METHOD AND DEVICE FOR IMPROVED MULTI-LAYER DATA COMPRESSION

摘要

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