Outline
Xielide XLD3304 DVB-T modulator is a high performance modulator developed according to EN300744 standard. It provides a more powerful receiving ability to receive double IP streams from encoder, multiplexer, DVB gateway and etc. After multiplexing and DVB-T modulating, it output via two adjacent carriers.
For management and operation, this device supports local and remote control through a web-based NMS system.
