Abstract: Due to recent advances in network and multimedia technologies,Video-on-Demand (VoD) has been Paid more and moreattention .In this paper. by giving the definition of the data retrieval cycle time, the client allocated time will be discussed. And then weprovide a dynamic scheduling algorithm for buffer allocation and data prefetching based on user's consume rate. Furthermore, a dateretrieval function will be proposed, which can be compatible with all kinds of VoD data retrieval Operation,such as VCR.
