Abstract
A system includes a shutter which selectively allows access to an infrared detector, when accessed directly by a processor-based system, such as a set-top computer system. In this way, infrared commands may be blasted from a set-top computer system to an appliance, e.g., a television receiver, without interference from other remote control units. When the controlling device is not sending signals to the television receiver, the shutter may allow other remote control units to control the appliance. The shutter may be a voltage controlled liquid crystal shutter, whose transmissivity is a function of the applied voltage.
