Abstract
A method of transmitting data comprises modulating data symbols for transmission onto a sonic carrier signal and transmitting the modulated data using an electroacoustic transducer. The modulated data is transmitted by transmitting a portion of the modulated data for a first duration; pausing transmission for a second duration; and repeating the transmitting and pausing with further portions of the modulated data.
Claims20
A method of receiving data, the method comprising:
- receiving sound comprising a block of data modulated on an intermittent carrier signal;
- sampling the received sound to generate a sampled data stream;
- and
- demodulating the sampled data stream by:
- demodulating a portion of the sampled data stream corresponding to a first duration in which the intermittent carrier signal is present, and
- disregarding a portion of the sampled data stream corresponding to a second duration in which the intermittent carrier signal is not present.
One or more tangible, non-transitory computer-readable media storing instructions that, when executed by one or more processors of a media playback system, cause the media playback system to perform operations comprising:
- receiving sound comprising a block of data modulated on an intermittent carrier signal;
- sampling the received sound to generate a sampled data stream;
- and
- demodulating the sampled data stream by:
- demodulating a portion of the sampled data stream corresponding to a first duration in which the intermittent carrier signal is present, and
- disregarding a portion of the sampled data stream corresponding to a second duration in which the intermittent carrier signal is not present.
A playback device comprising:
- an electroacoustic transducer configured to generate audio signals;
- a computer-readable medium storing program code;
- and
- a processing system;
- wherein the program code, when executed by the processing system, causes the playback device to:
- receive sound comprising a block of data modulated on an intermittent carrier signal,
- sample the received sound to generate a sampled data stream, and
- demodulate the sampled data stream by:
- demodulating a portion of the sampled data stream corresponding to a first duration in which the intermittent carrier signal is present, and
- disregarding a portion of the sampled data stream corresponding to a second duration in which the intermittent carrier signal is not present.
