The Tangram is a compact headend processor and bridge between transmission formats. The chassis includes an integrated GigE switch and allows up to 6 individual modules in a single rack unit that can be combined to optimize your professional video headend.


This is Con from Inca. I’m going to tell you about the highly versatile WISI Tangram platform – specifically designed for high-density headend video processing in gateway and edge applications.

The Tangram allows operators to save rack space, power, and cooling costs by consolidating multiple functions into a single integrated solution, combining a 1RU base chassis with up to six video processing modules.

Combine modules to meet your application requirements, including:

  • IP to Analog in the GT21
  • IP to QAM, in the GT 23
  • Encryption and bulk decryption, in the GT 41 for Samsung LYNK, Pro: Idiom or Verimatrix
  • 8VSB/QAM to IP, in the GT33
  • ASI to IP and IP to ASI, in the GT 32
  • and Satellite reception, in the GT 31

Optimize your headend and maximize uptime by replacing legacy end-of-life or end-of-support equipment with a reliable, sophisticated solution.

Carrier-grade features include:

  • Support for MPEG-2 and MPEG-4, HEVC, SPTS and  MPTS, demux and remux
  • Flexible AC or DC power options with low power consumption
  • Bandwidth expansion with four SFP slots
  • Hot-swappable modules and power supplies
