Method, device and system for generating a contribution data stream
Abstract:
A contribution system where the national services are not duplicated in the single stream. This single stream is transmitted in a mode not implementing burst transmission. Advantageously, the single stream is not protected by an FEC error correcting code, as present in the radio broadcast standard, for example DVB-H. Synchronization is provided by the insertion by the concentrator of synchronization packets comprising three synchronization stamps. A first stamp serves to synchronize the deconcentrators with each other and with the concentrator. A second stamp generates a first synchronization signal allowing synchronous generation of the period of the burst transmission mode necessary for generating the regional signal. The third stamp serves to generate a second synchronization signal for generating so-called “MIP” synchronization packets for synchronizing the various modulators.
