Product Overview

多路解调适配器

GC-1818 is a multi-channel, high performance professional receiver launched by GOSPELL, and was designed to demodulate and descramble up to four scrambled program streams from satellite (or cable, terrestrial) RF network and (or) Gigabit Ethernet network and local ASI.

In order to cater for demands of interoperability of different operators and ever-growing data rate of television services, GC-1818 is equipped with four DVB-CI complied Common Interfaces to meet the demands of descrambling for different scrambled programs using different DVB SimulCrypt CA(s), and supports up to 280Mbps of de-scrambling output bit rate for high definition and standard definition TV programs. Compared to conventional traditional single-channel or dual-channel professional IRD, GC-1818 can deliver double or better capacity of descrambling for operators in 1RU only.

GC-1818 supports Web browser and SNMP management for local and remote management and maintenance, which can significantly reduce management time and operating expense (OPEX) for operators. It enables operators to provide a wide range of highly costeffective, high performance and high-quality services to subscribers with lower total cost of ownership (TCO).
