Mobile Viewpoint

The TerraLink-xCM encoder is a 19 inch high system with two bonded Ethernet connections and up to 8 x 3G/4G modems. It is the ideal back up solution for SNG trucks, but also enables any video vehicle with a bonded wireless uplink. The system supports both DHCP and fixed IP number configuration and has a separate LCD touch screen for management and configuration. The system can also be managed via the web using the LinkMatrix portal panel and makes it possible to configure maximum bitrate, video resolution and delay. The TerraLink-xCM is available with 1, 2 or 4 SDI inputs.

The TerraLink-xCM encodes video at H.265/HEVC and bonds 8 combined 3G/4G connections for high quality live streaming using Mobile Viewpoint award winning bonding technology. It is also possible to add WiFi and Ethernet connections to maximize the upload capacity.


We offer encoders in 3 different models:

  • TerraLink-1CM: Encodes 1 source, single HD/SD-SDI input, up to 8 modems 
  • TerraLink-2CM: Encodes 2 sources, 2 HD/SD-SDI output simultaneously, up to 8 modems
  • TerraLink-4CM:  Encodes 4 sources, 4 HD/SD-SDI output simultaneously, up to 8 modems


Usage Scenarios

  • Live uplink from vehicle or location using bonded Internet, 3G/4G and/or satellite links like BGAN and KA band
  • Back up solution for SNG trucks
  • Live radio report via the public internet (ISDN not needed any more)


Fixed Delay

The delay can be set from 0.8 sec up to 60 seconds  When the delay is selected this will remain the end-to-end delay during the complete broadcast. This is what we consider fixed delay time. IFB or return audio is also available at less than a second delay.


Store & Forward

The Terralink-xCM utilizes its bundling technology to become a high volume data Store & Forward unit and data bonding unit for Internet access. This means that the system uses its entire available bandwidth to transport any kind of file through its connections to a FTP server.


Hotspot and data bonding 

Like most WMT systems also a hotspot is available for Internet access. The hotspot uses the bonded bandwidth of all modems together providing enormous upload speeds. The device also supports full databonding across all connections and is available via the WiFi hotspot or via the Ethernet connection. Both the hotspot and databonding funtionality work in parallel with the transmission of video, however video is always prioritized so no interruptions due to unexpected data transmissions.


Manage & Control

In combination with a web-based platform the LinkMatrix it is possible to control, manage and administer all WMT devices and connections. The LinkMatrix is multi-destination and makes it possible to publish the same feed on many platforms including Social Media and private CDN’s.
