Abstract

A system and method are provided for content-based non-linear control of video data playback. A multimedia database having multimedia data including multimedia content data is searched based on a user query to determine a first set of multimedia data. The multimedia data includes indexes to and condensed representations of corresponding video data stored in a video database. A portion of the first set of multimedia data is displayed at a control device in response to the user query. A user of the control device selects an element of the first set of multimedia data for video playback and video data corresponding to the element delivered to a video device for playback. A user of the control device selects an element of the first set of multimedia data for additional information and a second set of multimedia data corresponding to the element delivered to the control device.
