''I.7.4.9.6 It is a requirement of bitstream conformance that, when dbbp_flag[ x0 ][ y0 ] is equal to 1, inter_pred_idc[ x0 ][ y0 ] shall not be equal to PRED_BI.'' However, the HTM has forced any inherited bi-prediction MV in DBBP to be forward prediction. I think, a bug-fix should be added on I.8.5.3.2.1, point 14 as following 14. When predFlagL0 is equal to 1 and predFlagL1 is equal to 1, and ( nOrigPbW + nOrigPbH ) is equal to 12 or '''dbbp_flag is equal to 1''', the following applies: refIdxL1 = −1 predFlagL1 = 0",mismatch,closed,minor,3D-HEVC text,3D-HEVC Draft Text 4,fixed,"Bi-prediction, DBBP",tech jct-3v@…
