Overview:
This modulator is a new generation of Multifunctional Modular IP QAM modulator, which can receive TS from IP interfaces, and then multiplex, scramble and process it with channel coding. It adopts our newly developed functions such as “Module Management”, device scrambling, and channel modulation. The flexible customization and high expansibility can satisfy the user’s current and future DTV system requirements. The product is mainly applied to the DTV network head end room, edge of DTV backbone network, and DTV branch head end room.
