FIELD: radio communications engineering. ^ SUBSTANCE: novelty is that newly introduced in prior-art system designed for telecasting in ultrahigh-frequency band over ground television networks and over satellite communication lines on sending end are three video-signal analog-to-digital computers, third code generator, pulse counter, flip-flop, and two switches, photoelectric converter is provided in addition with second lens, third piezodeflector, two dichroic mirrors, three microlenses, three photodetectors, and three preamplifiers, and third channel is inserted in transmitter; newly introduced on receiving end are third channel for receiving and processing video signal codes, optical projection system, radiator, and separate frame viewing unit, radiation modulation unit is provided in addition with second radiator of three basic colors. Effective frequency band is 316.8 Hz, number of active lines in frame is 800 with 1200 readings per line, frame repetition frequency is 50 Hz and that of resolving dots in frame is 960 000. ^ EFFECT: improved conditions for producing stereo effect to facilitate viewing of stereo images. ^ 1 cl, 20 dwg, 2 tbl |
