Abstract

Methods, systems, and instrumentalities are described to implement single loop decoding, A video decoding device (VDD) may receive a video bitstream, which may include one or more bitstreams (e.g., base layer bitstream, enhanced layer bitstream, etc.) The VDD may generate a hybrid inter-layer reference (H-ILR) picture. The H-ILR picture may be generated based on one or more inputs including, for example, a first layer motion information, a processed (e.g., upsampled) first layer residue signal, a second layer texture information, etc. The first layer motion information may be derived from a compressed first layer motion field or an uncompressed first layer motion field. An H-ILR block of the H-ILR picture may be reconstructed by deriving motion information of the H-ILR block from one or more neighboring H-ILR blocks in the H-ILR picture, for example, when the neighboring blocks are inter-coded.
