IDH2-3000 Series is a new generation of Multifunctional Modular IP Multiplexer-Scrambler-QAM
modulator, which can receive TS from the three 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 module management opens the scrambling function and configures the numbers of output
modulation channel through software authorization, as shown in the table below:
