A Fast Video Decoding Technique by Means of Converting Input Video Stream into Forward-Oriented Format Stream in Little-Endian Systems

Video decoding is a must-have feature in modern electronic devices in consumer market. A real-time processing demand is crucial in H.264 video application. In this paper, we present a fast H.264 video decoding technology based on a fast and quick bit pattern extraction method in video stream that is coded with variable-length code stored in little-endian systems. The Key of our approach is to make the video stream encoded as a decoding friendly formatted stream. In addition, we present a very quick converting method based on LUT(Look-up Table) technique. The experimental results show that about 11.45% reduction in bit pattern extraction time.
