A scalable video coding(SVC) structure with low encoding complexity is designed based on the distributed video coding(DVC) technology.The structure is spatially scalable.Only conventional intra coding technology and DVC technology are used in all coding layers so as to keep the encoding complexity in a much lower level.A double search and residual compensation based(DSRCB) side information(SI) generating algorithm and a temporal-spatial based(TSB) virtual noise model are proposed for the enhance...
