Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video signal recording apparatus, an editing method and a system thereof suitable for being applied to, for example, an editing system.

[0002]

2. Description of the Related Art Conventionally, in a broadcasting station, video and audio used in a program are recorded by using a camera-integrated VTR.
Video and audio recorded on tape cassettes are often used. All of the video and audio information recorded on the video tape recorder by the camera-integrated VTR is rarely used in the program, and most of them are extracted and used by the editing process. Often. The processing procedure from recording of video and audio information by the camera-integrated VTR to the video tape cassette to editing of the recorded video and audio information is as follows, for example.

By keeping the camera-integrated VTR in a recording state during the data gathering, the video and audio information of the target subject is recorded in the video tape cassette. Next, the video tape cassette is set in the VTR for editing processing, and the V key is operated by operating the operation key group of the editing machine.
The TR is brought into the reproduction state, the reproduced video and audio information is monitored, and at that time, desired IN point and OUT point are designated to the editing machine. As a result, the editing machine uses the reel ID data of the video tape recorder, the time code data of the in point and the out point, and the like as floppy (registered trademark) data as EDL (edit list) data.
Record on a disc, etc. The above is so-called offline editing.

Subsequently, online editing is performed to specify the material to be actually broadcast in more detail. What is needed at this time is a floppy disk on which the edit list data created during offline editing is recorded and a video tape cassette on which the material is recorded. The video tape cassette is set in the VTR for online editing, and the floppy disk is set in the floppy disk drive connected to the editing machine for online editing.

As a result, the editing machine for online editing reads the edit list data from the set floppy disk and records it on the set video tape cassette based on the read edit list data. Of the video and audio information, the video and audio information in the range specified on the edit list data is sequentially reproduced. The editor who performs online editing monitors the playback video and audio information while performing more detailed setting processing of the IN and OUT points, and also sends the playback video and audio information that is played back based on the edit list data. The video tape cassette set in the VTR is recorded. Of course, the video tape cassette containing the material was set in the cassette autochanger, and based on the edit list data,
It may be reproduced and transmitted as it is at a preset broadcast time.

[0006]

By the way, as described above, the problem in the editing process is that since the recording medium is a video tape cassette, the in point and the out point at the time of off or online editing. This is a decrease in editing efficiency due to processing such as fast forward and rewind when determining. Since the video tape cassette is a tape-shaped recording medium, for example, in order to determine the IN point, the position on the magnetic tape of the video tape cassette containing the material is set to the head position, or In order to decide where to use it, it is necessary to play it from the beginning position for a long time, and the most time is spent in the editing process, rather than the editing content itself, rather than the editing content itself. It is no exaggeration to say that it is the running time of the tape-shaped recording medium for setting the position to the desired position.

The present invention has been made in view of the above points, and it is an object of the present invention to propose a video signal recording apparatus, an editing method and a system thereof capable of greatly improving the editing efficiency.

[Effects of the Embodiment] As described above,
In the present embodiment, when recording with a camera-integrated VTR, captured video and audio signals are recorded on the video tape cassette without compression, and the IC card 252 is used.
In this example, the captured video and audio signals are compressed and recorded, and at that time, the blood pressure data and pulse data from the sphygmomanometer 148 and the position data from the GPS 147 are also recorded in the subcode area of each signal. To do.

Next, in the offline editing system, the in and out points are determined by referring to the compressed video and audio signals recorded in the IC card 252, the blood pressure data, the pulse data, and the position data. The edit list data Da3 is generated, and the edit list data Da3 is stored in the floppy disk 3
Record at 63.

Next, in the online editing system, the edit list data Da3 is read from the floppy disk 363, the contents are changed as necessary, and the camera integrated type is used based on the changed edit list data Da3. The VTR automatically reproduces a necessary portion of the video tape cassettes 501-1 to 501-n in which the material is recorded and records or sends the reproduced data.

Therefore, as compared with the case where the tape-shaped recording medium is used from the beginning to the end of the editing process, the editing efficiency at the time of editing, in which the IN point and the OUT point are designated, can be greatly improved, and Since the editing can be performed by referring to the additional data such as the blood pressure data, the pulse data, and the position data, it is possible to obtain the editing result more in line with the photographer's intention. For example, rather than deciding the editing point while looking at the image displayed on the monitor, it may be possible to perform editing more in line with the photographer's intention by setting the point where the blood pressure or pulse of the photographer rises as the editing point. There is. For example, if a photographer captures a precious creature for only a moment, finding the image at that moment on the magnetic tape of a video tape cassette is time-consuming and sometimes overlooked. In such a case, there is a high possibility that the blood pressure or the pulse will rise, so if the position where the blood pressure or the pulse is rising is searched, the most valuable part can be searched in a short time.
