Abstract :
Due to the recent popularization of digital broadcasting systems, selective contents broadcasting depending on viewers´ preference have attracted great attention. For example, a user selects his answer and watches the video content for the answer in a quiz program. The conventional methods reduce the waiting time by producing an effective broadcast schedule. Although the server can deliver programs that meet users´ preferences, clients have to wait until their selected contents are delivered. In this paper, we propose a method to reduce the waiting time on selective contents delivery with node relay based webcast that relay data among nodes. Our proposed method reduces the waiting time by scheduling contents considering available bandwidth of each nodes.
