Real time video streaming over wireless networks is an increasingly important and attractive service to the mobile users. Video streaming involves a large amount of data to be transmitted in real time, while wireless channel conditions may vary from time to time. It is hard to guarantee a reliable transmission over the wireless network. Bandwidth, packet loss, packet delays, and outage times are the parameters specifying the transmissions. The quality of the video is affected negatively when network packets are lost. The mobile users may notice some sudden stop during the video playing. Some times the picture is momentarily frozen, followed by a jump from one scene to another.
