Description

Otherwise might be added in following branch:

8.5.2.12 Derivation process for collocated motion vectors
...
– Otherwise (sbFlag is equal to 1), the following applies:

– If PredFlagLXCol[ xColCb ][ yColCb ] is equal to 1, mvCol, refIdxCol, and listCol are set equal to mvLXCol[ xColCb ][ yColCb ], refIdxLXCol[ xColCb ][ yColCb ], and LX, respectively, availableFlagLXCol is set to 1.
– Otherwise (PredFlagLXCol[ xColCb ][ yColCb ] is equal to 0), the following applies:

– If DiffPicOrderCnt( aPic, currPic ) is less than or equal to 0 for every picture aPic in every reference picture list of the current slice and PredFlagLYCol[ xColCb ][ yColCb ] is equal to 1, mvCol, refIdxCol, and listCol are set to mvLYCol[ xColCb ][ yColCb ], refIdxLYCol[ xColCb ][ yColCb ] and LY, respectively, with Y being equal to !X where X being the value of X this process is invoked for. availableFlagLXCol is set to 1.
Otherwise, both the components of mvLXCol are set to 0 and availableFlagLXCol is set equal to 0.

...

In addition, DiffPicOrderCnt( aPic, currPic ) is less than or equal to 0 for every picture aPic in every reference picture list of the current slice might be replaced by NoBackwardPredFlag is equal to 1 to simplify the spec.
