The C-MAC/packet system for satellite broadcasting

The European Broadcasting Union (EBU) has recommended the C-MAC/packet system as a European standard for direct broadcast satellite (DBS) TV. The system is based on a time multiplex of compressed analogue vision components and digital sound and data within each line period of the broadcast signal. The paper describes the structure of the signal, outlines the service identification and conditional access systems and gives the performance in a satellite channel.
