Abstract:
In general, this disclosure describes techniques for improved inter-view residual prediction (IVRP) in three-dimensional video coding. These techniques include determining IVRP availability based on coded block flags and coding modes of residual reference blocks, disallowing IVRP coding when a block is inter-view predicted, using picture order count (POC) values to determine whether IVRP is permitted, applying IVRP to prediction units (PUs) rather than coding units (CUs), inferring values of IVRP flags when a block is skip or merge mode coded, using an IVRP flag of a neighboring block to determine context for coding an IVRP flag of a current block, and avoiding resetting of samples of a residual reference block to zeros during generation.
