RESIDUAL PREDICTION MODE IN SCALABLE VIDEO CODING

摘要

Methods, devices, and computer code products for encoding and decoding a video signal including conditional encoding and decoding of a residual prediction flag for an enhancement layer only of all base layers are discrete layers. If some base layers are not discrete, the residual prediction flag is always encoded and decoded. Encoding and decoding the residual prediction flag can include using contexts which depend on whether the reconstructed prediction residual of the discrete base layers is zero or not.
