1.1 Functionality
LAVISION-868FTA is a new generation ofRF-to-IP adapter, which can receive and demodulate eight
channels of DVB-S/S2,DVB-C and ISDB RF input signals, 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:
