A method for generating a stream from first and second data streams received, the data streams comprising frames, each frame containing a synchronization packet, a signaling packet giving information on the structure of the data stream and packets referred to as baseband frames. The method comprises the steps of aligning the two data streams received by putting in phase the synchronization packets or the signaling packets of the frames of each data stream, identifying, in one of the data streams received, baseband packets identifying packets of a first type, and inserting, in each frame of the first stream received, baseband packets of the frame of the second stream the synchronization packet of which is aligned with the synchronization packet of the frame of the first stream.

Method for generating and transferring at least one data stream

The present invention concerns a method for generating a stream in accordance with the DVB standard that is understood by a first-generation decoder, typically in accordance with DVB-S/C/T/, and which also enables the deterministic generation of a stream in accordance with the second-generation DVB-T2 standard. A method is described for generating a stream containing a multiplex according to a first-generation DVB standard. This stream also contains the information relating to an encapsulation in accordance with DVB-T2 of at least one subset of broadcast programs inserted in the stream in the form of private sections that will be ignored by a first-generation decoder that will decode the stream in accordance with the first-generation standard. Equipment according to the invention can construct the T2-MI stream at a DVB-T2 transmitter deterministically, which can then be integrated in an SFN network.
