I read that the stream from NVX encoder to decoder is encrypted. Is it possible for someone to copy the rtsp address and paste it into a VLC player and see the stream? If this is possible, how would they do it? Besides copy/paste, is there a username/pw they have to add to the link? Can it be stopped?
Thanks, Chuck

Thanks, I was in a meeting today and our network group said that: 1- Crestron NVX doesn't work with Cisco 2-the network is set up?correctly and there were no lost packets over the network.? 3- they said they were able to copy/paste the rtsp address into VLC and watch the stream off the decoder?and the video was not blanking out every 8-10 seconds like it was out of the HDMI port on the decoder. I asked a couple times to confirm that they said they were looking at the stream off the decoder and that was the story they were sticking to.
This meeting included the CTO and also one of the "end users" of a new building for Comm Studies that I have designed with some nvx encoders/decoders so we can move content around between classrooms and studios.? The network group doesn't want NVX in there because they think they will have to manage it and it will take up a lot of their resources. They have already started planting ideas in people's heads that we shouldn't be using the "new" technology, and now they're trying to convince the techs in charge of the studios that this is unreliable and doesn't work.
Guess I have an uphill battle for the next 1.5 years when we do the install.

My first Cisco/NVX deployment had the same issue of the output blanking out and it wasn't until the switches were properly configured that this behavior stopped.
It could also be a bandwidth issue as I experienced on a recently poorly NVX design.
|
We have several deployments that use NVX on both Cisco SG series switches in smaller systems and Cisco Catalyst switches for bigger clients so the statement NVX does not work on CIso switches is not true.? We did run into an issue once that the internal IT Team had crazy QOS settings that was causing blac screens on the recievers.? Once they removed these settings video started working normally again.

Folks -?
After two decades in higher education, let me weigh in on NVX. Dealing with the NOC (Network Operation Center) at a few Universities, it is apparent that NVX is a non-starter on the school network. The only way to use NVX in Higher Ed is to create a private network with independent AV swithces which defeats the whole purpose of NVX and any input to any output.
I have resisted NVX products for this very reason and will stick to HDBaseT until my dying breath in the AV Industry. I know it sounds backwards but Crestron does not answer to the University NOC - however, I do.
Tell me your thoughts...

Your statement follows my belief that there is a technology that is suited for every environment. You are not wrong. ? I have integrated NVX in DOD and Other secure environments. There are methods that work in a secure environment. ?

Mike, exactly.
We're CONSTANTLY at odd with the network group, them saying Crestron doesn't know what they're doing (outside supply issues, they do).? We have this same issue using NDI for our video productions.
For a typical classroom, we won't even think about NVX. If we do us NVX in, say, a conference room or split room, we'll put all Crestron on it's own switch behind the processor's control subnet.

Sounds to mee more like school network administration is behind, not you. Network convergence is not that new anymore that this should be a reason not to integrate VoIP or AoIP into a corporate/school network. I think it?s more an issue off backwards looking network administration and lack of training… ? Just my 2 cents, Thorsten ? ? Folks -?

I am the last person to carry the NVX flag. However, I am an AV person with a strong background in networking.
You’re all correct IMO. NVX is a massive challenge. But if your networking config is correct, it won’t cause issues.
I might add that if you haven’t tried Netgear’s AV Line of switches, go out and watch the YouTube presentation they did a year or two ago. It’s about 1 hour in length. It’s a recording of a Zoom session. There is a Netgear Sales and Netgear Network engineer. They go through an entire demo and presentation. If you’re having trouble finding the right video, it’s the one with a split screen. The Network engineer is in the right pane and he has a strong French accent.
I know it’s Netgear and not what you have in your corporate/Higher Ed closets. But you can put them in for AVoIP closets attached to the rest of the network if you choose. They’ve made the config easy.
Mike, exactly.

I work for a University.? We've deployed NVX and other AV over IP devices (thank you Crestron supply chain issues) on the campus network with full support/assistance from our network engineering team.? NVX is not the problem.? Poor relationships within the organization are.? Build those relationships, then build the systems.

To come back to your RTSP stream on VLC player. The newer NVX boxes produce two different streams. One is the full bandwidth encrypted one that goes to the NVX decoder HDMI output. The second stream Crestron calls "image preview" and refreshes every second or two. This "image preview" stream can be accessed from VLC player or even a Crestron Touchpanel.? For full security it can also be turned off in the web interface of the encoder/decoder.
The statement that NVX doesn't work on Cisco is just false.
|
If the Cisco switches are "Meraki", I think you are going to have hard time getting NVX work.
|
I've had NVX? (1G) and 10G (SDVoE) deployed on Meraki and while I'm really not a fan of Meraki for a number of reasons (for one I hate switches where you have to use a web UI much less a cloud-based web UI to configure) and my client that most recently adopted
Meraki is having regrets for similar reasons, with the settings correct it does generally work.?
First NVX-on-Meraki project was a couple years ago and the client hasn't mentioned any issues, the first? SDVoE one is an ongoing install but video is passing without any noted issues.

These are two groups that are being jammed together like nuclear fusion and the culture clash is sometimes the worst part.
Often IT people are just as oblivious to AV as AV people can be to IT and don't appreciate someone telling them how to do their job. Add to that the fact that most IT people have never had to deal with and aren't (historically) trained to deal with? the realities
of high bit rate multicast...and therefore virtually no network is properly configured to support it until the issue gets pressed... it's human nature to blame the things you don't understand (see also: Salem witch trials)
A lot of times all it takes is someone who can build the bridge between the two groups and confidently explain the "why" as much as the "what" and "how" rather than making what appear to be blind demands. More therapy and conversation than demands and duels...
Getting the client in the right mindset is also important...for one of the systems I designed I started laying the network expectations foundations about a year before we even finalized the design, much less started installation -- what that knowledge the client
was able to ensure that what they were procuring on the network side meshed with AV expectations so that wouldn't be an unpleasant surprise. But I also had discussions with the CIO e.g. "this is what I think is best for you and what I'd like to do but your
team needs to be on board with X, Y, Z because A, B, C, if that not possible here's another direction we can go..." -- if I just rolled in and was like "gimme X, Y, Z or this thing you bought won't work" I probably would have been escorted from the building...

“A lot of times all it takes is someone who can build the bridge between the two groups and confidently explain the "why" as much as the "what" and "how" rather than making what appear to be blind demands. More therapy and conversation than demands and duels...” ? Exactly. Since i?m coming from corporate IT and being now into AV, I know both worlds. Don?t just fill out a change request and wait for it to be executed, but sit together and explain the bigger picture. Understand the requirements and concerns of both worlds and work out a solution collectively. This takes some more time at the beginning, but will pay of later. ? Cheers, Thorsten ? ? ?
