Abstract: A method and device are provided for decoding one or more audio data streams and one or more video data streams obtained from one or more sources. According to the method, portions of the audio data stream and portions of the video data stream are loaded into a set of buffer memories, and audio data and video data are supplied from the buffer memories at the input of at least one audio decoder and of at least one video decoder, respectively. The video data and the audio data are decoded with the aid of the audio decoder and of the video decoder, respectively. The loading is carried out by a management module according to the Pull mode. Alternately or additionally, the supplying is carried out by the management module according to the Push mode. The management module is regulated by the video decoder.

Abstract: A process for decoding and for displaying in rewind mode pictures of a stream of picture data compressed according to the MPEG standard using a specified number N of frame memories each adapted for storing a decoded picture, where N is an integer greater than or equal to 4, applies rules for selecting a frame memory when a frame memory is to be overwritten so as to allow the storage of a new picture to be decoded.

Abstract: A method and device are provided for synchronizing the presentation of audio frames and/or of video frames comprises the detection of presentation time stamps in a stream of frames. The presentation instant indicated by a time stamp is compared with a time delivered by a local reference clock. Depending on a variance and on an average of values of deviation between presentation instants and corresponding times indicated by the clock, the clock can be initialized according to the presentation instant indicated by a time stamp or the presentation of the frames can be adjusted.

Abstract: A process for the decoding and displaying in forward mode at a theoretical speed xN of pictures coded according to the MPEG standard applies decoding and display rules, according to the value of a delay of the pictures displayed with respect to theoretical pictures specified by display at theoretical speed, according to specified thresholds (N1, N2, N3, N4).
