Abstract
A plurality of audio signals are broadcasted concurrently on a plurality of substantially separate audio channels. Each of the audio channels has a center frequency greater than approximately 16 kHz. Broadcasting the audio signals causes one or more clients to automatically retrieve a resource from a resource location. The plurality of audio signals collectively encode a resource identifier that describes the resource location.
Claims21
A method comprising:
- broadcasting a plurality of audio signals concurrently on a plurality of substantially separate audio channels, each of the audio channels having a center frequency being greater than approximately 16 kHz, thereby causing one or more clients to automatically retrieve a resource from a resource location, wherein the plurality of audio signals collectively encode a resource identifier that describes the resource location.
A method comprising:
- receiving a resource identifier;
- segmenting the identifier into a plurality of parts;
- encoding each one of the plurality of parts, thereby producing a plurality of encoded signals;
- modulating each one of the plurality of encoded signals onto a plurality of audio channels, each one of the plurality audio channels having a center frequency greater than about 16 kHz and each one of the plurality of audio channels having a center frequency substantially different from each other one of the plurality of audio channels;
- and
- broadcasting the plurality of encoded signals concurrently on the plurality of audio channels.
