Abstract:
Recent proliferation of portable devices requires video contents playable on virtually any portable devices. However, their limited computing resources pose significant restriction to accomplish real-time decoding of high resolution or high quality video contents. To solve the problem, we propose a complexity scalable video decoding scheme for real-time playback on portable devices. In this paper, we analyze the complexity of H.264/AVC video decoding elements and develop a complexity scalable decoding scheme by simplifying motion compensation and deblocking filtering. Experimental results with the H.264/AVC main profile coded bitstream show that its decoding complexity can be reduced up to 26% without significant loss in subjective quality as compared to the conventional H.264/AVC decoder.
