The rapid increase in computing power and communication speed,
coupled with computer storage facilities availability, has led to a
new age of multimedia app- cations. Multimedia is practically
everywhere and all around us we can feel its presence in almost all
applications ranging from online video databases, IPTV, - teractive
multimedia and more recently in multimedia based social
interaction. These new growing applications require high-quality
data storage, easy access to multimedia content and reliable
delivery. Moving ever closer to commercial - ployment also aroused
a higher awareness of security and intellectual property management
issues. All the aforementioned requirements resulted in higher
demands on various - eas of research (signal processing,
image/video processing and analysis, com- nication protocols,
content search, watermarking, etc.). This book covers the most
prominent research issues in multimedia and is divided into four
main sections: i) content based retrieval, ii) storage and remote
access, iii) watermarking and co- right protection and iv)
multimedia applications. Chapter 1 of the first section presents an
analysis on how color is used and why is it crucial in nowadays
multimedia applications. In chapter 2 the authors give an overview
of the advances in video abstraction for fast content browsing,
transm- sion, retrieval and skimming in large video databases and
chapter 3 extends the discussion on video summarization even
further. Content retrieval problem is tackled in chapter 4 by
describing a novel method for producing meaningful s- ments
suitable for MPEG-7 description based on binary partition trees
(BPTs).

Last few years have seen rapid acceptance of high-definition
television (HDTV) technology around the world. This technology has
been hugely successful in delivering more realistic television
experience at home and accurate imaging for professional
applications. Adoption of high definition continues to grow as
consumers demand enhanced features and greater quality of content.
Following this trend, natural evolution of visualisation
technologies will be in the direction of fully realistic visual
experience and highly precise imaging. However, using the content
of even higher resolution and quality is not straightforward as
such videos require significantly higher access bandwidth and more
processing power. Therefore, methods for radical reduction of video
bandwidth are crucial for realisation of high visual quality.
Moreover, it is desirable to look into other ways of accessing
visual content, solution to which lies in innovative schemes for
content delivery and consumption. This book presents selected
chapters covering technologies that will enable greater flexibility
in video content representation and allow users to access content
from any device and to interact with it.
