(Step S9).
Then, the content transmitting apparatus 100 transmits the stream received from the multiplexing unit 111 by the transmitting unit 112 to a plurality of content receiving apparatuses 200 (see FIG. 6) via a transmission antenna (not shown) (Step S10). ).

[Operation of content receiver]
Next, the operation of the content receiving apparatus will be described with reference to FIGS. 9 and 10 and FIGS. 6 and 7 as appropriate. FIG. 9 is a flowchart showing the operation (part 1) of the content receiving apparatus according to the present embodiment. FIG. 10 is a flowchart showing the operation (part 2) of the content receiving apparatus according to the present embodiment.
As shown in FIG. 9, the content receiving apparatus 200 receives a stream by the receiving unit 201 (step S21) and outputs the stream to the separating unit 202. Then, the content receiving apparatus 200 separates the stream received from the receiving unit 201 into the content 101a, the PSI or SI, the EMM common message, and the EMM individual message by the separating unit 202 (step S22). . Further, the content receiving apparatus 200 outputs the content 101 a separated from the stream by the separating unit 202 to the video composition unit 214. Also, the PSI or SI including the separated electronic program guide information 102 a is output to the electronic program guide information configuring unit 203. In addition, an EMM common message including the advertisement information 104a and the display control information 120 separated from the stream is output to the advertisement information extraction unit 204 and the display control information extraction unit 206, respectively. Further, the separating unit 202 outputs the EMM individual message including the contract information 105 a separated from the stream, the content receiving device ID 106 a, and the content receiving device ID comparing unit 207.

In the content receiving apparatus 200, the electronic program guide information configuring unit 203 configures the electronic program guide information from the PSI or SI received from the separating unit 202 (step S23). The content receiving apparatus 200 outputs the configured electronic program guide information to the video composition unit 214 by the electronic program guide information configuring unit 203.
In addition, the content receiving apparatus 200 extracts a plurality of pieces of advertisement information 104a from the EMM common message received from the separation unit 202 by the advertisement information extraction unit 204, and stores it in the advertisement information storage unit 205 (step S24).

Further, the content receiving apparatus 200 extracts the display control information 120 from the EMM common message received from the separating unit 202 by the display control information extracting unit 206 and outputs the extracted information to the message ID comparing unit 211 and the display control unit 213, respectively. (Step S25).
In addition, the content receiving device 200 acquires the content receiving device ID 106a from the EMM individual message received from the separating unit 202 by the content receiving device ID comparing unit 207, and from the content receiving device ID storage unit 209 to the own device. The unique content receiving device ID 209a is acquired (step S26), and it is determined whether or not the content receiving device ID 106a matches the unique content receiving device ID 209a (step S27).

  If the content receiving device ID comparing unit 207 determines that the content receiving device ID 106a and the unique content receiving device ID 209a match (Yes in step S28), the content receiving device 200 sends the EMM to the contract information extracting unit 208. Output individual messages. Then, the content receiving apparatus 200 extracts the contract information 105a from the EMM individual message by the contract information extraction unit 208 and stores it in the contract information storage unit 210 (step S29). In addition, the content receiving apparatus 200 notifies the message ID comparing unit 211 that the contract information 105a has been extracted by the contract information extracting unit 208. On the other hand, when the content receiving device ID comparison unit 207 determines that the content receiving device ID 106a and the unique content receiving device ID 209a do not match (No in step S28), the determination result is output to the display control unit 213. Then, the display control means 213 (combination instruction means 213a) instructs the video composition means 214 to set the video information as the main line video (step S43 in FIG. 10).

