolution server 41 and obtains the URL 141 corresponding to the information ID 103 from the ID resolution server 41. [ This URL 141 is a part corresponding to the sound ID 104 (or the information ID 103) superimposed on the audio signal of the main content 101 (television program) being reproduced by the television receiver 21 at that time And the URL 141 of the content 121. The URL 141 is input to the web browser 55. The web browser 55 accesses the sub-content providing server 31 using the URL 141 and downloads and displays the web advertisement as the sub-content 121. [

"Management Center (4)"

The management center 4 has a management server 40 and an ID resolution server 41. The advertiser 30 of the sub-content 121 uploads the created sub-content 121 to the sub-content providing server 31. The sub-contents providing server 31 may be a general web server. Then, the advertiser 30 makes an entry in the management center 4 for the link advertisement providing service for this sub-content 121. [ The management server 40 includes a management database (not shown) having a configuration substantially similar to that of the entry database 14 in Fig. 3, and at least information IDs , Upper limit unit price and budget are registered.

The management server 40 receives the entry information 122 and the URL 141 from the advertiser 30 and accepts an entry of the sub-content 121. [ The management server 40 issues the information ID 103 to the sub-content 121 which has accepted the entry. The information ID 103 is issued unique to each of a plurality of sub-contents 121 which are at least the entry at that time. The information ID 103 is registered in the management database together with at least the upper limit unit price and the budget of the entry information 122. The entry information 122 (at least the upper limit unit price and the information necessary for the selection rule) and the information ID 103 are transmitted to the advertisement selecting unit 13 of the link information selection superimposing unit 11 and registered in the entry database 14 . The management server 40 also transmits the information ID 103 and the URL 141 of the sub-content 121 to the ID resolution server 41 in association with each other. The ID resolution server 41 registers the information ID 103 and the URL 141 of the sub-content 121 in the ID / URL correspondence table 41A.

As described above, the ID resolution server 41 registers the information ID 103 transmitted from the management server 40 and the URL 141 in association with each other in the ID / URL correspondence table 41A. Upon receiving the information ID 103 from the terminal device 22, the ID resolution server 41 searches the ID / URL correspondence table 41A by using the information ID 103 as a key, and associates the information ID 103 with the information ID 103 Reads the registered URL 141, and returns it to the terminal device 22. [

The ID resolution server 41 notifies the management server 40 that the information ID 103 has been resolved. The management server 40 accesses the URL 141 of the sub-content 121 to determine whether the terminal device 22 has accessed the resolution number of the information ID 103, that is, the number of times the URL 141 has been transmitted to the terminal device 22 That is, the number of times the sub-content 121 is viewed by the terminal device 22, and calculates the fee of the link advertisement providing service based on the count value. The management server 40 sets the billing rate corresponding to the entry selection information 105 received from the information selecting unit 13 of the link information selection superimposing unit 11 to the " .

The budget (yen) stored in the management database of the management server 40 is the upper limit amount of the charge that the advertiser 30 can pay for the entry of one sub-content 121. [ When the total sum of the billing rates calculated in accordance with the resolution of the information ID 103 described above reaches the budget, the management server 40 subsequently determines that the sub-contents 121 corresponding to the information ID 103 correspond to the corresponding And manages entries of the sub-contents 121 so that even when the keyword 102 is inputted, the sub-contents 121 are not bidded or selected.

The management server 40 charges the amount of the contract price to the advertiser 30 every time the information ID 103 is resolved in the URL 141. [ This billing request may be made when the advertisement fee reaches the budget of the entry or may be performed in units of the advertisement selection unit for one keyword 102. The billing process may be a member process, but the billing account or the credit card of the advertiser 30 may be charged online.

&Quot; Operation of each part of the advertisement providing system "

Hereinafter, the processing sequence of the main components of the advertisement providing system will be described with reference to the flowcharts of FIGS. 7 and 8. FIG. 7 (A) to 7 (C) are flowcharts showing the operation of the management server 40. Fig. 8 (A) to 8 (C) are flowcharts showing the operations of the advertisement selecting unit 13, the terminal device 22, and the ID resolution server 41, respectively.

