Fast channel zapping scheme for IPTV on ACR
ACR下的IPTV频道快速切换方法

This paper presented an improved method based on large-scale access convergence routerACR with thinking both the character of ACR network and channel change process of IPTV, which reduced the zapping delay and advance the QOE. By dealing with zapping processes at one time, the new method had the sum of all parts of delay shortened. The distribution curves of some key parameters by simulation show that the proposed method achieves the shorter channel zapping time compared with traditional method, and without increasing bandwidth consumption and complication of network equipments.
