 4x4 luma transform block coded in sliceQ and associated with the 4x4 luma block containing sample qo contains non-zero transform coefficient levels). NOTE 4 - The array rSL contains samples for the accumulated residual signal. Transform coefficient values of layer representations that are used for inter-layer prediction are taken into account. Otherwise, if profile_idc is equal to 83 and any of the following conditions are true, bS is set equal to 2: cTrafo[ mbAddrP ] is equal to T_8x8 and the array sTCoeff[ mbAddrP ] contains non-zero scaled transform coefficient values for the 8x8 luma transform block associated with the 8x8 luma block containing sample Po, cTrafo[ mbAddrP ] is equal to T_4x4 and the array sTCoeff[ mbAddrP ] contains non-zero scaled transform coefficient values for the 4x4 luma transform block associated with the 4x4 luma block containing sample Po, cTrafo[ mbAddrQ ] is equal to T_8x8 and the array sTCoeff[ mbAddrQ ] contains non-zero scaled transform coefficient values for the 8x8 luma transform block associated with the 8x8 luma block containing sample qo, cTrafo[ mbAddrQ ] is equal to T_4x4 and the array sTCoeff[ mbAddrQ ] contains non-zero scaled transform coefficient values for the 4x4 luma transform block associated with the 4x4 luma block containing sample qo. Otherwise, if mixedModeEdgeFlag is equal to 1 or any of the following conditions are true, bS is set equal to 1: 1. numMvP is not equal to numMvQ. numMvP and numMvQ are both equal to 1 and any of the following conditions are true: refP and refQ specify different reference pictures, the absolute difference between the horizontal or vertical components of the motion vectors mvP and mvQ is greater than or equal to 4 in units of quarter luma frame samples. numRefP and numRefQ are both equal to 2 and any of the following conditions are true: Rec. ITU-T H.264 (01/2012) refLOP and refL 1P specify different reference pictures and any of the following conditions are true: both of the following conditions are true: refLOP and refL0Q specify
