Due to the recent popularization of the Internet, continuous media data broadcasting such as audio or video have attracted great attention. Although continuous media data broadcasting can reduce the more necessary bandwidth than conventional on-demand delivery, waiting time from requesting data to playing it increases. To reduce this waiting time, a division based broadcasting that separates data into several parts and delivers them has been proposed. In division based broadcasting, many researches have been proposed scheduling methods to reduce waiting time. However, since most scheduling methods use a computer simulation, they do not show clearly the effectiveness. In this paper, we implement a division based broadcasting system to solve the problem in the conventional system. In our proposed system, we evaluate the effectiveness for reducing the waiting time using several scheduling methods.

“…We have been proposed a division based broadcasting system "d-Cast" [1], which can evaluate scheduling methods in network environments. However, d-Cast does not consider the case where clients start receiving several types of data concurrently using several channels.…”

“…• Methods that use broadcasting By making a broadcast schedule which can simultaneously finish receiving the next piece of partitioned data when it has finished playing the present piece of partitioned data, the interruption time can be reduced [1], [2]. By using broadcasting, data can be concurrently delivered to several playback nodes and the server load can be reduced.…”

Due to the continued popularization of broadcast and communications integration environments, streaming delivery using broadcast and communication is attracting attention. In streaming delivery on the environment, clients concurrently receive streaming data such as music or movies from broadcasting and communication systems. Although these systems compensate for the demerits of each other, the interruption time is lengthened if the system does not deliver the data efficiently. In our proposed method, the system produces a broadcast schedule of streaming data that considers communication bandwidth. In this research, we confirmed that extra bandwidth that gives shorter interruption time differs from communication bandwidth. Our proposed method reduces the interruption time by finding the extra bandwidth.

Due to the continued popularization of broadcast and communications integration environments, streaming de livery using broadcast and communication is attracting great attention. In streaming delivery on an environment, clients concurrently receive such data as music or movies from both broadcasting and communication systems. Although conventional methods reduce the interruption time, they fail to consider the upper limit in the available bandwidth. In this paper, we propose a delivery method that reduces the interruption time by considering the number of clients. Our proposed method reduces the interruption time by setting the bandwidths of the broadcast and communication systems and making a delivery schedule.
