He has made significant contributions to the field of video encoding technology, holding two patents that showcase his expertise and innovative spirit. His work primarily focuses on enhancing the efficiency and effectiveness of video encoders.

Latest Patents

Adrian's latest patents include a "Fractional motion estimation engine with parallel code unit pipelines." This invention describes a video encoder that features an integer level motion estimation hardware component. This component is designed to determine candidate integer level motion vectors for the video being encoded. Additionally, the encoder includes a fractional motion estimation hardware component that refines these candidate integer level motion vectors into candidate sub-pixel level motion vectors. The design incorporates parallel pipelines that process coding units of a video frame simultaneously, enhancing the encoding process.

Another significant patent is titled "Supporting multiple partition sizes using a unified pixel input data interface for fetching reference pixels in video encoders." This invention involves a controller that manages the transfer of a reference pixel block of a video during encoding. The controller determines if any part of the reference pixel block extends outside the video frame. If so, it fetches the portion of the reference pixel block that is within the frame from memory storage, pads the missing portion with pixel data, and transfers the complete reference pixel block as needed.
