Upon receipt of the code, indicating the received inaudible signal 210 from the portable multifunction device 202, the content management system 200 may provide particular content or a pointer to that content to the portable multifunction device 202, the content being selected based on the particular inaudible signal received. Additional threshold triggers 502 may be delivered to require additional actions to unlock the content.
H04M 1/215 - Combinations with auxiliary equipment, e.g. with clocks or memoranda pads by non-intrusive coupling means, e.g. acoustic couplers
H04M 1/50 - Devices which can set up and transmit only one digit at a time by generating or selecting currents of predetermined frequencies or combinations of frequencies
H04N 21/414 - Specialised client platforms, e.g. receiver in car or embedded in a mobile appliance
H04N 21/422 - Input-only peripherals, e.g. global positioning system [GPS]
H04N 21/658 - Transmission by the client directed to the server
H04N 21/8358 - Generation of protective data, e.g. certificates involving watermark
H04B 11/00 - Transmission systems employing ultrasonic, sonic or infrasonic waves
H04L 29/08 - Transmission control procedure, e.g. data link level control procedure
H04M 1/72457 - User interfaces specially adapted for cordless or mobile telephones with means for adapting the functionality of the device according to specific conditions according to geographic location
