Description

According to the discussion on TMVP hook as proposed in JCTVC-L0177, POC difference 0 can never occur in HEVC version 1 and not need to be specified in HEVC version 1. However there is already such a case of POC difference 0 in the current text of JCTVC-L0030-v3.

The following sentence in section 8.5.3.1.8 Derivation process for collocated motion vectors
– If DiffPicOrderCnt( pic, currPic ) is less than or equal to 0 for every picture pic in every reference picture list of the current slice, mvCol, refIdxCol, and listCol are set equal to mvLXCol[ xPCol ][ yPCol ], refIdxLXCol[ xPCol ][ yPCol ] and LX, respectively with X being the value of X this process is invoked for.

should be replaced with
– If DiffPicOrderCnt( pic, currPic ) is less than 0 for every picture pic in every reference picture list of the current slice, mvCol, refIdxCol, and listCol are set equal to mvLXCol[ xPCol ][ yPCol ], refIdxLXCol[ xPCol ][ yPCol ] and LX, respectively with X being the value of X this process is invoked for.
