An Improved Infrared Signal Communication System and Method Including
Transmission Means Having Automatic Gain Control is disclosed. Also
disclosed is system and method that adjusts signal transmission power in
response to incident signal power amplitude. The preferred system
includes a control signal loop within the signal receiving system, and
the system further includes a signal transmitting system that is
responsive to the control signal loop. The preferred system includes
manual, semi-automatic and automatic modes of operation. Still further,
the preferred method includes at least two Ir-enabled appliances
"stepping" each other "down" in transmit power in response to directives
issued by the other Ir-enabled appliance.
