Abstract
A communications system includes a first device with a first display, and a first processor configured to generate at least one coded image according to a selectable encoding scheme from among different encoding schemes, and display the coded image on the first display. A first communications device is coupled to the first processor. A second device includes a second camera configured to capture the coded image on the first display, a second communications device, and a second processor coupled to the second camera and the second communications device. The second processor is configured to send a status message, via the second and first communications devices to the first processor, related to whether the captured coded image is decodable based upon a currently selected encoding scheme.
