Embodiment 1 FIG.
FIG. 1 is a diagram showing an overall configuration of the present embodiment. FIG. 2 is a block diagram showing a configuration of program receiving system 100 according to the present embodiment.

  The program receiving system 100 includes a television 101 and a mobile terminal 102.

  The television 101 is an example of a first program receiving device and includes a receiving unit 110. The television 101 further includes a display unit 120.

  The receiving unit 110 is composed of, for example, a tuner connected to an external antenna. The receiving unit 110 receives a program being broadcast (for example, a baseball broadcast) from the program broadcasting system 200.

  The display unit 120 includes, for example, a light source, a liquid crystal panel, and the like. The display unit 120 displays the video of the program being received by the receiving unit 110.

  The mobile terminal 102 is an example of a second program receiving apparatus, and includes a receiving unit 130 and a detecting unit 140 and a control unit 150 in addition to the television 101. The mobile terminal 102 further includes an imaging unit 160 and a display unit 170.

  The receiving unit 130 includes, for example, an antenna, a tuner, a communication module, and the like. The receiving unit 130 receives a program being broadcast from the program broadcasting system 200, similarly to the receiving unit 110 of the television 101.

  The detection unit 140 and the control unit 150 are configured by a computer, for example. The computer includes hardware devices such as a processor and a memory. The processor executes a program in which functions such as the detection unit 140 and the control unit 150 are implemented. The memory stores the program and data used by the program. Operations of the detection unit 140 and the control unit 150 will be described later.

  The imaging unit 160 is configured with a camera, for example. The operation of the imaging unit 160 will be described later.

  The display unit 170 is constituted by a light source, a liquid crystal panel, or the like, for example. Similar to the display unit 120 of the television 101, the display unit 170 displays the video of the program being received by the reception unit 130.

  The program broadcasting system 200 includes a terrestrial digital broadcasting facility 201, a multimedia broadcasting facility 202, and a streaming distribution facility 203.

  The terrestrial digital broadcasting facility 201 includes a program transmission device 210 and a digital watermark embedding device 220.

  The program sending device 210 transmits a program X (for example, baseball) on channel A1 of digital terrestrial television broadcasting (an example of a broadcasting system) via the antenna system 300 from time T1 (for example, 18:00) to time T2 (for example, 21:00). Broadcast from the start to the middle of the game).

  In addition, the program sending device 210 transmits a program Ya (which is a continuation of the program X on the channel A2 of digital terrestrial television broadcasting via the antenna system 300 from time T2 to time T3 (for example, at 22:00 or at the end of a baseball game). For example, a broadcast from the middle to the end of a baseball game is broadcast.

  In addition, the program transmission device 210 transmits a program Yb (for example, a continuation of the program X on the channel B1 of the one-segment broadcasting (an example of a broadcasting system) from the time T2 to the time T3 in the same time zone as the program Ya via the antenna system 300. , Broadcast from the middle of the baseball game to the end).

  Note that the program sending device 210 broadcasts various programs on channels A1 and A2 for digital terrestrial television broadcasting, channel B1 for one-segment broadcasting, and the like at times other than the above.

  The digital watermark embedding device 220 generates information indicating that the program Ya is a continuation of the program X and is broadcast on the digital terrestrial television broadcast channel A2 from time T2 to time T3, as information on the program Ya. Then, the digital watermark embedding device 220 embeds information on the program Ya (an example of program continuation information) in advance in the video of the program X as a digital watermark. Therefore, the information of the program Ya is embedded in the video of the program X broadcast by the program transmission device 210.

  Further, the digital watermark embedding apparatus 220 generates information indicating that the program Yb is a continuation of the program X and is broadcast on the one-segment broadcasting channel B1 from time T2 to time T3, as the information of the program Yb. The digital watermark embedding device 220 embeds information of the program Yb (an example of program continuation information) in advance in the video of the program X as a digital watermark. Therefore, in the video of the program X broadcasted by the program transmission device 210, not only the information of the program Ya but also the information of the program Yb is embedded.

  The multimedia broadcast facility 202 includes a program transmission device 230 and a channel selection server 240.

