Two issues: 1) In the original file from IrScrutinizer, there are two CR and one LF, and IRScope doesn't like that. 2) the leadouts are given as about 127mS, which causes IRScope to treat the file as one really long macro.

I edited the file to eliminate the extraneous CR, and to make the leadouts 500mS. http://www.hifi-remote.com/forums/dload.php?action=file&file_id=13795

I think issue 1) is a conflict between Windows and Linux conventions.

I also found that if I replaced the first line with one from a real ict file, IRScope would at least open the file, but the lines looked the same, so I don't know why that would make a difference. I need to open them in a hex editor to see if there's an invisible difference.

Btw, what ae CRs and LFs?

Carriage Return and LineFeed. Windows wants the end of a text line in a file to be terminated with CR and LF. Linux wants only a LF. Java has to operate in both OS and provides a end of line "character" which is system specific. It doesn't always work, and many of us don't have a way to test on more than one OS.

ok, 3FG's file loaded, so I looked at the learns. Treating them as a quad resulted in different length binaries, so I tried treating them as bi-phase instead, which mostly worked. The strings were all the same length now, but there were some double negative pairs in there, which puzzles me.

Here's the resulting binary where "?" signifies a double negative pair:

Rob,
I'm not seeing the problem with the decodes. I think the signal is close to:
{38k, 300, msb}<-1,1|1,-1>(1,-1,A:28,-82m)+

Of course, we do have to wonder why there are deviations of +/- 15% from nominal timing.

The Robman · Posted: Wed Dec 23, 2015 11:34 pm Post subject:

I didn't save my intermediate files but i did get double negative/off pairs where i put question marks. what binary did you get?

Also, I did too wonder my I was seeing +250 and +500 for On times and -350 and -700 for Off times.

I got the following decodes in hexadecimal where I divided things into D, S, and F, using
{38k, 300, msb}<-1,1|1,-1>(1,-1,D:11, S:8, F:8, -1, 1,-82m)+
If it weren't for the nova_Extra signal, we could simplify a bit more.

Dear 3FG,

I don't care about nova_Extra command.
How can i decode commands in bin file in order to upload in slingbox account?

I have also learned remote control with IRTrans in case is helpfull for someone.
Here is the .rem file
http://www.hifi-remote.com/forums/dload.php?action=file&file_id=13796

I really appriciate all of you for help.

I'll be traveling for a few days, so I it may be some time before I can work on this

The IRtrans learns help. They show a similar spread in the burst pair durations, but in detail the learned GC and IRtrans signals look different. So I'm inclined to think it is an ordinary biphase protocol with a lot of scatter in the learns.

Allan is my mistake the confusion in harmony account.
The remote PACE PVR is a mix from DZS3001 and new nova_xxxx commands.This hapen because the only way to learn the remote was to add commands in existing remote.So from this mix only nova_xxxx work in STB.
About nova_1,nova_2,Nova_3... was just the numbers of the remote 1,2,3...

I redid my decoding of the signals and I didn't get any double negative pairs this time. However, I did discover that there's a checksum bit at the end of the bit string and I need some help deciphering it.

If you look at the binary strings below, you will see that they all start with a "1" bit, which makes sense as it would not be a good idea to start a data string with an OFF bit, and they all end with a "0" bit, which also makes sense as it separates the leadout time. The third column below is the OBC byte, which is in MSB format, and the first of the 2 bits that follow is the checksum. For OBCs 0-9 it is simply the complement of the last OBC bit, but after that, I can't make out the pattern.

I have created an upgrade where the checksum is provided as a data byte, which is not ideal but will do until we can come up with a formula for it. But the generated bin files should work regardless.

Rob,
I believe these are toggle bits rather than checksums. When we look at the 40 distinct signals in the order they were taken, the ICT file shows the bit alternating for successive functions in 37 cases and staying the same in 2. I haven't tried to parse out the IRtrans file in detail, but for the first few signals, the IRtrans decodes are mixed compared to the ICT file. Some have the same toggle/check bit as the ICT file for a given function, but for other functions the bit is complemented.

So assuming tsaito gets your bin file to respond, it may be necessary to change the executor to provide a toggle capability.

The Robman · Posted: Sat Dec 26, 2015 11:06 am Post subject:

Good eyes, making it a toggle rather than a checksum is easier. I will update it.
