The present invention relates to a device and a method for providing a real-time broadcast schedule table which can select a broadcast while checking an image.

With the recent spread of media and the improvement of the communication speed of the Internet, a number of terrestrial broadcast channels, radio broadcast channels, as well as multimedia contents provided by Internet operators have been provided as broadcast services through the Internet.

A representative service that emerged from this background is an Internet Protocol Television (IPTV) service based on the Internet Protocol.

IPTV service is not only a VOD service that provides Video On Demand (VOD) content and a real time broadcasting service provided by a terrestrial broadcasting provider, but also various additional services including game service, karaoke service, weather service, and fortune service. (Value Added Service: VAS).

In this case, the VOD service and the real-time broadcast service provide a broadcast schedule using an electronic program guide (EPG) including program information for a plurality of broadcast contents.

In particular, the VOD service provides a broadcasting schedule for each genre so that the user can access the desired broadcasting content according to the genre selection, and the real-time broadcasting service provides a broadcasting schedule for each time zone based on the time flow so that the user is organized in the current time zone. You can select a channel to watch.

However, since the EPG information provided by the IPTV service is simply text information, a broadcasting schedule using the same is inevitably monotonous. Therefore, the VOD service defines thumbnail images or still images in advance for each video content on demand, and provides thumbnail images or still images defined for each content when providing broadcast program guide information. In streaming, its implementation is not easy due to the nature of streaming.

Therefore, in the real-time broadcast service, viewers must select broadcast contents while viewing text-oriented broadcast schedules, and the inconvenience of selecting in the absence of vivid information about what type of each broadcast content and who is the character still remains. have.

The present invention has been made to solve the above problems, using the I-frame of the real-time broadcast stream provided by the broadcast content provider to extract the image of the broadcast content that is currently being broadcast and the extracted program image (EPG) It is an object of the present invention to provide an apparatus and method for providing a real-time broadcast schedule table by providing an image of a broadcast currently being broadcast in a real-time broadcast schedule to provide viewers with the convenience of content selection.

1 is a diagram illustrating a network configuration of an apparatus for providing a real-time broadcasting schedule according to the present invention.

The apparatus for providing real-time broadcasting schedule of the present invention is included in the IPTV server unit 100.

The IPTV server unit 100 includes an IPTV head-end unit 110 and a VOD providing unit 120.

IPTV head-end unit 110 program provider (PP) 210, terrestrial provider 220, IPTV content provider (CP) 230, data provider (DP) 240, etc. The broadcast content supplied from the broadcast content provider 200 and the electronic program guide (EPG) information for the broadcast content is transmitted to the user terminal 400 of the viewer.

IPTV head-end unit 110 is a user terminal of a plurality of subscribers (join) joined to the corresponding channel by multicasting the real-time broadcast content and its EPG information through the IP backbone network 300, subscriber network (not shown) ( 400).

Or, if there is a request for the desired real-time broadcast content or EPG information from the user terminal 400 of the subscriber joined to the corresponding channel, the IPTV headend unit 110 transmits the real-time broadcast content or EPG information to the IP backbone network 300. It transmits to the user terminal 400 using a unicast scheme.

The VOD provider 120 is a system for providing VOD content to the user terminal 400 of the subscriber. The VOD provider 120 may provide a service of a real time broadcast as a VOD service in association with the IPTV headend 110. This requires a process of converting real-time broadcast content into VOD content.

IP backbone network 300 is basically a premium network 310 for transmitting and receiving data from the IPTV headend 110 or the user terminal 400 using a unicast or multicast routing protocol, and L3 switch 320 ), And a subscriber switch 330 for transmitting and receiving data for each subscriber.

The user terminal 400 may be connected to the IP-based set-top box 410 and the set-top box 410 to use the TV receiver 420 displayed on the screen. Alternatively, the TV receiver 420 having a built-in IP-based set-top box, or a terminal of any one of a computer, a laptop, a tablet PC, and a personal portable terminal may be used. Recently, as the IPTV service is provided to mobile phones and smart phones, the user terminal 400 may be a mobile phone or a smart phone.

The user terminal 400 is connected to the IPTV headend 110 and the VOD provider 120 through the IP backbone network 300 to receive and provide broadcast content and EPG information about real-time broadcast and VOD broadcast. The received broadcast content or EPG information is displayed on the screen.

In particular, the user terminal 400 of the present invention receives a broadcast schedule for real-time broadcasting and VOD broadcasting, displays them on a screen, and selects and views desired broadcast contents while viewing the displayed broadcast schedule.

