Document Type and Number:
WIPO Patent Application WO/2021/008513
Kind Code:
A1
Abstract:
A method of visual media processing, comprising:performing a conversion between a current video unit of a visual media data and a bitstream representation of the visual media data, wherein the bitstream representation is configured in accordance with a format rule that specifies that a maximum transform block size is equal to or less than a maximum coding tree unit (CTU) size used for the conversion.
