Product Overview

多路解调适配器

GC-1815 is the latest professional IRD launched by GOSPELL, and was designed to demodulate the scrambled broadcast streams from satellite (or cable, terrestrial) network, IP network and local headend featured with DVB-ASI.

In order to cater for demands of interoperability of different operators broadcast services, GC-1815 is equipped with two 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 140Mbps of de-scrambling output bit rates for SD, HD and Full HD MPEG-2, MPEG-4 AVC, AVS and AVS+ broadcast services. It supports various decoding output interfaces, composite video, unbalanced stereo audio, HDMI and 3G-SDI outputs, It can be widely used for broadcast distribution and contribution.
