Abstract: This paper studies the Integrated Performance Primitives(IPP) library for multimedia processing and the MPEG-4 CODEC technology, proposes a method of MPEG-4 CODEC using IPP library, in the background of real-time video processing in embedded system. A MPEG-4 video transmission system based on Intel PXA255 in the wireless network environment is designed and implemented. It is a valuable solution to real-time multimedia processing in embedded system. Experimental results show that the method is effective.

Key words: embedded system, MPEG-4 CODEC, real-time multimedia processing
