Selection graphics overlay of matrix code

摘要

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.

1. A method for communicating information to a user, comprising the operations of:
receiving on a content receiver a broadcast signal comprising a video signal and a graphical signal, wherein the graphical signal comprises a matrix barcode and data instructions configured to instruct a processor of the content receiver of criteria for when to display the matrix barcode; determining at the content receiver that the criteria received for when to display the matrix barcode have been satisfied; creating a modified signal at the content receiver, wherein the modified signal comprises the video signal with the matrix barcode overlaid on the video signal; and providing a user specific content; and updating the matrix barcode to include the user specific content prior to outputting the modified signal; outputting the modified signal; and wherein a display location of the matrix barcode on a display device is determined by the user specific content.
