Outline
NDS3304BT is a cost-effective DVB-C/T Transmodulator developed according to DVB-C and DVB-T standard. It supports 4 Tuners input. After demodulating, re-multiplexing, then it gives 4 DVB-C RF or 2 DVB-T RF out. BISS function is also embedded to descramble multiplexed programs. With the features of low cost and high performance, it provides various solutions for operators to re-distribute contents.
* Demodulating + re-multiplexing +BISS descrambling +modulating in one box
* Support 4 Tuners input (3*DVB-S/S2/S2X+1*DVB-S/S2/S2X or 1*DVB-C/T/T2/ISDB-T)
* Support BISS descrambling (up to 60Mbps)
* Support 4 DVB-C RF or 2 DVB-T RF out
* Support PID pass-through
* LCD / keyboard and web-based NMS operations and upgrade via web
