What is NDI?

Network Device Interface (NDI) is a high performance AV over IP standard that allows anyone to use real time, ultra low latency video on existing IP video networks. The NDI open protocol enables professionals to share video through a local area network (LAN) with video-compatible devices. With a single ethernet cable connection, professionals can merge all stages of production from start to finish. That way, all production tasks and processes will be united, so accomplishing a creative vision will be simple. With the NDI 5.5 tool-kit, users will also be able to connect any audio device as an NDI source with NDI’s Audio Direct tool. This adds audio over IP to NDI’s revolution. Here’s a list of our NDI compatible cameras:

• BG-ADAMO-4KND Live streaming PTZ camera supported by NDI|HX 3
• BG-4KND-12XUHP Live streaming PTZ camera Supported by NDI|HX 2
• BG-UPTZ-ND Live streaming PTZ camera Supported by NDI|HX 2
• BG-ND-XHSRP Live streaming PTZ camera Supported by NDI|HX 2

What is NDI High Bandwidth?

The NDI high bandwidth standard provides users with great quality and very low latency. Simply put, users can expect a high quality output without any lagging, loading or freezing. The downside to high bandwidth NDI is, this standard does not compress the bandwidth of the inputs so it uses a lot of bandwidth. Using full bandwidth in a local area network (LAN) can cause high latency for any other device connected to that network. When using the High Bandwidth standard, it is recommended that users create a vLAN for their devices. A vLan is a virtual local area network that is isolated from other workspaces on the network, that way you can manage your bandwidth consumption.

What is NDI|HX?

NDI|HX is the first version of NDI’s compressed bandwidth standard. To address the bandwidth problem users were having with the High Bandwidth standard, NDI implemented bandwidth compression. Simply put, the HX standard reduces the bandwidth needed to transmit a given amount of video/audio data in a given time. Also, this reduces the time needed to transmit a given amount of video/audio data in a given bandwidth. Overall, this allows for NDI devices to be on a LAN without draining bandwidth.

What is NDI|HX 2?

NDI|HX 2 is an updated version of NDI|HX 1. NDI|HX 2 also compresses the bandwidth, but is more efficient than NDI|HX 1. With compressed bandwidth, users can have more devices on their LAN without running into latency issues. NDI|HX 2 provides good quality output, low bandwidth and medium latency. The main difference compared to NDI|HX 1 is that HX2 is truly a native NDI stream - all the way from the source device to the destination. This means it is a 'cleaner' implementation than HX1 and can potentially be more reliable, provide lower latency and give a more flexible connection which shares all the usual features of NDI.

What is NDI|HX 3?

NDI|HX 3 is an updated version of the HX2 standard. The difference is, HX3 provides a better image quality and lower latency than HX2. NDI|HX 3 also uses slightly more bandwidth than NDI|HX 2, but the increase in bandwidth is not significant enough to be an issue. There are a limited amount of NDI|HX 3 compliant devices due to a hardware limitation most NDI|HX 2 compliant devices have. Overall, NDI|HX 3 is the latest update to the standard and offers the best features.
