SCT2x4 PLUS
HITS Satellite to Cable Transcoder Module
PRODUCT DESCRIPTION
The SCT2x4 PLUS is a Satellite to Cable Transcoder system
designed for the HITS (Headend-in-the-Sky) satellite service.
Each SCT2x4 PLUS module contains two independently
controlled satellite tuners with input frequency ranges of
950-2150 MHz. This unit is specifically designed for 8PSK
transponders using DVB-S2 error correction. Due to the
high overall bitrate on HITS 8PSK transponders, all of the
programs contained within them cannot be accommodated
in a single QAM 256 channel. The SCT2x4 PLUS automatically
directs programs across two QAM channels based upon the
transponder selection. SAT 1’s programs are directed to QAM1
and QAM 2 while SAT 2’s programs are directed to QAM3 and
QAM 4. The four (4) output QAM channels can be grouped in
any 42 MHz contiguous bandwidth in the frequency range of
54-864 MHz.
The SCT2x4 PLUS does not alter the satellite encryption used on
the program streams. The encrypted streams pass intact through
the transcoder and are delivered to the QAM set top boxes
where the actual descrambling occurs. The SCT2x4 PLUS may
be monitored and controlled via GUI-based web pages from any
computer locally or via the internet.
FEATURES & BENEFITS
• Supports HITS 8PSK transponders with DVB-S2 FEC
• Equipped with an integrated automatic satellite switch that allows
operator to select inputs from 2 different satellites
• Supports ITU-T J.83B QAM 256 output
• Compact design allows for deployment of 4 transcoder modules (8
transponders/16 QAM), including the power & control module, in 3RU
• GUI-based menu, including SNMP-based management, provides
remote monitoring/control capabilities
