摘要： A solution for delivery of audiovisual content to a receiver device is provided. At the transmitter side, a transmission buffer is constituted, while offering fast channel change and fast trick modes at the receiver side. At least one GoP, starting with a first I-frame is sought in the content that is to be transmitted. The timing references of the data in the at least one GoP that is prepared for delivery to a receiver device are modified so that the data is decoded by the receiver at a slowed-down rate for a given duration. This creates a lag between reading of data in by the transmitter and decoding of data by the receiver. The lag is used by the transmitter to fill the transmission buffer, while the receiver does not have to wait for the transmission buffer to be filled to start decoding.

摘要： A method for accelerating channel changes from a previous channel to a new channel in a video decoding device is proposed. A salient idea is to monitor the time intervals between channel change events so as to detect when a user is looking forward quickly browsing a set of TV channels. The disclosed method comprises at least two operation modes : a normal operation mode and a burst operation mode. In case the time between two consecutive channel change events is below a first value, the disclosed method comprises operating the channel change into a burst operation mode, wherein operating the channel change in a burst operation mode comprises only a subset of the features comprised in operating the channel change in a normal operation mode.

摘要： Flooding audio/video descramblers with scrambled elementary data is avoided when the control access module did not yet have the time to decipher the descrambling keys required for the descrambling. Elementary stream data belonging to the current key period are temporary stored (cached) in a memory if the control access module is not ready to receive new descrambling keys to decipher and injection is postponed to the moment when the control access module is ready and if the cached data still belongs to the current key period. This way, it is ensured that every allowed program elementary stream data are descrambled.

摘要： In a video delivery environment where a channel change in an audio/video receiver starts with a burst delivery of an audio/video stream to the receiver, characteristics of the audio/video stream are determined such as audio-video drift and burst characteristics in terms of duration of excess data delivery. At least one of these characteristics determines an offset to add to an initialization of a decoder clock, so that moving images are shown as early as possible after receipt of the channel change command, to be joined by lip synchronized audio before burst end.

摘要： In order to optimize cache memory management, the invention proposes a method and corresponding apparatus that comprises application of different cache memory management policies according to data origin and possibly to data type and the use of increasing levels of exclusion from adding to cache of data, the exclusion levels being increasingly restrictive with regard to adding data to cache as the cache memory fill level increases. The method and device allows among others to keep important information in cache memory and reduce time spent in swapping information in- and out of cache memory.
