Processes for transmitting video signals, video cameras for such transmission and applications of such cameras

摘要

A video camera comprises a lens 1, and image analyzer 2, management circuits 3, an incorporated programmable oscillator 4, a modulator 5, an antenna 7, a scanning tuner 8 equipped with a tuning detector circuit 12 and an electronic calculating unit 10 which controls scanning of the tuner, which records the frequencies detected by the detector 12, which selects a free frequency different from a multiple or a sub-multiple of the frequencies detected and which controls the oscillator 4 for the latter to emit a carrier frequency equal to the free frequency.
