Zusammenfassung: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.
