Title: The Innovative Contributions of Peng Yin
Introduction
Peng Yin is a prominent inventor based in Princeton, NJ (US), known for his significant contributions to video transcoding technology. With a total of 5 patents to his name, he has developed methods that enhance the efficiency and quality of video processing.
Latest Patents
Among his latest patents is a "Video transcoder with spatial resolution reduction and drift compensation." This invention provides a method and system that reduces the spatial resolution of a compressed bitstream of a sequence of frames of a video signal. The process involves decoding the frames and storing them in a first frame buffer while performing motion compensation with full resolution motion vectors. The decoded frames are then down-sampled to a reduced resolution and stored in a second frame buffer. The reduced resolution frames are partially encoded to produce a compressed bitstream of the video, utilizing reduced resolution motion vectors during the partial encoding process. Another notable patent is the "Video transcoder with drift compensation," which compensates for drift in macroblocks of a partially decoded input bitstream. This method involves measuring an estimate of drift and translating it into an intra refresh rate, allowing for the modification of DCT coefficients and motion vectors in accordance with the mapping for each changed macroblock.
Career Highlights
Peng Yin has worked with esteemed organizations such as Mitsubishi Electric Research Laboratories, Inc. and Matsushita Electric Industrial Co., Ltd. His experience in these companies has contributed to his expertise in video technology and innovation.
