Introduction 

DE200 multi-function decoder is new generation decoder based onMPEG-2/DVB standard, which is developed by Beijing CircLoop DigitalImage Tech. Co., Ltd independently. With various standard input andoutput, it can provide great compatibility solution forprofessional broadcasting company. This equipment combines thetransparent transmission of DVB common interface, so it completelycan meet the requirement of CATB head-endproducts. 

with two channels built-in decoding module in the equipment, itcan decode two channel program simultaneously.

Abundant input are available: IP input,two channels independentASI input,E1* N input (N=1,2,3,4),DS3/E3 input,GPS clock input(10Mz, 1pps), DVB-C RF input,DVB-S RF input ,as well it has ASI,DS3/E3 loop-output.

Abundant video and audio output are available: support 2channels analog video and audio output (each one includes main andstand by output) ,2 channels SDI embedded audio output (each oneincludes main and stand by output) , 2 channels AES/EBU audiooutput

It supports various interface converting: supports DS3/E3 toASI,E1*N to ASI,IP to ASI, DVB-C/S-ASI converting, supports DS3/E3to IP,ASI to IP,E1*N to IP,DVB-C/S to IPconverting,.
