Abstract
H.264/AVC is a standard for video compression developed by the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC JTC1 Moving Picture Experts Group (MPEG). However, the computational complexity of H.264/AVC contributed a lot to the delay time of multi-screen sharing system. In this paper, the motion estimation algorithms provided in X264 have been analysed, and an optimized algorithm has been proposed, this optimized algorithm can reduce a lot of unnecessary computation. And more, this paper designed and implemented the multi-screen sharing system with the improved encoder. Experimental results show that the proposed method has increased the encoding speed and decreased the delay time, while incurring little, if any, loss in quality.
