US Patent Issued to Avid Technology on Dec. 23 for "Fixed rate intraframe compression and decompression of video based on visual quality" (German Inventor)

ALEXANDRIA, Va., Dec. 23 -- United States Patent no. 12,506,887, issued on Dec. 23, was assigned to Avid Technology Inc. (Burlington, Mass.).

"Fixed rate intraframe compression and decompression of video based on visual quality" was invented by Markus Weber (Woerth, Germany).

According to the abstract* released by the U.S. Patent & Trademark Office: "DCT-based methods for fixed bit rate, intraframe compression of video are based on the visual quality of the resulting decompressed imagery. In general, this involves assigning an initial bit budget per macroblock of a given video frame, resulting in degrees of compression, i.e., quantization scale factors, that vary among the macroblocks according to their complexity. The scale factors are t...
