For the derivation of availableFlagB0, refIdxLXB0, predFlagLXB0 and mvLXB0 the following applies:
–	…
–	The variables availableFlagB0, refIdxLXB0, predFlagLXB0 and mvLXB0 are derived as follows:
–	If one or more of the following conditions are true, availableFlagB0 is set equal to 0, both components of mvLXB0 are set equal to 0, refIdxLXB0 is set equal to −1 and predFlagLXB0 is set equal to 0, with X being 0 or 1, and bcwIdxB0 is set equal to 0:
–	availableB0 is equal to FALSE.
–	availableB1 is equal to TRUE and the luma locations ( xNbB1, yNbB1 ) and ( xNbB0, yNbB0 ) have the same motion vectors and the same reference indices.
