A device for transmitting and decoding audio-visual streams arranged in accordance with standard ISO/IEC 11172 is provided. The device (DEC) comprises: interfaces (CSC, IA, CIS) for connection to a local storage device (MEL) or to a telecommunications network (2, 3), for receiving streams from remote sources or send streams to remote receivers; demultiplexing and synchronisation means (DES) for splitting the audio-visual streams into constituent audio, video and private data streams and extracting synchronisation information from the streams, and means (DA, DV, UA, UV) for decoding audio and video streams and present audio and video signals in analog form at the output. A controller (CNT) is to control and supervise demultiplexing and decoding operations.
