Helping Decoding Chinese Remote

[braddlac]

I'm been reading up on this all day and have made some progress, but this signal seems very difficult for my first try. I mapped the remote with IR Scope and each frame has a lead in and there is a mid stream burst.

The ultimate end game is to convert this to a slingbox .bin file.

If anyone has time can you please take a look at this? Any help is appreciated.

I don't think we've seen this IR protocol before, or at least I don't know how to find it. The lead in pair is repeated mid way through signal, and the signal repeats by a kind of ditto. Here's one way of apportioning the bits:

Code: Select all

IRP = {38.0k,182}<3,-3|3,-6>(20,-10,T:2,D:6,F:8,S:8,20,-10,~T:2,D:6,~F:8,3,^108m,(20,-20,3,^108m)*)   T=3

Here's the decodes. I've rearranged the order to make the OBCs ascending.

Code: Select all

I don't have time to work on an executor right now, but I think it will fit in the Slingbox OK.
