US Patent 11277624 Bandwidth control methods for inter prediction

Techniques for implementing video processing techniques are described. In one example implementation, a method of video processing includes determining, for a conversion between a block of a video and a bitstream representation of the video, whether a bi-prediction coding technique is applicable to the block based on a size of the block having a width W and a height H, W and H being positive integers. The method also includes performing the conversion based on the determining.
