Abstract
A simple display of items from a list, which changes in synchrony with the corresponding video display, and permits simple navigation under user control. The display includes three control objects positioned below a video frame window on a display screen. A middle displayed object is located in a focus position and corresponds to the video segment currently being played in the video window. When play of the segment is complete, the object located to the right of the focus position moves and displaces the middle displayed object, most recently displayed within the focus position, to indicate a forward progression within the viewed video sequence.
