00:00:00.000 --> 00:00:03.587
N D I (Network Device Interface) carries video and

00:00:03.646 --> 00:00:07.651
audio over standard Ethernet. It started at NewTek and

00:00:07.709 --> 00:00:11.146
is now stewarded by Vizrt. On a local network

00:00:11.297 --> 00:00:14.489
it gives you full-resolution sources with low latency and

00:00:14.559 --> 00:00:17.995
automatic discovery — sources appear on the network without

00:00:18.042 --> 00:00:21.571
manual addressing. WAVE treats N D I the way

00:00:21.618 --> 00:00:24.601
it treats every transport: as a thin adapter over

00:00:24.683 --> 00:00:27.852
one Media Engine. You ingest N D I on

00:00:27.887 --> 00:00:30.569
the L A N where it belongs, and deliver

00:00:30.638 --> 00:00:33.263
over whatever transport the far end needs — S

00:00:33.356 --> 00:00:37.024
R T, Web R T C, H L S,

00:00:37.175 --> 00:00:40.844
Mock — through one A P I. What N

00:00:40.914 --> 00:00:43.921
D I is good at. - Low latency on

00:00:43.956 --> 00:00:47.706
the L A N. Sub-frame on a well-provisioned network,

00:00:47.880 --> 00:00:50.190
which is why it is common in live production.

00:00:50.886 --> 00:00:54.706
- Full-resolution sources. High quality with light compression for

00:00:54.764 --> 00:00:59.942
local links. - Automatic discovery. Sources announce themselves; you

00:00:59.988 --> 00:01:04.702
do not hand-configure IPs. - Standard infrastructure. It runs

00:01:04.749 --> 00:01:07.837
on the Ethernet you already have. N D I

00:01:07.987 --> 00:01:10.948
is a local-network protocol. WAVE's job is to take

00:01:10.983 --> 00:01:14.373
it off the L A N cleanly. Network notes.

00:01:14.779 --> 00:01:17.542
N D I uses multicast D N S for

00:01:17.589 --> 00:01:20.503
discovery and a range of T C P/U D

00:01:20.642 --> 00:01:23.603
P ports for transport. On a managed network: -

00:01:23.696 --> 00:01:28.538
Allow multicast D N S (U D P 5353)

00:01:28.781 --> 00:01:31.672
so sources can be discovered. - Open the N

00:01:31.730 --> 00:01:34.911
D I discovery and transport ports (commonly 5960 to

00:01:35.318 --> 00:01:42.562
5970) between sender and receiver. - Prefer wired Gigabit;

00:01:42.887 --> 00:01:46.498
ten gigabit if you are carrying several full-resolution sources.

00:01:47.311 --> 00:01:50.933
- For constrained links, N D I's high-efficiency mode

00:01:51.003 --> 00:01:56.077
trades some quality for much lower bandwidth. Ingesting N

00:01:56.170 --> 00:01:59.095
D I into WAVE. Point WAVE at an N

00:01:59.177 --> 00:02:01.452
D I source and choose how it leaves the

00:02:01.487 --> 00:02:04.691
building: The N D I adapter lives at N

00:02:04.773 --> 00:02:08.000
D I dot wave dot online. The same pattern

00:02:08.058 --> 00:02:10.972
holds for the other broadcast transports — the source

00:02:11.007 --> 00:02:16.382
changes, the A P I does not. Troubleshooting. -

00:02:16.591 --> 00:02:20.423
Source not appearing: check that multicast D N S

00:02:20.492 --> 00:02:23.267
is allowed and the discovery ports are open between

00:02:23.314 --> 00:02:27.795
machines. - Latency or stutter: use wired Ethernet over

00:02:27.853 --> 00:02:31.360
wireless, and check for congestion; move to ten gigabit

00:02:31.418 --> 00:02:34.715
if you are carrying multiple sources. - Audio sync:

00:02:35.098 --> 00:02:38.105
keep sample rates consistent and carry timecode where you

00:02:38.163 --> 00:02:42.935
have it. Where it fits. N D I is

00:02:42.981 --> 00:02:46.244
the first mile on the L A N. WAVE

00:02:46.302 --> 00:02:48.588
is the A P I that carries that first

00:02:48.658 --> 00:02:52.118
mile to anywhere — and prices, settles, and meters

00:02:52.164 --> 00:02:55.090
the delivery through the same gateway every other transport

00:02:55.160 --> 00:02:59.421
uses. - Transports and protocols: docs dot wave dot
