The rapid increase in computing power and the speed of
communication, coupled with the availability of computer
storage facilities, has led to a new era of multimedia
applications. Multimedia is everywhere, we can feel it in
almost all applications from online video databases, IPTV
presence, interactive multimedia, social interaction based
multimedia, to the emerging Fifth Generation (5G) systems
mobile social networks which will play an important role
for disseminating information and multimedia contents [1].
These new applications require high quality data storage,
easy access to multimedia content and reliable delivery,
and are close to commercial deployment. They also arouse
a higher awareness of security and intellectual property
management issues. All of the above requirements have
put forward higher requirements for multimedia signal
processing and communications.
