Abstract: In wireless multimedia applications, low bitrate video takes an important part. However, its poor subjective quality often dissatisfies consumers. This paper presents a mixed scheme to improve subjective quality in low bitrate video. Our scheme is a combination of several original techniques: fast dynamic key-frame/variable frame-rate coding, ringing effect reduction, band effect reduction, and resolution/quantization tradeoff. The scheme can be applied on many popular video-coding standards, such as MPEG-1, MPEG-2, MPEG-4, and H.264. Additional computing costs involved by the scheme are acceptable. Experiments show significant improvement of subjective quality, and prove that the scheme is valuable.
