Abstract:

Several techniques for video encoding and video decoding are described. One example method includes performing a conversion between a video unit of a current picture of a video and a bitstream of the video according to a rule. The rule specifies that, for a given picture to be available as a reference picture whose motion information is used for the conversion, the given picture has a same coding tree unit size or a same coding tree block size as the current picture.
