Abstract
The invention relates to a method of generating an optimized contribution signal comprising multiplexes. Each multiplex comprises global broadcasting services and its own combination of regional services. Each multiplex comprises stuffing packets and packets transporting signaling tables. The optimized contribution signal is generated by retaining only the global broadcasting services that are different from one another. The stuffing packets are marked and the packets transporting the signaling tables according to the multiplex to which they belong. Data bursts are constructed from the data streams corresponding to the global broadcasting services, to the regional services and to the marked stuffing packets and to the marked packets transporting the signaling tables. Another subject of the invention is a demultiplexing method, an optimized contribution signal and a regionalized data broadcasting system, and a receiver. More particularly, the invention makes it possible to optimize the bandwidth needed to broadcast, in data bursts, notably via a satellite link, global broadcasting services and regional broadcasting services.
