MULTIPLEXER OF DIGITAL INFORMATION PACKETS, ESPECIALLY FOR DIGITAL TELEVISION

摘要

A device including a plurality of packetising modules supplying packet memories (PMi) from digital input streams, and multiplexing means (14) for selecting the packet memories from which the multiplex packets are to be retrieved and transferring them sequentially to a device output. Each packet in a packet memory is combined with selection parameters calculated by its packetising module and indicating at least an earliest time, a latest time and preferably an ideal time for transmission of the packet by the multiplexing means. The multiplexing means select the memory from which each multiplex packet is to be retrieved on the basis of the packet transmission time and the respective selection parameters combined with the first packets on stand-by in each of the packet memories.
