Abstract: In embedded multimedia applications, improving video quality under constraints of bandwidth and storage is an important problem. In this paper, we discuss the relationship among picture resolution, quantization precision and subjective quality in video coding for embedded systems. Then we propose a principle of tradeoff between picture resolution and quantization precision. Video coding based on the tradeoff principle can achieve higher subjective quality at low bitrates, and significantly reduce the burden of decoders. Experimental results on both MPEG-2 codec and H.264 codec prove that the tradeoff principle is valuable and feasible for embedded systems.