  Subsequent to step S29, when the content receiving apparatus 200 accepts an input of the notification “contract information 105a has been extracted” from the contract information extracting unit 208 by the message ID comparing unit, the contract stored in the contract information storing unit 210 is received. The second message ID 105b included in the information 105a is acquired. Further, the first message ID 120c is acquired from the display control information 120 extracted in step S25 (step S30). Then, the content receiving apparatus 200 uses the message ID comparison unit 211 to receive the first message ID 120c included in the display control information 120 received from the display control information extraction unit 206, and the second acquired from the contract information storage unit 210. Are compared to determine whether the first message ID 120c matches the second message ID 105b (step S31).

  When the message ID comparison unit 211 determines that the first message ID 120c and the second message ID 105b match (Yes in step S32), the content reception device 200 compares the display control information 120 with the reception device group designation information comparison. It outputs to the means 212 (step S33). On the other hand, when the message ID comparison unit 211 determines that the first message ID 120c and the second message ID 105b do not match (No in step S32), the determination result is output to the combination instruction unit 213a. When the composition instruction unit 213a receives an input of a determination result “the first message ID 120c and the second message ID 105b do not match” from the message ID comparison unit 211, the content reception device 200 receives the video composition unit 214. The instruction “Do not synthesize the video information of the content 101a and the advertisement information 104a” is issued (step S43 in FIG. 10). When the content synthesizing unit 214 receives an input from the compositing instruction unit 213a that “the video information of the content 101a and the advertising information 104a are not combined” by the video compositing unit 214, the content receiving device 200 sets the video information of the content 101a as a main video. The main line video is output to an external display means 400 (see FIG. 1), for example (step S44 in FIG. 10).

  Subsequent to step S33, when the content receiving apparatus 200 receives input of the display control information 120 from the message ID comparing means 211 by the receiving apparatus group designation information comparing means 212, the content receiving apparatus 200 stores the content receiving apparatus 200 from the content receiving apparatus ID storage means 209 to its own apparatus. The unique content receiving device ID 209a is acquired (step S34). The content receiving device 200 receives the partial data of the unique content receiving device ID 209a acquired from the content receiving device ID storage unit 209 by the receiving device group designation information comparison unit 212 and the display control that receives the input from the display control information extraction unit 206. The receiving device group designation information 120a included in the information 120 is compared with the matching data length 120b included in the display control information 120 (step S35), and it is determined whether or not they match.

  In the content receiving device 200, when the receiving device group designation information comparing unit 212 matches the partial data of the content receiving device ID 106a and the receiving device group designation information 120a (the own device belongs to the group displaying the advertisement information 104a). If it is determined (Yes in step S36), the determination result is output to the composition instruction means 213a (step S37).

The content receiving device 200 receives an input of a determination result “the partial data of the content receiving device ID 106a and the receiving device group specifying information 120a match” from the receiving device group specifying information comparing unit 212 by the composition instructing unit 213a. In this case, the genre ID comparison unit 213e acquires the genre ID 101i initially set in the content receiving device 200 and the plurality of genre IDs 120i included in the display control information 120 (step S38).
Then, the content receiving apparatus 200 compares the genre ID 101i with the plurality of genre IDs 120i by the genre ID comparison unit 213e, and whether or not there is a genre ID 120i that matches the genre ID 101i in the plurality of genre IDs 120i. Is determined (step S39).

  When the genre ID comparison unit 213e determines that the genre ID 120i is the same as the genre ID 101i by the genre ID comparison unit 213e (Yes in step S40), the content reception device 200 displays the determination result as the combination instruction unit 213a. Output to. On the other hand, when the genre ID comparison unit 213e determines that there is no genre ID 120i that matches the genre ID 101i (No in step S40), the content reception device 200 outputs the determination result to the composition instruction unit 213a. When the composition instruction unit 213a receives from the genre ID comparison unit 213e an input of a determination result “a genre ID 120i that matches the genre ID 101i is present among the plurality of genre IDs 120i”, the content reception device 200 performs video composition. Information for identifying the advertisement information 104a assigned the genre ID 120i that matches the genre ID 101i is output to the means 214 (step S41).

