EU Broadcasters Prefer Service Compatible 3DTV
LONDON: A majority of broadcasters in European Union
countries prefer a 3D format other than the side-by-side stereoscopy currently
used by most operations. More than half would prefer to see a service-compatible
format adopted, according to a European Broadcasting Union survey picked up by Broadband TV News. EBU polled mostly
public broadcasters regarding which 3DTV system they would prefer.
The service-compatible system is now used by EU broadcasters to deliver
over-the-air HDTV signals. Transmitting additional data provides the
information necessary to create 3D images on 3D-decoding TV
sets. The side-by-side 3D currently in wide use is a frame-compatible system by which
dual images are transmitted. The images appear side-by-side on a 3DTV display
and require synched shutter glasses for viewing.
Less bandwidth would be required for 3DTV using a service-compatible
versus a frame-compatible format. Around 52 percent of the EBU broadcasters
polled preferred standardizing a service-compatible system. Just over 11
percent were said to favor frame-compatible 3D, while 26 percent said none of
the current 3DTV systems were adequate.
Broadband TV News,
Cambridge, England, reported last month that service-compatible 3DTV tests were
being conducted by infrastructure specialist Arquiva in the lab. An
over-the-air trial was to be the next step.
