Overview

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. Specifications: maximum 128 IP input(MPTS/SPTS) over UDP and RTP protocol from DATA 1 port; 1 USB Player input for re-mux (“xxx.ts” video); 16 non-adjacent carriers output (maximum bandwidth 192MHz); 8 non-adjacent carriers output (maximum bandwidth 192MHz); 8 non-adjacent carriers output (maximum bandwidth 192MHz); 6 non-adjacent carriers output (maximum bandwidth 192MHz); Input Frequency: 950-2150MHz; Input Frequency: 950-2150MHz
