The Sky Digibox Infra Red Commands can be interpreted as 56 bit
commands. The first 32 bits are identical for every code sent. The last 24
bits contain the part of the code that changes.
The waveform shows a typical Sky Digibox Infra Red Remote Control code. The code was
sampled by connecting a Sound Blaster mic input to the supply & output from an Infra Red
transceiver. The code shown has been inverted by the transceiver, the codes transmitted by
the Digibox Interface take this into account.
