Description

In 8.5.5.3:
– The derivation process for collocated motion vectors as specified in subclause 8.5.2.12 is invoked with currCb, colCb, ( xColCb, yColCb ), refIdxL0 set equal to 0 and sbFlag set equal to 1 as inputs and the output being assigned to the motion vector of the subblock mvL0SbCol[ xSbIdx ][ ySbIdx ] and availableFlagL0SbCol.

– The derivation process for collocated motion vectors as specified in subclause 8.5.2.12 is invoked with currCb, colCb, ( xColCb, yColCb ), refIdxL1 set equal to 0 and sbFlag set equal to 1 as inputs and the output being assigned to the motion vector of the subblock mvL1SbCol[ xSbIdx ][ ySbIdx ] and availableFlagL1SbCol.

– When availableFlagL0SbCol and availableFlagL1SbCol are both equal to 0, the following applies for X = 0..1:

mvLXSbCol[ xSbIdx ][ ySbIdx ] = ctrMvLX (717)
predFlagLXSbCol[ xSbIdx ][ ySbIdx ] = ctrPredFlagLX (718)

The assignments of value for predFlagLXSbCol are not mentioned in the text when availableFlagL0SbCol or availableFlagL1SbCol equals to 1.
