Optical or electrical attenuation is provided at the infrared (IR) receiver of a first device, such as a remote control, together with a commensurate increase in output of the IR transmitter of an appliance, such as a set top box, to improve the signal-to-noise ratio of IR communications with respect to any background infrared radiation, such as radiation from a plasma display screen.

System and method for improved infrared communication between consumer appliances

A system and method for facilitating infrared (IR) communications from a first device, such as a set top box, to a second device, such as a remote control, in the presence of an IR noise generating device, such as a plasma television, by using at least one of the first device and the second device to actively reduce a level of IR noise being generated by the IR noise generating device during an IR transmission from the first device to the second device.

System and method for reduction of infrared noise during communication between consumer appliances

Circuitry using infra-red (IR) diodes in remote control units. In one embodiment an IR LED is used both as a transmitter diode and also as a receiver diode responsive to light to thereby develop photocurrents and/or voltages for use by external circuitry. In a second embodiment an improved amplifier circuit is provided for an IR LED and IR photo detector diode which is mounted behind, and receives light through, the transmitter IR LED.

IR receiver using IR transmitting diode

A hand-held controller having a plurality of console command buttons that, in response to activation, cause the transmission of commands for the purpose of controlling the operation of a video game console. Parental control is provided by preventing the transmission of commands to the video game console in response to activation of a console command button as a function of a parental control parameter that is provided to the hand-held controller.
