Abstract:
1. An audio-video (AV) system comprising a display screen, a context sensitive controller coupled to the screen and adapted to translate controller specific user input commands to peripheral input device appropriate messages to drive the peripheral input devices, wherein the peripheral input devices comprise analog and digital devices, wherein the controller is adapted to communicate with the analog input devices via IR signals sent from the controller to the analog input devices and communicate with the digital input devices via signals sent from the controller over a bidirectional bus when such devices are coupled to a plurality of input and output ports coupled to the controller, wherein the analog input devices being incapable of communicating over the bidirectional bus, an IR signal receiver coupled to the controller and adapted to receive user input commands, an IR emitter coupled to the controller, and a gate coupled to the emitter, the controller and the IR signal receiver.
