PID $019B: Konka protocol

All of the other Akai TV remotes that I've captured use either the NEC1 protocol or the Konka protocol, but I've just captured one Akai remote that uses an as yet unidentified protocol.
I've loaded the learns to the Diagnosis Area:

Here's how I've decoded the signals:
Code: Select all
freq = 37.7
lead in = +3050 -3020
leadout + +500 -3970 +500 -23000
0 = +500 -1500
1 = +500 -2500

Now for my question. Is there a way to do this 2-part leadout using the IR engine or do you have to send the final pair seperately?

I never had a 100% understanding of the IR engine, so maybe there is a way, but I don't think I ever knew a reasonable way to do that.

There is at least one feature of the IR engine that we haven't documented, and that's the one that lets you send an NEC1 style signal rather than an NEC2 style signal. You'd think that we would have documented that one by now, but we haven't.

Well, it's still not documentation, but take a look at the PB file for the
Apple iPod Dock that I recently posted. It uses the flags to make an NEC1-style repeat, and not just for the S3C8. I sure could have used that documentation!

I just stumbled across this old post about the "Konka" protocol and it appears that it never did get added to DecodeIR, so here's another one for you Graham if you're interested.
The official UEI executor for this is $019B.
I don' think it ever got added to RM either, but it is in KM.

This appears to be a version of what you have documented with bits 5 and 6 of the R29 block both set - Lead-in burst, One-on, Lead-out. In the HCS08 engine these timings are only default ones, they have their own memory addresses and are only initialised to be a lead-in burst and One-on. A protocol can modify that data and so should be able to send the double lead-out you have described.

The Konka protocol is supposed to be supported by DecodeIR, i.e. there is code for it, so if it doesn't decode it then it sounds as if there is a bug. I will look into it. I'm looking at unusual protocols for other reasons at present, and Konka is one of those.
