Abstract: Real-time streaming and real-time streaming protocols are illustrated in this paper. Due to the special characteristics of real-time streaming media client player based on real-time protocols, this paper presents the model of a streaming media client used in video-on-demand systems. A strategy of flow control, a new policy of packet composing algorithm and a buffer management method are presented. Experimental results show good resource utilization, real-time property, fault tolerance capability and stream synchronization.
