Latest Patents

Wang's latest patents include innovative methods for motion estimation and encoding in MPEG systems. One of his patents, titled "Hybrid hierarchical/full-search MPEG encoder motion estimation," describes an apparatus and method for determining inter-frame motion during the compression of digital video data. This invention incorporates a computationally efficient hierarchical block-matching motion estimation technique alongside a full-search block-matching approach. The method involves filtering and decimating a macroblock and its corresponding search area, allowing for a more efficient block-matching search. The operating parameters adapt based on the type of frame being processed, ensuring optimal performance during video compression.

Another significant patent is the "MPEG encoder that concurrently determines video data encoding format and coding conditions selection apparatus." This invention is designed for inclusion in an MPEG-II encoder chip and focuses on selecting encoding parameters for a macroblock of video data. The encoder decision block (EDB) stratifies digital video data into multiple blocks, evaluating functions such as variance or mean square error while avoiding redundant computations. This approach allows for the determination of various encoding conditions based on the evaluations of the block functions.
