Title: David Oakley - Innovator in Video Technology
Introduction
David Oakley, an accomplished inventor based in San Diego, CA, has made significant contributions to the field of video technology, boasting a portfolio of three patents. His innovative work primarily focuses on hardware-efficient processes for video scaling and format conversion.
Latest Patents
Among his latest patents, the "Video Line Rate Vertical Scaler" stands out. This invention facilitates the conversion of component (VGA) video to television using an integrated circuit that implements line rate vertical scaling without requiring external memory. The technology combines scaling and filtering into a single process, utilizing a polyphase filter - a low pass filter with a fixed cut-off frequency and programmable delay. By modifying the coefficients of the polyphase filter, the scaled video signal is time-shifted, efficiently managing incoming video refresh rates. Notably, this innovation allows for the output of eight lines for every nine horizontal video scan lines, streamlining vertical scaling and potentially using a field buffer memory or FIFO memory for optimal performance.
Another significant patent from Oakley is the "Adaptive Graphics Video Standards Format Converter User-Interface." This adaptive user-interface is designed for traditional video standards converters, allowing a microcontroller to interface with the converter after interrogating a function switch matrix. By adjusting the two-dimensional sampling aperture of the converter to match incoming video timing, this invention facilitates seamless video output changes.
