PROCESSING BITSTREAM CONSTRAINTS RELATING TO INTER-LAYER PREDICTION TYPES IN MULTI-LAYER VIDEO CODING

摘要

An apparatus for coding video information may include computing hardware configured to: when a current picture is to be predicted using at least inter layer motion prediction (ILMP): process a collocated reference index value associated with the current picture, wherein the collocated reference index value indicates a first reference picture that is used in predicting the current picture using inter layer prediction (ILP); and determine whether the first reference picture indicated by the collocated reference index value is enabled for ILMP; when the current picture is to be predicted using at least inter layer sample prediction (ILSP): process a reference index value associated with a block in the current picture, wherein the reference index value indicates a second reference picture that is used in predicting the block in the current picture using ILP; and determine whether the second reference picture indicated by the reference index value is enabled for ILSP.
