multilayer adaptation for mgs-based svc bitstream
Medium grained scalability (MGS) of scalable video coding is expected to be of high interest due to the advantage of packet-based scalability. In this paper, we study multilayer adaptation for MGS-based bitstream. Our adaptation method not only considers which packets to be dropped, but also modifies layer dependency of NAL units to maintain bitstream conformance. Compared to conventional method of SVC, the proposed method can both expand the range of supported bitrates and improve the quality.
