Overview
The DMB-9020C HD Professional IRD integrates broadcast level Receiver, Demodulator, Descrambler and Decoder. The Rich variety of INPUTS models options enables it to meet the diversified broadcast applications and distribution applications, supporting the sources from satellite (DVB-S/S2), terrestrial (DVB-T), Cable network (DVB-C). Moreover, the DMB-9020C adopts the state-of-the-art decompression technology, capable of decoding Multiple Format Transport Stream(TS) with ultra-low latency which involves HD and SD,MPEG-4 AVC/H.264 and MPEG-2, decoding and output the Composite video,Component(YPbPr),HDMI signal and two Audio signals(2 Audio PID) which can be selected by NMS based on the actual needs. Meanwhile, the security of content is all important, the HD Professional IRD supports all major Condition Access Systems including BISS 1,BISS E ,Irtedo, Viaccess and Conax etc. with 2 DVB-CI slots(Common Interface). All of above features simplify the digital TV headend system and distribution system, enhancing the stability of broadcast system, saving the cost and space for broadcasters, digital TV operators, video service providers.
