High Efficiency Video Encoding Optimization on DM642

igital video encoding plays an important role in many applications such as digital video surveillance and video conference systems. This paper describes the optimization techniques for H.264 encoder on TMS320DM642 DSP. After indicating the key prob- lems about the real- time realization of the encoder, the paper introduces different optimization ways for different parts of the encoder. The experiment results show the proposed encoder can be applied in real- time video surveillance while preserving good image quality and compression efficiency.
