One can identify principles, concepts and theories from communication and computer science, physics, psychology, music, graphic arts and many other disciplines in such data [Tannenbaum, 1999]. In addition, multimedia are renowned for their rich character, stemming from their formation based on combination of different content forms. The widespread penetration of digital capturing and processing devices and the high bandwidth interconnections between web-users, coupled with the aforementioned multidisciplinary and rich character of multimedia, led their use to be a sine qua non in many forms of digitised expression. Setting aside the enormous expansion of use of multimedia content in web pages under the auspices of Web 2.0, the most prominent example of the ever-increasing use of multimedia comes from socially aware and contextually rich video streaming services. In both terms of creating and consuming such content, YouTube service [YouTube, 2012] states that "48 hours of video are uploaded every minute, resulting in nearly 8 years of content uploaded every day, while over 3 billion videos are viewed a day". Although research in the discipline of multimedia is far from young, such growth of multimedia content creation and consumption is unprecedented and calls for new methods in order to ensure efficiency and effectiveness of the methods utilised. In addition, latest developments in terms of hardware, networking issues, security and semantic information extraction require re-evaluation of the currently used techniques to suit new requirements. This book is organised into 5 major sections addressing multimedia topics in peer-to- peer & wireless networks, security characteristics in multimedia, semantic gap bridging for multimedia content and novel applications for managing multimedia content & metadata.
