Description

  The present invention relates to a program material display apparatus for displaying a program material signal recorded on a video server in a broadcasting station or reproduced and output from the video server, and a display method therefor.

  As is well known, in a broadcasting station, for example, broadcast program data such as a television broadcast or a radio broadcast program, a CM (commercial), a program using characters and data, etc. is stored in a memory and broadcast from the memory at an arbitrary timing. A video server for reproducing program data is used.

  In addition, the broadcasting station multiplexes and broadcasts super-material signals such as “provide” and “re-broadcast” on the video signal of the broadcast program, separates and demodulates the multiplexed signal on the receiver side, and displays the video screen of the viewing program in advance. Super material is displayed at a predetermined display position.

  On the other hand, digital broadcasting has been started in the terrestrial broadcasting system. In this digital broadcasting, in addition to the current 525-line television broadcasting, there are 1125-line television broadcasting and the like on the broadcasting station side. It is necessary to confirm the super-superimposition position and superimposition timing in advance.

Conventionally, there has been proposed a super synthesizer that can confirm the display position of a super material superimposed on the screen of a broadcast program video signal in a broadcasting station (for example, Patent Document 1).
JP-A-5-48963.

  However, the super synthesizer is installed in a broadcasting station separately from a display device for program material recorded in a video server, for example. For this reason, the system configuration in the broadcasting station becomes extremely large, and the equipment cost becomes expensive.

  Therefore, there has been a strong demand for an apparatus that can confirm the display position / superimposition timing of the super material on the display device of the program material recorded on the video server.

  Accordingly, an object of the present invention is to provide a program material display device capable of confirming in advance the display position / superimposition timing of the super material on the display screen of the broadcast program while reducing the size and price of the system configuration, and its display It is to provide a method.

  In order to achieve the above object, a program material display device according to the present invention is a program material display device for displaying a program material signal recorded on a video server or reproduced and output from a video server. Are connected to at least one input terminal to which the video server is connected to at least one input / output system of the plurality of input / output systems, and at least a part of the input terminals to which the video server of the switch is not connected, and is superimposed on the program material signal. A signal transmitter that transmits a super material signal and an output terminal that is connected to at least a part of the output terminals of the changeover switch, and that is reproduced and output from the video server by controlling the video server, signal transmitter, and changeover switch according to an instruction input The program material signal and any super material signal sent from the signal transmitter are captured and combined. Allowed by those you like and a material knitting monitor means for previewing.

  According to this configuration, the video server is connected to at least some input / output terminals of the changeover switch, the signal transmitter is connected to the input terminal not connected to the video server, and the material composition monitor is connected to the output terminal of the changeover switch. In the material organization monitoring means, the video server and the signal transmitter are controlled so that the input timing to the changeover switch of the program material signal and the super material signal is matched, and the changeover switch is controlled. The program material signal and the super material signal are combined and previewed. That is, the super material is displayed on the video screen of the program material signal on the existing video server, signal processor, and terminal device.

  Therefore, it is not necessary to use a dedicated super synthesizer for displaying the super material on the video screen of the program material signal, thereby preventing an increase in system configuration and cost, and the program material signal and super material signal. Prior to the broadcast, confirmation of the display position and superimposition timing of the super material on the screen of the program material signal can be performed with one terminal device. Thereby, it is possible to prevent the display timing shift of the super character and the problem that the character covers the image of a person or the like. Further, for the purpose of confirmation only, the super material is superimposed on the program material in the video server at the time of reproduction, and only the screen preview is performed, and it is not necessary to change the program material itself.

  As described above in detail, according to the present invention, the program material display that can confirm the display position / superimposition timing of the super material on the display screen of the broadcast program in advance while reducing the size and price of the system configuration. An apparatus and a display method thereof can be provided.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a configuration of a program material display 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 three.

  In this embodiment, the video server 12 is connected to the first input channel of the matrix switcher 11, the super material transmitter 13 is connected to the second input channel, the video server 12 is connected to the first output channel, the second and A super superimposer (SUP AMP) 14 is connected to the third output channel.

  A monitor / speaker 15 is connected to the output terminal of the super superimposer 14. The matrix switcher 11, the video server 12, and the super material transmitter 13 are connected to a terminal device 17 as material composition monitoring means via a control LAN (Local Area Network) 16.

  The terminal device 17 causes the video server 12 and the super material transmitter 13 to transmit an arbitrary program material and an arbitrary super material according to a control command by a user-designated input operation, and causes the matrix switcher 11 to perform an arbitrary operation according to the control command. Connect between input and output channels. The control command includes timing information indicating when it is executed.

  An arbitrary program material and an arbitrary super material output from the matrix switcher 11 are combined by the super superimposer 14, and this combined material is previewed by the monitor / speaker 15.

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 17.
When recording a program material (material A) on the video server 12, the operator activates the terminal device 17 and activates a dedicated application. Then, a recording material is selected from the list displayed on the display 171 and recorded on the video server 12. After recording the material A on the video server 12, a super material is prepared (referred to as material B). At this time, the matrix switcher 11, the video server 12, and the super material transmitter 13 are assumed to be in a power-on state.

  Then, the terminal device 17 displays a list of program materials and super materials recorded on the video server 12 and the super material transmitter 13 on the display 171 (step ST2a). In this state, when the operator selects and designates the material A and the material B desired to be sent by the keyboard / mouse 172, the terminal device 17 proceeds from step ST2b to step ST2c, where the material A and the material A and In order to send a playback start control command to the video server 12 on which the material B is recorded and the super material transmitter 13, and to connect the video server 12, the super material transmitter 13 and the super superimposer 14 to the matrix switcher 11. Send the control command.

  In step ST2b, when the operator does not input a selection instruction as in the case where the operator temporarily stops selecting the material A and the material B, the terminal device 17 ends the process.

  The material A and the material B sent from the video server 12 and the super material sending device 13 are combined by the super superimposing device 14 into one material, and then previewed on the monitor / speaker 15. Therefore, the operator can check the display position and superimposition timing of the material B to be superimposed on the material A screen by this preview screen display.

  In this state, if there is a problem with the display position and superimposition timing of the material B, the material A is corrected and prepared for broadcasting (on air). At the time of on-air, the material A is output to the master system (other than this device configuration), and the material B is superimposed on the material A on the master system side.

  As described above, in the above embodiment, the video server 12 is connected to the first input channel of the matrix switcher 11, the super material transmitter 13 is connected to the second input channel, and the super superimposer 14 is connected to the output channel. In the terminal device 17, the video server 12 and the super material transmitter 13 are controlled to be transmitted, the input timings to the respective matrix switchers 11 are adjusted, and the switching control of the matrix switchers 11 is performed. An arbitrary program material and an arbitrary super material are synthesized and previewed on the monitor / speaker 15. That is, the super material is displayed on the video screen of the program material on the existing video server 12, super material transmitter 13, monitor / speaker 15, and terminal device 17.

  Therefore, it is not necessary to use a dedicated super synthesizer for displaying the super material on the video screen of the program material, which can prevent the system configuration from becoming large and costly, and also allows the program material and super material to be on-air. Prior to this, the monitor / speaker 15 can check the display position and superimposition timing of the super material on the video screen of the program material. Thereby, it is possible to prevent the display timing shift of the super character and the problem that the character covers the image of a person or the like. Further, for the purpose of confirmation only, the super material is superimposed on the program material in the video server at the time of reproduction, and only the screen preview is performed, and it is not necessary to change the program material itself.
