A Scheduling Method for Division Based Broadcasting of Multiple Video Considering Data Size

When watching videos, many people receive the data by broadcasting. In general broadcasting systems, even though servers can concurrently deliver data to many clients, they must wait until the first portion of the data is broadcast. To reduce the waiting time, many studies employ the division based broadcasting technique, which reduces waiting time by dividing the data into several segments and frequently broadcasting the precedent segments. In division based broadcasting, although several researchers have proposed scheduling methods to reduce the waiting time for delivering multiple video, they failed to consider cases where the data size of each video is not the same. In this paper, we propose a scheduling method for division based broadcasting of multiple video that considers their data size. Our proposed method divides the data and produces an effective broadcasting schedule based on the data size of each video. In addition, the server can reduce the required bandwidth for delivering multiple video.
