TRANSFERRING DATA VIA AUDIO LINK

摘要

Transferring data via audio link is described. In an example a short sequence of data can be transferred between two devices by encoding the sequence of data as an audio sequence. For example, the audio sequence may be a sequence of tones which vary in dependence on the encoded data. The sequence of data may be encoded by a first device and transmitted using a loudspeaker associated with the first device. At least one mobile communications device can be used to capture the audio sequence, for example using a microphone, and to decode the sequence, retrieving the data encoded therein. In some examples the encoded data may comprise a shortened URL or other information which can be used to control one or more aspects of the capture device.

1. A method of transmitting a data item to a mobile communications device comprising:
receiving a data item for transmission at a processor from a first device; transmitting a data token which is associated with the data item to the first device; receiving the data token from a second device, the second device having received the data token from the first device via an audio encoding, at least a portion of the audio encoding being imperceivable to a human ear; and transmitting the data item to the second device.
