SDVoE system advice - routing without PC
Hello,
is it possible to do something like on picture shown bellow with SDVoE system?
- Whatever you put into Input X, must be routed to all output Xs
- If you plug 2 or more cables to input X, switch must be able to handle this somehow and not cause any errors - ideally it should route the latter connected cable
- Switch with at least 12 SFP ports
- Should work without PC, PC only for configuring the switch
The idea is: we have 1 big monitor (Output 1) connected over SDVoE Tx/Rx to a PC (Input 1). In the same room we also have a lamp camera and HDMI patches for laptops (Inputs 2). All this will be also connected over SDVoE Tx/Rx to 2x display and 4K capture card.
So what I want to do in short is to split the ports into 2 or more groups of "Inputs" and "Outputs" where input would be routed to all outputs in that group.
Thank you!

Dear AKC_Alois
Better late than never (I'm here):
split the ports into 2 or more groups of "Inputs" and "Outputs" where input would be routed to all outputs in that group.
Not a specific AV question really.
The generic IT networking answer would be to configure and operate multiple VLANs with dedicated Access Ports for each group. This is logically like operating small standalone, unmanaged switches that would allow plugging ports on demand.
Very vague what else you require - like access to these lamp cameras (sorry I had to search for understanding what these are 8-) , so these are known as Bulb Cams, haven't seen many of these with industry standard network protocol support), access to the internet, access to other devices on the LAN, ...
A "bigger picture", some make and model data of these cams,and a drawing (beyond of what you already asked, this part is clear to the readers) might be helpful to assist further.
Time for some more brainstorming?

Hi Kurt,

this is clear, just create VLANs and that's it. My question is, does this also work reliably with SDVoE encoders and decoders? I only tested point to point connection with SDVoE and switch-based multicast software solution with SDVoE is from our parnter - we have very limited knowledge about how this work.

Oh, my bad. Instead of lamp camera you can put another PC. Lamp camera in this industry has video port out (typically SDI or HDMI with possible 1.3 or 1.4 HDCP protection) - again, connected over SDVoE encoder.
I will try to make a drawing so it's maybe a bit more clear what we want to do.
The idea is: we have 1 big monitor (Output 1) connected over SDVoE Tx/Rx to a PC (Input 1). In the same room we also have a lamp camera and HDMI patches for laptops (Inputs 2). All this will be also connected over SDVoE Tx/Rx to 2x display and 4K capture card.
FWIW, I agree a diagram would be useful.
So really three outputs? ("big monitor", "2x display", and "4K capture card")?
I see 3+ inputs ("PC", "HDMI patches", "Lamp Camera") - how many HDMI patches are there?
I am guessing that the Lamp Camera is wifi-connected. If so, how does the wifi stream reach the switch?
If you plug 2 or more cables to input X, switch must be able to handle this somehow and not cause any errors - ideally it should route the latter connected cable
This sounds like you are expecting the most recently connected input to be routed to all outputs???? So you always want one input connected to all outputs? Never (for example) the PC displayed on the big monitor, but the lamp camera routed to the capture card?
Overall, this sounds like you are trying to create the equivalent of an HDMI switch. Is that correct?
I am thinking that using an HDMI switch would be a more cost effective solution. You can find decent 8x8 matrix switches for about $700 USD. You could add an IP decoder to HDMI for about $200 USD, so less than $1000 USD total.
I do understand that SDVoE does include Matrix Switching as one of its use cases. But it looks like it would be lot more expensive.
AKC_Alois In case you don't want to go the (in my opinion the least expensive, exactly as per your design drawing - but know-how dependant) way with "hard" defined VLAN access ports according to your design intention, some vendors of SDVoE encoder and decoder (aka. transceivers and receiver) boxes also offering SDVoE network controllers allowing to dynamically configure groups using a WebUI at an additional cost. Keep in mind not all appear per-se purely SDVoE "de-facto standards" based, many depend (eg. for simple device control and discovery) on vendor specific functionality. At least this is what the various vendors product descriptions and data sheets state.
Not sure a basic capture card (requiring a powerful PC for full 4K@60 4x2x0 or a slightly compressed 4x4x4) is able to do - again please look at the SDVoE Signal Processing systems (Transceivers or Encoders) on https://products.sdvoe.org/avcat/ctl18883/index.cfm?category=signal-management-processing
