Delegates at this week's EBU FORECAST'12 seminar heard plenty of
evidence pointing to the dilemma facing broadcasters today: while the
are increasing pressures to deliver more content and more services, the
essential real-estate that drives broadcasting - spectrum - is
continually being squeezed by the demands of the mobile sector.
Live TV audiences are growing and there is an ever increasing demand
for higher quality as sets get bigger. FORECAST'12 attendees heard about
the techniques broadcasters are exploring to help them meet these
demands through more efficient spectrum use. Mobile industry people were
also in attendance to present their efforts to develop networks that
would cooperate more effectively, but the demands from that industry for
bigger slices of the spectrum currently used for broadcasting are plain
to see.
On day two of FORECAST'12, Prof. Reimers of TUBS spoke about his
dynamic broadcasting and LTE overlay projects: both designed to merge
the key assets of mobile, broadcast and fixed broadband networks. His
message was to point towards the network architectures, rather than
operating in the silos that are mobile telecommunications and
broadcasting. Some delegates voiced concern that the necessary
cooperation between the two sectors would not happen.
A key prsentation on day two looked at the environmental impact of
broadcasting. Simon Tuff (BBC) pointed to the fact that 60% of the TV
industry's impact is due to domestic installations (TV sets, antenna
amplifiers, etc.). He cautioned that proposals to move broadcasting to
low-tower, low-power topologies could increase the energy consumption of
a typical network by 100%. He highlighted the EBU's programme on Green
Broadcasting as an important first step towards finding realistic ways
to address these issues.
FORECAST'12 attracted more than 110 participants and speakers drawn
from public and private broadcasters, network operators, regulators,
academia and the telecoms industry. The presentations from the event are
available to EBU Members from the event webpage.
