Abstract: 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.

Abstract translation: 媒体显示系统通过识别媒体信号中的模式和响应于识别的模式来修改媒体信号来增强内容。 例如，在电视广播环境中，媒体信号可以是电视节目。 一时，电视机可以包括汽车公司的标志。 系统将识别标识并将其与本地存储的增强内容或通过使用附加输入进行关联。 基于用户偏好（例如，用户是否对该特定汽车公司感兴趣）和相关的增强内容，系统将以适当的方式修改广播信号。 例如，增强内容可以是商业视频剪辑或本地汽车经销商的电话号码。 在这种情况下，对广播信号的修改可以包括在视频信号上覆盖本地汽车经销商的号码或缓冲广播信号并播放商业视频剪辑以执行内容增强。
