Method of decoding an incoming audio/video stream

A decoding method for decoding an incoming audio/video stream received by a decoder box that is connected to audio playback equipment and to video playback equipment, the incoming audio/video stream transporting a reference clock signal and comprising audio samples and video samples including respective presentation time stamps, the decoding method comprising the steps of:

• evaluating an audio latency introduced by an audio path and a video latency introduced by a video path;
• 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 to enable the audio (or resp. video) samples to be decoded correctly, 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 (Δlat_a, Δlat_v) between the audio (or resp. video) latency and the video (or resp. audio) latency.
