[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a broadcast system for recording broadcast material having a video signal by a random access recording method and sending the recorded broadcast material, and in particular, it is easier to check the recording operation when recording the broadcast material. It relates to the improvement of the broadcasting system.
[0002]
[Prior art]
As digitalization of video signals progresses rapidly, broadcast materials consisting of video data signals and audio data signals, which are digital signals, are recorded in a randomly accessible storage device, and broadcast materials are sent according to instructions from the broadcast control device. As a result, broadcasting systems that perform broadcasting services are beginning to be operated at broadcasting stations.
[0003]
In the operation of such a broadcasting system, the recording results are sent from the output channel of the broadcasting system and displayed on a monitor etc. during the period from the recording of the broadcasting material to the use of the broadcasting, and the recorded contents are displayed. Check it. However, when the recording time of the broadcast material is long, a method of confirming the transmission result during the recording operation is often used, and this confirmation operation is called simultaneous reproduction.
[0004]
Hereinafter, a conventional broadcasting system will be described with reference to FIG. First, the video / audio signal output from the material playback device 101 is recorded as a broadcast material in the recording device 102. The recording device 102 immediately outputs the material recorded from the output channel to the video display device 103, and the video display device. It is played back at 103.
In the broadcasting system using the storage device 102, a plurality of output channels are prepared. However, in the simultaneous playback, the video display device 103 can be connected to play back video regardless of which output channel is used. However, when the output channel is used for a sending operation in response to an instruction from the automatic sending device 203, or an operator other than the operator who performs the simultaneous playback performs other simultaneous playback, material content confirmation, and material editing. When performing operations such as the above, it is necessary to find an empty output channel for each operation and operation and distribute the operation to the operation or operation.
[0005]
For this reason, in the broadcasting system, all the input / output channels of the storage device and the devices used for recording, for example, the material playback device 101 and the video display device 103 are controlled collectively by a single control device 201. Recording and sending control are performed while managing so that output channel contention does not occur. In FIG. 2, the control device 201 manages the use of the output channel according to the operation contents from the automatic transmission device 203 and the console 202, and thereby controls the storage device 102.
[0006]
In addition, by giving priority to the purpose of use of the input / output channel, for example, when using the output channel for a purpose of high priority such as transmission operation for broadcasting, priority such as simultaneous playback is used. Ensure that the use of the output channel for low-use purposes is interrupted. In FIG. 2, it is assumed that the storage device 102 has four output channels. For example, it is assumed that there are three consoles that perform simultaneous playback operations, one console that performs sending operations, and all four output channels are used corresponding to these four consoles. In this case, when another new transmission operation is started, the output channel used for the simultaneous reproduction is now assigned to the new transmission operation in order to give the new transmission operation a higher priority than the simultaneous reproduction. Used for operation, one simultaneous playback is interrupted.
[0007]
[Problems to be solved by the invention]
When performing a recording operation using a priority-based channel sharing method that assigns a higher priority to the sending operation than the simultaneous playback at the time of recording, priority is given to the output channel during simultaneous playback in the sending operation. When starting to use, the video display due to the simultaneous playback is interrupted, but the recording work itself is interrupted at this time, considering that the recorded broadcast material has a certain length or longer. Inefficient.
[0008]
However, if you continue recording without simultaneous playback, sending the material that has not been played back as it is, it has not been confirmed that the recorded video signal has no flaws. I'm still worried about the broadcast. Therefore, it is necessary to check the material content after recording. Therefore, it is necessary to clearly distinguish broadcast materials for which simultaneous reproduction is interrupted or broadcast materials for which simultaneous reproduction has not been performed from the beginning.
[0009]
The object of the present invention is to record the broadcast material when the broadcast material is not simultaneously reproduced at the time of recording the broadcast material or when only a part of the image is displayed for simultaneous reproduction. At the same time, information indicating that the simultaneous reproduction is not completed is recorded, and by confirming the recorded content, it is possible to immediately confirm that the simultaneous reproduction is not completed.
[0010]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention is a system for recording and broadcasting broadcast material composed of video and audio signals. When the broadcast material is not simultaneously reproduced at the time of recording the broadcast material, or a part thereof However, when video display for simultaneous playback is not performed, information indicating that simultaneous playback is not completed is recorded together with the recorded broadcast material, and a plurality of broadcast material output channels are recorded. Is shared among multiple applications and automatically assigns output channels, the priority is given according to the purpose of use of the output channel, and the output channel is used for a higher priority when there is no available output channel. When starting to use, the use of the output channel that is in use for a lower-priority usage is suspended, and the output channel is assigned to a higher-priority usage. It is intended.
[0012]
In addition, the present invention performs simultaneous playback that automatically plays back on available channels when recording broadcast materials, and processes the simultaneous playback video to save the representative screen of registered video material as one or more still images. It is used for material management.
Furthermore, the present invention continues the recording if the simultaneous playback is interrupted when the output channel is used for a higher priority during the simultaneous playback at the time of recording, and simultaneously plays back on the representative screen of the registered material after recording. It is possible to confirm that has been interrupted.
[0013]
Further, in order to solve the above-described problems, the present invention displays a simultaneous playback moving image on an operation console, captures the video as a still image, and stores it as a representative screen of the material. The representative screen includes an image of the top part of the material, and can be used when managing the material later. Since the representative screen is created during simultaneous playback, it cannot be created if simultaneous playback has not been performed. In such a case, a special still image file indicating "interrupt of other work" is prepared, and the still image file is used as a representative screen, so that the material that was not played simultaneously and the material that was played simultaneously are displayed. Can be distinguished. In addition, even if the output channel that is playing simultaneously is switched as the output channel for sending operation, the created representative screen must be discarded and used as the “interrupt for other tasks” representative screen, so that simultaneous playback has not been completed. Can know. Similarly, when the simultaneous playback channel cannot be secured when the simultaneous playback is started, it is possible to know that the simultaneous playback is not completed by using the “interrupt for other tasks” representative screen.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a block configuration of an embodiment of a broadcasting system of the present invention. In this figure, since the part which attached | subjected the same code | symbol as the above-mentioned FIG. 2 was mentioned above, description is abbreviate | omitted.
