    Abstract: PROBLEM TO BE SOLVED: To provide a synchronizing method suitable for reproducing an audio frame and/or a video frame. SOLUTION: The method for synchronizing reproduction of the audio frame and/or the video frame comprises detecting a reproduction time stamp (PTS) in a stream of frames. A reproduction time (t(PTS)) indicated by the time stamp is compared with a time (t(IPCR)) indicated by a local reference clock (2). In accordance with a variant value (V) of a deviation value between the reproduction time and the corresponding time indicated by the clock and a means value (M) of the variant value, the clock is initialized according to the reproduction time indicated by the time stamp (107) or the reproduction of frames is regulated (109, 110).
