System and multiplexer/ demultiplexer for the transmission/ reception of digital television information

摘要

It is described a system and related multiplexers/demultiplexers for the transmission/reception of digital television information (video + audio), included the high definition information (HDTV), in which it is used the transmission in packets and various work speeds are foreseen, among which a special transmission that uses two data flows transmitted contemporaneously for getting a sole information. The multiplexer is associated to external buffers that receive the data at different speeds, form the packet and generate requests of transmission to the multiplexer that receives them according to preestablished priorities.