  The program sending device 230 is a continuation of the program X on the channel C1 of multimedia broadcasting (an example of a broadcasting system) from the time T2 to the time T3, which is the same time zone as the programs Ya and Yb described above, via the antenna system 300. Broadcast Yc (for example, relay from the middle to the end of the baseball game). The program sending device 230 shows information indicating that the program Yc is a continuation of the program X and is broadcast on the multimedia broadcast channel C1 from the time T2 to the time T3 as the information of the program Yc before the time T2 at the latest. Is generated. Then, the program transmission device 230 transmits information about the program Yc to the digital watermark embedding device 220 of the terrestrial digital broadcasting facility 201. The digital watermark embedding device 220 receives the information of the program Yc, changes the format or the like as necessary, and then embeds the information of the program Yc (an example of program continuation information) in the video of the program X as a digital watermark in advance. . Therefore, in the video of the program X broadcasted by the program transmission device 210 of the terrestrial digital broadcasting facility 201, not only the information of the programs Ya and Yb but also the information of the program Yc is embedded.

  Note that the program transmission device 230 broadcasts various programs on a multimedia broadcast channel C1 and the like even in a time zone other than the above.

  The program Yc broadcast by the program transmission device 230 is scrambled. When the channel selection server 240 receives a channel selection request from the mobile terminal 102 via the mobile communication network 400, the channel selection server 240 authenticates the mobile terminal 102. Then, the channel selection server 240 transmits a descrambling key for channel C1 (or an individual descrambling key for program Yc) to mobile terminal 102 that has been successfully authenticated via mobile communication network 400.

  The streaming distribution facility 203 includes a distribution server 250.

  The distribution server 250 receives access to a predetermined URL from the mobile terminal 102 via the Internet 500 and the mobile communication network 400. Distribution server 250 accepts access to the URL from terminals other than portable terminal 102 via Internet 500. Then, the distribution server 250 performs Internet broadcasting, that is, streaming distribution (from the time T1 to time T3) via the Internet 500 (and the mobile communication network 400) to each terminal (after performing authentication as necessary). The program X including the program X and the continuation thereof (for example, relay from the start to the end of the baseball game) is broadcast by an example of a broadcasting system. The distribution server 250 generates information indicating that the program Z includes the continuation of the program X and is broadcast at the URL from time T1 to time T3 as the information of the program Z at the latest before the time T2. Then, the distribution server 250 transmits information on the program Z to the digital watermark embedding device 220 of the terrestrial digital broadcasting facility 201. The digital watermark embedding device 220 receives the information of the program Z, changes the format or the like as necessary, and embeds the information of the program Z (an example of program continuation information) in advance in the video of the program X as a digital watermark. . Therefore, in the video of the program X broadcast by the program transmission device 210 of the terrestrial digital broadcasting facility 201, not only the information of the programs Ya, Yb, Yc but also the information of the program Z is embedded.

  Note that the distribution server 250 performs streaming distribution (that is, broadcast) of various programs using the URL or the like in other time zones.

  Here, the digital watermark embedding device 220 of the digital terrestrial broadcasting facility 201 may embed the program continuation information in the video of the program X over the entire broadcast time of the program X, or the program continuation information may be part of the broadcast time of the program X ( For example, it may be embedded in the video of the program X only for a few minutes (just before the end of the broadcast of the program X). Also, the digital watermark embedding device 220 may embed the program continuation information in the video of the program X in a format that can be received by visible light communication instead of embedding the program continuation information in the video of the program X as a digital watermark.

  When the program continuation information is embedded in the video of the broadcast program, the program transmission device 210 of the terrestrial digital broadcasting facility 201 indicates that the program continuation information is embedded (or regardless of the type or content of the information). It is desirable to put characters, symbols, etc. (indicating that a digital watermark is embedded) on the video of the program. At this time, the program sending apparatus 210 may put the characters, symbols, etc. on the video of the program over the entire time in which the digital watermark of the program is embedded. It is preferable to put it on the video of the program only for a few minutes immediately before the end). Note that it may be notified by voice that the program continuation information is embedded in the program.

  FIG. 3 is a flowchart showing the operation of the program receiving system 100 (program receiving method according to the present embodiment, processing procedure of the program according to the present embodiment).

  As described above, from time T1 to time T2, program X is broadcast on channel A1 of terrestrial digital television broadcasting. Here, it is assumed that the user selects the channel A1 for terrestrial digital television broadcasting by operating a remote controller (not shown) of the television 101 or the like in order to view the program X.

