Research on integrated model and transmission controlling algorithm for distributed multimedia information system

  • To resolve the synchronization for multimedia communication and multimedia presentation of distributed multimedia system, a distributed multimedia information system integrated model(DMISIM) was put forward. In this model, distributed multimedia information system was formulated as synchronization interval units(SIU), communication channels and a mapping from the channels to the SIUs sequence. DMISIM describes not only the static attributes of multimedia information and communication channel but also the dynamic processes of multimedia communication transmission. Based on DMISIM, distributed multimedia communication transmission mechanism was researched and minimum deviation scheduling algorithm(MDSA) was described as the improvement of classic list scheduling heuristic(CLSH). It is proved by theoretical analysis and logical deduction, that MDSA has better performance than that of CLSH in such fields as channel usage factor, capacity requirement of destination buffers, whereas the algorithm complexity and multimedia synchronization quality are stable. MDSA is independent of communication subnet transport mechanism and can be widely used in multimedia communications.
