Abstract
A method and device for determining residual data for encoding at least part of an image of an enhancement layer of video data, the video data including the enhancement layer and a base layer, the enhancement layer being composed of processing blocks and the base layer being composed of elementary units each having associated residual data, the method comprising for a processing block of the enhancement layer determining, based on at least the number of elementary units of the base layer spatially corresponding, at least partially, to the processing block, whether or not to use residual data of one or more of said spatially corresponding elementary units of the base layer for prediction of the processing block.
