Abstract
A visualization system captures and analyzes a video signal to extract features in the video signal to render a graphical multi-dimensional visual representation of the program. The visualization system includes a memory and a processor and is programmed to extract features, augment the feature extraction with supplemental information, and render a visual summary to be displayed on a display device. Using the visual summary, a user can more easily determine the nature of a particular video program.
Claims36
