N2 - Due to the recent popularization of digital TV broadcasting systems, continuous media data broadcasting is attracting much attention. In general broadcasting systems, although the server can repetitively broadcast the same data to many clients, they have to wait until they have received all of the data to play them. Many researchers have proposed a division-based broadcasting technique with which the server can reduce the waiting time by dividing the data into several segments and frequently broadcasting precedent segments. When the server delivers highly popular movie data to many clients, the number of simultaneous watchers obviously increases compared with less popular movie data. Therefore, by dynamically updating the available bandwidth and the delivery schedule, the server can reduce the interruption time of movie data. A conventional scheduling method, which dynamically updates the allocation of bandwidth and channel without interruption while playing movie data, has also been proposed. Although this scheduling method has been evaluated in a simulation environment, it has not been evaluated with an effective division-based broadcasting system considering dynamic updates of a delivery schedule in actual network environments. In this paper, we propose a division-based broadcasting system considering the dynamic updates of a delivery schedule. In our proposed system, we design and implement a function that updates the delivery schedule without interruption and evaluate the effectiveness of the scheduling method and the effect of the interruption time in actual networks.
