Abstract

In this paper, we propose client buffer stabilizing algorithm which guarantees synchronization and media continuity against variability of media data and network load in the distributed multimedia environments. The proposed algorithm stabilizes the client buffer by transfering control information messages, which includes the control volume and the control time of media stream calculated on the basis of the current status of a client, to a multimedia server. The client predicts the receiver's resources and network status along with a pre-determined period, and generates control messages whenever overruns or starvations are expected to occur. The values of control messages are calculated by the status of client, the media stream transfer mechanism of multimedia server, and the status of the network. The characteristics of the proposed algorithm are proventing the low quality of media streams when it is dropped excessively and stabilizing the multimedia system when the variability of network loads is high.
