Latest Patents

Among his latest patents, one significant invention is focused on "Browsing JPEG images using MPEG hardware chips." This patent addresses the rapid throughput of still image compressed data, allowing for the presentation of images in quick succession. By utilizing a hardware decoder designed for moving images, Neil's invention reduces the processing load typically required by software. The still image data undergoes partial decoding in software, which is then re-encoded and reformatted for compatibility with the hardware decoder. This innovative approach results in a throughput increase of four-fold or more, significantly enhancing the efficiency of image browsing.

Another notable patent is "Fast JPEG Huffman encoding and decoding." This invention simplifies the Huffman encoding process, particularly from a packed data format, by employing two different table formats based on code length. The size of the Huffman tables is reduced, and decoding time is minimized by testing for the length of valid Huffman codes in a compressed data stream. This method allows for a direct index into Huffman table symbol values, greatly reducing the size of the look-up tables used.
