1 is a configuration diagram of a content search service system according to an embodiment.

In the following, the content may be a TV broadcast program. Hereinafter, the TV broadcast program will be outlined as "program ". Alternatively, the content may be a radio program, a satellite broadcast program, a video and music, and the like.

The content search service system 100 includes a computing device 110 for receiving sound signals of a program and transmitting the sound data to the recognition service providing system 120, a search device for searching the information of the corresponding content based on the transmitted sound data, A recognition service providing system 120 for transmitting the content information to the computing device 110 and a recognition information generating system 130 for storing the content information in association with the original sound signals of the content.

The content information may include information related to the content, e.g., content metadata of the content. Further, the content information may include content formation information.

The content organization information may be information related to the combination of broadcasting of the content. For example, the content organization information may include an identifier (ID) of a content, a provider of the content, a content name, a start time of the content, and an end time of the content.

The recognition service providing system 120 may receive the sound data from the computing device 110 and may search the recognition information generation system 130 for the content information of the content corresponding to the transmitted sound data, To the device (110).

The recognition information generation system 130 may receive the original sound signal of the program and the information on the content formation. The recognition information generation system 130 may store the original sound signal as digital data in association with the corresponding content information. The recognition information generation system 130 may store information of a part of the original sound signal when storing the associated information. The information of a part of the original acoustic signal may include at least one of a finger print and a water mark in the original acoustic signal. The recognition information generation system 130 can process and store information inputted in real time without delay.

In step 140, the recognition service providing system 120 may receive acoustic data from the terminal. The terminal may be a device capable of receiving sound. For example, the terminal may include a computing device 110, a smart device 210 described below with reference to FIG. 2, a cellular phone, and the like. The computing device 110 may be coupled to the recognition service providing system 120 via the Internet.

In step 145, the recognition service providing system 120 can search for content that matches the acoustic data received from the recognition information generation system 130. [

In the process of outputting the sound of the content, the original sound may be deformed and output due to noise, loss in the compression process, loss in the decompression process, loss in the analog output, and the like. In addition, the original sound can be deformed in the course of inputting the outputted sound to the terminal. Thus, the sound represented by the sound data may not coincide with the original sound of the content. Means that the sound represented by the sound data is identified as having the same content as the original sound of the content. Or "match" may mean the extent to which the sound of the sound data is not the same as the original sound of the content, but can uniquely correspond to the original sound. Or "match" may mean the extent to which the viewer can perceive the sound of the sound data and the original sound of the content as identical. Or "match" may mean that the sound of the sound data may be considered to be the output and re-input of the original sound of the content.

Using the searched content, the recognition service providing system 120 can search the contents information of the searched contents in the recognition information generation system 130. [

The content information may include content organization information of the searched content. The content information may include a reproduction time at which a circular sound corresponding to the sound data out of the searched contents is output.

The recognition service providing system 120 can correct the reproduction time according to the time used for searching when transmitting the current reproduction time of the contents as part of the contents information. That is to say, the reproduction time may be the time corrected according to the time used for the search.

In step 150, the recognition service providing system 120 may transmit content information about the searched content to the terminal.

2 is a block diagram of a content search service system for transmitting content information and supplementary service information results according to an embodiment.

The content search service system 100 of the content may include a smart link matching system 220, a smart link indexing system 230, a smart link service manager 240 and a smart link service web server 250.

In step 261, the smart link indexing system 230 may obtain the original acoustic signal from the broadcast image and sound 260.

At step 262, the smart link indexing system 230 may receive content programming information from the content programming information and transmission operating system 270.

The smart link indexing system 230 may correspond to the recognition information generation system 130 described above in FIG. The smart link indexing system 230 may store the original sound signal received at step 261 and the content programming information received at step 262 in association with each other.

 The smart link indexing system 230 may create a separate database for content redundancy if the original sound signal is a content overlapping portion. Here, the content duplication portion may be a part common to a plurality of contents managed by the contents search service system 100 of FIG. The common part may also be content.

