This stb is made by a small company, I got the ir using urc 8910, but the ir.exe cannot recognize the protocol. Then I gonna to decode it. Following the instruction I got code1.txt, code2.txt, code3.txt, found it complex to go further, could you do me a favor to get the device upgrade files? It would be very appreciated to show me the process, thanks in advance!
The file link is as below:

I feel like I've seen this protocol, or something similar, before. It's similar to NEC1 but has 3 bytes of fixed data and 2 bytes of variable data and the leadin burst is repeated as a mid-frame burst after the 3 fixed bytes:

freq: 37.9 kHz
leadin: +3420 -1710
leadout1: +570 -54150
leadout2: +570 -100320

data:
00010010 01110010 11000010 00001100 00001100 = 0
00010010 01110010 11000010 00001100 10001100 = 1
00010010 01110010 11000010 00001100 01001100 = 2
00010010 01110010 11000010 00001100 11001100 = 3
00010010 01110010 11000010 00001100 00101100 = 4
00010010 01110010 11000010 00001100 10101100 = 5
00010010 01110010 11000010 00001100 01101100 = 6
00010010 01110010 11000010 00001100 11101100 = 7
00010010 01110010 11000010 00001100 00011100 = 8
00010010 01110010 11000010 00001100 10011100 = 9
00010010 01110010 11000010 00100010 11110010 = CH-
00010010 01110010 11000010 10101010 00001010 = CH+
00010010 01110010 11000010 00001010 11101010 = Power

so the format is:
once: leadin, fix1, fix2, fix3, leadin, var1, var2, leadout1
repeat: leadin, leadout2

Does it ring any bells to anyone?

Thank you Rob, it should be exactly what you thought. And I am a newer to use the PB and KM, can anybody help to send me the right files? It would be better including the PB and KM files.

Here's a first attempt at a protocol for you:
http://www.hifi-remote.com/forums/dload.php?action=file&file_id=8335

And the KM file is here:
http://www.hifi-remote.com/forums/dload.php?action=file&file_id=8336

Here's the upgrade formatted for the URC-8910:

Upgrade Code 0 = 68 00 (Cable/0000) DVN STB1 stb (KM v9.19)
FF 00 B1 12 72 C2 0C 0C 0C 8C 0C 4C 0C CC 0C 2C
0C AC 0C 6C 0C EC 0C 1C 0C 9C AA 0A 22 F2 0A EA
End

Upgrade protocol 0 = 01 FF (S3C8+) DVN STB1 stb (PB v4.02)
44 8B 32 8B 16 8F 44 08 08 01 1D 02 12 01 1D 01
09 69 BC 07 1B 03 77 FF FF FF 19 77 77 F6 01 46
B0 12 B0 13 C6 1C C3 F0 46 29 01 8D 01 46
End

Glad to receive your reply, but seems it not work. I checked the KM file and found that maybe the device2 could be 114 not 144, then I use the updated one to test, it doesn't work neither. Did you get any other suggestions?

You're right, it should be 114, silly typo.

It sounds like your STB may have a separate command for "+10".

Another possibility is that there is a command that switches from single-digit to double-digit channels entry. I have usually seen such buttons labeled "-/--"

Did you learn either of those buttons?

Actually it's not the case what you said. My STB got no "+10" or "-/--", if I continuously press two numbers in two seconds, it will combine them as one channel, it just distinguish the channel by pressing continuity. So what shall I do for this situation?

You may have a slow STB that can't handle a fast macro? You can try adding a pause protocol and putting a pause between each digit.

I am not familiar with pause protocol, but how to add the pause protocol? Do you got some guide files or examples? Thanks in advance

When you use the STB remote to enter channel 12, what do you see on the screen? When you press the 1 do you see "1" on the screen? Then what happens when you press 2? Does the "1" become "12"?

Then, what happens when you do the same thing using your JP1 upgrade?

It sort of sounds like the REVERSE situation, where the OP cannot press successive buttons FAST enough.

dillon, how do you change channels using the ORIGINAL remote?
