Parallel Design and Implementation of Block Mode Selection in Motion Estimation of H.264
Liao Yong-hong · 2008
To facilitate H.264/AVC implement in the application system with high low rate,its coding algorithm needs to be optimized.This paper first analyzes the H.264/AVC encoder deeply,then on the basis of it presents the parallel design program of block mode selection and parallel designs and implements this program.Finally the design program is tested on multi-core server and the testing results show that the encoding speed of the three-step search algorithm after parallel improves by an average of 2.73 times without affecting the quality of H.264 coding.
