This exists. I have used it before. You looking to send what kind of signal?1080p or more?
I’m shooting in the dark here wondering how to solve this. Looking for ideas.
Think about multi-port USB hubs for laptops with only a few USB ports . . .
A guy I’ve been talking with said he's looking for something like that but plugs into the ethernet, not USB, and uses PoE for power.
It’s basically a break-out box that uses wired ethernet to send data to some remote spots about 100 M away through a 1GB switch.
His requirements include: audio (mic, headphone), USB video in, USB video out, some digital I/Os to turn lights on and off, a couple of spare USB ports
The video is streaming 4k, probably H.264; he has the camera and a display device, and both work via USB. (There’s a reason he has chosen USB!)
I don’t know if there are simple chips in these sorts of USB “splitters” or if they have a CPU like what’s in a Raspberry Pi.
Is this something that an R-Pi can be made to support with some HATs?
In my mind, it should be fairly simple. It’s mostly just acting like a router, right?
A separate audio stream on the ethernet could go to a USB port with a common “USB Sound Card” where the mic and headphone can be connected.
It’s just “audio over ethernet” and “video over ethernet”, no?
What does that take? Is there hardware that already does it?
(Dante has a small A/V board to embed in equipment, but you need one on each end of a one-way circuit, meaning 4x per connection, and he needs up to 8 of these channels.)
