Abstract
The disclosure addresses methods and apparatus for evaluating video presentations, particularly those displaying a succession of generally static images to identify the transition from a first image to a second image. The change of images facilitates the insertion of chapter markers which may be later used to index the content of the video and to facilitate navigation to selected content in the video. In one implementation, a difference measurement will be made between selected frames of the video presentation and evaluated with a statistical measure of the magnitude of the difference measurements, such as a Root Mean Square analysis. In preferred implementations, all processing will be done in the digital domain.
