Under the hood, NDI uses discrete cosine transform (DCT), the technology used in JPEG, to compress the video signals, which sounds a lot like Motion JPEG or AVC-Intra. vMix is so excited about the new technology that if you Google “vMix NDI YouTube,” you’ll see more than 20 videos the company offers, discussing the technology and vMix’s implementation. It’s no surprise that Telestream has incorporated NDI into Wirecast while StudioCoast did the same for vMix. Why would NewTek open up the spec? Basically, to promote IP-based video workflows, although the move benefits all producers of content creation products, as well as other live video mixers. Even those vendors making competitive products.” What we’ve done now is up all parts of this-the sending part is open, but now the receiving part is open. … We’ve been relatively open about giving anybody the ability to send us video. In an interview in TV Technology, NewTek president and CTO Andrew Cross stated, “For years, we’ve had the ability to take video from a Vizrt virtual set system, for example, and send it over IP into a NewTek TriCaster. Now, NewTek has simply opened up the spec for others to use without any charge. NewTek has used NDI for years to enable complementary products to send content streams to the TriCaster for input via a network input in TriCaster. Now, as long as the systems are connected on the same LAN, either system can send a stream to the other over the network. Previously, if you had two TriCaster systems in two different studios, you may have had to string an HD-SDI cable or fiber connection between them. NDI technology delivers extremely low-latency video streams over a local area network such as the 1Gbps Ethernet network in your office or studio. I’ll also look at the base capabilities of each system and explore when it’s time to consider third-party offerings.
I’ll explain what NDI is and how it works, and I’ll explore how it enhances the titling capabilities of the NewTek TriCaster, Telestream Wirecast, and vMix GO. If you haven’t been watching the live titling space, you’ve missed the revolution, and your productions may be falling behind in terms of graphics quality.īut don’t worry. While these systems may be too costly for many live event producers, the technology that powers the Lyric/TriCaster integration, called Network Device Interface (NDI), now enables similar workflows on less expensive systems.
“In fact, there are no other production elements that can enhance a video presentation as much as high-quality graphics.” To incorporate graphics and titles into the Eagles’ live productions, Leblang uses two ChyronHego LyricIP systems (formerly named ChyronIP) connected to two NewTek TriCaster 8000 mixers running Advanced Edition. “Titles and graphics are absolutely integral to providing a high-quality experience,” says Mark Leblang, studio/live production manager for the Philadelphia Eagles.
