Next, based on the control identification information and the time information, it is determined whether the instruction is a recording start instruction or a recording end instruction, and the time is determined. If it is an instruction to start recording, the video / audio stream is stored in the storage unit 25 from the frame indicated by the time code of the time information. On the other hand, if it is an instruction to end the recording, the storage of the video / audio stream in the storage unit 25 is stopped at the frame indicated by the time code of the time information.
[0032]
Next, the operation of the first embodiment will be described using a specific example.
[0033]
FIG. 5 is an operation flowchart of the first embodiment, and FIG. 6 is a diagram for explaining the operation.
[0034]
First, recording start control will be described.
In the description of this operation, a baseball broadcast program is taken as an example of the video / audio stream, and the recording target identification information of this video / audio stream is assumed to be “100”. Further, the description will be made assuming that “aaa” is the identification information for identifying the recording controller, “1” is the recording start instruction as the control identification information, and “0” is the recording end instruction. Also, a time code attached to the video is used as the start of recording or the end of recording. Further, it is assumed that “100” is attached to the video / audio stream as identification information for identifying a program.
[0035]
As shown in FIG. 6, the broadcast station 1 broadcasts a video / audio stream of a baseball broadcast program, and, for example, a recording controller that causes the receiver 2 to record a highlight scene A is recorded by the recording controller generator 10. Generate.
[0036]
First, the recording controller generation unit 10 records “aaa” as identification information indicating that it is a recording controller, and “100” indicating that it is a baseball broadcast program as recording identification information as control identification information. A recording controller is generated by assigning “1” indicating the start instruction of “19” and “19:30:30” as the start of recording (Step 100).
[0037]
Subsequently, the encoded video / audio stream and the recording controller generated by the recording controller generator 10 are multiplexed by the multiplexing unit 11 (Step 101) and transmitted from the transmission facility 12 (Step 102). .
[0038]
In the receiver 2, the video / audio stream is received by the reception unit 20 (Step 103), and the controller and the video / audio stream are separated from the video / audio stream by the separation unit 21 (Step 104).
[0039]
Next, the recording control unit 25 determines whether the controller is a recording controller (Step 105). In this example, since the identification information is “aaa”, the controller is a recording controller.
[0040]
If the controller is a recording controller (Step 106), the video / audio stream to be recorded is identified based on the recording target identification information (Step 107). In this example, since the recording target identification information is “100”, the recording target is a video / audio stream of a baseball broadcast program.
[0041]
Subsequently, it is determined whether the instruction is a recording start instruction or a recording end instruction based on the control identification information (Step 108). In this example, since the control identification information is “1”, it is a recording start instruction.
[0042]
Based on the time information, the recording start time is determined (Step 109), and the recording is started (Step 110). In this example, since the time information is “19:30”, the recording is started from the frame whose time code is “19:30”. That is, the video / audio stream starts to be stored in the storage unit 24.
[0043]
In this way, the start of recording in the receiver 2 can be controlled.
[0044]
Next, recording end control will be described.
The identification information and the like are the same as those described above.
[0045]
As shown in FIG. 6, the broadcast station 1 broadcasts a video / audio stream of a baseball broadcast program, and, for example, a recording controller for generating a recording controller for ending recording in the receiver 2 of the highlight scene A. 10 is generated.
[0046]
First, the recording controller generator 10 controls and identifies “aaa” as identification information indicating that the controller is a recording controller, and “100” indicating that the controller is a baseball broadcast program in the recording target identification information. A recording controller is generated by assigning “0” indicating that it is an instruction to end recording as information and “19:31:00” as the end of recording (Step 100).
[0047]
Subsequently, the encoded video / audio stream and the recording controller generated by the recording controller generator 10 are multiplexed by the multiplexing unit 11 (Step 101) and transmitted from the transmission facility 12 (Step 102). .
[0048]
In the receiver 2, the video / audio stream is received by the reception unit 20 (Step 103), and the recording controller and the video / audio stream are separated from the video / audio stream by the separation unit 21 (Step 104).
[0049]
Next, the recording control unit 25 determines whether the controller is a recording controller (Step 105). In this example, since the identification information is “aaa”, the controller is a recording controller.
