#668 closed defect (fixed)

HM8/WD mismatch for coeff_abs_level_greater1_flag context derivation

Reported by: pieterkapsenberg Owned by: bbross
Priority: minor Milestone: D8
Component: Text Version: D8 (J1003) d7
Keywords: Cc: bbross, wjhan, jct-vc@…


In the WD, the following appears:

– If this process is invoked for the first time for the current sub-block scan index i, the following applies.

  • ....
  • The variable lastGreater1Ctx is derived as follows.
    • If the current sub-block with scan index i is the first one to be processed in this subclause for the current transform block, the variable lastGreater1Ctx is set equal to 0.

However, in HM-8.0 TDecSbac::parseCoeffNxN, line 1227:

  UInt c1 = 1;

Looks like the init here is 1, instead of 0 like the text says.
