A Scheduling Method for Selective Contents Broadcasting with Fast-Forwarding

Due to the recent popularization of digital broadcasting systems, selective contents broadcasting depending on viewers' preference, have attracted attention. For example, in a quiz program, a user selects his answer and watches the video content for the answer. When the server deliver programs reflecting users' preferences, clients have to wait until their selected contents start playing. Therefore, we have proposed a scheduling method to reduce the waiting time. However, we have not considered the case that clients play contents with fast-forwarding. In this paper, we propose a method to reduce the waiting time for selective contents broadcasting considering fast-forwarding. In our proposed method, by separating parts for double playing speed and normal playing speed and scheduling the effective schedule, we effectively reduce the waiting time.
