Looking for ideas.<br class="">
<br class="">
Think about multi-port USB hubs for laptops with only a few USB ports . . .<br class="">
<br class="">
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.<br class="">
<br class="">
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.<br class="">
<br class="">
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<br class="">
<br class="">
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!)<br class="">
<br class="">
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.<br class="">
<br class="">
Is this something that an R-Pi can be made to support with some HATs?<br class="">
<br class="">
In my mind, it should be fairly simple. It’s mostly just acting like a router, right?<br class="">
<br class="">
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.<br class="">
<br class="">
It’s just “audio over ethernet” and “video over ethernet”, no?<br class="">
<br class="">
What does that take? Is there hardware that already does it?<br class="">
<br class="">
<br class="">
(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.)<br class="">
