I am assuming (given the ^ 0xff) that the hardware sends inverted bytes.
And that the reason ibuf[5] does not need ^ 0xff is that it already is
the inverted command (i.e. ibuf[5] == ~ibuf[4]).
To put it differently:
ibuf[2] = ~addr = not_addr;
ibuf[3] = ~not_addr = addr;
ibuf[4] = ~cmd = not_cmd;
ibuf[5] = ~not_cmd = cmd;
And the scancode can then be understood as:
addr << 16 | not_addr << 8 | cmd
Except for when addr = 0x00 in which case the scancode is simply NEC16:
0x00 << 8 | cmd
