METHOD OF TRANSMITTING A COMMAND FROM A REMOTE CONTROLLER TO AN AUDIO DEVICE, AND CORRESPONDING REMOTE CONTROLLER AND AUDIO DEVICE

摘要

A remote controller transmits a command to an audio device. The audio device exchanges at least one audio signal with an audio accessory via a medium. The remote controller exchanges at least one control signal in which the command is encoded with the audio device. The control signal(s) are generated in a non-audio frequency band and superposed on the audio signal(s) on the medium. The remote controller encodes the command in the control signal(s) and the audio device decodes the command encoded in the control signal(s).
