Abstract
A single control allows selection and display of different video sequences from a DVD. No screen graphics are necessary to assist the user with operation, such as to show which buttons correspond to which sequences. A dedicated control, such as a button on a DVD player or television remote control device, is used to switch between two possible video tracks, or to otherwise select among multiple video tracks. Full-screen video tracks can be displayed without the need for visual indicators, such as thumbnail images, to identify selectable video tracks associated with different controls. Another aspect of the invention allows for modification of control information, such as navigation information, within a playback device.
