Inconsistency between reference decoder and spec in filtering process for chroma block edges

Description

In section 8.7.2.5.5 of P1005, it says:

The variable QpC is determined as specified in Table 8-10 based on the index qPi derived as follows:

qPi = ( ( QpQ + QpP + 1 ) >> 1 ) + cQpPicOffset (8-339)

In order to be internally consistent with section 8.6.1 and also with the reference decoder, I think this should instead say:

  • If ChromaArrayType is equal to 1, the variable QpC is determined as specified in Table 8-10 based on the index qPi derived as follows:

qPi = ( ( QpQ + QpP + 1 ) >> 1 ) + cQpPicOffset (8-339)

  • Otherwise, QpC is set equal to Min(qPi, 51).