For example, the plurality of contents may include a series of TV broadcast programs. In other words, the broadcast sequences constituting a series of TV broadcast programs may be a plurality of contents. The plurality of contents may be contents related to each other in a name, a subject, a cast, a producer, a broadcasting company, etc. The content duplication part may be a plurality of contents having different broadcast times, such as an OST of the contents, an advertisement, Or a plurality of contents irrelevant to the content may have the same sound. One content may include a content full title, one or more full advertisements, a video that is the content of the content, one or more post-ads, and a post-content title. When a user views a content duplication part, it may be difficult for the user to watch the content of one or more contents including the content duplication part. Therefore, when the user watches the content duplication portion, the content duplication portion is specified, and information on the content duplication portion may need to be provided to the user.

In indexing the content including the content duplication portion, the smart link indexing system 230 can index the content information of the content and index the content information of the content duplication portion. That is, the content duplication part can be indexed separately from the content. Here, the content information of the content duplicated portion may include a content duplicate ID, an advertisement ID, an OST ID, and the like.

The indexed content information of the content can be stored for each content. The indexed content information of the content duplication portion can be separately stored according to the type of the content duplication portion. For example, the indexed content information of the content duplication portion can be classified and stored as OST, advertisement, full-content title, and content post-title.

The smart link indexing system 230 can extract unique features for each point in time of the original sound of the content being broadcast and can configure a fingerprint based on the extracted unique features. The smart link indexing system 230 may store fingerprint and content information together.

As described above, the content duplication portion can be indexed separately from the content. The smart link indexing system 230 may extract the fingerprint of the content from the original sound signal received in step 261 and index the content using the extracted fingerprint. In addition, the smart link indexing system 230 can extract the fingerprint in the content redundancy portion and index the content redundancy portion using the extracted fingerprint.

The steps 261 and 262 performed by the smart link indexing system 230 may be performed in any order. The smart link indexing system 230 may associate the original sound signal and the content information with each other after steps 261 and 262 are performed.

At step 271, the smart link service manager 240 may receive the content programming information from the content programming information and the transmission operating system 270. [

At step 272, the smart link service manager 240 may receive content metadata from a content management system (CMS). Here, the content metadata may mean a playback time of a content, a channel, a broadcast type, and the like. The type of broadcast may be either broadcast or rebroadcast.

The smart link service manager 240 may map the supplementary service information for the supplementary service related to the reproduction period of the part of the content to the reproduction period of the part of the content. Here, some of the playback sections may be included in the content information acquired based on the sound data. The starting point of a part of the reproduction section may be the reproduction time at which the original sound signal corresponding to the sound data in the contents is outputted.

For example, the supplementary service information may include information of a character and a position where the content is produced.

The service link service manager 240 can organize and manage the contents of the additional service provided to the user through the smart link service web server 250.

Steps 271 and 272 performed by the smart link service manager 240 may be performed in any order. The smart link service manager 240 may map supplementary service information related to a reproduction interval of a part of the content and a reproduction interval of a part of the content after the step 271 and the step 272 are performed.

In step 281, the smart device 210 may receive the sound of the content. The sound of the content may be TV sound.

At step 282, the smart link matching system 220 receives the sound data from the smart device 210. The smart link matching system 220 may correspond to the recognition service providing system 120 described above in FIG.

In step 283, the smart link matching system 220 may search for content based on the comparison of the received sound data and the original sound signals. The smart link matching system 220 can search for content that matches the sound data. The smart link matching system 220 may retrieve content by comparing the fingerprint in the audio data and the fingerprint of the content. In addition, the smart link matching system 220 can search for content by comparing the watermark in the audio data and the watermark of the content. Here, the fingerprint of the content may be a fingerprint of the original sound signal of the content. The watermark of the content may be a watermark of the original sound signal of the content.

In step 283, when the result of the comparison of the sound data and the original sound signal is a content duplication part, the smart link indexing system 220 can search contents and content duplication parts corresponding to the sound data.

As described above, the content duplication portion can be indexed separately from the content. For example, when the content is a program, the overlapping portion of the contents of the plurality of programs may correspond to the sound data. When the program ID indicates the program, and the content duplicate part ID indicates a content duplication part, the smart link indexing system 220 can retrieve a plurality of program IDs and a content duplicate part ID. Here, the plurality of program IDs may be the IDs of programs including the content duplication part corresponding to the sound data.

The smart link indexing system 220 can provide only a duplicate part ID of the retrieved plurality of program IDs and the content duplicated part ID as a result of the search. Therefore, at a later step, only the content duplication portion excluding the plurality of programs can be provided as a result of the search.

