Your signals are remote. Your workflow does not have to be.

Sending a live feed over the Internet shouldn't force the control room to use consumer calling apps, give up SDI and NDI, or build a custom transport stack for every production.

Extend the signal path, not the production footprint

Send contribution feeds to the control room while keeping switching, graphics, audio and monitoring at the production hub.

Use the interfaces already in the rack

Take in SDI, HDMI, NDI, cameras, audio devices and supported network streams. Deliver the received feed as NDI, SDI, audio or a virtual output.

Choose the right latency for the job

Run close to real time, add recovery time when reliability matters, or use a fixed buffer when multiple feeds need to arrive together.

Operate from anywhere

Publish, route, monitor and configure distributed VT nodes from the Control Panel or through the VT API.

One transport layer.
Every side of the production.

  1. 1

    Publish

    Capture an SDI, NDI, camera, audio or supported network source.

  2. 2

    Connect

    Attempt a direct peer-to-peer path; use a gateway when a direct connection is unavailable.

  3. 3

    Receive

    Decode the feed, apply the required buffer and make it available to the local workflow.

  4. 4

    Control

    Route, preview and monitor distributed locations from the Control Panel.

From one return feed to a distributed production

REMI and multi-camera production

Move camera feeds from a venue to a central control room and use fixed buffers for predictable arrival timing.

Path

Venue cameras → Publisher → WAN → Receiver outputs → production switcher

Remote contribution

Bring anchors, commentators and interview guests into a native SDI or NDI production.

Path

Guest camera + mic ↔ studio return → SDI/NDI production

See how Church of the Assumption of the Blessed Virgin Mary uses this

Program return and confidence monitoring

Control the trade-off between speed, quality and resilience

Configurable latency

Choose real-time, ultra-low, low, reliable or fixed buffering at the receiver.

Error recovery

Use retransmission and Forward Error Correction to protect the feed against packet loss.

GPU-accelerated codecs

Use H.264, HEVC and AV1 on supported NVIDIA hardware, plus CPU H.264, Quick Sync options and VP9.

Production formats

Transport HD and UHD video with configurable bitrates up to 50 Mbps.

Multi-channel audio

Carry up to 16 audio channels with masks, external audio, ASIO splitting and contributor mixes.

Metadata and control

Carry supported NDI metadata, VANC closed captions and timecode.

Real-time / Ultra-low

~50–150 ms IN OUT

Minimal buffering. Prioritizes immediacy over recovery.

Low / Balanced

~150–400 ms IN OUT

Moderate buffering. Some recovery headroom for typical networks.

Reliable

~400–1200 ms IN OUT

Large buffer. Maximum time to retransmit and recover lost packets.

Lower latency prioritizes immediacy; a larger buffer gives the transport more time for recovery. Values are illustrative.

Operating goal Suggested mode Typical use
Minimum delay Real-time / Ultra-low Interview, interactivity, return feed
Balanced operation Low General contribution
Maximum recovery Reliable Unstable or long-distance network
Predictable arrival Fixed buffer Multi-camera REMI

Direct when possible. Routed when necessary.

Video Transport handles connection establishment separately from the media path, so teams can deploy quickly and retain routing control in restricted environments.

Bring remote contributors into the same signal chain

Send a secure contribution link or deploy VT Guest when the production needs a reliable transport protocol, GPU encoding, and a controlled contribution kit.

Automatic per-guest mix-minus can create individual return mixes for up to eight Web Guests.

All native applications are delivered in one portable Windows package. No installer is required.

On-premises Video Transport

Own the transport layer when the workflow demands it

Deploy signaling, TURN, VT Gateway and optional SFU services in your own data center, private network or cloud account.

  • Control media routes Define where traffic is allowed to travel and place gateway infrastructure close to production locations.
  • Build predictable operating costs Scale infrastructure around major events and reduce it when demand falls.
  • Improve resilience and route quality Place services in regions and facilities that make sense for contribution paths.
  • Deliver under your own brand Host Web Guest and Web Preview on your domain and apply a white-label interface.
  • Integrate with existing operations Connect Video Transport to a NOC, MCR, booking system or customer portal.
  • Control stream access Use individual accounts, activation windows, expiration times and connection limits.

Automation and integration

Build Video Transport into your own control plane

The Socket.IO-based VT API provides programmatic control of VT Publisher, VT Receiver and VT Server. It is designed for on-premises deployments and requires a dedicated API license.

  • Discover and monitor nodes Track Publisher and Receiver managers as locations join or leave a production room.
  • Create and control routes Enumerate sources and devices, start or stop channels and choose receiver outputs.
  • Read operational data Retrieve format, frame rate, codec, bitrate, connection state and JPEG preview frames.
  • Control remote contributors Read and update Web Guest camera, microphone, format, codec, bitrate and audio settings.

Engineering FAQ

What latency should we expect?

In a suitable network, real-time mode can operate around 50–150 ms. Actual latency depends on RTT, buffering, encoding, decoding and output processing.

Does every deployment require public inbound ports?

Not necessarily. Video Transport uses ICE and can fall back to VT Gateways or TURN. Restricted environments can define a specific UDP range or deploy on-premises.

Can we synchronize several remote camera feeds?

Receiver instances can use the same fixed buffer for predictable arrival timing.

Which codecs are available?

Desktop workflows support H.264, HEVC and recent NVIDIA AV1 implementations. Browser contribution uses WebRTC with H.264 or VP9.

Can it integrate with SDI and NDI at the same time?

Yes. Publisher and Receiver can bridge supported SDI/HDMI devices, NDI, cameras, audio devices and network streams.

Can we keep the infrastructure inside our network?

Yes. The on-premises edition supports customer-controlled signaling, TURN, VT Gateway and optional SFU infrastructure.

Is there an API?

Yes. The VT API controls managers, channels, properties, previews and Web Guest settings for on-premises deployments.

Does it run on macOS or Linux?

Publisher, Receiver, Guest and Server are Windows applications. Browser tools run on other supported platforms.
