Abstract

To satisfy the requirement of embedded video encoder in various scenarios, an embedded universal video coding system based on embedded processors is proposed in this paper, which combines the advantages of multi processors in single architecture. According to different channels, two feasible solutions are given to avoid the overflow and underflow of buffer while transmitting the compressed data. Due to limited computational resources and real-time application requirement, each module of the MPEG-4 codec is reviewed and efficiently implemented based on the embedded hardware platform. Experimental results show that the embedded system can successfully be used for real-time application.
