Evaluation on the performance of adaptive playout for the multicast streaming of stored media

A new inter-client synchronization framework employing a server-client coordinated adaptive playout and error control toward the multicast streaming of stored media is discussed in this paper. Based on the overall synchronization status as well as the buffer occupancy level, the playout speed of each client is manipulated within a perceptually tolerable range. By coordinating the playout speed of each client, the inter-client synchronization with respect to the target presentation time is smoothly achieved. The cumulative feedback for retransmission assisted by both playout speed manipulation at clients and implicit help of a streaming server is also conducted to increase the reliability. Simulation results demonstrate the performance of the proposed multicast streaming framework.
