Abstract:
A video decoder can be configured to determine that a block of video data is encoded using a bi-directional inter prediction mode; determine that the block of video data is encoded using a bi-directional optical flow (BIO) process; inter predict the block of video data according to the bi-directional inter prediction mode; perform the BIO process for the block, wherein performing the BIO process for the block comprises determining a single motion vector refinement for a group of pixels in the block, wherein the group of pixels comprises at least two pixels; refine the group of pixels based on the single motion vector refinement; and output a BIO refined predictive block of video data comprising the refined group of pixels.

Claim (Index 15):
The device of  claim 12 , wherein:\n to inter predict the block of video data, the one or more processors are configured to locate a first reference block in a first picture, locate a second reference block in a second reference picture, and generate a first predictive block based on the first reference block and the second reference block, wherein the group of pixels belongs to the first predictive block; and to perform the BIO process for the block, the one or more processors are configured to apply the BIO process to the group of pixels of the first predictive block to generate the BIO refined predictive block.
