Abstract

A method of transmitting news data with script can simultaneously transmit video information and corresponding added information such as gathered news information to a news center from a news gathering field by use of an existing news transmission system. Digital video data, obtained by a video camera in a field, is timebase-compressed, and digital audio data is prepared on the basis of an audio signal. Added information such as script information is prepared as digital added information, and composite news data is generated by time-division-mixing these video data, audio data, and added information data. The composite news data is transmitted to a video receiving station by use of a news gathering system. In the video receiving station, the composite news data is time-division-distributed, and the time-division-distributed data is timebase-expanded, and combined with time-division-distributed audio data thereby to generate a video image signal. Simultaneously, a script, which is a broadcasting script, is generated from the time-division-distributed added information data.

Claims

1. A video data transmitting apparatus for transmitting a source digital video signal prior to having editing performed thereon from a transmitting side to a receiving side, comprising:

video signal encoding means for encoding said source digital video signal to generate an encoded video signal at said transmitting side;

edit point data generating means for generating edit points data at said transmitting side comprising a plurality of edit points which are associated with said source digital video signal and which are used to define actual edits that are to be performed on said digital video at said receiving side, but which are maintained apart from source digital video data, and therefore do not edit the source digital video data at said transmitting side;

multiplexing means for multiplexing said encoded video signal and said edit points data to generate multiplexed data; and

data transmitting means for transmitting said multiplexed data from said transmitting side to said receiving side so that an editing operation is performed on said video data at said receiving side based upon said edit points data to generate edited video data.

2. The video data transmitting apparatus of claim 1, wherein said multiplexing means multiplexes time code data of said source digital video signal.

3. The video data transmitting apparatus of claim 1, wherein said edit points data further comprises at least one of event number, reel number, edit mode, edit transition type, edit transition time, wipe number, edit-in time and edit-out time.

4. The video data transmitting apparatus of claim 1, wherein said edit points data is contained within a header at a leading portion of each of a plurality of data blocks.

5. A method for transmitting a source digital video signal prior to having editing performed thereon from a transmitting side to a receiving side, comprising the steps of:

generating edit points data at said transmitting side comprising a plurality of edit points which are associated with said source digital video signal and which are used to define actual edits that are to be performed on said digital video at said receiving side, but which are maintained apart from source digital video data, and therefore do not edit the source digital video data at said transmitting side;

encoding said source digital video signal to generate an encoded video signal;

multiplexing said encoded video signal and said edit points data to generate multiplexed data; and

transmitting said multiplexed data from said transmitting side to said receiving side so that an editing operation will be performed on said video data at said receiving side based upon said edit points data to generate edited video data.

6. The method of claim 5, further comprising the step of multiplexing time code data of said source digital video signal.

7. The method of claim 5, wherein said edit points data comprises at least one of event number, reel number, edit mode, edit transition type, edit transition time, wipe number, edit-in time and edit-out time.

8. The method of claim 5, further comprising the step of positioning said edit points data within a header at a leading portion of each of a plurality of data blocks.
