Due to the limited bandwidth of the mobile network, mobile IPTV does not broadcast the content of all channels to its users. The channel zapping time, which is inevitable time until the user watches the display of the selected channel when the selected channel is not available at the mobile device, significantly affects the QoS (Quality of Service) of mobile IPTV services. This paper presents a simple but effective adaptive channel control scheme that reduces channel zapping time and improves user perceived QoS in the mobile networks. The proposed scheme controls a user behavior-based channel setup of a prebuffering channel and video quality adaptation. The experimental result shows that the proposed scheme can significantly reduce channel zapping time.
