These formulae should probably read something like: offsetX = ( ChromaArrayType != 1 && ChromaArrayType != 2 ) ? 0 : ( mvCLX[ 0 ] & 0x7 ? 2 : 0 ) (8-106) offsetY = ( ChromaArrayType != 1 ) ? 0 : ( mvCLX[ 1 ] & 0x7 ? 2 : 0 ) (8-107) to properly account for 4:2:0 and 4:2:2. Note: there does not seem to be an appropriate version for the SCC text." defect closed major SCC text fixed CPR, interpolation patrice.onno@… rajan_joshi jct-vc@…