7 (A) is a flowchart showing an entry acceptance operation of the management server 40. Fig. The advertiser 30 transmits entry information and the like to the management server 40 of the management center 4 and enters the link advertisement providing service. The management server 40 receives the entry information 122 from the advertiser 30 and the URL 141 of the sub content 121 and receives the entry of the sub content 121, 121 to the information ID 103 (S11). The management server 40 then transmits the received entry information 122 and the assigned information ID 103 to the advertisement selecting unit 13 (S12). The transmitted entry information 122 and the information ID 103 are registered by the information selecting unit 13 in the keyword field specified in the entry database 14 (described in the entry information 122). The management server 40 also transmits the information ID 103 and the URL 141 of the sub-content 121 to the ID resolution server 41 (S13). The transmitted information ID 103 and the URL 141 are registered in the ID / URL correspondence table 41A by the ID resolution server 41. [

The management server 40 receives the entry selection information 105 from the information selection unit 13 of the link information selection superimposing unit 11 and transmits the information ID included in the received entry selection information 105 and the winning bid The unit price is stored in a predetermined area of a storage means or management database not shown. These stored information IDs and the winning bid price are used in the calculation of the billing fee.

Fig. 8 (A) is a flowchart showing the advertisement selection operation of the information selector 13. Fig. When the keyword 102 indicating the content of the main content 101 is inputted from the content analyzing unit 12 to the information selecting unit 13 at S40, the information selecting unit 13 corresponds to the input keyword 102 (Step S41). The sub-content 121 is selected based on the above-described selection rule and automatic bidding. The information selecting section 13 outputs the information ID 103 indicating the sub-content 121 selected in step S41 to the sound ID converting section 15 (S42) And the information including the winning bid amount to the management server 40 as the entry selection information 105 (S43).

7B is a flowchart showing an entry selection information processing operation of the management server 40. Fig. When the management server 40 receives the entry selection information 105 of any one of the sub-contents 121 from the information selector 13 (S20), the management server 40 stores the entry selection information 105 (S21). The entry selection information 105 is used for calculating the advertisement fee of the sub-content 121, and the like. The management server 40 notifies the ID resolution server 41 that the resolution of the information ID 103 of the selected sub-content 121 is permitted for a predetermined time T (S22).

8B is a flowchart of a sub-content acquisition program showing the operation of the terminal device 22 from the time when the terminal device 22 receives the sound ID 104. FIG. This processing shows the operation of the control unit 52 of the terminal device 22 and includes the operations of the sound ID demodulation unit 53, the URL acquisition unit 54 and the web browser 55. [ In the terminal device 22, this sub-content acquisition program is in a state in which it is resident or executed in the background. The sound ID demodulation unit 53 extracts the sound ID 104 included in the sound signal from the television receiver 21 received by the microphone 51 and demodulates the sound ID 104 into the information ID 103 (S50). The URL acquisition unit 54 transmits the demodulated information ID 103 to the ID resolution server 41 in step S51 and receives the URL 141 of the sub content 121 as the response in step S52. The web browser 55 accesses the sub content provision server 31 using the URL 141 received by the web browser 55 and downloads and displays the sub content 121 at step S53.

Fig. 8C is a flowchart showing the operation of the ID resolution server 41. Fig. This processing operation is executed for the predetermined time for the information ID 103 when the resolution of the information ID 103 is permitted from the management server 40 (see S22). When the ID resolution server 41 receives the information ID 103 from the terminal device 22 in step S60, the ID resolution server 41 searches the ID / URL correspondence table 41A with the information ID 103, (S61). Then, the ID resolution server 41 returns the read URL 141 to the terminal device 22 (S62), and notifies the management server 40 that the information ID 103 has been resolved (S63 ).

The predetermined time T permitting the resolution of the information ID 103 is set for setting the time limit for the ID resolution in order to follow the content of the main content 101 changed and changed instantaneously. A sufficient time is set for the terminal device 22 that has received the sounded sound ID 104 to resolve the information ID 103 to display the sub-content 121. [ Specifically, about 5 minutes is suitable. However, the predetermined time is not limited to 5 minutes but may be longer or shorter. It is also possible to continue until the next entry selection information 105 is transmitted from the information selection unit 13. [ The ID solving server 41 may notify the management server 40 of the fact that the ID solving server 41 has performed the elapsing of the allowance time and the management server 40 performs the management of the predetermined time, The management server 40 may notify the ID resolution server 41 of the elapsed time.

