An experimental time-compression system for satellite television transmission
Abstract
Time compression multiplexing (TCM) is a technique involving the combination of analog signals. The individual waveforms have to be time compressed before they are combined on a single radio channel in a time-division manner. The feasibility has been studied to use this technique for the transmission of multiple high-quality TV signals in a (C-band) satellite transponder of 36-MHz bandwidth. The present investigation is concerned with an experiment which demonstrates the practical feasibility of the proposed technique with field or line differentials to transmit two television signals. The experimental system has been implemented with today's digital technology. The system employs digital processing to convert the video signals into interleaved lines (or fields) of originals companded line (or field) differentials.
