Abstract

An apparatus and method for marking availability of a candidate coding block for merge estimation of a current coding block within a coding tree unit (CTU). The candidate block may be marked as unavailable if a splitting depth of the current coding block is equal to or larger than a predetermined threshold and a first location of the candidate block and a second location of the current block are included in a same merge estimation region (MER). Otherwise, the candidate block is marked as available. A candidate block may be marked as unavailable also, when a parent block “parentCurr” of the current block and a parent block “parentCand” of the candidate block, with both parent blocks obtained by splitting, are the same block and when the size of the parentCand is smaller than a threshold.