FIG. 7C is a flowchart showing an entry management operation of the management server 40. FIG. When the management server 40 permits the ID solving server 41 to solve the information ID 103 (see S22), the management server 40 executes this processing for the permitted information ID 103. [

When the management server 40 receives the notice of solving the information ID 103 from the ID resolution server 41 (YES in S30), the management server 40 sets the number of ID resolutions in the current entry selection of the information ID 103 (S31). Then, the management server 40 accumulates the winning bid price described in the current entry selection information 105 and the measured ID resolution count, and calculates the current billing fee for the selected sub-content 121 ( S32). It is determined whether or not the total sum of the current billing rate and the billing fee based on the selection of the previous entry reaches the budget of the sub-content 121 (S33). When the total of the billing rates has not yet reached the budget (NO in S33), the management server 40 retreats the processing to S30 and determines whether or not the next ID resolution notice is received. On the other hand, when the total of the billing rates has reached the budget (YES in S33), the management server 40 notifies the information selection unit 13 of the link selection overlap unit 11 of the entry URL information 141 of the sub-contents 121 to the ID resolution server 41 (S34), and also instructs the ID resolution server 41 to delete the information ID 103 and the URL 141 from the ID / URL correspondence table 41A (Step S35). As a result, the sub-contents 121 in which the total sum of the billing charges has reached the budget are later selected by the information selecting unit 13 or the ID solving server 41 solves the ID, .

When the billing rate does not reach the advertisement budget and the predetermined time (the time for allowing the ID resolution server 41 to solve the information ID 103) has elapsed (YES at S36), the management server 40 The current billing rate is accumulated in the total sum of the non-settlement charge fees related to the selection of the previous entry (S37), and stored in the storage means or the predetermined area of the management database (not shown), and the entry management operation is terminated.

9 shows the hardware of the link information selection superimposing unit 11 (content editing apparatus) in the broadcasting station 1, the management server 40 in the management center 4 or the ID resolution server 41 or the sub- Fig. 2 is a block diagram briefly showing a configuration. Fig. Unlike the terminal device 22, these devices and servers are not directly operated by the user, and thus it is not necessary to form the display portion or the operation portion. The control unit 403 has a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory). The CPU controls each unit connected to the control unit 403 by executing the control program stored in the ROM or the storage unit 404. The storage unit 404 is, for example, a storage device such as a hard disk or a flash memory, and stores various programs and various tables. The signal input from the input unit 401 is input to the control unit 403 and performs various processes on the input signal or performs various processes on the basis of the input signal and outputs the processing result to the output unit 402. [ . The output unit 402 outputs the output signal to the outside. In this case, the input unit 401 or the output unit 402 itself may be configured to communicate with an external device, or the input unit 401 or the output unit 402 may be connected to another communication device, As shown in FIG.

"Variations"

The contents of the above-described embodiment may be modified as follows. The modifications shown below may be carried out in combination as required.

In the above operation of the management center 4, by using a log (communication record) such as the number of times that the ID resolution server 41 solved the information ID 103 to the URL 141, The number of accesses to the site, etc. may be calculated, the advertisement effect may be measured using this log (communication record), and the measurement result may be presented to the client.

The link information superposition unit 11 may analyze the main content 101 before broadcasting. In this case, the keyword 102 for each scene of the main content 101 is generated in advance before the broadcast and stored together with the time position (time code or the like) in the main content 101. [ A means for storing the keyword and the time code is provided in the position of the content analyzing unit 12 in Fig. 1, and when the main content 101 is broadcast (transmitted) from the broadcasting station 1, (102) to the information selector (13).

A plurality of terminal devices 22 simultaneously receive the sound ID 104 and the access to the ID resolution server 41 is concentrated and the sub-contents providing server 31 also receives the sound ID 104, There is a possibility that congestion may occur. A function for generating a random wait time is set in the terminal device 22 (URL acquisition unit 54), and after waiting for the waiting time, the ID resolution server 41 and the sub-contents providing server 31 May be accessed.

