Section 8.4.3.1.2 (in H1003_dK version)

Reported by: madhukar Owned by: bbross
Priority: minor Milestone:
Component: Text Version: D6 (H1003) dI/dJ/dK
Keywords: Cc: bbross, wjhan, jct-vc@…

Description

Smoothing defined in Section 8.4.3.1.2 is getting applied to Intra_FromLuma mode (which has its own separately defined smoothing before downsampling in Section 8.4.3.1.8). I believe HM6 and earlier versions of HM do not apply this smoothing for Intra_FromLuma mode.

Fix: Change bullet 2 in 8.4.3.1.2 to:

  1. If intraPredMode is equal to Intra_DC *or Intra_FromLuma*, intraFilterType[ nS ][ IntraPredMode ] is set equal to 0.

One more fix is needed. nS = 64 case needs to be removed from Table 8-4 since 8.4.3.1.2 is called with TU sizes.