The configuration of the IPTV head end unit 110 for this is specifically as shown in FIG.

Referring to FIG. 2, the IPTV headend unit 110 may include a baseband processor 111, an encoder 112, a multiplexer 113, a data broadcast provider 114, an EPG provider 115, and a multi-channel. The image extractor 116 and the interest channel registerer 117 for each user are included.

In addition, the system may further include a reception restriction system for restricting reception for each subscriber, a billing processing system for processing billing for a paid service, a monitoring system for managing quality, and a subscriber management system for managing subscriber information.

The baseband processor 111 receives an MPEG-2 broadcast signal and an analog broadcast signal from an external broadcast content provider (200 in FIG. 1), converts the received broadcast signal into a SDI (Serial Digital Interface) signal, and synchronizes frames. It distributes video and audio signals of various broadcast channels. When inserting data such as subtitle data, advertisements, and logos of a broadcast, editing thereof is also possible.

Of course, the baseband processor 111 should be provided with a tuner (tuner) for receiving an analog broadcast signal.

The encoder 112 encodes the broadcast video signal and the audio signal received from the baseband processor 111 for each broadcast channel. Normal video signals are encoded using the H.264 protocol, and audio signals are encoded by MPEG-2.

The multiplexer 113 multiplexes data broadcasting data and program related information (PSI) together with the video signal and the audio signal compressed by the encoding unit 112, and transmits the multiplexed transport stream (TS). IP packetization.

Since the multiplexer 113 multiplexes a video signal and an audio signal being transmitted through the encoding unit 112 in each real time broadcast channel and transmits the same as a stream, broadcast content and EPG information for all real time broadcast channels are included.

The data broadcast system 114 provides the multiplexer 113 with related data about broadcast content transmitted from all real-time broadcast channels. To this end, the data broadcasting system 114 includes a data manager for managing data encoding, a PSI generator for generating program related information (PSI), an encoder for encoding data broadcasting data, data for broadcasting data and program related information (PSI), and the like. The multiplexing unit 113 may include a multiplexer manager for managing the multiplexing by transmitting to the multiplexing unit 113.

The EPG provider 115 stores and manages EPG information among data output from the multiplexer 113.

In addition, the EPG providing unit 115 provides a real-time broadcast schedule including the broadcast content provided by each real-time broadcast channel from the EPG information, the broadcast date and time information, and the image of the broadcast content.

In this case, the EPG provider 115 may include the final broadcast image in the real-time broadcast schedule when the broadcast image is updated for each real-time broadcast channel. Therefore, a broadcast image is provided in real time with respect to a channel currently being broadcast, and a last broadcast image, that is, a last stored broadcast image, is provided with respect to a channel that has already been broadcast.

In addition, the EPG provider 115 may receive an image already prepared for the broadcast channel after the current time from the multi-channel image extractor 116 and include it in the real-time broadcast schedule.

The multi-channel image extractor 116 extracts an I-frame from a transport stream TS encoded or multiplexed by the encoder 112 or the multiplexer 113 to obtain an image (hereinafter, referred to as a broadcast image) of a video signal. . The multi-channel image extractor 116 transmits the broadcast image to the EPG provider 115 to provide the broadcast image together with the EPG information.

The I-frame is one of the video signals, which is the most basic data constituting video information, and does not include motion, and thus has a level of information that can be perceived by humans. The I-frame is one of the data structures of the MPEG-2 format, and is not limited to the I-frame, and may be replaced if the B-frame or the P-frame includes information on the I-frame. In addition, if there is a main frame including information of a still image that does not include motion in a video signal of another format, the main frame may be used as an I-frame.

In this case, when extracting an I-frame from the encoder 112, the multi-channel image extractor 116 extracts a broadcast image by one real time broadcast channel. Therefore, to extract the broadcast image of another channel that is currently being broadcasted, it may be obtained by completing the image extraction process of the previous channel and then performing the image extraction process for the desired channel.

When extracting I-frames from the multiplexer 113, since the multiplexed transport stream includes video signals for a plurality of channels, the multi-channel image extractor 116 simultaneously extracts I-frames for a plurality of real-time broadcast channels. Can be extracted. By such a configuration, the multi-channel image extractor 116 may simultaneously extract broadcast images of other channels that are currently being broadcast.

