12 Every time a key is pressed on a remote controller, a scan code is produced.
13 Also, on most hardware, keeping a key pressed for more than a few dozens of
14 milliseconds produce a repeat key event. That's somewhat similar to what
22 produces one event for a key press and another one for key release. On
23 infrared-based remote controllers, there's no key release event. Instead,
24 an extra code is produced to indicate key repeats.
43 scan code, being 8 bits for address (usually it is a fixed number for a
44 given remote controller), followed by 8 bits of code. A bit "1" is modulated
48 At receiver, a simple low-pass filter can be used to convert the received
70 corresponding scan code. The protocols supported by the RC core are