For example, when a user watches an OST of a program, the sound data of the OST may correspond to one or more programs including the OST and a content overlap portion of the one or more programs. The smart link indexing system 220 can detect the program IDs of one or more programs and the content ID of the OST, but can provide clear information by using only the content ID of the OST as a result of the search.

When the smart link matching system 220 sends the retrieved content to the smart link indexing system 230, the smart link indexing system 230 may retrieve the content information.

At step 283, the smart link matching system 220 may use a hybrid scheme that uses both immutable and variable data for content retrieval.

For example, the immutable data may be one or more of the ID of the content and the name of the content. Constant data can be embedded in the content as a watermark. The variable data may be metadata of the contents. The metadata may include a playback point of time, a channel, a main frame, or a return status of the content. The variable data can be inserted into the content as a fingerprint.

For example, the smart link matching system 220 can detect a watermark, which is constant data in the original sound of the content being broadcast, and can acquire the content information by using the detected watermark. The content information included in the watermark may include the ID of the content and the name of the content. The smart link matching system 220 can retrieve the playback time of the content and additional service information for the content by using the obtained content information and the fingerprint. By the hybrid scheme, the time used for retrieving the content information can be reduced more than the time used by the method using only the fingerprint.

At step 284, the smart link indexing system 230 may send the retrieved content information to the smart link matching system 220.

When the content overlapping portion is received, the smart link indexing system 230 transmits to the smart matching system 220 the content information of the overlapping portion of the plurality of content information searched at Step 283 and the content information of the content overlap portion .

At step 285, the smart link matching system 220 may send the retrieved content information to the smart device 210. The smart link matching system 220 may transmit content information for the retrieved content redundancy portion to the smart device 210. [

At step 286, the smart link service web server 250 may receive an additional service request for content from the terminal. The supplementary service request may be based on the content information transmitted to the terminal by the smart link service web server 250. The supplementary service request may include the playback time of the content.

At step 287, the smart link service web server 250 may receive an additional service request. Upon receiving the supplementary service request, the smart link service web server 250 can retrieve the supplementary service information from the smart link service manager 240. The smart link service web server 250 can retrieve the playback interval corresponding to the supplementary service request among the contents.

The additional service information may be related to the reproduction time of the content which is the content information. In other words, the smart link service web server 250 can retrieve the supplementary service information mapped with the playback interval corresponding to the playback time of the content included in the supplementary service request.

In step 288, the smart link service manager 240 may transmit the retrieved playback interval and the mapped supplementary service information to the smart link service web server.

In step 289, the smart link service web server 250 may transmit the supplementary service information mapped with the searched playback interval to the mobile station.

The smart link service manager 240 can be named and outlined as a service manager.

The smart link service web server 250 may be named and outlined as a service web server.

The smart link matching system 220, the smart link indexing system 230, the smart link service manager 240, and the smart link service web server 250 may be physically configured as one system. For example, the smart link matching system 220 and the smart link indexing system 230 may be implemented in a physically single first server. In addition, the smart link service manager 240 and the smart link service web server 250 may be implemented in a physically single second server. Alternatively, a single server of the system may perform all the functions of smart link matching system 220, smart link indexing system 230, smart link manager 240 and smart link service web server 250.

FIG. 3 is a configuration diagram of a content search service system for transmitting an additional service information result according to an embodiment.

3, the contents search service system 100 of FIG. 1 receives the sound data from the smart device 210 of FIG. 2 and transmits the additional service information to the smart device 210 based on the received sound data Fig.

The content search service system 100 includes a smart link matching system 220 of FIG. 2, a smart link indexing system 230 of FIG. 2, a smart link service manager 240 of FIG. 2, a smart link service web server 250 and the Smart Link Service Database (DB) 252 of FIG.

At step 310, the smart device 210 may receive input of a content sound.

At step 320, the smart link service web server 250 may receive the sound data from the smart device 210. [

In step 330, the smart link service web server 250 may request the smart link matching system 220 to search for the sound data 140.

At step 340, the smart link matching system 220 may retrieve content information from the smart link indexing system 230 using a fingerprint or watermark of the acoustic data. When a watermark and a fingerprint are used together, a hybrid method can be used.

