Abstract
A method and device for keyframe-based video displaying using a video cursor frame in a multikeyframe screen.Keyframe-based displaying of a video presentation enables a user to select among keyframes, and based on the selecting displays a substantially continuous video stream relating to the presentation. In particular, various keyframes are displayed in parallel in a reduced and static video format, and the displaying is controlled as starting from a particular active key frame which subsequently acts as a dynamic cursor frame within the video format. The cursor may be dynamic video plus dynamic audio, dynamic video alone, or static video per interval plus dynamic audio.
