Video conferencing

Canvus brings a video call from your video-conferencing (VC) system onto the wall. The call shows in a window that you can move and resize, and you control it by touch on the wall: join, mute, layouts and the cameras. Wall content goes the other way into the call. You can share one window, a group of windows or the whole wall.

Bonus: Microsoft Teams over NDI

No VC system? Run Teams on a computer on the same network and connect it to Canvus over NDI in both directions. No capture card or spare video output is needed. See Microsoft Teams over NDI.

How it works

How a video-conferencing (VC) system connects to a MultiTaction wall 1. The VC system's HDMI output goes into a capture card in the wall computer, so the call appears in a window on the wall. 2. A spare HDMI output of the wall computer goes into the VC system's content input, so wall content is shared into the call. 3. A Sander touch bridge plugs into the VC system's USB port as a touchscreen. 4. Sander receives the touches made on the call window from the wall computer over the network.

The VC system is the one you already use: a Microsoft Teams Rooms, Zoom Rooms, Neat, Logitech or Cisco system. It keeps its own camera, microphones and connection to the call. Canvus becomes its screen, and its touchscreen as well. You need no Tap, touch panel or separate screen.

  1. The call comes onto the wall. The VC system's main HDMI output, which would normally drive a screen in the room, goes into a capture card in the wall computer. The call is a live input in Canvus, in real time and at up to UHD resolution. It shows in a window that you can place anywhere on the canvas.
  2. The wall goes into the call. A spare HDMI output of the wall computer goes into the VC system's content input. Canvus sends to it what you choose: one window, an area of the canvas with several windows in it, or the whole wall.
  3. The wall is the VC system's touchscreen. A SANDER touch bridge plugs into the VC system's USB port. The VC system sees an ordinary USB touchscreen. No Tap or touch panel is needed.
  4. Touches go to the VC system. When you touch the call window, Canvus sends the touches to SANDER over the network, and SANDER passes them to the VC system. You use the VC system's own on-screen controls, at full size on the wall.

What you need

  • A VC system that accepts a USB touchscreen on its HDMI output. See Supported VC systems.
  • A wall computer running Canvus, with an HDMI capture card supported by Canvus and a spare HDMI output on its graphics card. See Video inputs and Video outputs.
  • A SANDER touch bridge. It uses the network the wall's displays already use to send touch to the wall computer, over Wi-Fi or an Ethernet cable. SANDER has both. The cable can also go straight to the wall computer.
  • Two HDMI cables, rated for UHD when you want UHD.
  • Optionally, SiteManager to write the display layout and the video output for you.

Set it up

Work through these pages in order. Each one is a single step.

  1. Supported VC systems: check that your VC system supports a USB touchscreen.
  2. Connect the hardware: the two HDMI cables and SANDER.
  3. Add the output to the display layout: screen.xml, with SiteManager or by hand.
  4. Define the video output: the [output:<name>] section in mt-canvus.ini.
  5. Set up touch control: connect SANDER to the call window.
  6. Run a call: place the call window and share content into the call.