In the above embodiment, the terminal device 22 accesses the sub-contents providing server 31 without displaying the operation of the viewer 20 when demodulating the acoustic ID 104 to display the sub-contents 121 However, the terminal device 22 may access the sub-contents providing server 31 after receiving the operation of instructing (permitting) the sub-contents providing server 31 to access.

In this embodiment, the advertisement is described as a representative example as the sub-content 121, but the information to be provided is not limited to the advertisement. As the information related to the content of the main content 101, for example, local information, a cooking recipe, or the like may be used.

The manner in which the information ID 103 is added to the main content 101 is not limited to the sound ID 104. [ For example, it is also possible to use a subcode or a data broadcast of a voice signal. However, the method of using the sound ID 104 is suitable for addition to the existing broadcasting system because the TV receiver 21 does not need to set a new function. In addition, even when the acoustic ID 104 is used, it is sounded as a sound wave from a speaker and is received by the terminal device 22, and an acoustic signal is transmitted through a wired or wireless transmission system such as an audio cable or Bluetooth (registered trademark) .

Further, instead of the sound ID 104, the voice fingerprint information of the main content 101 may be used. That is, by using the voice fingerprint information to identify the main content of the distribution source (broadcasting station), the program, and the CM of the main content and use it as the identification information (ID code) instead of the information ID 103, 41 may be accessed.

The present invention is not limited to this. For example, radio broadcasts, disaster prevention broadcasts in the area, intra-site broadcasts in facilities, and broadcasts (Internet broadcasts) through communication networks, It may be a broadcast form. Further, the terminal device in the present invention is not limited to the smart phone 2. [ For example, various devices capable of being held by the viewer 20 (user), such as a portable telephone or a tablet terminal, a PDA (Personal Digital Assistant), a mobile computer, a game machine, Can be used.

A part of the link information selection superimposing section 11 such as the content analyzing section 12, the information selecting section 13 or the sound ID converting section 15 may be provided outside the broadcasting station 1. For example, it may be installed in the management center 4. The broadcasting station 1 may be a relay station, or may be a broadcasting station or a broadcasting station that rearranges and distributes the main content 101 broadcast or distributed by another broadcasting station or a plurality of broadcasting stations or a content server. For example, when these (a part of the link information selection superimposing unit 11, for example, the content analyzing unit 12 and the information selecting unit 13) receive a plurality of main contents 101, The main content editing apparatus or the broadcasting and distributing transmitting apparatus may be constituted by combining the main contents 101 and processed by the contents analyzing unit 12 and the information selecting unit 13. [

Part or all of the link information selection superimposing unit 11 and the management server 40, the ID resolution server 41 or the sub-contents providing server 31 can be realized by virtualization technology as appropriate, Or may be realized by the virtualization server.

In the present embodiment, the ID resolution server 41 has the ID / URL correspondence table 41A. However, the ID / URL correspondence table 41A may be provided by the management server 40. [ In this case, when the sub-content 121 is selected, the management server 40 transmits the pair of the information ID 103 and the URL 141 of the sub-content 121 to the ID resolution server 41 , The ID resolution server 41 may keep the pair of the information ID 103 and the URL 141 of the sub-contents 121 transmitted for the predetermined time period for which the ID resolution is permitted.

In the present embodiment, the information ID 103 is superimposed as the sound ID 104 in the main content 101, but the URL 141 of the sub-content 121 is converted into the sound ID 104, . With this configuration, the processing of the ID resolution server 41 becomes unnecessary.

It is also possible to convert the keyword 102 output by the content analyzing unit 12 into the sound ID 104 and superimpose the keyword 102 on the main content 101 instead of the information ID 103. [ In this case, the information selection unit 13 is formed at the position of the ID resolution server 41 in Fig. The information selecting unit 13 selects the sub content 121 based on the keyword 102 transmitted from the terminal apparatus 22 and sends the URL 141 to the terminal apparatus 22 instead of the information ID 103 Reply is good. In this case, the terminal device 22 transmits the personal information such as the sex, age, and residence of the viewer 20 to the information selecting section 13 together with the keyword 102, It is also possible to select the sub-content 121 suitable for each viewer 20 based on the information. When the terminal device 22 acquires the positional information of the GPS and the like and uses the positional information as a parameter for selecting the sub-content 121, Can be provided. These pieces of personal information and position information may be used in combination. The ID resolution server 41 or the sub-contents providing server 31 may change the selection of the contents of the sub-contents 121 based on the personal information and the position information.

