| Abstract: | H. 264 is the newest video compression standard jointly published by ISO/IEC and ITU - T, it will be applied widely in digital video communication field. This paper introduces the optimization ideas and describes some optimization techniques to realize real - time encoder on TMS320DM642 chip. Some corresponding experiments have been performed on the un - optimized encoder and the optimized encoder and the results are presented and analysed. |
