Abstract :
Utilising the DVB-T specification fully will allow broadcasters choose from different modulation formats including QPSK for transmission of MPEG-2 signals over difficult media. Very rugged signals with excellent power and echo performance can be selected with DVB-T modems for contribution circuits. This paper details preliminary results of the transmission of a 6 Mbit/sec MPEG-2 signal from a mobile vehicle to a main station on an upper adjacent channel to existing PAL I broadcasts. It shows that it is possible to use DVB-T signals for contributions from mobile transmitters without signal degradation
