So I've been busting away for a couple of hours trying to figure out how to build a remote from scratch for a JP1 device, based off the original remote. I don't have any JP1 remotes to learn the original remote nor do I have the cable to extract it. I'm just trying to assemble what I need so that I can plug the info into my slingbox solo.
I tore down the original remote and found the following key components.
IC - http://www.szkexinda.com/soft/TC6456BA.pdf
TF
TT6222-1
0805
Crystal
H
455E
I've also received a PDF from the manufacture for the remote codes but I can't quite interpret it.

Also I took pictures of the torn down remote.

What is the device that you're trying to control?

| From what I see, that chip makes kinda like an NEC2 code. |

I assumed NEC1 for the upgrade that I created. When echos reports back as to whether it works or not, if he says that the buttons don't repeat properly, I'll try changing it to NEC2.

That is because NEC 1 and 2 repeat differently.
NEC1 repeats by repeating the whole 32 bits, NEC2 by sending just one bit. That datasheet shows the repeat bit being sent. |

You've got that backwards. NEC2 repeats the whole string, NEC1 just repeats the leadin and leadout with no data bits.