It is also possible that the broadcast station 1 adds time information indicating the current time (broadcast time of the broadcast station 1) at that time in addition to the information ID 103 as the sound ID 104. When the main content 101 is later reproduced on the recorded main content 101 by allowing the ID resolution server 41 to select the sub-content 121 based on the broadcast station ID 103 and the time information, It is possible to provide the proper sub-contents 121 by demodulating the information ID 103 and the time information from the sub-contents.

In addition, the information content in the present invention is not limited to the sub-content 121 displayed on the display. The information content may be information provided by video, sound, vibration or the like by various output means such as soundproofing by a speaker, vibration by a vibrator, display by a light emitting body, or the like.

(Second Embodiment)

&Quot; Overview of content providing system "

10 is a diagram for explaining a configuration of a content providing system according to a second embodiment of the present invention. This content providing system is provided with a sub-content 1121 (second content data; web advertisement) related to the content of each scene of the main content 1101 (first content data; television program) (1022) of the web content providing system. In the present embodiment, for example, when a television program displays a scene of drinking a beer or other beverage, a web advertisement (sub-contents 1121) of a beer company, a beer restaurant, . A web content providing service for providing a web advertisement in a push-type form linked to the television program is hereinafter referred to as a " link advertisement providing service ". This link advertisement providing service is performed for web advertisements that have been previously submitted (entered). Here, the television program (main content 1101) is broadcast from the broadcast station 1001, and the television receiver 1021 receives the television program (main content 1101) and plays it back toward the viewer 1020. In the present embodiment, the television program refers to the entire content to be broadcasted from the broadcasting station 1001, and includes not only a television program main body but also a television commercial (television CM). When the viewer 1020 holds the terminal device 1022 and the viewer 1020 watches the television program, the terminal device 1022 is also located near the television receiver 1021 (which is soundproofed from the television receiver 1021) The distance to which a voice can be received).

When the ID resolution server 1041 receives the broadcast station ID 1103 from the terminal device 1022 (S1060), it searches the ID / URL correspondence table 1041A with the broadcast station ID 1103 and reads the corresponding URL 1141 (S1061). Then, the ID resolution server 1041 returns the read URL 1141 to the terminal device 1022 (S1062), and notifies the management server 1040 that the broadcast station ID 1103 has been resolved (S1063 ).

Since the effective time T for allowing the ID resolution server 1041 to solve the broadcast station ID 1106 with respect to one URL 1141 follows the content of the main content 1101 which is changed every moment and changed, It is possible to set a time limit for setting the time limit for the sub-content 1121 to a time when the terminal device 1022 receiving the sound ID 1104 soundproofed from the television receiver 1021 solves the broadcast station ID 1103 and displays the sub- Respectively. Specifically, about 5 minutes is suitable. However, the effective time is not limited to five minutes, and may be longer or shorter. Alternatively, the next advertisement selection information 1105 may be transmitted from the advertisement selection unit 1013 until the next advertisement selection information 1105 is transmitted. The ID resolution server 1041 may notify the management server 1040 that the ID resolution server 1041 has performed the validity time management and the management server 1040 may perform management of the validity time, The management server 1040 may notify the ID resolution server 1041 of this fact.

Fig. 13C is a flowchart showing the entry management operation of the management server 1040. Fig. When the management server 1040 permits the ID resolution server 1041 to resolve the broadcast station ID 1103 (see S1022), the management server 1040 executes this processing for the permitted broadcast station ID 1103. [

