METHOD AND DEVICE FOR VIDEO SIGNAL SCALABLE CODING AND DECODING Russian patent published in 2011 - IPC H04N7/26 

FIELD: information technology.

SUBSTANCE: encoder for video signal scalable coding has an image encoder for generating a bit stream of the base layer and a bit stream of an improved layer. The bit stream of the base layer and the bit stream of the improved layer are formed by breaking down the image into multiple image blocks, grouping the multiple image blocks into at least one group of sectors in the bit stream of the base layer and into at least two groups of sectors in the bit stream of the improved layer, coding all of the at least one group of sectors in the bit stream of the base layer and less than all of the least two groups of sectors in the improved layer so that, at least one group of sectors from at least two groups of sectors in the bit stream of the improved layer is intentionally not coded, coding the syntax structure element in the heading to indicate at least one group of sectors in the improved layer which is intentionally not coded.

EFFECT: high efficiency of video signal scalable coding.
