Abstract :
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.
