<p>During the reproduction of optical discs, a data stream (IDMA) is generated at a specific, first instantaneous data rate. Further processing of the useful information stored is effected at a second instantaneous data rate, which does not have to correspond to the first data rate. In order to compensate for the resultant difference, a track buffer (TB) is inserted into the data stream coming from the pick-up. However, each decoder (VIDM,AUDM,DATM) connected to this buffer requires a dedicated bit buffer for its partial data stream to be decoded. It is possible to avoid corresponding recopying of the data in the track buffer (TB) if the data written to the track buffer are processed directly by the decoders by means of a chained list. This chained list is generated by a software demultiplexer (SMUX). <IMAGE></p> |
