Signalling in parity: A brief history
Abstract
Equipment built in British Broadcasting Company (BBC) Engineering Research Department in 1974 for use on an experimental 120 Mbits/s digital link required no additional signalling capacity for multiplex control and synchronization. The general technique of signalling in parity as used in that equipment and how it has found other applications over the last ten years in synchronization, control and robust transmission of auxiliary data are described. The technique features in several new services such as the Radio-Data System (RDS), digital stereo sound for television (DSSTV) and the sound multiplex of the C-MAC/packet system for direct broadcasting by satellite.
