#389 closed defect (fixed)

Text / HM mismatch for slice_type

Reported by: fbossen Owned by:
Priority: minor Milestone: HM-7.0
Component: HM Version: HM-6.0
Keywords: Cc: fbossen, ksuehring, davidf, jct-vc@…

Description

Text defines:
slice_type = 0 for P slice
slice_type = 1 for B slice
slice_type = 2 for I slice

HM defines:
slice_type = 0 for I slice
slice_type = 1 for P slice
slice_type = 2 for B slice

The numbering scheme in the text is aligned with prior AVC specification. It is therefore suggested to modify the SW to align it with the text.

When this was defined in AVC we expected P to be the most frequently used slice type. I think in HEVC we would now assume B to be the most likely slice type, so maybe using a value of zero for B would help to save some bits in common cases?
