Finally, we also employed the same approach in this chapter to evaluate these
three metrics for normal size images using the LIVE image quality database.. We
tested the JPEG 2000 compression distortion type, as well as three other distortion
types: Gaussian blur, JPEG compression and white noise. The performance was,
however, worse than the original methods either for JPEG 2000 compression or
other distortion types. We believe that the cause is due to the fact that the mecha-
nisms are different when subjects assess the image quality between a normal size
monitor and a large screen in a digital cinema setup. The future work will be fo-
cused on an in depth analysis of the differences of the visual quality assessment
between a normal scenario with normal size displays and a digital cinema system,
and development of more suitable metrics for digital cinema.
5 Quality as Part of the Business Plan
For a media presentation to be possible, the most important process is of course
the creative one, created by the artist and represented by the content provider or
content aggregator. One of the predominant slogans recently in the media industry
has been “Content is king”, which, certainly, has been used as one of the driving
forces for digitization and development of new services and applications.
Even more recently, following the rapid deployment of wireless services, more
focus has been put on the delivery. As slogan goes, the novelty is represented by
“Connectivity is Queen”.
Our claim, however, is contrary to this, and assumes all providers have one
goal in common, the satisfied and loyal customer, buying and consuming their
services and applications regardless of technology, simply meaning that the “User
is president”. The hypothesis is that a satisfied user gets his/her expectations ful-
filled and that expectations are connected to the experience of the media as repre-
sented by the QoE. Although QoE currently is not an objectively measurable
parameter, we will assume that this is represented by our broader understanding of
the term
Quality
. High quality gives more satisfied customers and a better experi-
ence than poor quality.
5.1 Case: D-Cinema
The motivations for D-Cinema were at least three fold:
•
To reduce distribution costs (benefits for studios)
•
To reduce piracy (benefits for studios)
•
To enhance Quality of Experience (benefits for cinema goers - the users)
Several other motivating factors have become more and more important as the in-
novators and early adopters are implementing D-Cinema. Some of these were
planned; some again are spin-off innovations. Examples of these are 3D and Other
Digital Stuff - ODS (Alternative Content).
D-Cinema roll out has hit a crucial moment in time since reaching the famous
chasm of diffusion of innovation simultaneously with the global financial crisis.
