摘要： The present invention concerns a method for generating a stream from first and second received data streams, the data streams consisting of frames, each frame containing a synchronisation packet, a signalling packet giving information on the structure of the data stream and packets called baseband frames. The method comprises the steps of: -aligning (E54) the two received data streams by bringing the synchronisation packets or the signalling packets of the frames of each data stream into phase, -identifying (E55), in one of the received data streams, baseband packets identifying packets of a first type, -inserting (E56), into each frame of the first received stream, baseband packets of the frame of the second stream of which the synchronisation packet is aligned with the synchronisation packet of the frame of the first stream.

摘要： A device (1.3) is placed upstream of a modulator in a digital service stream broadcasting chain, and is adapted for receiving a plurality of transport streams and for transmitting a transport stream to a modulator, each transport stream encapsulating a digital service stream adapted to be broadcast by the modulator, said digital service streams being representative of one and the same digital service. The device is also adapted for: extracting (2.3; 2.4) digital service streams from the transport streams received; detecting (2.1; 2.2; 2.3; 2.4) errors in the stream; aligning (2.5, 2.6, 2.7) the extracted streams; selecting (2.7) a stream from among the aligned streams, as a function of possible detected errors; encapsulating (2.8) the selected stream, so as to form the transport stream to be transmitted to the modulator.

摘要： The present invention concerns a method for generating a stream compliant with the DVB standard which is understood by a first-generation decoder, typically compliant with DVB-S/C/T/, and which also allows the deterministic generation of a stream compliant with the second-generation DVB-T2 standard. A method is described for generating a stream containing a multiplex compliant with a first-generation DVB standard. Said stream also contains information relating to DVB-T2 compliant encapsulation of at least one sub-set of the broadcast programmes inserted into the stream in the form of private sections which will be ignored by a first-generation decoder, which will decode the stream in compliance with the first-generation standard. A device according to the invention can construct the T2-MI stream in a DVB-T2 transmitter in a deterministic manner, therefore enabling it to integrate into an SFN network.

摘要： In the field of broadcasting digital services to terminals for restoring said services, the problem of synchronisation in the case of a transmission network with a single modulation frequency, and the reliability of the broadcasting channel by equipment redundancy have been of particular interest. The present invention proposes a broadcasting system that comprises a duplicated formatting module. The system allows a modulator to switch between the two flows generated by the two formatting modules without desynchronisation. The formatting modules are synchronised therebetween in order to generate synchronised flows. Accordingly, when a modulator has to switch from a first flow generated by one of the formatting modules to a second flow generated by a second formatting module, the switching can be carried out without requiring a re-synchronisation step. It is thus possible to prevent an incident occurring during the flow generation from systematically resulting in a service interruption due to the modulator re-synchronisation.