The smart link indexing system 230 may include a registration system, a memory DB, and a fingerprint main DB. The registration system, the memory DB and the fingerprint main DB are described in more detail in the following embodiments.

In steps 310 to 330, the smart link indexing system 230 associates the original sound signal and the content schedule information of the broadcast image and sound 260 with the content schedule information transmitted from the transmission operation system 270, As shown in Fig. Steps 261 and 262 described above with reference to FIG. 2 may be performed between steps 310-330.

At step 350, the smart link indexing system 230 may send the retrieved content information to the smart link matching system 220.

At step 360, the smart link matching system 220 may send the retrieved content information to the smart link service web server 250.

In step 370, the smart link service web server 250 can search for supplementary service information in the smart link service DB 252 based on the content information transmitted from the smart link matching system 220. In addition, the smart link service web server 250 can search for a playback interval corresponding to the sound data in the content. The retrieval of the supplementary service information may be a retrieval of the supplementary service information mapped with some reproduction section including the reproduction time of the transmitted contents information.

In step 380, the smart link service DB may transmit the supplementary service information mapped in the retrieved playback section to the smart link service web server 250. [

In step 390, the smart link service web server 250 may transmit the supplementary service information mapped in the retrieved playback section to the smart device 210. [

Between steps 310-360), the smart link service manager 240 receives the content programming information from the content delivery information and delivery operating system 270 of FIG. 2 and receives the content metadata from the CMS 280 can do. The smart link service manager 240 may map the supplementary service information for the supplementary service related to the reproduction period of part of the content to a part of the reproduction period.

The smart link service manager 240 may store the mapped data in the smart link service DB 252. [ The smart link service DB 252 may be located inside or outside the smart link service manager 240. In other words, the smart link service manager 240 and the smart link service DB 252 may be physically one device or a separate device.

4 is a configuration diagram of a smart link indexing system according to an example.

The smart link index system 230 may include a registration system 410 and a fingerprint DB 420.

The registration system 410 may include a schedule synchronization manager 411, a real time fingerprint extractor 412, a file unit fingerprint extractor 413, a fingerprint register 414 and an interface device 415.

At step 452, the interface device 415 may obtain the original sound from the broadcast video and sound 260 of FIG.

In step 454, the interface device 415 may send the received original sound to the real-time fingerprint extractor 412 as an audio signal. If the sound for which the fingerprint is to be extracted is generated in the sound source file 416, the file may be transmitted to the file-based fingerprint extractor.

In step 456, the real-time fingerprint extractor 412 may extract the fingerprint data from the original sound audio signal obtained via the interface device 415. [ The fingerprint data may be digitized data. The real-time fingerprint extractor 412 may use a parallel scheme, which is a way to reduce the impact on the operation of the broadcast system when extracting the fingerprint data from the original sound. The parallel scheme may mean that the original sound output of the broadcast system and the output to the real-time fingerprint extractor 412 do not affect each other. The real-time fingerprint extractor 412 may send the fingerprint data to the fingerprint register 414.

In the case where sound is generated in the sound source file 416, the file-based fingerprint extractor 413 can extract the fingerprint data from the file. The file-based fingerprint extractor 413 can extract fingerprints using an algorithm applied to the original sound. The file-by-file fingerprint extractor 413 may send the fingerprint data to the fingerprint register 414.

At step 458, when fingerprint data is sent from the real-time fingerprint extractor 412 to the fingerprint register 414, the fingerprint register 414 sends the detailed information of the content for the entered fingerprint to the schedule table synchronization manager 414 411). For example, the detailed information of the content may include a broadcast date of the content, a start time and an end time of the content, a content ID, a content name, a broadcast channel of the content,

At step 460, the schedule synchronization manager 411 may request and receive the content scheduling information and the content scheduling information from the transmission operating system 270. For example, the content organization information may include daily broadcast schedule management information, weekly broadcast schedule management information, updated broadcast schedule information, and the like.

At step 462, the schedule synchronization manager 411 may process the scheduling information of the content into the content detail information. The schedule synchronization manager 411 may transmit fingerprint data and detailed information requiring indexing among the detailed content information to the fingerprint register 414. [ For example, the detailed information may include a content ID and a current playback time of the content. Among the detailed contents information, information used for indexing may be content information.

At step 464, the fingerprint register 414 may receive content detail information from the schedule synchronization manager 411.
