Meetings in 4 Rooms must be recorded & live streamed with DSK on EACH with ONE operator
on Jul 6, 2017 at 2:09:48 pm

I am needing to develop a system that will record 4 rooms (one camera each), record & live stream, and downstream key each output. The trick is, I can only have one operator.

I am thinking of getting 4 ATEM switchers with 4 Hyperdecks.

Can I hook up 4 ATEM switchers to one computer or would I need 4 computers (with a KVM)?

Any advice would be appreciated.

Hi John,

How far apart are the rooms?
How about audio?
In terms of downstream key, is it a logo or bug?
Does the facility have enough bandwidth for four live streams?

Rooms are in adjacent office rooms in a hallway. Very close.
Audio will be recorded via Shure MXA910 in each room. DSK is a lower third graphic describing the meeting name.
Bandwidth should not be a problem as this is a government building.

Hi John,
How about one computer with a decklink quad, and some software?
This thing could do it:
https://www.videotoolshed.com/product/recorder/
It's an FFmpeg front end. I can adjust it to add the DSK, and configure it for your streaming.
(Not sure if you stream to YouTube or elsewhere.)

This way you're done for a fraction of the money, with way less hardware.

Why not add the DSK at each of the cameras?

This DSK is actually more expensive than the ATEM switcher.

Newtek TriCaster would be very well-suited to this project. The only caveat is that you can only encode one stream at a time, except with TC1 model which has 2 encoders. Meaning, you would have to take 2 video outputs from TriCaster into stand-alone streaming encoders for additional streams. Or could use a PC with a dual-input streaming card such as Osprey perhaps.

Newtek NDI is video over the network, with no latency and excellent quality. Newtek just introduced the NDI Connect Spark. It's a $495 box that takes in an HDMI source and converts to NDI - plug unit into the network and video travels to any device on the network (SDI version also available). Put a Spark in each room, and no need to run video cabling all over - use existing network jacks.

Using TC1 (or other TriCaster model with Advanced Edition upgrade), you would have 8-16 NDI inputs available over the network (plus HDMI or SDI inputs depending on model). All 4 cameras can come in via NDI, or physical connection. If you don't want to use the venue's network, pick up an inexpensive network hub ($50) and run your own Cat-6 between rooms to connect all sources to TriCaster.

TriCaster has 4 M/E buses. Route 1 camera to each bus, and use the M/E Keyers to add unique graphics to each source. There are 4 of these Keyers (DSKs) per M/E. TriCaster can record up to 4 sources at once to the hard drive as high-quality .mov with 4:2:2 quality, plus 2 additional sources as H.264 format.

The TC1 would be able to take in all 4 cameras either as SDI or NDI, add appropriate graphics via DSK to each source, record each source, and stream 2 of those sources via internal encoders. There are 4 SDI outputs - configure sources 3 and 4 to output as SDI and route to external streaming encoder (about $500-1000 per unit, various vendors).

TC1 is $15k. Could pull this off with a TC Mini at $8k (Mini HD4 with Advanced Edition software added). Mini would encode 1 stream internally, route 2 unique HDMI outputs to external encoders, and for 4th stream...NDI to another computer which would stream that source.

None of these are inexpensive, but they are ideal solutions to do what you need to do.

Since Newtek allows other vendors to use NDI without charge, it is gaining rapid adoption. For instance, vMix and other software switchers are now integrating NDI into their products. You may be able to build your own PC with vMix and add appropriate video cards to the system and achieve similar results to TriCaster workflow. Would require vMix 4k or PRO version. This would be less expensive than TriCaster if you are comfortable with the "build your own" workflow.

I will also add that PTZ camera manufacturers are now adding native NDI output to their cameras. Panasonic and PTZ Optics will both be offering NDI soon, and Newtek just introduced their own camera, the NDIHX model.

NDI offers a one-cable solution with NDI PTZ cameras. ONE network cable can offer Power, Video, and Control of the PTZ camera! Imagine one operator being able to view, control, record, and stream programs from 4 rooms simultaneously...

The future is here!!!
