US Patent Issued to Apple on Aug. 19 for "Systems and methods of rate control for multiple pass video encoding" (California Inventors)

ALEXANDRIA, Va., Aug. 20 -- United States Patent no. 12,395,642, issued on Aug. 19, was assigned to Apple Inc. (Cupertino, Calif.).

"Systems and methods of rate control for multiple pass video encoding" was invented by Sorin C Cismas (Saratoga, Calif.) and Ganesh G Yadav (Fremont, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "This disclosure is directed to systems and methods of rate control in multiple pass video encoding. The video encoder may complete multiple encoding passes for slices of an image. Rate control algorithms may be implemented that scale the quantization step size and quantization matrix values depending on the determined size of the image slices. This may enable the size of slices ...
