Hybrid Broadcasting System for Webcast

Due to the recent popularization of hybrid webcast environments, streaming delivery using broadcast and telecommunication is attracting great attention. In streaming delivery on the hybrid broadcasting environment, clients concurrently receive streaming data such as music or movies from both broadcasting and telecommunication systems. Although these systems compensate for the demerits of each other, the waiting time is lengthened if the system does not deliver the data efficiently. To reduce this waiting time, many researches have been proposed scheduling methods. However, since most scheduling methods use a computer simulation, they do not show clearly the effectiveness. In this paper, we implement a hybrid broadcasting system to solve the problem in the conventional methods. In our proposed system, we evaluate the effectiveness for reducing the waiting time using scheduling methods.
