VT Guest Link

A quick guide on using the VT Guest Link for outside contribution via a web browser.

The Guest Link is an easy-to-use web-based contribution link that runs on almost any device (need compatibility chart here) and provides bi-directional connectivity between the contributor (speaker) and the receiving location (studio).

We recommend using Google Chrome for optimal performance.

Using the Guest Link

The Guest Link requires to use VT Publisher and VT Receiver (it currently does not work with VT Server and cannot be set up via the Control Panel).

First, you have to download our latest version (starting with 1.7.0.565). You can do it on our web site. After you download and extract the Video Transport:

  • Launch the VT Publisher application. Select the video source from the “studio”, which we will send to the remote guest. Hit “Start Publishing”.

  • Using the context menu of the selected channel from the studio, select “Copy Web Guest URL”:

  • Insert the "Web Guest URL" into the browser:

  • The stream from the browser will appear in the VT Publisher instance as one of the published sources. This feed can be delivered to required number of VT Receivers.
