Vicky, you're right. AS USUAL.
After posting my thing, I downloaded the .ict files and saw precisely what you say. If you or Rob want to delete my post, is ok with me, just to keep this thread clean of mistakes. _________________ Liz

If I deleted all my posts that had mistakes, it would be about half of them.
This does seem to be an interesting protocol. I'm always amazed at how Rob makes sense of these things.
I hope that Alan can capture the rest of the signals so we can analyze it more thoroughly. _________________ Remember to provide feedback to let us know how the problem was solved and share your upgrades.

I don't know if you guys already looked at this, but if this device is a Nova PVR-3001, then this post:
http://www.hifi-remote.com/forums/viewtopic.php?p=76796#76796
looks like very similar "symptoms" to those you have here, especially this comment:
Quote: | Unfortunately, IR scope sometimes seems to understand the codes with some buttons (and show a nokia device with some extra codes..) but most times with the majority of the buttons it doesn't seem to work. |
Interestingly, another part of that post seems to imply that the poster's OEM remote might have been UEI.
If you read down a couple of posts he adds more info: http://www.hifi-remote.com/forums/viewtopic.php?p=76805#76805
in which he says:
Quote: | XMP1.4 multiplayer asynchronous uni-directional protocol @ 38kHz. |
Probably you've already seen/remembered that (Vicky and Rob were both involved in the thread )- but I thought I'd mention it just in case it helps...

Do you need some more learned signals from me ? if so what ? |

I thought we did, but Jim really nailed the thing with his post, so I have opened the old PVR file
Pvr learns from another thread

Hi Jim
My participation in that thread was merely to have the user do the leg work and get the informtion into a form that we could use easier than a PCF file. PCF files are a royal pain for me because I have to reinstall ProntoNG every single time I use it. Something else I do on my PC seems to corrupt the installation between uses .
So I bit the bullet reinstalled prontoedit, opened the PCF file, imported the data into irscope and spit out a timing summary and a exported the pronto to a text file, see link above.
Interestingly I have been following the xmp conversations where we decided we could name ours xmp1 and xmp2 because we'd never see any of those other xmp formats here. _________________ Remember to provide feedback to let us know how the problem was solved and share your upgrades.

I did try to read that discussion, but 99% of it went so far over my head you'd never even see the vapour trail...

You are not alone there. I just keep reading and reading and hope it sinks in and I'll come to a aha moment. I got a handle on nokia last month so the hex isn't all that odd anymore. _________________ Remember to provide feedback to let us know how the problem was solved and share your upgrades.

I downloaded your summary.
I can see that it has the same basic "shape" as the Harmony learns if I put, say, the 2 sets of timings for the "five" key side by side - but that's about it, for me, at my level.
I hope it helps someone to understand it.

I looked at it this morning and think that this is a base 8 signal.
We suspect the leadin timing pair wrong.
Instead of 400,300 I tried 240,0 and got an extra data pair, but that was just to get the numbers to look better when rounding.
I then rounded to 80 and came up with 8 distinct timing pairs. I tried 40, but that gave me 9 distinct timing pairs, so 8 seemed like a better choice.
0=+160,-240
1=+160,-320
2=+160,-400
3=+160,-480
4=+160,-560
5=+160,-640
6=+160,-720
7=+170,-800
I then got this nonsense. But there were different frame endings which might be more of a clue to what is going on here.

Doh! I used my lookup tool for the NOVA and it looks like this could be cable/1559 or cable/1560. That would be bad news for slingbox users, since the protocol is going to be way to large to fit into the sling because of size limits. The protocol alone will be 500 bytes and then there is the device upgrade too.
I'd load it up and take a look, but I managed to get my widget curled around my leg, and when I got up and walked away I jerked it with enough force to pull all of the wires out of the USB end. I've got the wires stripped and ready to solder, but I've moved 2x since the last time I soldered and can't seem to locate it. _________________ Remember to provide feedback to let us know how the problem was solved and share your upgrades.

Could somebody with a widget anod one of these remotes; urc-7555, urc-7780, urc-7781, urc-7940 or urc-7750 setup SAT/1560 and take a picture of the number 5 so we can confirm that this is that xmp1.4 signal? _________________ Remember to provide feedback to let us know how the problem was solved and share your upgrades.

Here are .ict files for key 5 from SAT/1559 and SAT/1560 devices. The two signals seem to be similar but not identical. Neither DecodeIR nor the new ExchangeIR analysis can make anything of them!

Thanks Graham, that helped a lot. This is the same signal structure that we saw from the other sources. This would be the xmp1.4 4 player signal. The protocol is absolutely huge and I see no way to get this down to a size that can be loaded into a sling box. _________________ Remember to provide feedback to let us know how the problem was solved and share your upgrades.

I haven't been following this thread, but since Vicky prodded me for a .ict file, I've had a look to see if I can make sense of it. I feel that Vicky is wrong on the base 8 issue. I think it is better not to round, but to look at the raw timings. There is no logical reason why the timings are multiples of a common figure, and indeed in the XMP protocol itself they don't seem to be, they seem to be multiples with an offset. The best sense I can make is that there are four values within each range of 100us, at x13, x40, x67 and x90 microseconds, where x is a digit from 2 to 7 or 8. I'm not sure what the lowest and highest gap sizes seem to be. These figures are very close to uniform intervals of 25 us, but with an offset. However, if I am right then this isn't base 8, or even base 16 (like the ordinary XMP). It would mean at least 20 different values, depending on what the range ends really are, and I can't believe a base 32 protocol . So although the figures look very much like this to me, I have difficulty believing my own conclusion.
I will watch further developments in this thread with interest!

I am very appreciative of all the effort by all the expert within the forum that have been working on a solution for a bin file for Nova pvr 3001. The box I am attempting to control is for the Greek pay-tv operator NOVA in front of the box the label is Nova pvr 3001 , underneath the box its labeled Panasat pvr 3001 if that helps. I have also tried http://betaremotes.slingbox.com/ with no success |
