Abstract

In this paper, we present a novel framework that serves adaptive sports video to mobile users. Our framework combines content-based sports highlights extraction and quality-domain video compression technologies in video server, capable of reducing wireless bandwidth consumption more effectively. We develop a robust replay-based highlights extraction method, and propose a content-based video streaming coding scheme to handle the problems of bandwidth and capacity of computation. To validate the practicality and effectiveness of our system, we conduct the experiments on several real soccer videos. The experimental results demonstrate the robustness of our highlights extraction method and more than 77.5% of the bandwidth consumption could be reduced.
