Providing on-demand sports video to mobile devices.

This paper introduces a system for providing on-demand sports video to mobile devices, which has two main contributions. First, we construct an infrastructure for extracting and delivering the highlights instead of the whole sport videos to mobile clients, which can significantly reduce the bandwidth consumption. Second, we design an advanced UI for the mobile clients to effectively browse and interact with the video highlights. To validate the practicality and effectiveness of this system, we conduct the experiments on several real soccer videos. The results demonstrated that more than 65% of bandwidth consumption could be reduced. Moreover, the initial user study results show that the mobile users could interact effectively with the interface to seek or navigate sports videos.
