Title: The Innovations of Stuart E. Lang
Introduction
Stuart E. Lang is a notable inventor based in Montville, NJ (US), recognized for his contributions to video decoding technology. With a total of 5 patents, Lang has made significant advancements in the field of digital video processing.
Latest Patents
Lang's latest patents include a method of encoded video decoding, which involves a sophisticated three-stage process. The first stage applies a multi-dimensional digital chrominance bandpass filter to the digitized encoded video signal, producing a chrominance signal. This signal is then subtracted from the digitized encoded video signal to create a luminance signal. The second stage detects edges and peaks in the chrominance signal, correcting the luminance signal where necessary to produce a chrominance corrected luminance signal without dot crawl errors. An intermediate corrected chrominance signal may also be derived from this stage. The third stage filters the chrominance signal to reduce peaks and enhance edges, resulting in a corrected chrominance signal with minimized cross color errors. Another significant patent involves digital prefiltering of encoded video signals, which aims to prevent cross color and dot crawl errors during the decoding process. This method filters both luminance and chrominance components to generate correction values that enhance the quality of the encoded video signal.
