Wide Area Network Connection for NDI

 

This unique service allows your NDI equipped facility to connect to a global network of NDI sites

 

NDI Cloud provides NDI service discovery forwarding across wide area networks (including the internet), and also offers multiple transport modes to suit available bandwidth between sites. The NDI Cloud Intermediate Protocol compensates for the high latency and lower bandwidth as your NDI streams leave your local gigabit LAN and join a wide area network.

 

Whilst the required bandwidth is massively reduced, NDI Cloud maintains good quality picture and sound even when connecting over long distance, high latency links, such as transatlantic connections.  NDI.Cloud even supports Fill and Key alpha channel NDI sources.

 

Remote NDI sources are presented in your list of NDI devices, alongside your local devices, making connectivity trivial and seamless.

 

Using the NDI Cloud collaboration hub with your web browser, you can manage site groups and memberships. In addition to managing inter-company connections across multiple sites, Sienna  NDI Cloud allows completely independent production facilities to setup ad-hoc connections between themselves for remote contributions of interviews, and other talent-oriented and geographically limited production workflows.

 

With NDI.Cloud the cloud component is just used for service discovery and configuration - your video flows point to point between your own sites, and never flows through ours or any 3rd party server. This gives you content security (by using an encrypted VPN between your sites) and also ensures minimal latency. NDI.Cloud is the enabler of a true wide area network between your own sites.

Features

 

NDI is a TCP based protocol designed for use on a local area network, typically within a single subnet.  Bandwidth per stream can be 100MBit/sec for HD.

 

In order to carry the content of NDI sources across wide area network,

NDI.Cloud performs 4 major roles:

 

* Site Grouping and Discovery - so your various sites know about the others

 

* NDI Service Discovery Propagation - Your local NDI sources are re-advertised at each of the remote sites, so they can be selected anywhere.

 

* Bandwidth Reduction - NDI.Cloud uses high quality interframe compression to reduce the bandwidth per HD stream to as low as 2MBit/sec, whilst supporting up to 20MBit/sec for perceptually lossless compression. You select the maximum stream bandwidth for each site.

 

* UDP Protocol - NDI.Cloud moves your video over a UDP protocol transport for the long haul, necessary when dealing with large latencies between remote sites, which massively affects TCP bandwidth.

 

Sites connected with NDI.Cloud see all NDI sources on their wide area network as if they were local, and can selection them in the same way, with nothing extra setup to instantly begin accessing a remote NDI source.