[0050]
If the controller is a recording controller (Step 106), the video / audio stream to be recorded is identified based on the recording target identification information (Step 107). In this example, since the recording target identification information is “100”, the recording target is a video / audio stream of a baseball broadcast program.
[0051]
Subsequently, based on the control identification information, it is determined whether it is an instruction to start recording or an instruction to end recording (Step 108). In this example, since the control identification information is “0”, it is an instruction to end recording.
[0052]
Then, based on the time information, the time is judged (Step 111), and the recording is ended (Step 112). In this example, since the time information is “19:31:00”, the recording ends at the frame where the time code is “19:31:00”. That is, the storage of the video / audio stream in the storage unit 24 is stopped.
In this way, the end of recording can be controlled from the broadcasting station side.
[0053]
A second embodiment will be described.
[0054]
In the first embodiment, recording of a receiver is controlled from the broadcasting station side, and a scene designated by the broadcasting station is recorded by the receiver. The video recorded in the receiver can also be viewed during a commercial broadcast in the middle of the program.
[0055]
However, it may not be preferable for a broadcast station to watch a video recorded during a commercial broadcast.
[0056]
Therefore, in the second embodiment, playback of recorded video / audio is also controlled from the broadcasting station side, and even recorded video is prohibited from being viewed when a commercial or the like is broadcast. It is characterized by that.
[0057]
In order to achieve the above characteristics, in the second embodiment, as shown in FIG. 7, the playback controller generation for generating the playback controller for controlling the playback of the video / audio recorded by the receiver 2 is performed. The unit 30 is newly provided in the broadcasting station 1. The playback controller generated by the playback controller generator 30 is configured in the same format as the recording controller described above, and information indicating that it is a playback controller is described in the identification information. The identification information of the program to be controlled for reproduction is described, and information indicating whether the instruction to start reproduction prohibition or the instruction to cancel reproduction prohibition is described as the control identification information. The start time of each instruction Is described as time information.
[0058]
Also, the generation timing of the playback controller by the playback controller generation unit 30 is the ON or OFF timing of the OA tally signal output from the switcher 13 that switches the broadcast video, similar to the generation timing of the recording controller. Done in For example, when the video to be broadcast is switched to commercial by the switcher 13 or when the scene is switched to normal broadcasting, the playback controller generation unit receives ON / OFF of the OA tally signal of the commercial. 10 generates a recording controller for controlling the reproduction of the recorded video.
[0059]
Furthermore, in the second embodiment, as shown in FIG. 8, a playback control unit 40 is newly provided in the receiver 2. The reproduction control unit 40 performs control for permitting or prohibiting reproduction of the video / audio stored in the storage unit 24 based on the reproduction controller transmitted from the broadcast station 1.
[0060]
Next, the operation of the second embodiment will be described.
FIG. 9 is an operation flowchart of the second embodiment, and FIG. 10 is a diagram for explaining the operation.
[0061]
First, playback start control is described.
[0062]
In the description of this operation, a baseball broadcast program is taken as an example of the video / audio stream recorded by the receiver 2, and the recording target identification information of this video / audio stream is assumed to be "100". In addition, it is assumed that the control element is “bbb” as identification information for identifying the reproduction controller, the reproduction prohibition start instruction is “1”, and the reproduction prohibition release instruction is “0” as control identification information. In addition, a time code attached to the video is used as the start of playback prohibition or the release of playback prohibition.
[0063]
Further, it is assumed that the highlight scene A of the video / audio stream of the baseball broadcast program described in the first embodiment is recorded in the receiver 2.
[0064]
In the broadcasting station 1, as shown in FIG. 10, a playback controller for generating a playback controller that prohibits playback of the highlight scene A recorded during the commercial broadcast after broadcasting a video / audio stream of a baseball broadcast program. Generate by.
[0065]
First, the reproduction controller generation unit 30 reproduces “bbb” as identification information indicating that it is a reproduction controller, and “100” indicating that it is a baseball broadcast program as control identification information as control identification information. A reproduction controller is generated by assigning “1” indicating an instruction to start prohibition to “19:31:01” as the start of reproduction prohibition (Step 200).
