Title: Chi Ouyang: Innovator in Motion Compensation and Compression Technologies
Introduction
Chi Ouyang is a notable inventor based in Fremont, California, recognized for his contributions to motion compensation and compression technologies. With a total of two patents to his name, Ouyang has made significant advancements in the field of digital encoding and decoding processes.
Latest Patents
Ouyang's latest patents include a method and system for a macroblock tiling format for motion compensation. This innovative approach groups picture data samples into tiles, which consist of a combination of luminance and/or chrominance data samples corresponding to a specified number of macroblocks. The method enhances the MPEG decoding process by efficiently mapping picture data samples to memory locations within a single memory page of a buffer memory that temporarily stores decoded pictures.
Another significant patent is a conversion system that utilizes programmable tables for compressing transform. This system converts run-level pairs into variable length codes (VLCs) for compression purposes. Each run-level pair includes a run and level value derived from scanning blocks of DCT coefficients. The system employs a programmable memory to store a segment address table, which comprises a list of base addresses for valid run values. An adder is used to determine the VLC address, which is then compared with an end address to manage out-of-bounds values effectively.
