This book constitutes the thoroughly refereed post-conference proceedings of the 7th International ICST Conference on Mobile Multimedia Communications (MOBIMEDIA 2011) held in Cagliari, Italy, in September 2011 The 26 revised full papers presented were carefully selected from numerous submissions and focus topics such as quality of experience, dynamic spectrum access wireless networks in the TV white spaces, media streaming, mobile visual search, image processing and transmission, and mobile applications.

This book constitutes the refereed proceedings of the 4th International Workshop on Mobile Agents for Telecommunication Applications, MATA 2002, held in Barcelona, Spain, in October 2002. The 28 revised full papers presented were carefully reviewed and selected for inclusion in the proceedings. The papers are organized in topical sections on agent architecture, framework, and platforms; mobile agent frameworks for telecommunication services; mobile agents in active networks; context-aware and ad-hoc communications; distributed monitoring and network management; security of mobile agents; mobile computing and QoS; migration and network management; mobile services; and collaborative environments and services.

Creation Techniques for Software Development and Deployment, Agent-Based Management, Virtual Home Environment, Integrated and Scalable Solutions for Telecommunications Management. This shows that the issues related to communications management, architectures, and service creation are still of great interest, while the virtual home environment is emerging as a new key topic in IS&N. In summary, this book reflects the state of the art in research on IS&N topics, with the focus mentioned above, not only from European Union co-funded projects (mainly in the ACTS programme), but also from research organisations around the globe.

Since then, the IS&N conferences have been held almost every year, with proceedings published as part of the Lecture Notes in Computer Science (LNCS) series of Springer-Verlag. These are as follows. "Towards a Pan-European Telecommunication Service Infrastructure - IS&N'94", Hans-Jiirgen Kugler, Al Mullery, Norbert Niebert (Eds.), Aachen, Germany, September 1994, LNCS 851, ISBN 3-540-58420-X. "Bringing Telecommunication Services to the People - IS&N'95", Anne Clarke, Mario Campolargo, Nikos Karatzas (Eds.), Heraklion, Greece, October 1995, LNCS 998, ISBN 3-540-60479-0. "Intelligence in Services and Networks: Technology for Cooperative Competition - IS&N'97\ Al Mullery, Michel Besson, Mario Campolargo, Roberta Gobbi, Rick Reed (Eds.), Cernobbio, Italy, May 1997, LNCS 1238, ISBN 3-540-63135-6.

Paving the Way for an Open Service Market We live in an age when powerful communications technology is becoming available to everyone. From our home we can send and receive not only analogue voice, but also growing volumes of digital information and even intelligence in the form of agents. We are becoming increasingly mobile and are expecting the same level of connectivity in the home, in the office, and on the road. The regulatory and commercial environment in which we communicate is changing. The telecommunications market is becoming increasingly competitive. The Internet is erasing the borders between information technology and telecommunications. And the way we do business is ever more dominated by electronic exchanges of information. Is our technology ready for the open market of networks and services? Can we manage the growing complexity of computing and telecommunications technology and place it at the service of the people? The challenge for the research community is to develop the tools and techniques that will ultimately bring the full power of communications and information to everyone, in a way that everyone can easily use. The Sixth International Conference on Intelligence in Services and Networks (IS&N 99) is all about technology for paving the way to the open services market. Since the first IS&N conference in 1992 the focus of the IS&N program has continually shifted. We see existing technologies maturing while new ones emerge, but the bottom line has always been putting technology at the service of the people."

Is the author of an original work the owner of its intellectual property rights? Can the exploitation rights be traded and handed over different people, eventually transforming the original work? If so, a media value chain can be defined where the different parties exchange rights and content in a fair environment acknowledging a common model. With this model, IT systems may interoperate more easily and may grant that intellectual property is respected. The Media Value Chain Ontology represents such a model, and it has become part of the MPEG-21 standard, a Multimedia Framework where any digital content can be protected, licensed and consumed. This PhD Thesis was an important contribution for the development of the standard, and those interested in their inception will find this book very useful. On despite of being a formal work, the text is enriched with multiple examples and figures and it can be easily followed by readers interested either in the MPEG-21 world, the architecture of rights-aware content distribution systems, electronic contracts representation or ontologies in general.

The starting point of this book is the work developed within the Xarxa IP Audiovisual de Catalunya (XAe project in 2005-2006, in which a group of content producers (mainly local televisions (TVs)) wanted to have the means of exchanging their multimedia contents. From the obtained results, we could identify a number of important issues that still needed to be addressed. Furthermore, our contributions should be extensible to a generic distributed multimedia scenario. Thus, our foremost requirement was to use open standards. In line with the open issues previously identified, this book presents five independent but related contributions. Our first Contribution presents a proposed adaptation authorisation technique based on MPEG-7 descriptors. Our second Contribution presents the identification of a complete standardised set of context descriptors, and an innovative approach for modelling them based on profiles. Our third Contribution presents a novel adaptation authorisation process based on the context profiles specified in Contribution 2 which improves the efficiency of the adaptation authorisation presented in Contribution 1.
