GQ-3680Q Multifunctional DVB-C Modulator

Q-3680Q is a new generation of multi-function modular IPQAM modulator from Gauss Bell. It can receive MPEG / II transport stream encapsulated by UDP / RTP with multiple IP input, and multiplex, scramble and insert local information. , And then perform QAM modulation, and finally output the RF signal.

GQ-3680Q can be applied to the front-end of cable digital television stations, sub-front-end computer rooms, or editing and broadcasting centers. A single device can meet the diverse information processing needs of customers; it can also be used as an edge IPQAM modulator under the VOD system architecture.
