Hi! Today we are going to talk about NV Series networked video endpoint peripherals
00:12
that allow native video distribution in the Q-SYS Ecosystem.
00:15
Or, in layman’s terms,
00:16
we can now route HDMI video and audio over the network! Yay!
00:20
Audio, video and control, here we come!
00:23
Now whether you are transporting that audio and video from one side of the meeting room to the other,
00:28
or all the way across campus, as long as they’re on the same network, and a part of your Q-SYS design,
00:34
you can do it!
00:35
In this video series we’re going to cover the basics of video formats and protocols,
00:39
we’ll look at the ins and outs of this device and the codec,
00:42
as well as how to wire it inside the Q-SYS Designer software.
00:45
And because we’re talking about video,
00:47
you better believe we’re gonna jam this series with all the movie quotes we can!
00:51
So hold onto your butts…
00:53
‘cause we’re turning it up to 11.
00:55
The first thing to know is that there is only one model in the NV Series, the NV-32-H.
01:02
We don’t have a separate “encoder” model and a “decoder” model,
01:05
because this single unit is software definable,
01:08
which means that you can configure it as an encoder or decoder within the software.
01:13
It is “The One.”
01:18
If you look at the back of the unit you’ll notice it has three HDMI inputs and 2 HDMI outputs.
01:24
When the unit is set as an encoder,
01:26
you’re primarily bringing HDMI video and audio into the Q-SYS Ecosystem.
01:31
However, you can also use one of the HDMI outputs as a display for these local HDMI inputs as well,
01:38
for use in a confidence monitor scenario.
01:41
Likewise, when the device is set as a decoder,
01:44
you’re primarily decoding HDMI video sources from the network to one or two displays,
01:50
again depending on your desired resolution.
01:53
However, in addition to decoding video sources from the network,
01:57
you can also switch to one of the three local HDMI inputs on the device for local switching options as well.
02:04
If you haven’t caught on yet, this one model is incredibly versatile…
02:08
… but don’t worry, you can cross the streams as much as you want.
02:12
I thought you said crossing the streams was bad.
02:14
No, not in this case.
02:15
The other really cool thing about the NV Series is its codec —
02:20
or, the way it handles compression and decompression.
02:22
If you know anything about video distribution, especially for the meeting room,
02:26
you know that you’re always trying to strike a gentle balance between quality, bandwidth and latency.
02:32
And, you probably also know that sometimes IT personnel are cautious
02:36
about putting video on the network for fear of it gobbling up bandwidth unnecessarily.
02:42
However, the NV Series uses QSC’s proprietary video codec called Shift,
02:48
which dynamically adjusts the network bandwidth required based on the content being displayed,
02:53
which affords massive network bandwidth savings for most common meeting room installations.
02:58
You see, shift codec doesn’t necessarily re-transmit every single pixel in every single frame
03:04
if that content has not changed.
03:06
Think about a meeting in which you’re displaying a graph in a PowerPoint presentation –
03:10
– that graphic isn’t going to change for a while …
03:13
in a really boring meeting, maybe a very long while!
03:16
Who wants to read first? I'll go... so, this shows...
03:23
So shift provides incredibly clear clarity of content while minimizing the bandwidth required,
03:28
and you can see the change in that bandwidth in the control panel too.
03:32
However, shift looks incredible with full motion video as well,
03:36
it just means the system will require higher bandwidth during that time.
03:40
Finally, it’s worth noting that all of the video routing and control is happening at the software layer
03:46
within the Q-SYS environment –
03:47
– there’s no separate hardware endpoint manager or control processor
03:51
because it’s all managed by the Q-SYS Core.
03:54
In the next video, we’ll be going over the basics behind video formats, HDCP and EDID,
04:00
along with a few specific resolution and stream counts from each NV-32-H peripheral.
04:06
Thanks for watching and we’ll see you next time!
