Abstract: 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.

Abstract: 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.

Abstract: The present invention relates to a communication device, comprising modulation and demodulation means, connected to a communication network and to at least one receiver/decoder, comprising means of selecting among the following different possibilities, depending on the available bandwidth on the communication network, upon receipt of a request originating from said receiver/decoder: transmit the request unmodified to said network; or modify the request in order to request a feed of lesser quality; or refuse to transmit the request to said network and broadcast to the receiver/decoder a preconfigured multimedia file. The present invention also relates to a communication method.
