[A-DX] DrTV - Fernsehen via DRM

["D. Name auf Wunsch gelöscht" <douglas.kaehler@xxxxxxxxxxx>]

Ich wage mal keinen Kommentar und verbreite schamlos nachfolgende Info, die
als apartes PDF in mein Postfach flatterte.

IBC was also the venue for the spectacular
?world-first? transmission of ?DrTV?, a new
application based on DRM (Digital Radio
Mondiale).
DrTV enables small-scale video services for
cost efficient large-area distribution of education
and information programs, whereby a
small-scale video signal is accompanied by
one or more audio streams.
DrTV represents a joint effort between
Thomson, Fraunhofer IIS and New Star
Electronics.
DrTV was carefully designed to provide
the most efficient transport encoding and
packetization while at the same time allowing 
receivers to robustly decode and quickly resynchronize
to the transmitted content. The system also 
features all benefits of the DRM
platform, like service selection by Unicode compatible
labels, alternative frequency signaling
and switching, announcement and warning/alert
features, etc.
DrTV can be transmitted over all broadcast
bands supported by the worldwide DRM standard,
including LW, MW, SW and above, and is
an ideal platform to reach audiences scattered
over a wide geographical area with a single
transmitter.
DRM transmissions over shortwave have
practically unlimited coverage possibilities
ranging from 100 square kilometers up to well
over 5?000?000 square kilometers depending
on transmission system. Thus DrTV can keep
citizens living abroad informed and up-to-date
about what is going on in the home country.
The DrTV application offers free-of-charge
reception and is independent of gatekeepers
and third-party providers like satellites and cable
networks.
DrTV is one example of the substantial advantages
made possible by digital AM Radio
Systems. Testing of the application on Thomson
transmission systems has begun.
