Description
8.3.6 derivation of NoBackwardPredFlag is as below:
- If DiffPicOrderCnt( aPic, currPic ) is less than or equal to 0 for each active picture aPic in RefPicList0 or RefPicList1 of the current slice, NoBackwardPredFlag is set equal to 1.
- Otherwise, NoBackwardPredFlag is set equal to 0.
or seems somewhat ambiguous here. It could be interpreted that if the DiffPicOrderCnt condition is valid for either L0 or L1 list then you should set NoBackwardPredFlag to 1. Using and seems to make the meaning more unambiguous.
