DVB-S/S2 TO DVB-T2 TRANSMODULATOR
1 INTRODUCTION
1.1
Description
The CompactMax is a compact transmodulation system that allows you to
distribute Satellite TV channels (DVB-S or DVB-S2) in Second Generation Digital
Terrestrial Television (DVB-T2) format.
The CompactMax has 4 satellite inputs and 4 DVB-T2 independent outputs. 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 extracts the sequence of digital data (Transport Stream) of
DVB-S/S2 signal. TS tables are regenerated (PAT, PMTs, SDT and NIT) and PID
remapped. Then signal is modulated again in DVB-T2 format, in order to
distribute it at frecuencies between 47 and 858 MHz with a resolution of 1 kHz.
After going through this process, there are 4 DVB-T2 independent signals that
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 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 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-T2.
•
Restoration of quality in a weak signal.
•
To move DVB-T2 channels from one frequency to other.
•
To change a programme grid without need to retune every TV on the
system.
•
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.
* only available for CompactMax-2
