<p>The invention relates to a device for demultiplexing coded data corresponding to multimedia objects. The data are organized in a bitstream divided into individually accessible portions - for instance Access Units for an MPEG-4 compliant bitstream - themselves subdivided into smaller data entities - SL-packets in the cited example - which all the demultiplexing operations are applied to. Said operations are mainly, for all the data received at the input of the demultiplexing device: reading and formatting of a buffer, extraction of successive Access Unit segments, progressive reconstruction of a complete Access Unit, transmission of said Access Unit to an output buffer or file.</p> |
