IR Remote Signals

Here is a picture I downloaded showing the waveform from pressing a few buttons (in this example pressing the buttons 1, 2,4 and 7) on a remote control. Arduino will have to decode each of these codes. In addition, the code depends on the manufacturer of the remote.

Seems too complex for my taste. You need to read every pulse and then figure out that the sequence of pulses corresponds to. The following links gives a flavor of what is involved:
