Abstract
In this paper, we propose a method to realize compound video (multiple videos on a layout)delivery service for mobile terminals. In the proposed method, we introduce proxies which receive multiple videos from corresponding servers and produce a composite video from the received videos in real-time according to the layouts which users specify. However, if users require sets of videos with slightly different layouts, multiple similar composite videos will be generated and the wireless bandwidth will be suppressed to transfer them. So, the proposed method identifies the common part in layouts of user requirements, and transmits to each user a composite video corresponding to the common part and remaining videos. We have developed a greedy algorithm which calculates the set of videos to be transmitted within the available bandwidth, so that the sum of satisfaction degrees of all users is maximized. Through experiments, we confirmed that our method can achieve much higher user satisfaction degrees compared to the case that each user terminal receives multiple videos separately and plays them back in parallel.
