Title: Innovations of Robert L. Miller
Introduction
Robert L. Miller is an accomplished inventor based in Davis, CA (US). He has made significant contributions to the field of video technology, holding a total of 2 patents. His work focuses on enhancing video encoding and processing techniques, which have applications in various multimedia systems.
Latest Patents
Miller's latest patents include an "Adaptive Differential Pulse Code Modulation Video Encoder" and a "Video Key Glow and Border Generator." The adaptive DCPM video encoder operates directly on a digitized composite video signal to generate a bit-reduced serial digital output signal. It features a feedback loop in the form of a recursive filter that helps determine a predicted value for subtraction from the digitized composite video signal. This process produces a difference signal with the color subcarrier frequency nulled out. The quantization transfer function for the quantizer is non-linear, allowing for fine resolution near zero and coarse resolution away from zero.
The video key glow and border generator provides a method for placing a border video signal around a selected object in a video image. This process involves inserting a video image of the selected object into a video image of a selected border video signal using a key signal. The key signal is processed to transform the step transitions into non-step transitions, which are then used to create a composite video image.
