Abstract
Applications of high resolution videos have great potential for H.264/AVC. However, due to the multi-frame motion estimation and large search range (SR) requirement, the ultra high system bandwidth becomes the challenge for the plateform based video codec. In this paper, a hybrid-mode embedded compression (EC) is proposed. Two different strategies are respectively used to compress the reconstructed macroblocks (MBs) of intra- and intermode. Up-to 9.2 times of compression ratio (CR) can be achieved even with lossless-compression constraint. Besides, with resource sharing, this system can be integrated into H.264/AVC codec with almost no area overhead. According to the simulation results, the system bandwidth can be reduced by 66.2% and 75.3% in average for high and median quality situation.
