Abstract

A method and apparatus for processing information stored on a storage medium, such as a digital video disk, involves accessing information stored on the medium and determining whether information stored on the storage medium includes unrated program information. If so, a user is given the opportunity to override a control condition of the system that prevents playback of unrated program information. If override is selected, playback of the unrated program information is enabled and, upon completion of playback, the control condition of the system may be restored to prevent playbak of other unrated program information. Override may be conditioned upon the user first entering a password.

Description

technical field [0001] The present invention relates to a user interface for a digital video device, and more particularly to a user interface for a digital video device that can limit the playback of stored video and audio information by responding to programs associated with such information, such as parental control ratings, that contain the video and audio information . Background technique [0002] Video signal processing systems using storage media on which digitally compressed video and audio information is recorded can provide users with numerous options for controlling the playback of video titles stored on such media. Such systems are rapidly gaining in popularity. Such a system includes a video disc player adapted to process information stored in accordance with the Digital Video Disc (DVD) specification. Information on DVD-formatted discs is recorded as discrete data packets according to appropriate video and audio compression standards, where specific data pack...
