Abstract

Abstract

A low bit-rate real time video encoding system on MPEG using DSP TMS320DM642 as core processor is designed. The main features are: Diamond Search is integrated with Center-based Three-step Search (CTSS); A new method for pre-determination of all-zero blocks is proposed; The encoder is specially optimized for DSP. Experimental results show that the search method in this paper is better than CTSS. The pre-determination of all-zero blocks reduces operation and bit rate efficiently with little image quality decrease.
