JP1 Remotes

I learned some functions from the Samsung BD-P1000 BluRay player remote and loaded them into IR. Usually DecodeIR recognizes the protocol and gives a nice decode to create a device ugprade. In this case it recognized a bunch of Gap-497-abcd-ef protocols which appears to me it couldn't recognize the protocol and pieced together fragments as best it could.

The functions were learned on a RS 15-2117 remote. I'm using IR 6.20 with DecodeIR 2.31

I was wondering if anyone could help diagnose what is going on.

I uploaded the IR file here:

I expect one of the experts can determine SOMETHING from your IR file, but I'll ask you the standard learning questions:
(0) Do the learned signals work?
(1) New batteries in the sending remote?
(2) New batteries in the 2117?
(3) proper learning technique? (steady remotes - on a table facing each other about 2 inches apart? 2117 is learning before the OEM remote button is pressed? OEM button HELD until 2117 indicates "success"?)

Of course, I imagine there have not yet been too many HD DVD players decoded, so this may be a brand new protocol that has not previously been seen/decoded, in which case an expert will have to do this for you.

Last thing - do you have ANOTHER JP1 learning remote? I have a 1994, 2117, 8910, and HTPro, and my experience has been that for WHATEVER reason I don't know, the 2117 is the worst learner of the bunch. Exactly the same OEM signals learn and decode fine on the 1994 and 8910, while the 2117 requires several attempts and sometimes doesn't want to learn at all.

Rob, have you seen this one before? Do you know if UEI already has an executor for it?

It is 36 bits with an extra burst after the first 16 bits. Other than that extra burst and the extra four bits it has roughly the same timing as NECx2.

I think the last 8 bits are the check byte for the previous 8 bits. I don't know if anything in the first 20 bits is a check part.

If you read IRP notation, I think it is

{38.4k,490}<1,-1|1,-3>(9,-9,D:8,S:8,1,-9,X:4,F:8,~F8,1,-116)+

With D=32, S=0, X=7

Well, although most Samsung DVD upgrades in the file section use Aiwa/102, THIS ONE uses a manual protocol that might work for you. The comments say:

Thanks for looking. I think it will end up being easier to create a device upgrade after DecodeIR can recognize the protocol.

I tried the upgrade you pointed to unmodified and it had no effect. Probably need to tweak the protocol or change the device/subdevice #s.

BTW I remember in the past IR would print the frequencies on the learned signals page so I could kind of work out the bits. How do I enable that display? Does it only do it for frequencies it doesn't recognize? Is there a better way to display the frequencies (from the IR file) other than working it out by hand?

Here's the breakdown of the signals as I see them (which is in agreement with John's finding):

freq = 38.2
li= +4466 -4436
lo= +496 -57034
2 = +496 -4446 (OneOn, LeadinOff)
1 = +496 -1454
0 = +496 -486

00000100 00000000 2 1110 00011000 11100111 - up
00000100 00000000 2 1110 10011000 01100111 - down

Sliv, from the European OFA CS, sent me an IR file for this device, which I have converted into a KM upgrade...

Btw, the word I hear from UEI is that this new protocol is likely proprietry to Samsung, which might be worth keeping in mind when it comes to naming it for DecodeIR.

Thanks for putting that together. I ended up returning the BD-P1000 because the early source material just didn't have that great PQ so I won't be able to test the upgrade out. I'm sure someone else will apreciate it though.
