A real-time video deinterlacing scheme for MPEG-2 to AVS transcoding

Real-time motion compensated (MC) deinterlacing is defined to be deinterlacing at the decoder in real-time at low cost using the transmitted motion vectors. Although the possibility of this was shown ten years ago, unfortunately few such studies have been reported so far. The major difficulty is that motion vectors derived from video decoders, which generally refer to average motion over several field periods instead of motion between adjacent fields, are far from perfect. In this paper, a real-time MC deinterlacing scheme is proposed for transcoding from MPEG-2 to AVS, which is the Audio Video coding Standard of China targeting at higher coding efficiency and lower complexity than existing standards for high definition video coding. Experimental results show that the presented scheme is more insensitive to incorrect motion vectors than conventional algorithms.
