119	picture referred to by collocated_ref_idx shall not be the current picture itself	hanhuang		"The collocated picture can be the current picture itself when coding the first frame (P slice) in the condition of CPR enabled. It causes getting motion information from current block in getColocatedMVP(...) . 
  
The encoder need to put some constrain in CompressGOP(...) as in SCM, shown in the following.

    if ( !pcSlice->isIntra() && pcSlice->getEnableTMVPFlag() )
    {
      TComPic *pColPic = pcSlice->getRefPic( RefPicList( pcSlice->isInterB() ? 1-pcSlice->getColFromL0Flag() : 0 ), pcSlice->getColRefIdx() );
      if ( pColPic->getPOC() == pcSlice->getPOC() )
      {
        pcSlice->setEnableTMVPFlag( false );
      }
    }
