PD4535 DVB-S2 Multi Decryption IRD


PD4535 IRD is Symbol’s new design which integrates demodulation DVB-S/S2 (DVB-C optional), de-scrambler and multiplexing in one box to convert RF signals into TS output. It is a 1RU box which supports 4 tuner inputs, 1 ASI input and IP input. The 4 CAMs/CIs accompanied can descramble the programs input from encrypted RF, ASI and IP. The CAM requires no unsightly external power cords, cables, or additional remote control device. To meet customers’ various requirements, PD4535 is also designed to de-mux programs from any input, and output TS over 48 SPTS & 4 MPTS UDP, RTP/RTSP.
