Outline
XLD3304B is a cost-effective DVB-T Transmodulator developed according to DVB-T (EN300744) standard. It supports 2 Tuner input selecting from 4 Tuner ports. After demodulating, re-multiplexing, then it gives 1 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.
