4 Tuner DVB-S2 DVB-C ISDBT to 2 DVB-T 4 DVB-C Transmodulator

Outline

NDS3304B 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.
