DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a video signal transmitting apparatus, and more particularly, is suitable for use in a broadcasting system used in a broadcasting station.
BACKGROUND ART
Heretofore, this type of broadcasting system adopts a method that information such as title, shooting time and date, cameraman, and shooting scene (hereinafter, referred to as attendant information) are added to news materials to manage a shot video when a video signal of news materials is transmitted from the shooting scene to a broadcasting station, so as to make an edition of news television programs easier.
More specifically, in a broadcasting system shown in FIG. 1, a video signal obtained by shooting a video at a shooting scene by a shooting unit 2 containing a television camera, etc. is transmitted from an out-side broadcast van 3 to a broadcasting station STN via a transmission line 4 which is a satellite circuit or a ground circuit.
A receiving unit 5 of the broadcasting station STN stores the transmitted video signal for each news material in a recording medium in a video signal storing unit 6 having a large capacity which is, for example, a cassette changer. The video signal of each news material stored in the video signal storing unit 6 is selectively picked up in accordance with editing operator's demands from a plurality of editing units 7A to 7N and edited as news television programs for on air.
Here, the editing operators of respective editing units 7A to 7N edit while the operators refer to the attendant information as keyword information representing the contents of news materials.
Also, in the case where the video signal of news materials is recorded in a recording medium 8 which is a video tape or the like and delivered directly to the broadcasting station, the recording medium 8 in which the video signal made in the shooting unit 2 is recorded is put in the video signal storing unit 6 as it is.
The attendant information is added to the video signal for each news material and transmitted to the broadcasting station STN as described above, so that the editing operators can edit at the broadcasting station while confirming "When the video is shot", "Where the video is shot", "Who shot the video", and "What is the video", by using the attendant information as a keyword.
In the aforesaid structure of a broadcasting system 1, it can be considered that the attendant information is superimposed on the video signal as a method of adding the attendant information to the video signal. However, in the use of such a method, as shown in FIG. 2, the attendant information AR1 appears on a screen, thereby it can not be used as a video for broadcasting. Therefore, a method is practically used that the attendant information is superimposed only to the head of the video when the object to be covered is shot by the shooting unit 2, or that the attendant information is formed by voice instead of the superimposing to the video.
Further, a method is used in which the circuit different from a circuit for transmitting the video signal is set up to transmit the attendant information, the attendant information is printed with bar-code to a label, etc., and the label is affixed to the recording medium 8. In this method, a signal memory unit only for the attendant information is provided separately from the video signal storing unit. The correspondence between the attendant information stored in the signal memory unit and the video signal stored in the video signal storing unit (the correspondence being which portion of the video signal storing unit the video signal corresponding to the attendant information is stored in allows the absolute address number in which the video signal is stored to be generally added to the attendant information) is performed in accordance with the decision of operators.
The video signal to be transmitted in which the attendant information is added in the above way is displayed on a monitor (not shown) with the portion in which the attendant information is added, by the editing operators in
