摘要: This paper focuses on two typical constraints present in current video delivery platforms such as IPTV: accommodating the diversity of consumer end-devices and coping with various bandwidth deployed network access technologies. We propose use Scalable Video Coding (SVC) extension H.264/AVC to cope these constraints: three different techniques combine SD HD versions a sequence one SVC stream are presented we assess how quality scalability compares spatial producing streams that can be tailored constraints. The results show proposed for combining perform equally good that, under certain conditions, outperforms
