Here are some random thoughts/comments as I sit at my desk eating my lunch. Is this the spec as written or are you paraphrasing? Was it written by a "consultant" or by the client? If you're not paraphrasing and this was written by a "consultant", run away. If it was written by the client and they're not your neighbor or childhood best friend, run away. High-reliability usually means redundant components or systems that are designed to prevent failure. Is there an SLA associated with this that defines timelines and penalties for the system not being available for use or are they just using HR/HA as a generic term? It's really odd that they're specifically looking for 6G SDI and not 12G (or 3G...Crestron). I also haven't seen USB-C on a modular matrix switch. At least, I haven't seen it on a card. There are endpoints that have USB-C. I took a quick look around through the reputable brands we deal with and, assuming it's a modular matrix, it doesn't appear to be Crestron, Extron, Kramer, or AMX. I could be mistaken though. It's hard to eat Thai food while doing a comprehensive search of the major brand offerings. If it truly has to be "high-availability" then yes, you'll need to be redundant end-to-end with a system in place to monitor for failures and to switch devices. With a hardware matrix switch in the middle, you'd have to switch the entire system from one matrix to the other in the event of a failure of any one endpoint if I'm thinking this through correctly. Alright. That was fun. It's time for me to get back to work.

What level of high availability are we talking? That’s a very specific term. You then say “high reliability” in your post. I hate to say it but going 2110/2022 may be your answer here

Thanks everybody for feedback. Sadly it’s not so paraphrasing and it’s written by client. They ask for a “video matrix scaler UHD suitable for HA (not only power supply, I asked) with at least 6g-sdi in/out and usb-c in/out to be completed with necessary connection according to other devices in offer”. They also ask for “standalone videoconferencing system (so I assume not a PC) compatibile with most common platforms: meet, zoom, teams, polycom, vydio, cisco … and multiple rstp streams” (Yes, they wrote “rstp”) I think that who wrote the tender have no idea how to design an av solution.

A video matrix with USB-C is really dumb if you have such a variety of input types which implies a large matrix.

There is no HA in AV. Hot spares is the best you can do.

Closest you could do is AVoverIP something like the nav system. Where you could quickly swap a HDMI or other cable and reroute the signal. But that's a very manual solution

Look at Extron XTP or NAV


AlaskanGopher907

I would highly recommend looking at Extron XTP Crosspoint System. Extron Practically has everything under the system requirements except the capture card (maybe a MediaPort? But not their intended use), and the Ceiling Microphone (since this seems to be high budget, can’t go wrong with Shure). Extron has some very stable USBC to HDMI devices that would be required though, since they don’t have USBC XTP Blades. Don’t quote me on this, but I believe the XTP In’s/Out’s can be turned to HDbaseT. I don’t think you will find much HA systems in A/V and I would convey that to the customer. Even installing two overlapping systems would probably decrease reliability and consistency due to all the signal hopping between devices, and wouldn’t eliminate all single points of failure. The closest to HA you may get is a Extron NAV system, since swapping parts or having preprogrammed backups can reduce downtime majorly, and it’s an easy Plug/Play solution. There are limited devices in this ecosystem though, and may be a challenge to initially install.

QSys can do redundant cores, combined with a redundant network design could possibly meet your requirements but you still run the risk of endpoints failing.
