Abstract: A sorting approach for Scalable Video Coding (SVC) streaming is proposed for video transmission. By the accurate states selection and the effective approximate distortion calculation of the fully scalable video streaming, the proposed approach can priority transmit the scalable streaming owning better rate-distortion performance, which improves effectively the reconstructed quality of video streaming. A state model is built to select layered streaming from the fully scalable video streaming, and the distortion approximate formula of the scalable streaming is deduced. The scalable streaming is reordered by employing the rate-distortion optimization under certain bandwidth limitations. The simulation results show that the proposed approach can improve the reconstructed quality of video streaming.
