Using our DVB-S/S2 8-ASI Scrambler (in which are integrated remultiplexer, scrambler and DVB-S/S2 modulator) you are able to organize digital CATV broadcasting network including PC channels monitoring system.


  • DVB-S/S2 8-ASI Scrambler has integrated re-multiplexer with 8 ASI inputs — which allows you to form program packages from 8 independent transport streams for further broadcasting
  • Supports both SD (Standard Definition) and HD (High Definition, 1920x1080i) channels, H.264 / H.265 standard
  • Typical DVB-S/S2 set-top-boxes can be used as subscribers’ receivers
  • 90% of STBs support the working with DVB-S/S2 8-ASI Scrambler
  • Connection to PC for management: Ethernet (100 Mbit /s), RJ45
  • 1Gbit data port for 5 IP outputs (UDP/RTP protocol)


  • Works 24/7/365
  • Supports state-of-art broadcasting standards
  • Automatic and manual PID insertion
  • EPG, OTA, LCN support, Network search
  • Generation of output stream with up to 92 PID selected from 8 ASI inputs
  • Optional enabling/disabling of stuffing in the IP output
  • Supports QPSK, 8PSK and (as option) 16APSK constellation types
  • The ability to set the frequency of the output IF signal in the range of 100-2400 MHz
  • All settings, including DVB-S/S2-mode switching and upgrading, are carried out via LAN (Ethernet 100)
  • 5 IP outputs can be used for IP streaming by UPD/RTP protocol, as well as for output or input TS monitoring at your PC
  • Parameters indication on the LCD
  • Quick replacement of the device in the system without stream rescan
