Noch mal ein Bild der Signalform und die Daten:

The IR Carrier is 39.2kHz. Data is modulated using a space coded signal with 8 data bits (data clock is 1200Hz,
but actual data rate varies depending on the data).

-- Timing based on 1/1200 second clock (~.833ms)
-- Signal is normally high (idle, no IR).
-- Start: signal goes low for 8/1200 sec.
-- Data bits: for each of 8 data bits, space encoded signal depending on bit value
-- Sends the most significant data bit first
-- If the data bit is 0: signal goes high for 1/1200 sec, and low for 1/1200 sec.
-- If the data bit is 1: signal goes high for 4/1200 sec, and low for 1/1200 sec.
-- BTW: The first bit (msb) is always 1 (valid codes are from $80 to $FF)
-- When completed, signal goes high again.
