DVB-С 8-ASI Scrambler
Brève description
DVB-С 8-ASI Scrambler is professional solution for multichannel digital video broadcasting: it is broadcasting server with own memory and integrated multiplexer, scrambler and modulator (up to 4 carriers), all in one, powerful conditional access system
DVB-С 8-ASI Scrambler forms a group output RF stream including up to 4 carriers. Each carrier can include its own program packet.
The DVB-С 8-ASI Scrambler can work in the following modes: 1RF, 2RF or 4RF. Up to 4 frequencies of RF output can be set in the range of 36-850 MHz.
DVB-С 8-ASI Scrambler is the hardware broadcasting server (able to work with subscribers’ data-base while the PC is off), it includes as well as TS remultiplexer (it has 8 ASI inputs) and QAM modulator (QAM 32/64/128/256, symbol-rate 1-6.9 Msymb/s).
DVB-С 8-ASI Scrambler has been designed for using in cable TV network. It is easy in operation and cost effective system.
Thus, with the help of our DVB-С 8-ASI Scrambler (in which are integrated four remultiplexers, four scramblers and four DVB-C modulators) you are able to organize CATV network for broadcasting up to 30 programs including PC channels monitoring system.
