Representatives
from European mobile operators, TV broadcasters,
industry analyst firms and regulatory bodies
attending this demonstration were able to
enjoy high quality images displayed on SAGEM
myMobileTV handsets. These terminals are
using the S-band telecom frequency between
2.17GHz and 2.20GHz, which is adjacent to
the 3G/UMTS band. 30MHz of spectrum is currently
available all across Europe and in other
major regions in the world.
DVB-SH
is a new technology targetting the S-band.
DVB-SH is a related standard to DVB-H. With
DVB-SH technology, Mobile TV signals can
be broadcast from satellites as well as
from terrestrial transmitters directly to
handhelds. DVB-SH handhelds can be designed
in such a way that they become compatible
with DVB-H so that both standards can be
received in one end-user terminal.
In
addition, Alcatel demonstrated two possible
key technical features using the DVB-SH
standard. Reception Antenna Diversity, a
feature using two antennas inside the same
mobile device, enables improvements in the
signal quality under difficult conditions.
Furthermore, improved Time Interleaving
overcomes fading impairment in mobility
conditions. The significant quality enhancement
was demonstrated by implementing these DVB-SH
features.
