METHOD FOR SHAPING DUAL-CHANNEL AUDIO SIGNALS INCLUDING STEREO ONES, BROADCASTING SIGNALS, CONTROL DATA AND COMMANDS IN SOUND DIFFUSION AND CABLE NETWORKS (ALTERNATIVES); MULTICHANNEL AUDIO SIGNAL TRANSMISSION, BROADCASTING, CONTROL DATA AND COMMAND TRANSMISSION SYSTEM IN SOUND DIFFUSION AND CABLE NETWORKS Russian patent published in 2001 - IPC

FIELD: radio engineering. SUBSTANCE: novelty in transmitting television-program audio signals using SECAM system over existing radio channels jointly with computer data or translation signals and broadcasting signals is that audio signals are coded using MUSICAM system . Chosen data-transmission format is used in multiplexing coded signals, data interlacing is introduced for digital error protection of burst, noise-protected digital audio data stream is modulated by four-position phase keying of carrier. EFFECT: improved quality of television-program audio signals. 3 cl, 2 dwg
