789	Chroma bit depth should be used in filtering process	bbross		"In Void TComLoopFilter::xEdgeFilterChroma, the luma bit depth ""g_uiBitIncrement+g_uiBitDepth""is used to calculate tc:

      Int iBitdepthScale = (1<<(g_uiBitIncrement+g_uiBitDepth-8));
      Int iIndexTC = Clip3(0, MAX_QP+DEFAULT_INTRA_TC_OFFSET, iQP + DEFAULT_INTRA_TC_OFFSET*(ucBs - 1) + (m_tcOffsetDiv2 << 1));
      Int iTc =  tctable_8x8[iIndexTC]*iBitdepthScale;

This should be the chroma bit depth but I cannot find a corresponding BitDepthC in HM. In SPS, only QpBdOffsetC is set."	defect	closed	minor	HM-8.2	HM	HM-8.0	fixed		fbossen ksuehring davidf jct-vc@…
