Thanks to a network of handshake servers and a built-in NAT traversal feature, all nodes available within a Publisher ID are discovered automatically. In most conditions, no is required to transmit live video between locations.
In addition to being really low, transmission latency can be configured and even fixed:
Real-time latency. In good conditions the technology is capable of bringing latency down to 50-150 msec, which makes the technology applicable for video conferencing. To be used when latency is more important than video quality (network issues can lead to frame drops).
Predictable reliability. If quality is important, a higher latency setting can be used. More latency gives our protocol time for error correction (to resend the missing frames and restore the image).
Fixed latency. The latency buffer can be fixed to a specific value, which makes it possible for several sources to arrive at the same time (key for ).
The newest versions of Video Transport include our implementation of the Reed-Solomon Forward Error Correction (FEC) algorithm.
Video Transport supports high-quality video encoding by Nvidia (learn more about ).
It is possible to contribute to a production or view any of the streams via a browser on almost any device (such as when you want to add spontaneous remote guests to a live show). Learn more about and page.
When collaborating with someone who shouldn't have access to all the feeds available under your Publisher ID, use the Partner License to share a specific feed.
Video Transport natively supports NDI video with alpha channel transparency data – you can transport both video and graphics (fill & key) in a single stream.
When providing return feeds to speakers, it's often convenient to embed multiple audio feeds and allow the speaker to choose just the right audio feed for him (learn more in our guide for ). Video Transport supports up to 16 audio channels within a single feed.
With Video Transport you can (provided via VT's two-way data channel with NDI metadata support). Remote control is currently supported only for cameras with NDI®.
