System and method for high frequency transmission of television shots

High frequency television image transmission system comprising:

• at least three shooting units each comprising a camera and a module comprising a radio wave receiver and a high frequency transmitter (HFE) able to transmit via radio waves a shot signal provided by said camera to a central production unit capable of communicating with a television network for broadcasting live and/or recording at least one of said signals,
• two hertzian video channels allowing respectively the transmission on a first and a second predetermined carrier frequency of a video signal representing a determined number of images per second, said channels linking said shooting units to said central production unit,
• said central production unit comprising a control unit comprising means for establishing a radio wave link with said receivers of said shooting units, the system being characterized in that
• said linking means are arranged so that they can transmit a control radio signal to said shooting units for remote controlling the operation of said shooting units, their transmitters and their receivers and for controlling the assignment of said channels to said shooting units so that one of said channels transmits, on one of said carrier frequencies, a first video signal formed by the shot signal coming from a selected shooting unit, while the other of said channels transmits, on the other of said carrier frequencies, a second video signal formed by temporal multiplexing of the shot signals coming from the other shooting units, and in that said control unit transmits said control radio signal to said shooting units for each image so as to validate, image by image, the operation of said module (Md.sub.i) and the turning on of said transmitter (HFE).
