Description

Shall

if( log2TrafoSize <= Log2MaxTrafoSize &&

log2TrafoSize > Log2MinTrafoSize &&
trafoDepth < MaxTrafoDepth &&
!( IntraSplitFlag && ( trafoDepth = = 0 ) ) )

split_transform_flag[ x0 ][ y0 ][ trafoDepth ]

be

if( log2TrafoSize <= Log2MaxTrafoSize &&

log2TrafoSize > Log2MinTrafoSize &&
trafoDepth < MaxTrafoDepth &&
!( IntraSplitFlag && ( trafoDepth = = 0 ) ) &&
!interSplitFlag )

split_transform_flag[ x0 ][ y0 ][ trafoDepth ]

in 7.3.8.8?

  • Resolution set to invalid
  • Status changed from new to closed

The condition you suggest to add is basically saying that split_transform_flag is not parsed when interSplitFlag is equal to 1 but this case is already covered by:

trafoDepth < MaxTrafoDepth

where both trafoDepth and MaxTrafoDepth (=max_transform_hierarchy_depth_inter) have to be equal to 0 for interSplitFlag to be equal to 1 (see semantics of split_transform_flag). Therefore, the condition you suggest is redundant and so there is no change needed.
