Interruption time reduction methods by predicting data reception for steaming delivery on hybrid broadcasting environments

Due to the recent development of information technologies, streaming delivery on hybrid broadcasting environments has become popular. Hybrid broadcasting environments consist of broadcasting systems and communication systems such as digital TV and Internet. In streaming delivery on hybrid broadcasting environments, clients receive streaming data such as video or audio from both systems and play them while receiving the data. Since interruptions occur when the time to receive data is later than the time to play them, many methods to reduce interruption time have been proposed. However, these methods broadcast the whole data although clients can receive some parts of them from the communication system. Therefore, the broadcast cycle lengthens and these methods cannot reduce the interruption time effectively. In this paper, we propose interruption time reduction methods for streaming delivery on hybrid broadcasting environments. Our proposed methods predict data reception from the communication system and eliminate the predicted data from the broadcast schedule. The broadcast cycle shortens and the interruption time can be reduced further than the conventional methods.
