点击图片查看原图德芯大卡机，德芯大卡调制器NDS3348C is a high performance and cost-effective DVB-C modulator designed by Dexin. It has 8 tuner inputs, after multiplexing, scrambling and modulating process, then it gives 4 DVB-C non-adjacent carriers output. To meet customers’ various requirements, this device is also equipped with 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 programs input from 8 Tuner and IP input.
NDS3348C 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.
Features
* 4 Tuner (DVB-C/(T)/S/S2 optional) + 4 Tuner with CAM(DVB-C/(T)/S/S2/ATSC optional) input
* 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
