Abstract
Medium Grain Scalable (MGS) coding is widely used as the quality scalable video coding (SVC) method. In this paper, we study bitstream extractor for MGS-based bitstream. In MGS, the coded data corresponding to a quantization step size can be fragmented into at most 15 sub-layers, which is called MGS slices. The contribution of each slice to the video quality is evaluated by our proposed algorithm, and based on the importance of MGS slices, the optimal extraction is proposed to get the best video quality. Compared to conventional method of SVC, the proposed method can both expand the range of supported bitrates and improve the quality.
