Title:
METHOD AND APPARATUS FOR HIERARCHICAL PICTURE ENCODING AND DECODING
Document Type and Number:
WIPO Patent Application WO/2012/036468
Kind Code:
A2
Abstract:
A residual picture is decoded first by demultiplexing an input enhancement layer bitstream into one or more bitstreams corresponding to an order of quality layers. Next, a residual picture is restored by independently decoding the bitstream for each quality layer. The restored residual picture is stored in a frame buffer. A finally restored residual picture is output by adding, to the restored residual picture, a picture that has undergone motion compensation in a reference frame within a same enhancement layer.
