It isn't easy to read such a graphical representation. However, the IR signal sent by the
PACE Digital Receiver DC 220 KKD is shown in
this thread.
It is the IR protocol referred to as CanalSat, which is Manchester encoded. Note that most bi-phase protocols don't employ a leadin, but do use a start pulse. In IRP format CanalSat is {55.5k,250,msb}<-1,1|1,-1>(T=0,(1:1,D:7,S:6,T:1,0:1,F:7,-89m,T=1)+)
We have 1 bit of start pulse, 7 bits of device, 6 bits of subdevice, 1 bit of toggle, 1 separator bit and 7 bits of function code. That makes 23 bits.
I read your recorded signal as D=23, S= 0, T = 1, F= 2. The signals in the linked thread are 23.0 function 22 and 9. Since your T bit is a 1, this is the repeating part of the signal. Only the first frame will have T = 0. CanalSat is usually 56KHz.
I used
IRScope to decode the Pronto Hex from the linked thread. You could use
IrMaster to generate Pronto Hex of candidate IR signals, and import them into IRScope to see a graphical representation and compare it to your captures. (You'd need to reverse the bit definition from <-1,1|1,-1> to <1,-1|-1,1> to get the same signal polarity as your recorded signal.)
