Abstract
A method includes receiving a reference frame, determining, for a current block, a scaling constant, determining a scaled reference block using the reference frame and the scaling constant, determining a scaled prediction block using the scaled reference block, and reconstructing pixel data of the current block and using the rescaled prediction block. Related apparatus, systems, techniques and articles are also described.
