Description
The KR3542D is a 1-U case which has 4 tuner inputs to receive signal from satellite,
These signals are multiplexed, descrambled and remodulated to 2 x DVBT carriers.
or 4 x QAM carriers as an option.
The KR3542D is also equipped with 2 ASI input, and output with 2 groups separate
ASI ports  and 2 MPTS UDP IP ports.
The output  DVBT modulated signals are to be received by TVs, STB etc..
QAM signals can be received by cable receivers.
The USB port is designed to record encoded video (TS) and save it in ts files in the
USB Keys or Hard Disks, and then the ts files can be playback through the USB port. 
The  four CAMs/CIs accompanied and BISS modules can descramble the programs input
from 4 Tuner inputs. Its pluggable structure design greatly facilitates the change of
modules (demodulator) as needed.