When the management server 1040 receives notification of solving the broadcast station ID 1103 from the ID resolution server 1041 (YES in S1030), the management server 1040 transmits the current sub-content 1121 (URL 1141 )) Is counted (S1031). The management server 1040 multiplies the winning bid price described in the advertisement selection information 1105 acquired in the present ID settlement by the counted number of ID resolutions and selects the sub-content 1121 in the present session of the selected sub- The advertisement fee is calculated (S1032). It is determined whether the sum of the amount of the advertisement fee in the current session and the total of the advertisement fee in the previous session reaches the advertisement budget of the sub-content 1121 (S1033). When the total of advertisement fees has not yet reached the advertisement budget (NO in S1033), the management server 1040 returns the processing to S1030 and determines whether or not the next ID resolution notice is received. On the other hand, when the total of the advertisement fees reaches the advertisement budget (YES in S1033), the management server 1040 notifies the advertisement selection unit 1013 of the link information selection unit 1006 of the sub- The URL 1141 of the sub-content 1121 and the broadcast station ID 103 are also stored in the ID / URL correspondence table 1041 to the ID resolution server 1041, (Step S1035). As a result, the sub-contents 1121 in which the total sum of the advertisement fees have reached the budget are stored in the sub-contents 1121 so as not to be selected by the advertisement selecting unit 1013 or to be resolved by the ID solving server 1041 Is managed.

When the advertisement fee does not reach the advertisement budget and the valid time T (the time for allowing the transmission of the URL 1141 in response to the broadcast station ID 1103 in the ID resolution server 1041) has elapsed (S1036 YES), the management server 1040 accumulates the current advertisement fee to the total amount of the advertisement charges up to the previous time (S1037), stores the result in a predetermined area of a storage means or an advertisement management database (not shown) And terminates.

"Variations"

The contents of the above-described embodiment may be modified as follows. The modifications shown below may be combined as needed.

In the above operation of the management center 1004, by using the log (communication record) such as the number of times the ID resolution server 1041 resolved the broadcast station ID 1103 to the predetermined URL 1141, ), And the advertisement effect may be measured using this log (communication record), and the measurement result may be presented to the client.

15 is a diagram showing an embodiment in the case where an adapter is provided in the television receiver 1021. Fig. In the case where the broadcasting station 1001 does not broadcast the broadcast station ID 1103 in a superimposed manner on the broadcast signal, it is sufficient to generate and add the station ID 1103 to the television receiver 1021 for sounding. In this case, as shown in Fig. 15, a station ID soundproofing apparatus 1070 is provided as an adapter in the television receiver 1021. [ The station ID soundproofing apparatus 1070 is constituted by a sound ID converting section 1071, an audio circuit 1072 and a speaker 1073. [ The sound ID conversion unit 1071 acquires the identification information (broadcast station ID 1103) of the broadcast station currently received by the television receiver 1021 via the HDMI and converts the broadcast station ID 1103 into the sound ID 1104 And inputs it to the audio circuit 1072. The interface for acquiring the broadcast station ID 1103 from the television receiver 1021 is not limited to HDMI, and may be a USB, for example. The audio circuit 1072 amplifies the sound ID 1104 and then sounds sound from the speaker 1073 toward the terminal device 1022. [ The configuration of the sound ID conversion unit 1071 may be similar to that of the sound ID conversion unit 1015 shown in Fig. The broadcasting station ID soundproofing apparatus 1070 can also transmit the broadcasting station ID 1103 without converting the broadcasting station ID 1103 acquired from the television receiver 1021 into the sound ID 1104 A broadcasting station ID transmitting apparatus (not shown) configured so as to be transmitted by radio wave or optical medium, which is a medium other than sound, may be used.

15, the station ID soundproofing apparatus 1070 is connected to the television receiver 1021 as an adapter, but the function of the station ID soundproofing apparatus 1070 may be incorporated in the television receiver 1021. [ In this case, the broadcast station ID 1103 may be sounded from the same loudspeaker together with the broadcast sound, or may be soundproofed from a separately installed loudspeaker.

The station ID soundproofing apparatus 1070 of the modification shown in Fig. 15 is provided with a speaker and configured as a device for transmitting the sound ID 1104 using air (gas) as a medium. However, if the terminal apparatus 1022 can detect solid or liquid vibration, the sound ID 1104 may be transmitted using solid or liquid as a medium.

A plurality of terminal apparatuses 1022 simultaneously receive the sound ID 1104 and the access to the ID resolution server 1041 is concentrated and the sub-contents providing server 1031 There is a possibility that congestion may occur. Thus, a function for generating a random wait time in the terminal device 1022 (URL acquisition unit) is set, and after waiting for this waiting time, the ID resolution server 1041 and the sub-contents providing server 1031 may be accessed good.

