Television companies realise they can really make use of the Internet
now that it’s fast and benefits from broad bandwidth and geographical
reach. They are beginning to air services not just on TVs, but also
simultaneously on PCs, tablets and smartphones – however such
integration is often limited.
Thanks to technology known as Hybrid Broadcast and Broadband TV
(HbbTV), broadcasters can offer additional internet services directly to
the TV set. Demand for broadcast and broadband integration is growing
fast, and to this day HbbTV is the only open standard to support it.
This led the European Commission to fund a project,
HBB-NEXT
, to drive the next generation of this technology. The project partners
have come up with many novel solutions, from synchronising video across
consumer devices via the cloud to controlling TVs using face and
gesture recognition technology along with innovative accessibility
solutions.
SYNCHRONISING VIDEO ACROSS SMART DEVICES
Thanks to the HbbTV standard, a plethora of new services are now
appearing across devices. These include complementary content (for
anything from elections to sports coverage), home shopping and links to
advertisers’ web pages, catch-up TV and educational courses.
‘When we started to prepare the HBB-NEXT project, the HbbTV 1.0 standard had just come in,’ explained coordinator
Bettina Heidkamp , of German public broadcaster
RBB part of the
ARD .
‘We identified several missing pieces in the user experience for
which we and our partners designed and developed solutions. These
include the personalisation and recommendation of content for users,
notably in a multi user environment, and the synchronisation of
broadband with broadcast content onto one or more screens.’
HBB-NEXT came up with novel middleware that uses the cloud where a
consumer device does not have the capability, e.g. to synchronise video.
This is not a small achievement, since even a delay of 40 milliseconds
between devices is noticed by users. ‘With HBB-NEXT, we contributed four
features that will be supported in the new HbbTV 2.0 standard hopefully
to be released later this year,’ said HBB-NEXT technical coordinator
Michael Probst, of
IRT , the German broadcasting technology institute.
HbbTV allows broadcasters to add information into their signal,
enabling a TV to load apps retrieving related content from the Internet
and displaying it on your TV. And HBB-NEXT came up with a range of novel
applications for editors’ consideration, including instant voting
(first aired on a popular TV science programme in Germany). Others,
benefiting users, permit customisation of subtitles, sign language for
the hearing-impaired, smartphone audio for the blind or partially
sighted, and services for minority languages – all of them sourced via
the Internet.
TELEVISION RECOGNISES VIEWER
The project partners also developed an app that makes
recommendations to individuals and groups of viewers about what they
should watch, combining it with face, voice and gesture recognition
technology. When a viewer, whose profile has already been loaded into
the TV, walks into the room and says ‘Hello’, the television recognises
the person and replies by suggesting programmes he or she might like to
see. A second person might then come in and both will receive their
‘group’ recommendations.
‘The face and gesture recognition achieved in the project goes
beyond what has been possible before,’ Bettina enthused. ‘It is really
innovative and people will enjoy it. It is the future, I think!’
‘As for the broadcast apps, we are now creating an HbbTV Toolbox
based on HBB-NEXT so that very soon editors will be creating them on a
day-to-day basis so that everyone can personalize and enrich the
television they are watching,’ she added.
HBB-NEXT involved representatives of the various sectors affected
economically by the advent of hybrid TV, from broadcasters and
application developers (many of whom are SMEs), to TV and consumer
electronics manufacturers, and telecoms companies.
The HBB-NEXT project comprised 9 partners from 5 countries and ran
from October 2011 to March 2014. It received 2.98 million euros from
FP7.
