19 inch rack solution

The SL-25 encoder is a 19 inch 1U high system with two bonded Ethernet connections which can be extended with 8 times 3G/4G modems. The SL-25 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 Video Manager portal panel and makes it possible to configure maximum bitrate, video resolution and delay.

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)



The solution can be delivered point to point or via a backend server. The backend server is available in two flavors. The basic backend server can handle 2 SL-45 encoders and 2 playout systems and store up to 25 hours of D1 video (depending on the hardware version). The premium server can handle 20 SL-25 encoders and 20 playout systems and store up to 100 hours of D1 video (depending on the hardware version)

IP Management

  •  10/100/1000 base-t


  • Dedicated appliance 220 volt
  • Weighs approximately 2,5 kilograms
  • 1U 19” rackmount

Operations settings

  • Live: Adaptive encoding and bitrate change with three options or with a slider (optional), with configurable delay between 1*-60 seconds (* On software version 17.4)
  • Store and Forward: send over contents of an USB stick to a FTP server
  • Recording: CBR encoding at 30 Mbit on internal or external SSD disk
  • Satellite and Satellite + 3G: Specific modes to optimize transmission over BGAN and KA satellite. With Satellite +3G we can keep the delay at 1.8 seconds using 3G/4G modems for the return channel and IFB.
  • Disabled/Data bonding: In this mode the unit is a true data bonding unit for high speed uploads and Internet access. Also in the other modes data connectivity is available but live video gets prioritized.
  • PostPro license (optional): In this mode the system records next to a high res CBR a low res proxy file which can used for remote editing and only partial retrieve


  • PSU 90-220 Volt AC to 12 Volt DC