1 is different from FIG. 2 in that a control signal a is output from the control device 201 to each console 202. Also, the video signal output to the video display device 103 during simultaneous playback is output from the storage device 102 to the corresponding console 202. The control signal a is a control signal corresponding to the output channel control of the control device 201. Hereinafter, the operation of the present invention using the control signal a will be described.
[0015]
First, when simultaneous playback at the time of recording is performed, the control device 201 confirms whether one of the output channels of the storage device is free. If the output channel is vacant, the recorded broadcast material for simultaneous reproduction is output using the output channel. Then, the control device 201 outputs a control signal a for notifying that the simultaneous playback is possible to the console 202 on which the operation for performing the simultaneous playback has been performed. In response to the input control signal a, the console 202 displays to the operator that the simultaneous playback operation has been started or that simultaneous playback is possible. Then, the operator recognizes that simultaneous playback is performed by the display, and can confirm the playback content of the recorded broadcast material by the simultaneous playback by viewing the video and audio displayed on the video display device 103. it can. Further, a video signal having the same content as the video signal for simultaneous playback is output from the recording device 102 to the console 202 on which the operation for performing the simultaneous playback has been performed. The console 202 generates a representative screen video signal representative of the broadcast material based on the input video signal, and records the representative screen video signal generated corresponding to the simultaneously reproduced broadcast material. Therefore, by confirming after recording that there is a representative screen video signal recorded corresponding to the recorded broadcast material that is played back simultaneously, it is possible to immediately confirm that the simultaneous playback of the broadcast material has been performed normally. Can do.
[0016]
Next, when the above-mentioned simultaneous reproduction is performed, it is necessary to perform a material transmission operation (transmission work) for broadcasting, for example, which has a higher priority for using the output channel than the simultaneous reproduction. A case where all of the plurality of output channels of the recording apparatus 102 are already used for outputting a predetermined video signal including simultaneous reproduction will be described. In this case, for example, the control device 201 that has received a transmission operation instruction from the automatic transmission device 203 detects an output channel used for an operation (business) having a lower priority among the output channels. Therefore, an output channel having a lower priority, for example, used for simultaneous reproduction is detected, and the detected output channel outputs a video signal for a material transmission operation (transmission service) at a time according to the instruction. Switch to operation. The control device 201 outputs a control signal a indicating that the output channel has been switched to another job to the console 202 that has issued an instruction to use the output channel for simultaneous reproduction. The console 202 to which the control signal a is inputted determines that the simultaneous reproduction of the currently recorded material does not end normally. Therefore, the console 202 in advance provides a representative screen of the broadcast material being recorded. For example, a screen video signal for displaying “interrupt of other business” is recorded in association with the broadcast material.
[0017]
Also, when there is no empty channel from the beginning of the recording when performing simultaneous playback during recording, the console 202 is similarly notified, and the console 202 performs simultaneous playback of recorded materials. Knowing that there was not, the screen video signal for displaying “interrupt of other work” as the representative screen is recorded in association with the broadcast material. By doing so, when managing the broadcast material after recording, by checking the video on the representative screen, the broadcast material that has not been played back simultaneously can be detected immediately, and the detected broadcast material Can confirm the recording result by performing the playback operation again.
[0018]
FIG. 3 shows an example of a confirmation screen for recorded materials. A representative screen for recorded materials is displayed from a representative screen display column 701 to a representative screen display column 705. The part that cannot be displayed is displayed by operating the representative screen scroll bar 706. FIG. 4 shows “interrupt for other business” screens in the representative screen display fields 801 and 802 because the broadcast material of the program including the material that was interrupted for simultaneous playback was interrupted for other business and simultaneous playback could not be performed. Has been. In such a case, it is immediately understood that it is necessary to replay the broadcast material once again and confirm the recording result for these two broadcast materials. FIG. 5 shows a confirmation screen for a program for which an output channel cannot be acquired at the start of simultaneous reproduction, and “interrupt for other tasks” screens 901 to 905 are displayed in all representative screen display fields. In such a case, it is understood that it is necessary to replay the broadcast material for all these broadcast materials and confirm the recording result.
[0019]
In the above example, one representative screen video signal is recorded for each broadcast material, but a scene break of the broadcast material is detected, and one representative screen video signal is recorded for each scene. Anyway. In this case, with regard to the simultaneous playback of recorded materials, there is an interruption of other work for the scene in units of scenes, not in units of broadcast materials, and the simultaneous playback could not be performed, so the representative screen video signal representing that scene is “Other Record the screen video signal that displays “business interruption” in association with the recorded video signal for each scene. By doing so, it is possible to instantly detect only the scenes where simultaneous playback did not end normally for each scene out of broadcast materials that did not end normally simultaneously, so to check the recording results after recording If the broadcast material is reproduced only for the detected part, the recorded contents can be confirmed in a shorter period of time for all scenes together with the simultaneous reproduction.
[0020]
【The invention's effect】
According to the present invention, in a broadcasting system in which a plurality of output channels are shared in a plurality of applications, it is possible to effectively use channels that are not used, and immediately after recording materials that could not be reproduced simultaneously on the representative screen. Since it can be confirmed, it is easier to confirm the recorded content.
