ClearView KR3542D Multi-input DVBS2 to DVBT Transmodulator


KR3542D multi-input modulator is ClearView’s all-in-one device which integrates demodulation, trans-mux and
modulation in one case to convert DVBS2 signals into DVBTsignalst


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.

Supports 4 DVB-S2 Tuners and 2 ASI input ports
Accurate PCR adjusting
PSI/SI editing and inserting
PID Remapping
Excellent RF output performance index, MER>40db
2 x DVB-T RF out or 4 x DVB-C out. (This needs to be specified when ordering)
2 separate ASI&IP (2 x  MPTS over UDP) mirror 2 RF output
4 CAMs can decrypt multiple programs from the 4 Tuner inputs
Supports BISS descrambling
Record encoded TS and playback TS files (*.ts) through USB port
LCD display and keyboard
Web management, Updates via web and USB
