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.

It shows that it is possible to use DVB-T signals for contributions from mobile transmitters without signal degradation.
