Embodiment Construction

[0042] Embodiments disclosed herein are generally directed to beacon iteration formats for transmitting data in acoustic signaling tones, and configurations of decoding devices for detecting acoustic signal tones transmitted thereby. The decoding device may be configured to subsequently provide (eg wirelessly) an indication that the acoustic signal was received to the content management system. After receiving an indication of the received sonic signal from the decoding device, the content management system may provide specific content to the decoding device based on the particular received sonic signal, as discussed in detail in the above-referenced prior patent application.

[0043] In a further embodiment, the first mobile device may interact directly with the second mobile device to exchange information using acoustic signals, as described in further detail below.

Abstract

A disclosed device 2010, 2300 is configured to generate and transmit a sonic signal 2012 that encodes a symbol sequence, representing a data message, for delivery as audio content. The device includesan audio transmitter and a processor circuit. The processor circuit is configured to encode the data message as a sequence of symbols 2034, with each symbol 1802 encoding a data value thai is associated with respective phase characteristics of a transmitted audio carrier. The processor is further configured to generate 2102 audio samples of a digitized version of the sequence of symbols using thephase characteristics of the audio carrier associated with the symbols, and to control 2108 the audio transmitter to generate and transmit the sonic signal, based on the audio samples. A further disclosed device 2014 is configured to receive 2202 the sonic signal and to decode 2210 a symbol sequence by identifying symbols corresponding to determined phases of the sonic signal.
