Abstract
With the increased desire of TV consumers for interactivity and personalization, IPTV has been rapidly spread in recent years. IPTV can provide a variety of services through hundreds of channels, but the explosion of TV channels makes users even more difficult to find their desired contents. In addition, the channel zapping delay of IPTV is serious due to the limited network bandwidth. To resolve these problems, this paper distinguishes hot and cold channels by exploiting the real-time viewing rate as well as each user's viewing history, and then, maintains hot channels in the hot list, which is searched first during channel navigation and also prefetched to support the preview of channels. Experimental results show that the proposed scheme improves the IPTV channel seek time significantly compared to existing channel seeking interfaces.
