An Efficient Streaming Service Adaptation On Mobile Devices

The Internet mobile streaming service at the server side particularly for the recent Internet mobile streaming delivery is investigated. H.264 is an industry standard for video compression, the process of converting digital video into a format that takes up less capacity when it is stored or transmitted. The H.264 standard provides advanced algorithms for motion estimation, interprediction, spatial intra prediction and transforms. The H.264 standard is detecting a user‘s bandwidth capability in real time and then adjusting the quality of the video stream accordingly. This results in less buffering, fast start times and overall better experience for both high-speed and low-speed connections. Perhaps the biggest advantage of H.264 over previous standards is its compression performance. Compared with standards such as MPEG-2 and MPEG-4 Visual, H.264 can deliver, Better image quality at the same compressed bit rate, or A lower compressed bitrates for the same image quality