[0066]
Subsequently, the encoded video / audio stream and the reproduction controller generated by the reproduction controller generation unit 30 are multiplexed by the multiplexing unit 11 (Step 201) and transmitted from the transmission facility 12 (Step 202). .
[0067]
In the receiver 2, the video / audio stream is received by the reception unit 20 (Step 203), and the controller and the video / audio stream are separated from the video / audio stream by the separation unit 21 (Step 204).
[0068]
Next, the reproduction control unit 40 determines whether or not the controller is a reproduction controller (Step 205). In this example, since the identification information is “bbb”, the controller is a playback controller.
[0069]
If the controller is a playback controller (Step 206), the video / audio stream that is subject to playback prohibition is identified based on the recording target identification information (Step 207). In this example, since the recording target identification information is “100”, the reproduction prohibited recording target is a video / audio stream of a baseball broadcast program.
[0070]
Subsequently, based on the control identification information, it is determined whether the instruction is to start reproduction prohibition or to cancel reproduction prohibition (Step 208). In this example, since the control identification information is “1”, this is a reproduction prohibition start instruction.
[0071]
Then, based on the time information, the playback prohibition start time is determined (Step 209), and playback prohibition is started (Step 210). In this example, since the time information is “19:31:01”, the video / audio stream of the recorded baseball broadcast program from the frame whose time code is “19:31:01”, for example, the first implementation The prohibition of reproduction of the highlight scene A described in the form is started. In other words, the recorded highlight scene A cannot be reproduced by a user operation.
[0072]
In this way, it is possible to control the reproduction of the recorded scene on the receiver side 2.
[0073]
Next, the reproduction prohibition release control will be described.
[0074]
The identification information and the like are the same as those described above.
[0075]
As shown in FIG. 10, the broadcast station 1 broadcasts a video / audio stream of a baseball broadcast program, and, for example, a playback controller that cancels the prohibition of playback of a recorded highlight scene A. Generated by the generation unit 30.
[0076]
First, the reproduction controller generation unit 30 reproduces “bbb” as identification information indicating that it is a recording controller, and “100” indicating that it is a baseball broadcast program as recording identification information as control identification information. A recording controller is generated by assigning “0” indicating an instruction to cancel the prohibition and “19:33:00” when canceling the playback prohibition (Step 200).
[0077]
Subsequently, the encoded video / audio stream and the reproduction controller generated by the reproduction controller generation unit 30 are multiplexed by the multiplexing unit 11 (Step 201) and transmitted from the transmission facility 12 (Step 202). .
[0078]
In the receiver 2, the video / audio stream is received by the reception unit 20 (Step 203), and the controller and the video / audio stream are separated from the video / audio stream by the separation unit 21 (Step 204).
[0079]
Next, the playback control unit 31 determines whether the control is a playback control (Step 205). In this example, since the identification information is “bbb”, the controller is a playback controller.
[0080]
If the controller is a playback controller (Step 206), the video / audio stream that is subject to playback prohibition is identified based on the recording target identification information (Step 207). In this example, since the recording target identification information is “100”, the recording target is a video / audio stream of a baseball broadcast program.
[0081]
Subsequently, based on the control identification information, it is determined whether the instruction is to start reproduction prohibition or to cancel reproduction prohibition (Step 208). In this example, since the control identification information is “0”, it is an instruction to cancel the reproduction prohibition.
[0082]
Then, based on the time information, the time is determined (Step 211), and the reproduction prohibition is released (Step 212). In this example, since the time information is “19:33:00”, the reproduction prohibition is canceled from the frame whose time code is “19:33:00”. That is, the reproduction prohibition of the video / audio stream of the recorded baseball broadcast program, for example, the highlight scene A described in the first embodiment is canceled. That is, the highlight scene A that is freely recorded can be reproduced and viewed by the user's operation.
[0083]
In this way, playback of a scene recorded by the receiver 2 can be controlled.
[0084]
【The invention's effect】
According to the present invention, since recording control such as recording only a predetermined scene of a certain program is controlled from the broadcasting station side, recording can be performed in units of scenes without burdening the viewer. Excellent effect.
[0085]
In addition, according to the present invention, the playback of video / audio recorded under the control from the broadcast station side is also controlled on the broadcast station side. There is no such thing as watching another recorded scene.
