The purpose of this paper is to reduce the waiting time on webcast for selective contents, by proposing a scheduling method called the “contents prefetched broadcasting considering user participation” (CPB‐CP) method.
The authors analyze and evaluate the performance of the proposed CPB‐CP method.
It is confirmed that the proposed method gives shorter average waiting time than the conventional methods.
A future direction of this study will involve making a scheduling method in the case where the playing time of each content item is different.
In selective contents delivery, users may wait for the next bit of content to start playing after watching the previous one. In quiz programs, users may wait to receive the content data for their selected answer after they select their answer.
In the CPB‐CP method, when a provider node pulls out of the network while delivering contents, waiting time is reduced effectively by reconstructing a delivery schedule that considers the available bandwidth of each provider node.
