Description

  The present invention relates to a broadcast material editing apparatus that edits and transmits CM (commercial) material for TV (television) broadcasting and radio broadcasting, for example.

  As is well known, for example, in a CM transmission system that transmits CM material for TV broadcasting or radio broadcasting, a video server that records CM material and reproduces the CM material at an arbitrary timing is used.

  By the way, in such a system, CM material to be broadcast by TV broadcast waves is edited by a video editing device such as a VTR (Video Tape Recorder), and the edited CM material is transferred to a video server and recorded. ing. Also, when a CM material having the same content as a CM material broadcasted by a TV broadcast wave is broadcast by a radio broadcast wave, the CM material is edited by an audio editing device, and the edited CM material is transferred to a video server. Recording is performed in a storage area different from the CM material for TV broadcast waves.

However, in the system described above, most of the work up to the editing and broadcasting of the CM material is manually performed, so it takes a lot of time and effort to edit the CM, and human error is likely to occur. Conventionally, an image processing unit and an audio processing unit are separated by using a matrix switch to separate an editing processing path including an image processing unit and an audio processing unit from a signal path for sending CM material to be recorded on a VTR or the like. An editing system has been proposed in which recording to a VTR or the like is performed in parallel with the editing processing performed by a section (for example, Patent Document 1).
Japanese Patent Laid-Open No. 10-283725.

  However, in the editing system described above, it is necessary to provide the editing processing path and the recording path separately, which increases the system configuration. Further, even for the same CM material, it is necessary to edit the CM material separately for the TV broadcast wave and the radio broadcast wave, so that the editing work takes much time.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a broadcast material editing apparatus capable of performing processing from editing of a broadcast material signal to broadcasting in a simple and short time and greatly reducing the burden on the operator. is there.

In order to achieve the above object, the present invention is configured as follows.
In response to a recording instruction, a broadcast material signal including one or a combination of a video signal and an audio signal is recorded on a video server, and in response to a reproduction instruction, the broadcast material signal recorded on the video server is reproduced and output. In the broadcast material editing apparatus, a changeover switch that switches transmission paths of a plurality of input / output systems, a first signal transmitter that is connected to at least a part of input terminals of the changeover switch and sends out a video signal, and a changeover switch The first signal transmitter is connected to an input terminal to which the first signal transmitter is not connected, and is connected to a second signal transmitter that transmits an audio signal, and at least a part of output terminals of the changeover switch, and the first and second signal transmitters A signal synthesizer that combines the video signal and audio signal output from each of them to output to the video server as a broadcast material signal, and a recording instruction to the video server. Depending on, in which as provided any of the first and second signal transmission unit to output the video signal and any audio signal to the signal combiner, and a controller for controlling the selector switch.

  According to this configuration, the first signal transmitter is connected to at least a part of the input terminals of the changeover switch, and the second signal transmitter is connected to the input terminal to which the first signal transmitter is not connected, A signal synthesizer is connected to the output terminal of the changeover switch. The controller controls the sending of the first and second signal transmitters, and after matching the input timing to each changeover switch, Switching control is performed to synthesize an arbitrary video signal and an arbitrary audio signal with a signal synthesizer, and record them on a video server.

  Therefore, the video signal and the audio signal are sent from the video signal and the audio signal to the video server only by recording the video signal in the first signal transmitter and recording the audio signal in the second signal transmitter. Since all the steps up to the recording process are performed by a single controller without human intervention, the broadcast material signal combining the video signal and the audio signal is edited and recorded on the signal transmitter. It is not necessary to prepare the program, and the processing from the editing of the broadcast material signal to the broadcast can be performed easily and in a short time, and the burden on the operator can be greatly reduced.

  Also, among the video signal recorded in the first signal transmitter and the audio signal recorded in the second signal transmitter, those that can be used in the broadcast material signal broadcast in the future can be used again. In this respect, the process from editing the broadcast material signal to broadcasting can be performed easily and in a short time, and the burden on the operator can be greatly reduced.

The first signal transmitter transmits at least one of a still image signal and a moving image signal as a video signal.
According to this configuration, for example, when broadcasting a broadcast material signal based on a combination of a still image signal and an audio signal as in a local CM, it is only necessary to read an arbitrary still image signal from the first signal transmitter. Conventionally, processing from editing of a broadcast material signal to broadcasting can be performed easily and in a short time compared to a case where an operator combines a still image signal and an audio signal.

  Furthermore, the first and second signal transmitters of the changeover switch are connected to an input terminal to which the switch is not connected, and a third signal transmitter for transmitting a data signal different from the video signal and the audio signal is provided.

  According to this configuration, a broadcasting material signal combining an arbitrary video signal, an arbitrary audio signal, and an arbitrary data signal can be easily obtained by simply connecting a third signal transmitter to an empty input terminal of the changeover switch. Can be generated.

  As described above in detail, according to the present invention, there is provided a broadcast material editing apparatus capable of performing processing from editing of a broadcast material signal to broadcasting easily and in a short time and greatly reducing the burden on the operator. Can be provided.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows the configuration of a broadcast material editing apparatus according to an embodiment of the present invention. Reference numeral 11 denotes a matrix switcher. Here, for the sake of simplicity of explanation, the number of input channels (systems) of the matrix switcher 11 is four and the number of output channels is two.

