Product Usage Instructions

The Dibsys Technologies IRD1311 has multiple applications:

Video contribution and distribution in TV studio stations
Satellite digital TV, terrestrial digital TV, and cable TV broadcasting
Contribution decode of high bitrate H.264 video service

IRD1311 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, IRD1311 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.
