Abstract:
1. A method for generating a directional audio by a remote-control device combined with an audio generating device, the method comprising: transmitting, by the remote-control device, a command to an audio/video device to generate the directional audio through the remote-control device; transmitting, by the remote-control device, data indicating an approximate location of the remote-control device relative to the audio/video device; receiving, by the remote-control device, an audio signal from the audio/video device, wherein the audio/video device transmits the audio signal to the remote-control device in response to the transmitted command; and processing the audio signal with an ultrasonic carrier to generate the directional audio that is audible at the approximate location of the remote-control device and inaudible at locations other than the approximate location of the remote-control device; and outputting the directional audio using the audio generating device coupled to the remote-control device.