In addition, the multi-channel image extractor 116 may extract an image for each I-frame from the transport stream of the encoder 112 or the multiplexer 113 and transmit the image to the EPG provider 115 or set a predetermined period. After extracting the image for the I-frame that is streamed after reaching the preset period, the extracted broadcast image may be transferred to the EPG provider 115. That is, it is possible to set whether to extract an image or a sparse image whenever an I-frame exists.

In addition, the multi-channel image extractor 116 extracts a broadcast image in advance for a real-time broadcast channel to be broadcast after the current time and provides it to the EPG provider 115 to broadcast the channel other than the channel currently being aired on the real-time broadcast schedule. It also provides a broadcast image for. In this case, the broadcast image of the channel to be broadcast may use posters, thumbnails, preview images, and the like.

If the interest channel is registered for each user, the interested channel registerer 117 informs the multi-channel image extractor 116 about the interested channel and requests to extract an image of the interest channel from the currently broadcasted live channel. do. It provides a service that continuously updates and displays images of channels registered as channels of interest.

As such, when the show function of the interested channel is set, the multi-channel image extractor 116 refers to the interested channel registered in the interested channel registerer 117 for each user, and the interested channel in the currently broadcasted channel. Extract the broadcast image for, and transfer the extracted broadcast image to the EPG provider 115.

Then, the EPG provider 115 may include the broadcast image of the channel of interest in the real-time broadcast schedule and provide it to the user terminal, or the EPG information and the broadcast image of the channel of interest in the user terminal separately from the real-time broadcast schedule. Can be provided.

Accordingly, as shown in FIGS. 3 to 5, the user terminal provides a screen for displaying an image of a broadcast currently being broadcast on the real-time broadcast schedule.

3 illustrates a real-time broadcast schedule according to a broadcast date and a broadcast time zone based on a real-time broadcast channel.

The horizontal tab of the schedule is a broadcast date, the vertical tab represents a broadcast time zone, and the table is organized by real-time broadcast channel. That is, one program table represents information about one channel. The broadcast date can be displayed weekly or monthly.

For example, FIG. 3 illustrates a real-time broadcasting schedule for 'channel 1', and channel 1 shows broadcast contents' title 1 ',' title 2 ', and' title 3 at 6 AM to 8:00 AM on the 00th Monday. ',' title 4 'will be aired, and' title 5 ',' title 6 'and' title 7 'will be aired on Tuesday.

If the current time is 7:00 am on Tuesday, the schedule displays the broadcast image for 'title 7' currently being broadcast. Alternatively, the broadcast image may be selectively displayed for the previously broadcasted content. For example, the broadcasting content 'title 7' that is currently broadcasting can be updated and displayed in real time, and the last stored broadcasting image can be displayed for the broadcasting contents 'title 5' and 'title 6' that were broadcast before 7 o'clock. Can be. Images for past broadcasts can only be displayed for today's date (Tuesday), and can be displayed weekly, including the previous day (Monday). Alternatively, the broadcast image produced in advance may be matched with the broadcast content to be broadcast after the current time.

4 is a schedule according to a real-time broadcast channel and a broadcast time zone based on a broadcast date (00/00/00/00/0 day of the week) instead of a channel standard.

The bold lines on the table indicate that the current time is 7:00.

Similar to the schedule of FIG. 3, the schedule of FIG. 4 also broadcasts the currently broadcast contents 'title 1', 'title 4', 'title 6', and 'title 9' based on the current time (7:00). The image can be displayed. Alternatively, the broadcast image may be displayed as the last stored image of the previously broadcast contents 'title 3' and 'title 8' based on the current time (7:00 00), and the current time (7:00 00) Subsequently, the broadcast contents 'title 2', 'title 5', 'title 7', and 'title 10' to be broadcasted may display a previously produced broadcast image.

As described above, in order to simultaneously display the broadcast image for the multi-channel currently being broadcast, the I-frame is extracted from the transport stream provided through the multiplexer 113 of FIG.

Next, referring to FIG. 5, FIG. 5 is a screen displaying a schedule for a broadcast channel currently being broadcast on an AV screen.

The AV screen may be a screen for playing VOD content or a screen for playing real-time broadcast content, and may be a menu screen of an IPTV service or an additional service screen.

When the AV screen is a screen for playing VOD content, a menu screen of an IPTV service, or an additional service screen, the real-time broadcast schedule is a schedule for a real-time broadcast channel currently being broadcast.

If the AV screen is a screen for reproducing real-time broadcast content, the real-time broadcast schedule is a schedule for other real-time broadcast channels other than the broadcast channel currently being played on the AV screen.

Alternatively, the real-time broadcast schedule may be a schedule of interest channels for each user.

