Design and Optimization of Video Compression System Based on MPEG-4
This paper introduces a new method of video-compress based on MPEG-4. The coding algorithm adopts 3-D wavelet transformation and Shape Coding. In hardware implement, DSP chips and FPGA chips is adopted, FPGA completes the task of multiply clock periods operate, while DSP chips accomplishes the function of both the single clock period operate and the control of FPGA relocated calculation. Experimental result indicates the design can improve coding efficiency and get a good tradeoff between bit-rate and distortion. The method is shown to be simple, efficient and suitable for hardware implementation.
