#68 fixed MV clipping bug in the sub-PU MPI default MV generation tech jicheng

In HTM11, there is a MV clipping operation in the sub-PU MPI default MV generation, which is obviously a bug and should be removed to align with the WD. (This kind of bug was previously solved by NTT_BUG_FIX_TK54, but here it is introduced again by MPI_SUBPU_DEFAULT_MV_H0077_H0099_H0111_H0133.)

In TComDataCU.cpp, line 4499, the following coded should be removed:

clipMv( cMv );
#23 fixed Disparity vector derivation of VSP mode in depth coding tech hongbin.liu

In section H.8.5.4, NBDV is used to derive an initial disparity vector for both texture and depth. However, in HTM-6.1,NBDV is not called for depth, instead, (0, 0) is always used as an initial disparity vector. As shown in the following codes, in function TComDataCU::getInterMergeCandidates, NBDV is called only when "bNoPdmMerge" is false, and "bNoPdmMerge" is fasle for texture but is true for depth.



#if FCO_DVP_REFINE_C0132_C0170

if( !getPic()->getDepthCoded() )


getDisMvpCandNBDV(uiPUIdx, uiAbsPartIdx, &cDisInfo , true

#if MERL_VSP_C0152

, true

#endif );


A suggested revision is to change if(!bNoPdmMerge) to if(!bNoPdmMerge | | ( getSlice()->getIsDepth() && getSlice()->getViewId() ) )

#24 fixed cabac ctx initialization error for edge_Intra and SDC tech hongbin.liu

In HTM-6.1 ContextTables.h, Following array including INIT_EDGE_INTRA, INIT_EDGE_INTRA_DELTA_DC, INIT_SDC_FLAG, INIT_SDC_RESIDUAL_FLAG, INIT_SDC_SIGN_FLAG, INIT_SDC_RESIDUAL and INIT_SDC_PRED_MODE should be defined as "static const UChar" instead of "static const Short"
