What is NDI HX3?
On this week's Videoguys Live, James is exploring the world of NDI HX3! This technology enhances video streaming with low latency and high-quality visuals, all while using minimal bandwidth. NDI is perfect to use for live events, remote production, and more.
Watch the full video below:
In Today's Show We Will Discuss:
- What is NDI?
- How Do My NDI Devices Communicate?
- Full bandwidth NDI
- NDI HX – 2&3
- Benefits of using HX3
- Workflow examples of technology using HX3
What is NDI?
- NDI Stands for “Network Device Interface”
- NDI is used to transmit high quality, low latency video and audio signals over a local area network (LAN)
- Paired with a Network switch NDI Allows users to send video, control and Power to an NDI Device through a standard Cat6 Ethernet cable.
- It is widely used in broadcast systems, live streaming, video conferencing, and digital signage, among other applications.
How Do My NDI Devices Communicate?
- NETGEAR M4250 Pro AV Switches
- The M4250 Line of switches are designed specifically for AV over IP with NDI and Dante Presets available. Some switches even support ST 2110!
- Netgear’s Engage software makes changing profiles a breeze.
- Designed with Video in mind. They are rack mountable and quiet.
- The M4250 acts like a hub for all of your NDI Devices to communicate to each other
- NETGEAR is committed to AV over IP
Full Bandwidth NDI
- Full bandwidth NDI is the original version of NDI. It provides High Quality, low latency, frame accurate video and audio over IP.
|
Pros |
Cons |
|
High Quality – Closest to SDI quality |
High bandwidth required |
|
Low Latency – 16ms (1 frame) |
Can require more advanced network infrastructure |
|
Frame accurate syncing of Audio and Video |
|
NDI HX2
- Unlike Full bandwidth, HX2 uses H.264 compression to minimize the use of bandwidth on the network while still being able to send video over the network
|
Pros |
Cons |
|
Uses the least amount of Bandwidth possible |
Compressed video can add more latency |
|
Low latency 1-3 frames |
Compressing the video can lower quality |
|
Frame accurate syncing of Audio and Video |
|
NDI HX3
- NDI HX3 Is the middle ground between Full Bandwidth and NDI HX3. It offer compressed video using HEVC allowing for lower bandwidth usage than full bandwidth, while offering better image quality than NDI HX2
|
Pros |
Cons |
|
Less Bandwidth required than Full Bandwidth NDI |
Compressed video can add more latency |
|
Low latency 1-2 frames |
Compressing the video can lower quality |
|
Better image quality than NDI HX2 |
|
When Should I Use Full Bandwidth, HX2 or HX3?
- Use Full bandwidth when quality and lowest latency is of utmost importance. Just keep in mind that this does require more Bandwidth
- Use NDI HX2 When you do not have high bandwidth and want multiple cameras on the network. Just keep in mind this will have lower quality/ more latency
- Use NDI HX3 as a middle ground, when you have some restrictions on bandwidth, but still want to have good Image Quality.
