I'm trying to figure out if it's possible to replicate IR commands without using arduino, only with an IR receiver and an IR emitter (like tsus4300, teft4300) to transport the remote commands codes from my bedroom to my living room where there's the pay tv SAT decoder.
I've already found a way to transport the SCART rgb video using an utp cable but, since this method uses only 6 of the 8 conductors, my idea was to use the last 2 conductors to transport the signal to pilote the ir emitter.
My idea is something like like this:
The circuit is powered when the usb give out 5V( aka the tv is powered on ) and the ir receiver, acting as a transistor, allow current flow only when an ir light is detected, powering the ir emitter with the same frequency of the iput IR.
Assuming the receiver and emitter works at the correct ir wavelenght of my remote control, is this setup going to work?
Ok, before reading that pdf i just want to remember that i don't want to read the ir signals from an arduino, so i'm not going to play with sketches.
The idea was just transport the ir signal as-is, without decode/encode/modulation etc, like a long pipe full of mirrors, or like an optical fiber.
Ipotetically, this has to work with every ir remote control as "the goal" is just to transport an analog signal and emit with the ir emitter, totally ignoring the transmitted codes.

Pay sat receivers often have a built in facility for this, all you have to do is purchase a 'magic eye'.
What you want to do is feasible but will require learning some electronics, one of the arduino shield examples may be an easier solution.

Making it work for all remotes may be problematical.
Some use widely different carrier frequencies with B and O being the king at about 500 KHz
Yes, just search for IR repeater or extender on amazon or eBay. Just be careful about the frequency range supported, as the quoted specs can be inaccurate. Look for at least 30->58kHz coverage and be prepared that some devices may not work well. Issues typically arise for protocols like RCMM & XMP and also anything that is in the 55kHz+ range. As mentioned previously, there is seldom a solution covering the less common B&O devices that run at 455kHZ.
There are also solutions that will make use of wireless or existing coax / utp cables. Just make sure you can return it if it doesn't work out.
