Transmitting first data in a radio signal and second data in an acoustic signal which is encoded using information from the first data

摘要

A method of wirelessly communicating between a first and second device is disclosed as well as devices for carrying out the method. The method has the steps of transmitting a first set of data from the first device to the second device using a radio signal and transmitting a second set of encoded data from the first device to the second device using an acoustic signal. The first set of data comprises information related to the encoding of the second set of data.
