Abstract
A method for distributing context-based data using an acoustic receiving device and a high frequency analog acoustic signal is disclosed. The acoustic receiving device a high frequency analog acoustic signal. A high frequency analog acoustic signal is of a frequency of at least 21,000 Hz and contains encoded data. The high frequency analog acoustic signal is converted to a digital acoustic signal and then analyzed to obtain the encoded data. The data is decoded to obtain information, and the information is then displayed on the acoustic receiving device.
