DVB-S/S2 TO DVB-T TRANSMODULATOR
CompactMax-1

INTRODUCTION
1.1
Description
The
CompactMax-1
is a compact transmodulation system that allows you to
distribute Satellite TV channels (DVB-S or DVB-S2) in Digital Terrestrial
Television (DVB-T) format.
The
CompactMax-1
has 4 satellite inputs. Two inputs are for free channels and
the other two inputs for encrypted channels. There are also two slots to insert a
Card Access Module (CAM) to decrypt these channels and one input for RF
loopthrough.
The
CompactMax-1
extracts the sequence of digital data (Transport Stream) of
DVB-S/S2 signal. TS tables are regenerated (PAT, PMTs, SDT and NIT). Then
signal is modulated again in DVB-T format, in order to distribute it in RF. After
going through this process, the signal of the DVB-T module can be inserted into a
television distribution network. The output signal has high quality, allowing its
way through multiple amplifier stages, drifters, long cables, etc.
The
CompactMax-1
is managed through a webserver via remote control (LAN or
internet) and it is compatible with any standard browser. The webserver is easy
to use and has multiple setting options.
The
CompactMax-1
is integrated into a 19” (1U high) rack-mount case, which
fits in any TV head-end installation. It can also be mounted directly on the wall.
Among the practical applications of this transmodulator are:
•
Filter services in order to choose what DVB-S/S2 channels will become
DVB-T.
•
Restoration of quality in a weak signal.
•
To move DVB-T channels from one frequency to other.
•
To avoid degradation of signal.
•
To avoid overlapping on other channels.
•
To distribute encrypted programmes as free view in an internal TV
network.
•
To use as a TV repeater to cover shadow areas.
