Zapping delay reduction method for sports live with multi-angle on smart TV

Abstract

Recently, social TVs and personalize broadcasting services have taken place on interactive television services. While traditional television services do not support multi camera angles or views on sports live, multiple angle of view services have been studied such as a free view point TV, a panorama TV, and multi-view or multi-angle TV. On the internet-based broadcasting system, users face a zapping delay when they change channel or view. If mobile devices, IPTVs, and PCs are considered for these services, the zapping delay problem is a critical issue for user experience. In this paper, a zapping delay reduction method is proposed using a segmentation method of H.264 standard stream and thumbnails of streams for multi-angle broadcasting systems. Since the proposed system reduces a zapping delay between multi-angles, users have no sense of difference with traditional television services. ？ 2011 ACM.