In the above embodiment, the terminal apparatus 1022 accesses the sub-contents providing server 1031 without displaying the operation of the viewer 1020 when demodulating the sound ID 1104, and displays the sub-contents 1121 However, the terminal apparatus 1022 may access the sub-contents providing server 1031 after receiving an operation of instructing (allowing) access to the sub-contents providing server 1031. [

In this embodiment, the advertisement is described as a representative example, but the information to be provided is not limited to the advertisement. As the information related to the contents of the main contents 1101, for example, local information, a cooking recipe, or the like may be used.

The addition manner of the broadcast station ID 1103 to the main content 1101 is not limited to the sound ID 1104. [ For example, it is also possible to use a subcode or a data broadcast of a voice signal. However, the method of using the sound ID 1104 is suitable for the case where it is added to the existing television watering system because the new function is not required to be set in the television receiver 1021. [ In addition, even when the acoustic ID 1104 is used, it is sounded as sound from the speaker (not shown) and is sounded by the terminal device 1022, as well as sound signals through a wired or wireless transmission path such as an audio cable or Bluetooth May be transmitted.

Further, the voice fingerprint information of the main content 1101 may be used instead of the sound ID 1104. That is, broadcasting contents such as distributors (broadcasting stations), programs, and CMs of the main contents 1101 are specified using the voice fingerprint information, and the broadcasting contents are used as identification information (ID codes) instead of the broadcasting station IDs 1103, The resolution server 1041 may be accessed.

In this embodiment, the television broadcasting is described as an example. However, the present invention is not limited to this. For example, various types of broadcasting such as radio broadcasting, disaster prevention broadcasting in the area, Distribution, and broadcasting. Further, the terminal device 1022 in the present invention is not limited to a smart phone. For example, it is possible to use a mobile phone or a tablet terminal, a PDA (Personal Digital Assistant), a mobile computer, a game machine, a set-top box, or the like as the terminal device 1022 of the present invention.

The link information selection unit 1006 may be installed inside the broadcasting station 1001 to receive the main content 1101 with a different transmission channel from the general television receiver 1021. [ For example, the main content 1101 broadcasted by terrestrial digital broadcasting may be cable-input as a data stream without radio waves.

Further, the link information selection unit 1006 may be provided in the management center 1004. All or a part of the content analyzing unit 1012, the advertisement selecting unit 1013, and the advertisement entry database 1014 of the management server 1040, the ID resolution server 1041 and the link information selecting unit 1006 may be integrated (In the same computer system).

Part or all of the broadcast station ID superposition unit 1011 and the management server 1040, the ID resolution server 1041 or the sub-content provision server 1031 in the configuration of the present content providing system can be appropriately realized by the virtualization technology Or may be realized by physically separate apparatuses, or individual functions may be realized by the virtualization server.

In addition to the station ID 1103, the broadcasting station 1001 or the broadcasting station ID soundproofing apparatus 1070 displays the current time (the broadcasting time of the broadcasting station 1 or the soundproofing time of the station ID soundproofing apparatus 1070) The time information may be transmitted as the sound ID 1104. When the main content 1101 is later reproduced on the recorded main content 1101 by allowing the ID resolution server 1041 to select the sub-content 1121 based on the broadcast station ID 1103 and the time information, It is possible to provide appropriate sub-contents 1121 by demodulating the broadcast station ID 1103 and the time information.

When the personal information of the user 1020 is registered in the terminal apparatus 1022 and this personal information is used as a parameter for selecting the sub-contents 1121, for example, can do. When the terminal device 1022 acquires position information of a GPS or the like and uses the position information as a parameter for selecting the sub-content 1121, it provides an optimal advertisement to the residence or the current position of the user 1020 . These pieces of personal information and position information may be used in combination. The ID resolution server 1041 or the sub-contents providing server 1031 may change the selection of the contents of the sub-contents 1121 based on the personal information and the position information.

Although only one broadcast station 1001 and one link information selection unit 1006 are shown in this embodiment, a plurality of broadcast stations 1001 may be used. The link information selection unit 1006 may be configured to receive the main content 1101 of the plurality of broadcast stations 1001 and output the advertisement selection information 1105. In addition, a separate link information selection unit 1006 may be provided for each broadcast station 1001. [
