Abstract

1. A method for transmitting telemetric and video information with time-frequency compression of a radio channel and the analog-to-digital method of frequency (phase) modulation of the carrier frequency N (where N = 2, 4, 8 ...) by synchronous video streams, in each of which channel separation is carried out at the clock frequency F in time with a duty cycle of Q = 2, with each stream spaced from the adjacent carrier frequency by the frequency interval Δfp = F · n (where n = 5, 6, 7 ...) and shifted in time by half a cycle, characterized in that, in order to expand functionality, high frequency ny plunged video signal sampling time, reducing the resolution and frame rate, generating video pulses marker, then the received signals from one form of synchronous flows, which condense with telemetric data stream and transmitted on radiokanalu.2. A device for implementing the method according to claim 1, comprising a series-connected clock generator (1), a frequency divider (2), a marker pulse shaper (3), a phase detector (4), a frequency modulator (5), a controlled generator (6), and a power amplifier (7), a reference carrier frequency generator (8), the output of which is connected to the second input of the phase detector (4), to the third input of which the second output of the controlled generator (6) is connected, the first switch (9), the input of which is connected to the second the output of the clock generator (1), total OP (10), connected between the output of the first switch (9) and the second input of the frequency modulator (5), the second switch (11), connected between the third output of the clock generator (1) and the second input of the adder (10), frequency “stand” driver »(12), incl�
