Gao Yu-zhi

Abstract

This system realized the IP-based video network terminal system by choosing multimedia digital chip TMS320DM6446 as the CPU,and using the latest video coding standard H.264 compression algorithm.The paper described in detail the hardware architecture of the TMS320DM6446,design of system hardware and core modules,analysis of system design and key technical difficulties.Experimental results showed that the system can meet the requirements that under D1 resolution video image capture,real-time encoding and transmission without lowering the quality of the video.The system has high performance,strong integration,nicer interactive,and fully reflect the high-performance technical features of multimedia technology.