  In this embodiment, a VTR 12 is connected to the first input channel of the matrix switcher 11, a DVD (Digital Versatile Disk) recorder 13 is connected to the second input channel, and an audio material transmitter (MD1) is connected to the third and fourth input channels. , MD2) 14, 15 and a video / audio synthesizer (movie / sound combiner) 16 is connected to the first and second output channels. These may be incorporated in one case, but the matrix switcher 11 is installed in the network management room, and the VTR 12, the DVD recorder 13, the audio material transmitters 14 and 15, and the video / audio synthesizer 16 are arranged in each studio. It may be.

  A video server 17 is connected to the output terminal of the video / audio synthesizer 16. The matrix switcher 11, VTR 12, DVD recorder 13, audio material transmitters 14 and 15, and video server 17 are connected to a terminal device 19 as a controller via a control LAN (Local Area Network) 18.

  The terminal device 19 causes the VTR 12, the DVD recorder 13, and the audio material transmitters 14 and 15 to transmit arbitrary video material and arbitrary audio material according to a control command by a user-specified input operation, and controls the matrix switcher 11. Connect any input / output channel according to the command. Then, recording start control is performed on the video server 17. The control command includes timing information indicating when it is executed.

Next, the processing operation in the above configuration will be described. FIG. 2 is a flowchart showing a control processing procedure of the terminal device 19.
When recording CM material on the video server 17, the operator activates the terminal device 19. At this time, it is assumed that the matrix switcher 11, the VTR 12, the DVD recorder 13, the audio material transmitters 14 and 15, and the video server 17 are in a power-on state.

  Then, the terminal device 19 displays a list of video / audio materials recorded in the VTR 12, the DVD recorder 13, and the audio material transmitters 14 and 15 on the display 191 (step ST2a). In this state, when the operator selects and designates the video / audio material desired to be recorded by the keyboard / mouse 192, that is, when the recording start button is pressed, the terminal device 19 shifts from step ST2b to step ST2c, where A playback start control command is sent to the VTR 12 and the audio material transmitter 14 in which the selected video material and audio material are recorded, and the VTR 12 and the audio material transmitter 14 and the video / audio synthesizer 16 are sent to the matrix switcher 11. And a control command for starting recording is sent to the video server 17.

  The video material and the audio material transmitted from the VTR 12 and the audio material transmitter 14 are synthesized by the video / audio synthesizer 16 to become one CM material, and then recorded on the video server 17 as an SDI embedded signal.

  When the switching timing of the video or audio material comes during the recording, the switching point of the matrix switcher 11 is switched to select another material. At the time of switching, the system is such that the appearance of cuts and the like does not occur in the video, and noise does not get on the audio. This depends on the specifications of the matrix switcher 11.

The CM material recorded in the video server 17 can be viewed on the video monitor / audio speaker 20 by preview reproduction.
In step ST2b, when the operator does not input a selection instruction as in the case where the operator temporarily stops the selection instruction of the video material / audio material, the terminal device 19 ends the process.

  As described above, in the above embodiment, the VTR 12 is connected to the first input channel of the matrix switcher 11, the DVD recorder 13 is connected to the second input channel, and the audio material transmitters 14 and 15 are connected to the third and fourth input channels. And the video / audio synthesizer 16 is connected to the output channel. In the terminal device 19, the VTR 12, the DVD recorder 13, and the audio material transmitters 14 and 15 are controlled to be transmitted to the respective matrix switchers 11. After matching the input timing, the switching control of the matrix switcher 11 is performed, and the video / audio synthesizer 16 synthesizes an arbitrary video material and an arbitrary audio material and records them on the video server 17.

  Therefore, the video material is recorded in the VTR 12 and the DVD recorder 13 and the audio material is recorded in the audio material transmitters 14 and 15, and the CM material from the transmission processing of the video material and the audio material to the video server 17 is recorded. Since all the steps up to the recording process are performed by one terminal device 19 without human intervention, the CM material combining the video material and the audio material is edited and recorded on the VTR 12 or the DVD recorder 13. This makes it possible to perform the process from the editing of the CM material to the broadcast easily and in a short time, thereby greatly reducing the burden on the operator.

  Moreover, since the audio material recorded in the VTR 12 and the audio material recorded in the audio material transmitter 14 can be used again in the CM material to be broadcast in the future, it is also possible to edit the CM material in this respect. Processing up to broadcasting can be performed easily and in a short time, and the burden on the operator can be greatly reduced.

  Further, in the above embodiment, still image material is recorded on the DVD recorder 13, and for example, when broadcasting CM material by a combination of still image material and audio material such as a local CM, the DVD recorder 13 arbitrarily Because it is only necessary to read out still image material, it is easier and simpler to process CM material from editing to broadcasting than when editing still image material and audio material in combination with an operator. Can do.

  In the above embodiment, when there is a vacancy in the input channel of the matrix switcher 11, it is possible to connect a transmitter in which data material consisting of character or text data is recorded. In this way, it is possible to easily generate a CM material in which an arbitrary video material, an arbitrary audio material, and an arbitrary data material are combined.

  In the above embodiment, an example in which CM material is handled has been described. However, for example, a broadcast program or the like may be handled.

  In addition, the configuration of the broadcast material editing apparatus, the control procedure of the terminal device when recording the CM material on the video server, and the contents thereof can be variously modified and implemented without departing from the gist of the present invention.
