PCT No. PCT/EP95/01555 Sec. 371 Date Oct. 23, 1996 Sec. 102(e) Date Oct. 23, 1996 PCT Filed Apr. 25, 1995 PCT Pub. No. WO95/29556 PCT Pub. Date Nov. 2, 1995The invention concerns a high frequency image transmission system comprising several shooting units (Ci) comprising a camera, a receiver (HFR) and a transmitter (HFE) able to transmit a video signal to a central production unit (S), and two video channels respectively allowing transmission on a first and a second predetermined carrier frequency (Fi, Fj). This system is characterized in that said central production unit comprises a control unit (UC) for transmitting a control radio signal to said shooting units to control remotely their operation and for controlling the assignment of said channels so that one of said channels transmits, on one of said carrier frequencies (F1, F2), a first video signal coming from a selected shooting unit, while the other said channel transmits, on the other said frequency, a second video signal formed by temporal multiplexing of the signals coming from the other shooting units.
