Abstract
A method and system for navigating content in a personal video recorder (“PVR”) is disclosed. The PVR detects events, or dark frames, during recording of television content, and records the locations of the events. The PVR can use the recorded locations of the events by applying commercial grouping rules, contained in a logic that is accessible by a processing unit, to divide the recorded television program into scenes. In applying such commercial grouping rules, a group of back-to-back television commercials comprises a single scene. Such division allows a user to skip over an entire scene (e.g. an entire block of commercials) with the press of a single navigation button.
