First Claim
1. A method comprising:
- searching by a server, in response to receiving a search term from a user via a user interface of a mobile control device, a plurality of multimedia data stored in a database at a multimedia server to generate matched multimedia data associated with the search term, the matched multimedia data comprising video content and one or more of a condensed representation pertaining to the video content, offline transcriptions, and closed captions associated with the video content, wherein the condensed representation, the offline transcriptions, and the closed captions associated with the video content are stored in the database, wherein the matched multimedia data is generated by;
analyzing, by a media metadata extraction device, the video content and identifying video shot boundaries in the video content;
extracting, by the media metadata extraction device, from the video content, (1) text from the closed captions and (2) a frame corresponding to the text; and
extracting, by the media metadata extraction device, small segments of organized multimedia data based on topic boundaries and the video shot boundaries, each small segment of the small segments being smaller than a respective program containing the small segments, to yield the matched multimedia data;
displaying, with the matched multimedia data and via the user interface, a plurality of command icons for controlling which display device of a plurality of external devices to display a selected video content;
receiving, via the user interface of the mobile control device and from the user, a choice from the matched multimedia data to yield the selected video content; and
receiving, via the user interface of the mobile control device, a user input to display the selected video content on one of a first display device and a second display device of the plurality of external devices, wherein the plurality of command icons remains on the user interface of the mobile control device after one of the first display device and the second display device has been selected for control so that the user can assert control commands regardless of wherein the user is in a navigation session.

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.
