Fast IPTV Channel Switching Using Hot-View and Personalized Channel Preload Over IEEE 802.16e

The Internet Protocol TeleVision (IPTV) is emerging as one of the most promising applications over next generation networks. The recently released IEEE 802.16d/e is capable of ensuring high bandwidths and low latency, making it suitable for delivering multimedia services. In addition, it also provides wide area coverage, mobility support, and non-line-of-sight operation. In this paper, the authors deliver IPTV streaming over 802.16 wireless systems and propose a simple but effective IPTV channel-switching algorithm to keep the channel zapping time in a tolerable range. In addition, they discuss how to allocate channels in the limited bandwidth over wireless networks, such as 802.16. The proposed algorithm is based on hot-view channel and personal favorite channel preloading to reduce the network delay and achieve the goal of fast channel switching.
