8/16/24/32 Frequency Multi functional IP-QAM Modulator

Model No:GQ-3670

1: Support 8/16/24/32 frequency Channel scramling and modulation

2: Support up to 4 cas encryption

3: Viarous case optional

Product Overview

      Multi functional IP QAM modulator GQ-3670 can receive multiple MPEG-2 TS in form of IP data, and then multiplex, scramble, and insert local information to the TS. It finally outputs RF signals after QAM modulation. The input signal could be the IP output from encoder / receiver / multiplexer / VOD server, and it can be used in DTV core to edge TS processing and modulation.

.
