ABSTRACT:
A system and related multiplexers/demultiplexers for the transmission/reception of digital television information (video+audio), including high definition information (HDTV). Such transmission typically occurs in packets at various work speeds including, among others, a special transmission in which two data flows are transmitted simultaneously to obtain a single information. The multiplexer is associated with 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.
