A Scheduling Method for Switching Playback Speed in Selective Contents Broadcasting

In selective contents broadcasting, i.e. watching contents users selected themselves, the server can deliver several contents to many users. However, when users watch the data continuously, waiting time occurs by decreasing the available bandwidth and increasing the number of contents. Therefore, many researchers have proposed scheduling methods to reduce the waiting time. Although the conventional method reduces waiting time by producing the broadcast schedule in fast-forwarding, that for playing contents in normal playback becomes lengthened. In this paper, we propose a scheduling method for switching the playback speed in selective contents broadcasting. Our proposed method can make the broadcast schedule based on the configuration of the program and the available bandwidth. In addition, waiting time can be reduced by dividing each content into two types of data for fast-forwarding and normal playback and scheduling them.
