Work starts on next-gen terrestrial spec

The Digital Video Broadcast Project has launched a "study mission" on
the next-generation terrestrial digital TV standard, dubbed DVB-T2,
Ulrich Reimers, chairman of the DVB Technical Module, said last week at
the DVB World forum in Dublin, Ireland.
Meanwhile, the DVB group is close to completing a study mission on
"satellite services to portable devices" (SSP), Reimers said.
The first meeting on DVB-T2 was held last week. In updating DVB-T, a
10-year-old terrestrial-broadcast standard widely used in Europe and
elsewhere, the group will seek ways to deliver higher data rates while
adding robustness and flexibility to the transport network.
Different parties, however, seem to have different visions for DVB-T2.
Suggestions include enabling digital TV delivery to power-hungry mobile
devices or on moving vehicles such as subways, trains and buses. Others
hope to see DVB-T2 evolve as a vehicle to deliver terrestrial
high-definition TV to spectra that will become vacant after all analog
TV broadcasting comes to an end.
Theo Peek, chairman of the DVB Project, said the DVB-T2 study mission
will likely conclude this fall. The results first must go to the DVB
Steering Board for approval. From there, the recommendations would be
handed over to the DVB Commercial Module for development of the
commercial requirements. Next, the DVB Technical Module would sort out
the tech requirements.
In contrast, the group's discussion on SSP appears much more
straightforward. "Just as terrestrial broadcasters have a DVB-H standard
for delivering digital TV to mobile handsets, satellite operators want
their own standard to address the portable market," said Reimers.
Could SSP end up competing against DVB-H?
Reimers called SSP a complement to DVB-H rather than a rival. "This
could be an answer to the unresolved issue of DVB-H," he said, referring
to the potentially prohibitive cost to network operators of expanding
the platform's coverage range beyond urban areas.
Satellite operators, meanwhile, might tap DVB-H to build a virtual
network of terrestrial repeaters, said Reimers. South Korea's
satellite-based Digital Mobile Broadcast network, for example, is
looking to add to its repeater network for its terrestrial TV service.
