Outline

JXDH-6405T-4A is a high performance and cost-effective DVB-T modulator designed by Dexin. It has 8 tuner inputs. After multiplexing and modulating process, it gives 4 DVB-T non-adjacent carriers output through one RF port. To meet customers’ various requirements, this device is also equipped with data port for 128 IP input and 4 MPTS output over UDP and RTP. Its pluggable structure design greatly facilitates the change of modules as needed. Moreover, the four CAMs/CIs accompanied and BISS modules can descramble the input programs from 8 Tuners and IP.

JXDH-6405T-4A can be upgraded and controlled through network system, which allows it widely used in digital broadcasting network and provide good signals for scientific laboratory and DVB-T STB.

Features

 *  4 Tuner (DVB-C/T/(T)/S/S2/S2X/ISDBT optional) + 4 Tuner with CAM (DVB-C/T/(T)/S/S2/S2X/ATSC/ISDBT optional)

 *  Demodulation Module (4*RF/Loop out + 4*CAM + 4*Smartcard)

 *  One CAM can decrypt multiple programs from Tuners and IP

 *  Maximum 128 IP input (MPTS/SPTS) over UDP and RTP protocol

 *  4 groups multiplexing +4 groups DVB-T modulating

 *  4 IP (MPTS) output over UDP and RTP protocol

 *  Support BISS descrambling

 *  Support accurate PCR adjusting, PID Remapping, PSI/SI rebuilding and editing, A/V PID filtering

 *  Web-based NMS management