  In step S101, the receiving unit 110 of the television 101 receives the program X being broadcast on the digital terrestrial television broadcast channel A1 from the program transmission device 210 of the terrestrial digital broadcast facility 201 of the program broadcast system 200 via the antenna system 300. . The display unit 120 of the television 101 displays the video of the program X being received by the receiving unit 110 of the television 101. Thereby, the user can view the program X on the display unit 120 of the television 101.

  As described above, in the video of the program X, information on the programs Ya, Yb, Yc, which is a continuation of the program X, and information on the program Z including the continuation of the program X are embedded as digital watermarks. Here, it is assumed that the user points the photographing unit 160 of the mobile terminal 102 toward the display unit 120 of the television 101 in order to read the digital watermark.

  In step S <b> 102, the imaging unit 160 of the mobile terminal 102 captures an image being displayed on the display unit 120 of the television 101. The detection unit 140 of the mobile terminal 102 detects and decodes a digital watermark from the video imaged by the imaging unit 160 of the mobile terminal 102, and obtains information on the programs Ya, Yb, Yc, and Z. That is, the detection unit 140 of the mobile terminal 102 detects information embedded as a digital watermark in the video of the program X being received by the reception unit 110 of the television 101. The display unit 170 of the mobile terminal 102 displays a screen for selecting the programs Ya, Yb, Yc, Z together with information on the programs Ya, Yb, Yc, Z detected by the detection unit 140 of the mobile terminal 102. Note that the display unit 170 of the mobile terminal 102 may display information such as the presence / absence of a contract necessary for viewing each program and the image quality of each program as an index when selecting the programs Ya, Yb, Yc, and Z. . The display unit 170 of the portable terminal 102 may further display whether each program can be selected, the priority order, and the like according to the index and the length of the broadcast time of each program. The information serving as an index may be included in the program continuation information, or may be determined in advance for each program broadcasting system or channel.

  As described above, from time T2 to time T3, the program Ya is broadcast on the digital terrestrial television broadcast channel A2, the program Yb is broadcast on the one-segment broadcast channel B1, and the program Yc is broadcast on the multimedia broadcast channel C1. Yes. In addition, from time T1 to time T3, the program Z is distributed by streaming at a predetermined URL. Here, in order to view the program Yb after the broadcast of the program X, the user selects the program Yb on the screen by operating the touch panel (display unit 170) or a button (not shown) of the mobile terminal 102. Suppose.

  In step S103, the control unit 150 of the mobile terminal 102 causes the reception unit 130 of the mobile terminal 102 to receive the program Yb after time T2, based on the information of the program Yb detected by the detection unit 140 of the mobile terminal 102. to decide. Then, the control unit 150 of the mobile terminal 102 controls the reception unit 130 of the mobile terminal 102 to start receiving the program Yb on the one-segment broadcasting channel B1 at time T2 or immediately before (for example, one minute before). . The receiving unit 130 of the portable terminal 102 receives the program Yb being broadcast on the one-segment broadcasting channel B1 from the program sending device 210 of the terrestrial digital broadcasting facility 201 of the program broadcasting system 200 via the antenna system 300. The display unit 170 of the mobile terminal 102 displays the video of the program Yb being received by the receiving unit 130 of the mobile terminal 102. Thus, the user can view the continuation of the program X after the broadcast of the program X is completed with a simple operation. For example, a troublesome operation of selecting the one-segment broadcasting channel B1 on the mobile terminal 102 at time T2 or just before that time becomes unnecessary. Note that the control unit 150 of the mobile terminal 102 may control the reception unit 130 of the mobile terminal 102 to end the reception of the program Yb at or after the time T3 (for example, one minute later).

  Here, after step S102, it is assumed that the user selects the program Yc on the screen by operating the touch panel, buttons, and the like of the mobile terminal 102 in order to view the program Yc after the broadcast of the program X ends.

