QoS adaptation in media synchronization using delay compensation and smoothing technique

Synchronization and continuity are essential for multimedia presentation, but because network resources and available bandwidth are both limited, synchronization quality and continuity quality have to be traded off in response to the fluctuating network conditions. This paper therefore introduces an algorithm for intramedia synchronization with quality of service (QoS) adaptability. The work described here is an extension of our earlier proposal of a synchronization algorithm by delay compensation protocol. That algorithm has been extended by the introduction of QoS control mechanisms in the QoS plane of a distributed control platform. The extended approach results not only in better synchronization and continuity, but also integrates the QoS adjustment into the existing architecture. Simulations implemented on a UDP/IP network have verified the effectiveness of the proposed scheme
