Abstract:
The document discloses a method for communicating information, such as audiovisual data and other information to a user. The method includes receiving a broadcast signal on a content receiver. The broadcast signal includes a video signal and a graphical signal, and the graphical signal includes a matrix barcode. After the content receiver receives the broadcast signal, the content receiver determines whether the matrix barcode should be displayed. The determination that the matrix barcode should be displayed may be based on the geographic location of the content receiver or user settings/preferences stored on the content receiver. If the matrix barcode should be displayed, the content receiver creates and outputs a modified signal. The modified signal includes the video signal with the matrix barcode overlaid on top of the video signal. If the matrix barcode should not be displayed, the content receiver outputs the broadcast signal.
