摘要： A method for processing a channel change request in a television system operating according to the IP protocol. This method is implemented in a digital decoder of the subscriber and its purpose is to avoid overloading the access network in the case of burst zapping and avoid penalizing the reactivity time of the system in the case of simple zapping. In the case of reception of a burst of channel change requests separated by a time interval less than the duration of the predetermined timeout (Ttempo), the digital decoder transmits, to the access network of the system, two physical channel change requests, one for the first channel change request and the other for the last channel change request of the burst.

摘要： The present invention relates to a method for processing a channel change request in a television system operating according to the IP protocol. This method is implemented in a digital decoder of the subscriber and its purpose is to avoid overloading the access network in the case of burst zapping and avoid penalising the reactivity time of the system in the case of simple zapping. According to the invention, in the case of reception of a burst of channel change requests separated by a time interval less than the duration of the predetermined timeout (Ttempo), the digital decoder transmits, to the access network of the system, two physical channel change requests, one for the first channel change request and the other for the last channel change request of the burst. The first request is transmitted immediately after the reception of the first channel change request and the last request is transmitted with a delay equal to the duration of the timeout after the reception of the last channel change request. In the case of simple zapping, the digital decoder transmits immediately after reception of the channel change request a physical channel change request.

摘要： 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.