Accordingly, the user can check the program schedule screen displayed as shown in FIGS. 3 to 5 and check the propensity of the channel and the broadcasting time point while checking the broadcast status of the multi-channel of the real-time broadcast as an image. This can reduce channel channeling failures.

In addition, when a user registers a personal interest channel, the user can check a broadcast image of the channel of interest on a schedule or a screen watching another broadcast, thereby enabling a customized service.

6 is a flowchart illustrating a method of providing a real-time broadcasting schedule according to the present invention.

In the method for providing a real-time broadcast schedule according to the present invention, the IPTV headend unit receives the real-time broadcast content for each channel and the EPG information for the real-time broadcast content by streaming from the broadcast content provider (S100).

Then, the received real-time broadcast content and EPG information for each channel are encoded, and the encoded information is multiplexed on all channels (S110).

Subsequently, the IPTV headend unit extracts an I-frame from a transport stream (called a broadcast stream) that is encoded or multiplexed and output by the multi-channel image extractor to extract a real-time broadcast image of the broadcast content currently being broadcast (S120). ).

When extracting an I-frame from an encoded transport stream, the multi-channel image extractor extracts an image for one real time broadcast channel. Therefore, it is preferable to apply the multi-channel image extraction unit to extract a broadcast image for one or a small number of channels.

For example, when a user views a real-time broadcasting schedule and requests a image for broadcast content, or when an image of the channel of interest is selectively needed for the user's interest channel.

In addition, when extracting I-frames from the multiplexed transport stream, the multi-channel image extractor may simultaneously extract images for a plurality of real-time broadcast panels. Therefore, the multi-channel image extractor can extract even broadcast images of other channels that are currently being broadcast.

Thereafter, the IPTV headend unit delivers the image extracted by the multi-channel image extraction unit to the EPG provider to match the EPG information to provide a real-time broadcasting schedule table (S130).

In this case, whenever the I-frame is extracted, the corresponding image may be transmitted to the EPG provider to be updated in the real-time broadcast schedule (S140).

I-frame extraction can extract all I-frames present in the transport stream, but in order to reduce the load of the IPTV headend, a certain period is set and the I-frames existing after the set period are extracted or I-frames can be sequenced and selectively extracted according to the sequence.

Thereafter, the IPTV headend unit provides the real-time broadcasting schedule to the user terminal using a multicast or unicast scheme through the IP backbone network (S150).

The IPTV headend unit may provide the data of the real-time broadcast schedule including the broadcast image when provided to the user terminal, but the EPG information corresponding to the real-time broadcast schedule is provided according to the conventional method using multicast, and the broadcast image is the EPG information. Apart from the multicast, the multicast may be transmitted to the user terminal or may be transmitted in unicast upon request of the user terminal.

Accordingly, the user terminal displays a programming table including the real-time broadcast image of the broadcast currently being broadcast on the screen using the EPG information and the broadcast image received from the IPTV headend unit.

In addition, a process of providing a broadcast image corresponding to the interest channel for each user will be described with reference to FIG. 7.

The IPTV headend unit checks whether a broadcast image providing function for a channel of interest is set for each user (S200).

If it is set, the IPTV headend unit checks whether an interest channel for each user is registered (S210).

If the check result is not registered, the IPTV headend unit requests to register the interest channel to the user terminal and receives the information on the interest channel by the request and registers it (S220).

If the interest channel is already registered or registered through the registration process (S220), the broadcast image is extracted for the interest channel for each user registered in the currently broadcasting channel (S230). The extraction process is the same as a series of processes for extracting I-frames from the encoded or multiplexed transport stream in FIG.

Thereafter, the IPTV headend unit matches the extracted broadcast image of the channel of interest with the EPG and provides the corresponding user terminal with EPG information of the channel of interest including the broadcast image (S240 and S250).

In this case, the broadcast image and the EPG information of the channel of interest may be displayed together with the general real-time broadcasting schedule or may be separately displayed.

In addition, the broadcast image and the EPG information of the channel of interest can be displayed superimposed on the AV screen currently being viewed.

In step S250 of providing the last user terminal, a detailed transmission method is the same as mentioned in step S150 of FIG.

The foregoing description is merely illustrative of the present invention, and various modifications may be made by those skilled in the art without departing from the spirit of the present invention. Accordingly, the embodiments disclosed in the specification of the present invention are not intended to limit the present invention. The scope of the present invention should be construed according to the following claims, and all the techniques within the scope of equivalents should be construed as being included in the scope of the present invention.
