Live Video HDMI Capture - Multiple Servers

Recommended Posts

Hi there!

 

I'm trying to find out some information on HDMI capture, but I can't seem to find the answer after trawling through the forum. I was hoping someone might be able to help me?

 

Our company carried out an install at a site with 2 studios (both identical). Each studio has:

 

9 Projectors projecting onto 3 walls.

3 Watchout Display Servers (Each connecting to 3 projectors)

 

1 Watchout Production PC which manages both studios

 

The client would like to plug a laptop (standard HDMI Input) into the system and have the feed displayed on each wall. Each server feeds 3 projectors, which covers one of the walls. 

 

My Question is, can i have a single HDMI capture card in server 1, and then have that image output from servers 1, 2 and 3 at the same time? Lag isn't a concern as it's pre-programmed video content (as long as all 3 images are in sync).

 

If not, do I need to have a capture card in each server, and then split the HDMI signal between the 3?

 

We're currently looking at using the Black Magic HDMI Capture card. hoping this is compatible:

Server Spec:

Intel Xeon E3-1275

64GB DDR4 2133 RAM

FirePro W7100 Graphics

2x 960GB Samsung Enterprise SSDs

Windows 7 Pro

 

 

 

Thanks in advance for any advice you can give!

Hi,

If you use capture cards, you do need to split the signal and feed every server with the same signal using 3 capture cards.

Another option could be to use a HDMI > NDI converter box and then use the NDI signal instead.

This works with the current version of WATCHOUT.

We actually stopped selling and using Blackmagic capture cards due to lack of support and unreliable drivers. Datapath would be a better option. If latency is not an issue, you could also use USB3 capture devices like the INOGENI 4K device.

Best regards

Rainer
