#1179 closed defect (wontfix)

Inconsistent initialisation values for intra_bc_flag

Reported by: peterderivaz Owned by:
Priority: major Milestone: RExt D7
Component: RExt text Version: RExt D4 (N1005) v3
Keywords: Cc: davidf, joel, teruhiko, jct-vc@…


Table 9-33 Values of initValue for ctxIdx of intra_bc_flag has the following values:

185 185 201 197 197 185 197 197 185

In order to match the code in table INIT_INTRABC_PRED_FLAG of ContextTables.h I believe these values should be:

197 197 185 197 197 185 185 185 201

Note that the values appear in I/P/B order in the specification, but in B/P/I order in the code.

This ordering issue has caused problems before, for example, see

By the way, in table 9-34 the specification has a typo and lists "intra_mc_flag" instead of "intra_bc_flag".
