A media display system enhances content by recognizing patterns in the media signal and modifying the media signal responsively to the recognized patterns. For example, in a television broadcast environment, the media signal could be a television program. At one instant, the television could include a logo of a car company. The system would recognize the logo and correlate it with enhanced content stored locally or by using additional input. Based on user preferences (e.g., whether the user is interested in that particular car company) and the correlated enhanced content, the system would modify the broadcast signal in appropriate way. For example, the enhanced content could be a commercial video clip or the phone number of a local car dealer. The modification to the broadcast signal could, in such a case, include overlaying the local car dealer's number on the video signal or buffering the broadcast signal and playing the commercial video clip to perform content enhancement.
