1 GENERAL
1.1 Description
The EN-106 is a module able to generate a signal in DVB-T format
(Digital Terrestrial Television) from an audio / video (A/V) analogue input.
The audio / video analogue input has three RCA sockets, one for
VIDEO signal and two more for RIGHT and LEFT audio signal.
These two analogue signals are processed through a MPEG-2
compression system, that digitises and compresses them, obtaining then a
MPEG-2 transport stream, which is digitally modulated in order to obtain a
multiplex, with a television service, at the DVB-T output socket.
This DVB-T signal can be inserted via the RF input (for loop-through)
into an already existing television distribution network, with the advantages
of robustness and high quality that digital technology offers.
The EN-106 module adjusts the compression rate to the available
bandwidth, using the modulation DVB-T parameters.
