Phidgets 1055_0B PhidgetIR Remote Control
You can use the PhidgetIR to control devices with remote control input - such as your TV or Blu-ray player - from your computer by having the PhidgetIR transmit remote control codes. Your application can learn the signals from any remote controls. The learned code can be retransmitted and works as if you were pressing the same button on the actual remote. You can also control your computer or Phidgets by detecting a signal from any remote and using it as an event in your application to trigger an action.
The PhidgetIR can send and receive data encoded in various ways as infrared light pulses. The various encodings that the PhidgetIR supports are grouped under the general term "Consumer IR" or CIR. CIR is generally used to control consumer products such as televisions, Blu-ray players, or speaker systems with a wireless remote control, but can generally be used for any application that needs to transmit data wirelessly at low speed.
CIR is a low-speed protocol - commands typically contain no more than 32 bits of data at a bit rate of 4000 bits/second or less, but usually much less. There is no collision protection, so only one code can be transmitted at a time. The transmission distance depends on the power of the transmitter, but must be within line of sight, which can generally include bouncing off walls and ceilings.
CIR data is transmitted using a modulated bit stream. The data is encoded in the length of the IR light pulses or the spacing between pulses. The IR light pulses themselves are modulated at a much higher frequency (typically ~38 kHz) to allow the receiver to distinguish the CIR data from ambient light in the room.
