I'm sure this has been asked before, but I'm feeling really lazy, so before I start Googling, can someone tell me - yes or no, with even just a very brief explanation - whether it'd be possible to knock something together relatively easily with, say a Raspberry Pi 3, that could transmit a signal from a cable box to a smart TV* not very far away (~15' through what I think is not a heavy, load-bearing wall)?
I know there are existing, commercial HDMI transceivers, but they're expensive, and my use for one doesn't seem sufficient to me to warrant paying in the neighborhood of $200 for one. If such a thing isn't feasible, I'll just run a "temporary" cable until I get sick enough of it to pay real money to deal with it.
