Instant connectivity

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.

Configurable latency

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 ).

Advanced error correction

The newest versions of Video Transport include our implementation of the Reed-Solomon Forward Error Correction (FEC) algorithm.

GPU-powered H.264 and H.265 encoding

Video Transport supports high-quality video encoding by Nvidia (learn more about ).

Browser support

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.

Contribution from partners

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.

Alpha channel support

Video Transport natively supports NDI video with alpha channel transparency data – you can transport both video and graphics (fill & key) in a single stream.

Multi-channel audio

Remote PTZ camera control

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®.
