Digital sound service for direct broadcasting satellites
Abstract
A 16 channel (4 phase (CPSK), or 12 channel (2 phase CPSK) digital sound link for the TV Sat satellite is proposed. Small parabolic antennas suitable for sound and TV broadcasts assure reception. A specially developed tuner allows the user to select either a given program from 1 of 16, or 1 of 8 types of program, e.g., sport or opera. Tests with OTS satellite and a cable distribution network prove the feasibility of the proposal. Encoding, transmission, signal modulation and links are outlined. Equipment is described.
