Title: The Innovations of William J Butera
Introduction
William J Butera is a notable inventor based in Arlington, VA (US). He has made significant contributions to the field of television technology, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is for "Extended Definition Television Systems." This invention focuses on methods and systems for adding additional information to broadcast motion picture signals. The goal is to enable advanced receivers to decode this information, thereby providing improved picture quality. Standard receivers can still display an image with minimally visible impairments. Notably, chrominance information can be generated at a fraction of the frame rate, allowing alternate frames to encode additional data, such as high-definition luminance information in the chrominance signal.
Another significant patent by Butera is for "Multiscale Coding of Images." This invention involves image encoding apparatus and methods that recursively decompose the luminance values of sequential frames into spatio-temporal spectral components. This is achieved through quadrature mirror filter (QMF) processing of the luminance values. The filtered signals are subsampled, and each decomposed level of the spectral components is coded by vector quantization.
