In fact, the production of news programs, after making a report schedule in the news department, each branch office,
In order to quickly edit news sources covered by a branch or club and broadcast within a limited airtime,
On-air transmission is performed according to a cue sheet (program progress table) indicating the contents of the program and the broadcast time of each item constituting the program. The cue sheet on which the broadcast information of the program is written is created based on the broadcast schedule of the broadcast station.

In recent years, a data recording / reproducing apparatus called a video server (or AV server) for performing non-linear recording / reproducing using a randomly accessible recording medium instead of sequential (linear) recording / reproducing using a VTR tape has become widespread. I am doing it. Generally, a video server used as a broadcasting station equipment requires a high data transfer rate and a large storage capacity to enable long-time data recording due to requirements for image quality and sound quality. Is done. Therefore, RAID (Re-
Using dundant Arrays of Inexpensive Disks), material data consisting of multiple audio and video data is recorded in a distributed manner and transmitted simultaneously on multiple channels, or the same material data is played on multiple channels with a different playback time. By doing so-called VOD (video on demand) and NVO
D (near video on demand) can be realized.
This type of technology is described in, for example,
No. 7625.

Is registered in the still image relation, a still image relation is simultaneously transmitted to the on-air server controller terminal 9 via the LAN 8. As a result, in the on-air server controller terminal 9, a bitmap of “acquiring” is displayed at the position where the still image of the cue sheet is to be displayed. The bitmap “acquiring” is displayed until a still image is acquired.

On the other hand, in response to the file transfer request, the on-air server unit 22 receives the file transfer request from the stamp server 17, and stores the identification data (Index) and the frame position information of the material data specified in the file transfer request. In accordance with the time code, one frame of video data is extracted from the corresponding edited material data and sent to the stamp server 17. The stamp server 17 decodes the obtained video data of the still image, converts it into bitmap data, and registers the bitmap data in the database server 7. In the database server 7, the still image (bitmap data) is registered in the still image relation, and the status (Status) is changed to "1: acquired". Simultaneous image relation transmission is performed via the LAN 8. As a result, the on-air server controller terminal 9 displays the acquired still image at the position where the still image of the cue sheet is to be displayed.

As shown in FIG. 4, the cue sheet screen 11
5, items to be transmitted are arranged in order of transmission time, and each item includes at least one of the start time, item name, configuration time, and item of the item based on the program data C1.

The still images obtained by the above-described procedure are displayed as still images 116a and 116b in the video field of each item on the cue sheet screen 115.

As described above, according to the present embodiment, the LAN
Since the one cut (still image) of the video data is obtained through the interface 8, the input / output port provided in the on-air server unit 22 is not wasted. In addition, since the stamp server 17 captures a still image from video data by software, there is no need to provide a special device. Further, since a still image to be acquired is directly requested by the time code to the on-air server unit 22, operations such as heading of a material can be omitted.
