Description

In
"8.5.3.1. Decoding process for luma residual blocks"
"8.5.3.2. Decoding process for chroma residual blocks"
"8.7.1.1. Derivation process of transform unit boundary"

Remove the first parentheses in:

"The variable log2TrafoWidth1 is set equal to (log2TrafoWidth − 2) * InterTUSplitDirection.
The variable log2TrafoHeight1 is set equal to (log2TrafoHeight − 2) * (1 − InterTUSplitDirection)"

to fix the calculation of log2TrafoWidth1 and log2TrafoHeight1

"The variable log2TrafoWidth1 is set equal to log2TrafoWidth − 2 * InterTUSplitDirection.
The variable log2TrafoHeight1 is set equal to log2TrafoHeight − 2 * (1 − InterTUSplitDirection)"

Furthermore, the following comment in dI:
"[Ed. (KS): Need to be updated on second depth for non square transform tree. In 16x16 CU, second TU depth should have four square transforms in a row or column. ]"
can be removed in:

  • 7.3.8 Transform tree syntax
  • 8.5.3.1 Decoding process for luma residual blocks
  • 8.5.3.2 Decoding process for chroma residual blocks
