Abstract
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).
Claims15
A method of transmitting a command from a remote controller to an audio device exchanging at least one audio signal with an audio accessory via a medium, said remote controller exchanging at least one control signal in which said command is encoded with said audio device, said method comprising the following steps:
- generating said at least one control signal in a non-audio frequency band separate from an audio frequency band in which said at least one audio signal is located, and superposing said at least one control signal and said at least one audio signal on said medium.
A remote controller for an audio device exchanging at least one audio signal with an audio accessory via a medium, said remote controller exchanging at least one control signal in which said command is encoded with said audio device, wherein said at least one control signal is in a non-audio frequency band separate from an audio frequency band in which said at least one audio signal is located and superposed on said at least one audio signal on said medium and said remote controller comprises means for encoding said command in said at least one control signal.
An audio device adapted to be remote controlled by a remote controller and exchanging at least one audio signal with an audio accessory via a medium, said remote controller exchanging at least one control signal in which said command is encoded with said audio device, wherein said at least one control signal is in a non-audio frequency band separate from an audio frequency band in which said at least one audio signal is located and is superposed on said at least one audio signal on said medium and said audio device comprises means for decoding said command encoded in said at least one control signal.
