Abstract

PROBLEM TO BE SOLVED: To receive the video signal entered at a higher speed than that equivalent to real time and to connect many more edit execution sequencing list generating means to a 2nd storage means by storing the video signal subject to non-compression or compression at a low compression rate to a 1st storage means, expanding the signal in real time, compressing the signal at a high compression rate and storing the signal to a 2nd storage means. SOLUTION: In a news program production broadcast system 20, video audio data D10 at a high real speed are subject to high compression coding as they are and the data D10 are divided into video audio data 11 when the speed is higher, expanded into real time, subject to high compression coding and the result is stored in a clip server 33. Then edit execution sequencing list (EDL) generators 34A-34N generate EDLs based on high compression coding data D12 and EDL execution devices 40A-40C conduct edit processing of the video audio data D10 based on the EDL. Thus, many more persons confirm the contents of the video audio data D10 and generate the EDL.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video signal processing apparatus and a video signal processing method, and is suitably applied to, for example, a news program production and broadcast system.

[0004]

2. Description of the Related Art Conventionally, as one of the news program production and broadcasting systems in a broadcasting station, there is a system configured as shown in FIG.

In the news program production / broadcasting system 1 having such a configuration, first and second AV (Audio Video) servers 2 and 3 having a recording / reproducing section having a disk array configuration.
And a plurality of editing devices 4A to 4N, a system control unit 5 for controlling the entire system 1 and a data storage device 6 storing various data are connected via a network 7. Have been. And the first AV
Uncompressed or low-compressed video / audio data D1A to D1N transferred from a news gathering site via a transmission line or reproduced from a news gathering tape are supplied to the server 2 by a plurality of systems.

At this time, the first AV server 2 supplies the supplied video / audio data D under the control of the system control unit 5.
A plurality of systems of video and audio data D1 (D1A to D1N) specified from among 1A to D1N are fetched at the same time, filed, and stored in the designated address position of the recording / reproducing unit.

The video / audio data D1 of each file stored in the first AV server 2 is
A to 4N can be simultaneously read from the first AV server 2 using a plurality of files, and the video based on the read video and audio data D1 can be monitored and displayed on the editing devices 4A to 4N, respectively. .

The operator operates the editing devices 4A to 4A.
N, while visually checking the video displayed on the monitor N, a list (hereinafter referred to as EDL (hereinafter referred to as EDL) which defines how to edit and edit the video / audio data D1 to create a new video for broadcasting. Edit Decision List) can be created, and the created EDL can be registered in the editing devices 4A to 4N and executed.

In practice, when executing the EDL, the editing devices 4A to 4N read out the necessary video / audio data D1 by controlling the first AV server 2 and process and edit the data based on the EDL. The video / audio data D2A to D2N obtained by the processing are sent to the second AV server 3.

At this time, under the control of the system control unit 5, the second AV server 3 sequentially takes in the supplied edited video / audio data D2A to D2N, file them, and designate them as a recording / reproducing unit. At the specified address location.

Although a case has been described in which the EDL creation devices 34A to 34N having a personal computer configuration are applied as creation means, the present invention is not limited to this, and other various configurations can be applied.

Further, in the above embodiment, the ED
The editing execution order list executing means for processing and editing the uncompressed or low-compressed video / audio data D10 stored and held in the daily server 30 on the basis of the EDL created by the L creating devices 34A to 34N. System control unit 26 that controls the entire broadcast system 20
And a plurality of EDL execution devices 40A to 40C are described. However, the present invention is not limited to this. For example, the operation states of the EDL execution devices 40A to 40C may be changed based on the created EDL. The control unit for controlling may be provided separately from the system control unit 26, and various other configurations can be applied as the configuration of the editing execution order list execution unit.

Further, in the above-described embodiment, a case has been described in which the present invention is applied to the news program production / broadcasting system 20 for producing / broadcasting a news program. However, the present invention is not limited to this. The present invention can be applied to various video signal processing devices in addition to processing and editing video signals to be processed.

[0079]

As described above, according to the present invention, the first storage means for storing an uncompressed or low-compressed video signal input to the video signal processing device at a speed higher than real time, and Input buffer means for decompressing the signal in real time, second storage means for storing the decompressed video signal with high compression, and creating an edit execution order list based on the high-compression video signal Based on the edit execution order list creation means and the created edit execution order list,
By providing the editing execution order list executing means for processing and editing the video signal stored in the first storage means, it is possible to capture a high-speed video signal,
The contents of the video signal stored in the first and second storage means can be confirmed by more people, and the editing execution order list can be created by more people. As a result, a video signal processing device capable of improving the efficiency of program production work can be realized.

According to the present invention, the video signal processing method stores an uncompressed or low-compressed video signal supplied at a higher speed than in real time, and expands the video signal in real time. A first step of storing with high compression;
A second step of creating an edit execution order list based on the highly compressed video signal, and a third step of processing and editing the stored uncompressed or low-compressed video signal based on the created edit execution order list. By providing the steps, a high-speed video signal can be captured, and more people can confirm the content of the stored video signal based on the stored high-compression video signal, and more. The editing execution order list can be created by many persons. As a result, a video signal processing method that can improve the efficiency of program production work can be realized.
