ALEXANDRIA, Va., March 24 -- United States Patent no. 12,587,653, issued on March 24, was assigned to Google LLC (Mountain View, Calif.).
"Spatial layer rate allocation" was invented by Michael Horowitz (Austin, Texas) and Rasmus Brandt (Mountain View, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A method includes receiving transform coefficients corresponding to a scaled video input signal, the scaled video input signal including a plurality of spatial layers that include a base layer.
