Abstract
As IPTV has become one of the major Internet services, IPTV users and channels increase rapidly. However, the increased number of channels makes users difficult to find their desired channels. Along with this, the channel switching time of IPTV incurs serious user-perceived delay. To alleviate these problems, this paper presents hybrid schemes that combine channel prefetching and reordering schemes. Simulation experiments show that combining adjacency based prefetching and popular channel reordering reduces the channel seek time by up to 44.7% in comparison with the conventional channel seeking interfaces.
