Abstract:
1. An apparatus, comprising: a remote for controlling one or more devices in connection with a base station located in an environment including an approximate line-of-sight transmission space, the remote operable to continuously receive an infrared frequency beacon signal, transmitted by the base station using a transmitter, wherein the infrared frequency beacon signal includes a sequence of pulses representing at least one channel information portion, wherein the at least one channel information portion includes information indicating a radio frequency, the infrared frequency beacon signal transmitted within and contained substantially within the approximate line-of-sight transmission space between said transmitter of the base station and the remote, the remote operable to establish bi-directional communications with the base station for controlling one or more devices and configured to transmit an audio signal representative of sounds received at a microphone coupled to the remote using the radio frequency designated by the at least one channel information portion, wherein the remote is configured to detect that it has left said approximate line-of-sight transmission space by detecting termination of reception of said infrared frequency beacon signal, and the remote is further configured to terminate the bi-directional communications using said radio frequency when the remote detects the termination of reception of said infrared frequency beacon signal.