For example, when the genre ID of the default content is “A”, the genre ID comparison unit 213e causes a plurality of pieces of advertisement information 104a (advertisement information A (advertisement A) to advertisement information D (advertisement D)) (see FIG. 5). ), It is determined that the advertisement information A (advertisement A), which is the advertisement information 104a to which “A” is assigned as the genre ID 120i, matches the advertisement information D (advertisement D). Then, the content receiving apparatus 200 outputs information identifying the advertisement information A and information identifying the advertisement information D to the video composition unit 214 by the composition instruction unit 213a.
Note that the compositing instruction unit 213a designates the size of the advertisement video, and instructs the video compositing unit 214 to synthesize the main video with the specified size. Here, the compositing instruction unit 213a designates the size of the advertisement video by designating any numerical value within a range of 15% or more and 70% or less as a range in which the advertisement video hides the main line video. Further, the compositing instruction unit 213a notifies the display time information 120f and the display position information 120g of the advertisement video together. Further, the compositing instruction unit 213a instructs the video compositing unit 214 how to display the advertisement video. For example, an instruction is given to display the advertisement video in two.
When the content receiving apparatus 200 receives input of information for identifying the advertisement information A and information for identifying the advertisement information D from the composition instruction unit 213a by the video composition unit 214,
The video information included in the content 101a is the main video, the advertising information A and the advertising information D are the advertising video, the main video is the background, the advertising video is the foreground, and the advertising video of the advertising information A is superimposed on a part of the main video. In addition, the advertisement video of the advertisement information D is superimposed on a part of the main line video and synthesized (step S45). Then, the content receiving apparatus 200 sequentially outputs the synthesized video by the video synthesizing unit 214 to an external display unit 400 (see FIG. 1), for example. The order of output is not particularly limited.

  On the other hand, when the content receiving apparatus 200 receives an input of a determination result “no genre ID 120i matching the genre ID 101i is present in the plurality of genre IDs 120i” from the genre ID comparison unit 213e by the composition instruction unit 213a. Information for identifying the default advertisement information 104a is output to the video composition unit 214 (step S42). Note that the compositing instruction unit 213a designates the size of the advertisement video, and instructs the video compositing unit 214 to synthesize the main video with the specified size. Here, the composition instruction means 213a designates the size of the advertisement video by designating any numerical value within a range of 15% or more and 70% or less as a range in which the advertisement video hides the main line video. Further, the compositing instruction unit 213a notifies the display time information 120f and the display position information 120g of the advertisement video together. Further, the compositing instruction unit 213a instructs the video compositing unit 214 how to display the advertisement video. For example, an instruction is given to display the advertisement video in two.

  When the content receiving apparatus 200 receives input of information for identifying the default advertising information 104a from the compositing instruction unit 213a by the video compositing unit 214, the content receiving device 200 sets the video information as the main video and the default advertising information 104a as the advertising video. Then, using the main video as the background and the default advertising video as the foreground, the default advertising video is superimposed on a part of the main video and synthesized (step S46). Then, the content receiving apparatus 200 outputs the synthesized video to the outside, for example, the display unit 400 (see FIG. 1) by the video synthesizing unit 214.

  On the other hand, when the content receiving device 200 determines that the partial data of the content receiving device ID 106a does not match the receiving device group specifying information 120a by the receiving device group specifying information comparing unit 212 based on the determination in step S36 (step S36). No), the determination result is output to the synthesis instruction means 213a. The content receiving apparatus 200 instructs the video composition unit 214 not to synthesize the video information and the advertisement information 104a by the composition instruction unit 213a (step S43). Then, the content receiving apparatus 200 sets the video information to the main video by the video synthesizing unit 214 (step S44).

  Next, when the content receiving apparatus 200 receives an input of an erasure request for the advertisement video via the input unit 300 from a user who has viewed a video in which a part of the main line video is hidden by the advertisement video, the content reception is performed. The operation of the apparatus 200 will be described.
