suited to many auto-stereoscopic approaches (see Section 5.4.4 for a more
detailed description of this technology), which often require that the viewer
positions themselves within a 'sweet spot' to view the video in 3D.
Commercial mobile devices with 3D displays are already starting to find
their way to the market. Although not a mobile phone, Nintendo's 3D DS
portable games platform is an interesting example of a small device with a
3D display. Manufacturers such as Samsung and Nokia have already begun
to produce experimental mobile phones with 3D capability. In addition to
this, research funded by the European Union has brought together coalitions
of industry and academia to work on the following two projects:

• 3DPHONE - examines various topics relevant to future 3D mobile phones,

such as auto-stereoscopic displays, stereoscopic capture of video, 3D user
interfaces, and compression of 3D video. The project partners are Bilkent
University, Fraunhofer Heinrich-Hertz-Institute (HHI), Holografika, TAT
(The Astonishing Tribe), Telefonica and University of Helsinki.

• MOBILE 3DTV - investigates how to deliver 3DTV services to a mobile

hone with an auto-stereoscopic display, over DVB-H. Special attention is
paid in the project to quality issues. The project partners are Tampere
University of Technology, Technische Universitt Ilmenau, Middle East
Technical University, Fraunhofer HHI, Multimedia Solutions Ltd and
Tamlink Innovation-Research-Development Ltd.

Both of the above-named projects have successfully demonstrated 3D mobile
phone technology, and have carried out user trials showing strong user
acceptance.

1.3.3 3DVideoonDemand

3D Video on Demand involves the delivery of video over Internet Protocol
(IP)-based networks, when requested by the user. In the United Kingdom,
Video on Demand has become popular, and has been branded for the public
using names such as iPlayer, and Catch-Up TV. Many television sets are now
being produced that are capable of being connected to the Internet to view
VoD. The Consumer Electronics Show (CES) in 2011 featured a large number
of so-called 'connected TVs', and Forrester Research predicts that [45]:

Internet connected TVs will continue their steady penetration into con-
sumers' homes, in large part due to retailers' commitment to only sell
connected TVs in the future.

Forrester estimates that 58 per cent of all TVs sold will be 'connected' by 2015.
Of course, if these connected TVs are also capable of displaying 3D, then
the extension of these 2D video services to 3D is relatively trivial. Service
providers can either use the frame compatible formats currently in use for
