In I.7.3.8.5.2 Coding unit extension syntax, depth_dc_sign_flag is signaled when depth_dc_abs[x0+k][y0+j][i] is greater than 0 as follows:

dcNumSeg = DmmFlag[ x0 + k ][ y0 + j ] ? 2 : 1 if( depth_dc_flag[ x0 + k ][ y0 + j ] )

for( i = 0; i < dcNumSeg; i ++ ) {

depth_dc_abs[x0+k][y0+j][i] if(depth_dc_abs[x0+k][y0+j][i] >0)

depth_dc_sign_flag[x0+k][y0+j][i]

}

On the other hand,in HTM-12.0, it is signaled when the absolute value of DcOffset is greater than 0 as follows:

Void TDecSbac::xParseDimDeltaDC( Pel& rValDeltaDC, UInt uiNumSeg ) {

UInt absValDeltaDC = 0; xReadExGolombLevel( absValDeltaDC, m_cDdcDataSCModel.get(0, 0, 0) ); rValDeltaDC = (Pel)absValDeltaDC + ( uiNumSeg > 1 ? 0 : 1 ); ... if( rValDeltaDC != 0 ) {

UInt uiSign; m_pcTDecBinIf->decodeBinEP( uiSign );

} ...

}

Signaling condition for depth_dc_sign_flag in WD should be aligned with HTM-12.0 as follows:

for example

dcNumSeg = DmmFlag[ x0 + k ][ y0 + j ] ? 2 : 1 if( depth_dc_flag[ x0 + k ][ y0 + j ] )

for( i = 0; i < dcNumSeg; i ++ ) {

depth_dc_abs[x0+k][y0+j][i] if((depth_dc_abs[x0+k][y0+j][i] - dcNumseg + 2) >0) or if((depth_dc_abs[x0+k][y0+j][i] + (dcNumseg > 1 ? 0 : 1 ) >0)

depth_dc_sign_flag[x0+k][y0+j][i]

}

#define NH_3D_FIX_TICKET_101 ( 1 && NH_3D_VER141_DEC_COMP_FLAG ) should be replaced with #define NH_3D_FIX_TICKET_101 ( 1 && !NH_3D_VER141_DEC_COMP_FLAG )

• Inter-view bi-prediction mismatch with identicalMotion Mismatch case conditions: V2 are bi-predicted from V0 and V1. (V0->V2<-V1) No Weighted Bi prediction is used. Forward MV0 is equal to backward MV1. RefPOCL0 is equal to RefPOCL1
