Abstract:
1. A digital multimedia network with latency control comprising: apparatuses for processing of isochronous data streams, wherein a borderline input apparatus providing a data stream generates a latency time stamp which contains an absolute time indicating a creation time of said isochronous data streams and an accumulated delay time which is updated by each apparatus processing said isochronous data streams, wherein said latency time stamp of said isochronous data stream is evaluated by a borderline output apparatus of said network which synchronizes said isochronous data stream by delaying said isochronous data streams depending on their evaluated time stamps, wherein said isochronous data stream comprises data sequences each having a sequence-ID which indicates a source apparatus which provides said data sequence, wherein each data sequence further comprises a single or multi sequence marker which indicates whether the corresponding data sequence is a single data sequence provided by a single source apparatus or a multi data sequence provided by multiple source apparatuses, and wherein the processing apparatus comprises a mixing apparatus which delays all received data sequences to be mixed to match the slowest received data sequence according to the accumulated delay times of the respective data sequences and mixes then the received data sequences to generate a mixed data sequence.
