NewTek Completes the IP Circle with NDI version 3 and Connect Spark

NewTek releases version 3 of its NDI, which includes the ability to multicast with no additional bandwidth requirement.

NewTek introduced its NDI (Network Device Interface) technology as a royalty free protocol at IBC back on September 8, 2015. For two years, the company offered customers and vendors a solution to using compressed IP signals as a transition path from SDI-based live and post production to IP infrastructures.

The company's NDI SDK (Software Development Kit) has been downloaded by more than 2500 companies and 10 million products have been NDI enabled according to company officials. 

Now NewTek has announced NDI version 3, and Michael Kornet, the company's EVP and GM shared some of the product's key features with The Broadcast Bridge.

“One of the biggest new features of NDI version 3 is its ability to multicast with no additional bandwidth requirement,” Kornet began. “You can now stream to a whole number of users with one stream, or unicast if you want. The only limitation is the network infrastructure.”

NDI version 3 also boasts a High Efficiency Mode called NDI|HX. This mode is suitable for wireless or long distance transmission, and includes embedded NDI support for such gear such as cameras and A/V signal converters.

“That way even those devices that don’t usually have NDI capability can take advantage of IP connectivity,” Kornet said.

NewTek is also introducing Connect Spark, a portable converter that can deliver SDI or HDMI signals wirelessly via WiFi or over standard Ethernet cable. The converters come in two flavors: HDMI-to-NDI and SDI-to-NDI.

Both versions provide 3G SDI or HDMI conversion up to 1080p 60 with loop through. As well as converting video to IP, each provides tally and can remotely record MP4 to an SD card or USB drive, with the recording controlled through a Web interface.

Because NDI version 3 includes PTZ (Point, Tilt, Zoom) camera control, that gives rise to a third new announcement: the world’s first PTZ camera with built-in NDI.

“From anywhere on your local area network, you just plug the camera into your Ethernet and the camera will be automatically detected and named,” Kornet said. “The power comes over the same cable as the tally, audio and video.”

The compressed signal inherent to NDI offers low latency and works over standard Gigabit Ethernet.

As reported in the article "NewTek has Gateway to SMPTE ST 2110," NewTek is also offering their Connect Pro product line as a gateway to help facilities get from compressed IP to the much larger 10 Gigabit bandwidth requirement for uncompressed IP and SMPTE 2110.

“Now people can have a complete end-to-end IP production system,” Kornet concluded. “The rate of adoption of NDI has far exceeded our wildest expectations, and these announcements put in the final pieces of the puzzle.”
