Method and apparatus for modulating a video signal with data
First Claim
1. A method comprising:
- receiving on the mobile electronic device, at a frequency, a transmission of a first encoded audio signal, the first encoded audio signal having first encoded information on a subcarrier of the frequency, the first encoded information including match data and an AB flag with a first status, the AB flag representative of which of plural different promotional opportunities are to be displayed on the mobile electronic device;
processing the first encoded audio signal on the mobile electronic device to extract the first encoded information from the first encoded audio signal;
selecting pre-stored promotional data on the mobile electronic device using the match data of the first encoded information;
receiving a transmission of a second encoded audio signal at the frequency, the second encoded audio signal having second encoded information on the subcarrier of the frequency, the second encoded information including the AB flag with a different, second status;
processing the second encoded audio signal on the mobile electronic device to extract the second encoded information; and
responsive to detecting a change in the status of the AB flag to the second status, displaying a promotional opportunity on the mobile electronic device, the promotional opportunity displayed using the pre-stored promotional data on the mobile electronic device.
