A Cost-Effective Periodic Broadcast Scheme for Scalable Dissemination of Popular Videos

By Simon Sheu, Wallapak Tavanapong and Kien A. Hua


Recent years have seen intensive investigations of Periodic Broadcast, an attractive approach for scalable dissemination of popular videos. Periodic broadcast guarantees a small maximum service latency regardless of the number of concurrent clients. In this approach, the video server broadcasts segments of a popular video periodically on a number of communication channels. A large number of clients can be served simultaneously by tuning into these channels to receive the video segments. The playback can begin as soon as the first segment arrives. In this paper, we present our novel periodic broadcast scheme called Striping Broadcast. It is designed to offer a low maximum service latency with a very low system cost, making the technique very cost-effective for practical deployment. Our performance analyses demonstrate that Striping Broadcast reaches its design goals as well as utilizes a significantly less server bandwidth compared to Skyscraper Broadcast
