DHP230 DTV Headend Processor

Outline

DHP230 is a high-performance and cost-effective DTV Headend Processor designed by Dexin. It support max 3 modules inputs(demodulating/descrambling module at present), after multiplexing and modulating process, then it gives 16 DVB-C or 8 DVB-T or 8 ATSC or 6 ISDB-T non-adjacent carriers output within 192MHz bandwidth. To meet customers’ various requirements, this device is also equipped with 128 IP inputs over UDP and RTP, 1 USB input, 1 ASI input and 1 DVB-S/S2/S2X input and 1 ASI out and 16/8/8/6 MPTS outputs over UDP and RTP/RTSP. Its pluggable structure design greatly facilitates the change of modules as needed. Moreover, the CAMs/CIs accompanied and BISS modules can descramble the programs input from Tuner inputs.

DHP230 can be upgraded and controlled through network system, which allows it to be widely used in setting up digital broadcasting network and very adaptable to newly generation CATV broadcasting system.
