DVB Plans to Complete 3DTV Spec by November
AMSTERDAM: Europe’s digital broadcasting standards body
said it would complete a 3DTV specification by November, according to press
reports. The DVB said it would likely follow approval of the commercial requirements
for a frame-compatible 3DTV system, Broadband
TV News said. A sub-group within the DVB is defining those requirements
now, said its chairman David Wood.
“We believe the die has been cast on ordered and standardized broadcast and
cablecast 3DTV for the frame-compatible community,” said Wood said at a press
conference at IBC in Amsterdam.
This summer’s 2010 World Cup 3D video was delivered in the frame-compatible
format, in which two distinct left- and -right-eye images are captured, encoded
and transmitted by TV providers. Members of the European Broadcasting Union,
who use the DVB transmission standards, have indicated a preference for a
service-compatible 3DTV system.
The service-compatible format is currently used by European broadcasters to
deliver HDTV (via the DVB-T2 standard), and would require additional data for
creating 3D images on 3DTV sets. The frame-compatible system, while it would
work on the existing HDTV architecture, requires more bandwidth than the
service-compatible format. More than half of European broadcasters polled by
the EBU said they’d prefer the service-compatible format.
The DVB’s Dr. Peter Siebert told
News that a service-compatible 3DTV spec would be completed by this
time next year.

“Each eye’s picture appears on the 3D TV screen, one after the other. Images
are sent to the eyes at a rate of around 50-60 images per second, making the
process imperceptible to the viewer.”
