QUICK CONFIGURATION GUIDE
1 INTRODUCTION
The DT-504B is a module able to generate a single transport stream
in COFDM format from several audio / video (A/V) analogue signals.
It has 4 Audio / Video analogue inputs. Each A/V input has three
RCA connectors, one for video signal (VIDEO) and two more for audio (right
and left audio).
Each A/V input is coded by means of the MPEG-2 compression
system. Then the resulting signals are processed by a multiplexer that
brings together all in one TS. This TS is serialized into DVB-ASI format and
modulated in a DVB-T output signal.
Subsequently, the DVB-T output signal can be inserted into a
television network with the advantages of robustness and high quality that
digital technologies offers.
At the bottom, the screen shows the Transport Stream (TS) Status,
the bitrate used in kilobit per second and the percentage of bitrate used
relative to total available.
The DT-504B module adjusts the compression rate to the total
bitrate available, using the modulation parameters.