  In step S103, the control unit 150 of the mobile terminal 102 causes the reception unit 130 of the mobile terminal 102 to receive the program Yc after time T2 based on the information of the program Yc detected by the detection unit 140 of the mobile terminal 102. to decide. In addition, the control unit 150 of the mobile terminal 102 transmits a channel C1 channel selection request to the channel selection server 240 of the multimedia broadcast facility 202 of the program broadcast system 200 via the mobile communication network 400, and scrambles the channel C1. Obtain a key for release. Then, the control unit 150 of the mobile terminal 102 controls the reception unit 130 of the mobile terminal 102 to start receiving the program Yc on the multimedia broadcast channel C1 at or before time T2 (for example, 1 minute before). To do. The receiving unit 130 of the portable terminal 102 receives the program Yc being broadcast on the multimedia broadcast channel C1 from the program sending device 230 of the multimedia broadcasting facility 202 of the program broadcasting system 200 via the antenna system 300. The program Yc is unscrambled using the key acquired by the control unit 150. The display unit 170 of the mobile terminal 102 displays the video of the program Yc that is being received (after descrambling) by the receiving unit 130 of the mobile terminal 102. Thus, the user can view the continuation of the program X after the broadcast of the program X is completed with a simple operation. For example, a troublesome operation such as selecting the multimedia broadcast channel C1 on the portable terminal 102 at the time T2 or just before the time T2 becomes unnecessary. Note that the control unit 150 of the mobile terminal 102 may control the reception unit 130 of the mobile terminal 102 to end the reception of the program Yc at or after time T3 (for example, one minute later).

  Here, after step S102, in order for the user to view the program Z after the broadcast of the program X ends (or from the middle of the broadcast of the program X), the user operates the touch panel or button of the portable terminal 102 to display the program on the screen. Suppose that Z is selected.

  In step S103, the control unit 150 of the portable terminal 102 carries the program Z after the time T2 (or any time before the time T2) based on the information of the program Z detected by the detection unit 140 of the portable terminal 102. It is determined that the reception unit 130 of the terminal 102 receives the data. Then, the control unit 150 of the mobile terminal 102 controls the receiving unit 130 of the mobile terminal 102 to access a predetermined URL and start receiving the program Z at time T2 or immediately before (for example, 1 minute before). To do. The receiving unit 130 of the portable terminal 102 receives the program Z being stream-distributed with a predetermined URL from the distribution server 250 of the streaming distribution facility 203 of the program broadcasting system 200 via the Internet 500 and the mobile communication network 400. The display unit 170 of the mobile terminal 102 displays the video of the program Z being received by the receiving unit 130 of the mobile terminal 102. Thus, the user can view the continuation of the program X after the broadcast of the program X is completed with a simple operation. For example, a troublesome operation of inputting a predetermined URL at the portable terminal 102 at time T2 or just before it becomes unnecessary. Note that the control unit 150 of the mobile terminal 102 may control the reception unit 130 of the mobile terminal 102 to end the reception of the program Z at or after the time T3 (for example, one minute later).

  As described above, in the present embodiment, the program broadcast system 200 embeds guidance data for related content with digital watermark in the digital broadcast content. The program receiving system 100 uses the camera included in the mobile terminal 102 to re-capture the screen of the television 101, and extracts watermark data from the screen in a short time (for example, several seconds). The program receiving system 100 selects a broadcast or streaming content distributed to the mobile terminal 102 from the extracted guidance data.

  In the conventional device cooperation technology, control data called metadata is required to be generated and used in accordance with a standard by all components of a broadcasting station and a receiver. For example, it is convenient if you can watch the continuation of sports broadcasts on channels such as 1Seg broadcasting after the broadcast of sports broadcasts on digital terrestrial television broadcast channels ends, but large-scale development and changes are necessary to use conventional technology. Because it is necessary, it is difficult to realize. According to the present embodiment, by using the digital watermark technology, it can be realized at a low cost with almost no influence on the existing facilities and methods.

  In the present embodiment, program broadcast system 200 further includes a facility for broadcasting a program on a satellite broadcast (an example of a broadcast system) channel via a satellite (not shown), a CATV network (not shown). ) Through a cable television broadcast (an example of a broadcasting system). These facilities include devices similar to the program transmission device 210 and digital watermark embedding device 220 of the terrestrial digital broadcasting facility 201, devices similar to the program transmission device 230 of the multimedia broadcasting facility 202, or both devices. And Programs broadcast by satellite broadcasting and cable television broadcasting can be handled in the same manner as the programs broadcast by terrestrial digital television broadcasting, one-segment broadcasting, multimedia broadcasting, and streaming distribution. Therefore, the user can view the continuation of the program by satellite broadcasting or cable television broadcasting after the completion of broadcasting of the program viewed by digital terrestrial television broadcasting with a simple operation. Alternatively, the user can view the continuation of the program by one-segment broadcasting or the like after the broadcast of the program viewed by satellite broadcasting or cable television broadcasting is completed with a simple operation.
