Latest Patents

David A Rumball holds a patent for a "Method and apparatus for converting digital YUV video signals to RGB." This invention processes a composite video signal and converts it to component video signals, which are then digitally processed to produce reprogrammable digital RGB graphics signals. The process begins with digitizing a composite video signal, followed by converting digitized YUV component video signals into digitized RGB signals. This is achieved through a RAM-based table lookup technique that is optimized for the resolution of each component signal, minimizing memory requirements and computation overhead. In a specific embodiment, a Y or luminance signal with a resolution of 6 bits is utilized alongside a V component signal of 5 bits and a U component signal of 3 bits, all without noticeable degradation of RGB color quality.
