Video-on-Demand is undoubtedly a promising technology for many important applications. Several periodic broadcast techniques have been proposed for the cost-effective implementation of such systems. However, there is a server delay for all of them. To address the shortcoming, we present a new scheme improving the staggered broadcasting by jointly using prefix caching scheme of VOD system in P2P environments. In thins paper, each client plays a role in the first segment staggered broadcasting server to serve the prefix stream to other clients that request the same video stream. The buffer can be empty after the client has served the following client. As a result, we are able to achieve no service latency time and the low buffer space.
