High level syntax improvement on inter-layer prediction for SHVC/MV-HEVC

摘要

Syntax changes for SHVC/MV-HEVC coding apparatus and methods are described which improve efficiency. In a first portion, syntax of header signaling position under P or B-slice conditions are described, and a new condition to signal inter-layer prediction layer. A second portion describes use of an inter-layer reference picture set as an alternative to the first portion, and provides an arranged syntax to more efficiently signal inter-layer reference information. In a third portion, an inter-layer sample only prediction and TMVP interaction is described which reduces signaling needs for collocated references syntax.
