Abstract

This paper describes in detail the various low level optimization techniques for implementing the H.264/AVC video encoding on the TI TMS320DM642 DSP platform. Optimization speedup performance of 5.25 times faster is achieved. A complete AVC encoding and RTSP streaming server system is also developed on the same platform, which is capable of serving live 4CIF video streaming at 25 fps with approximately 500 ~ 1500 kbps for an application in remote IP-based video surveillance.
