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.

System for broadcasting video programmes

The present invention relates to the field of video stream transport. The invention specifically relates to a method for generating a clock signal controlling the transmission rate of an output signal device transmitting a stream from an input stream. The invention describes a method for generating the clock of the output stream from a measurement of the clock of the input stream. Said measurement is permanently adjusted in order to increase the accuracy of the measurement as well as to monitor possible drifts of the input stream clock. Said decorrelation between the clock of the input stream generates a regular output clock, even when the clock of the input stream is irregular.
