Latest Patents

One of John William Urda's notable inventions is related to image scaling employing horizontal partitioning. This invention describes an apparatus, circuit arrangement, program product, and method for scaling an image by partitioning a source image into multiple sections. Each partition maintains a width that does not exceed the line buffer used in scaling. This innovative approach allows the scaled image's width to surpass the limitations of conventional full-width line buffers, subsequently permitting line buffers that are considerably smaller and more cost-effective, thereby reducing overall power consumption and circuit real estate.

Another critical patent of Urda involves the protection of copyright data within a computer system. His invention encompasses an apparatus, method, and program product for digitally processing an encrypted data stream scrambled according to content scrambling system (CSS) technology. This processing ensures that clear data is not communicated within the system during transfers from the central processing unit (CPU) to memory or system buses. Following descrambling of the CSS encrypted data stream, the data is re-encrypted before any transfers, maintaining the integrity of copyrighted materials while facilitating software descrambling.
