Abstract
A method of decoding an incoming audio/video stream received by a decoder box that is connected to audio playback equipment and to video playback equipment, the method comprising the steps of evaluating an audio latency and a video latency; if the audio (or respectively video) latency is greater than the video (or resp. audio) latency, testing a first condition to ensure that the time difference (Δt_a, Δt_v) between the presentation time stamp of the audio (or resp. video) samples and the reference clock signal is sufficient, and if the first condition is satisfied, acting, when decoding the audio (or resp. video), to decrease the presentation time stamp of the audio (or resp. video) samples in order to advance playback of the audio (or resp. video) samples, thereby compensating at least in part the latency difference between the audio (or resp. video) latency and the video (or resp. audio) latency.
