Abstract
An encoder and method for encoding data in a scalable data compression format are described. In particular, process for encoding spatially scalable video are described in which the base layer uses downscaled residuals from a full-resolution encoding of the video in its motion estimation process. The downscaled residuals may also be used in the coding mode selection process at the base layer.
