You can use the PhidgetIR to control devices
with remote control input - such as your TV or DVD player, from your
computer by having the PhidgetIR transmit remote control codes. Your
application can learn the signals from arbitrary remote controls.
The learned code can be retransmitted and will function just as if
you were pushing the same button on the actual remote. You can also
control your computer or Phidgets by recognizing a signal from any
remote and using it as an event in your application to trigger some
action.
The PhidgetIR can send and receive data encoded in various fashions
as pulses of infrared light. The various encoding that the PhidgetIR
supports are grouped under the general term ¡¥Consumer IR¡¦ or CIR.
CIR is generally used to control consumer products such as TVs, DVD
players, etc. with a wireless remote control, but in general can be
used for any application that needs to transmit low speed data wirelessly.
CIR is a low speed protocol - commands generally contain no more then
32-bits of data with a bit rate of at the most 4000 bits/second, but
usually much less. There is no concession for anti-collision, so only
one code can be transmitting at any time. Transmission distance depends
on the power of the transmitter, but needs to be line of sight - though
generally this can include bouncing off walls/ceilings, etc.
CIR data is transmitted using a modulated bit stream. Data is encoded
in the length of the pulses / spaces between pulses, of IR light.
The pulses of IR light are themselves modulated at a much higher frequency
(usually ~38kHz) in order for the receiver to distinguish CIR data
from ambient room light.
