    El objetivo principal del trabajo presentado en esta tesis es el de describir la definición de mecanismos de interoperabilidad entre lenguajes de expresión de derechos y lenguajes de políticas. Empezando con la interoperabilidad entre lenguajes, se quiere ir un paso más allá y definir cómo servicios para la gestión de contenidos multimedia pueden interoperar por medio de arquitecturas estándares orientadas a servicios.Para conseguir este objetivo, varios estándares e iniciativas existentes se van a analizar y ser tenidas en cuenta. Respecto a los lenguajes de expresión de derechos y de políticas, se han considerado estándares tales como MPEG-21 Rights Expression Language (REL), Open Digital Rights Language (ODRL) y eXtensible Access Control Markup Language (XACML). Respecto a los servicios para la gestión del contenido multimedia, se han considerado la plataforma Multimedia Information Protection And Management System (MIPAMS), una implementación de una arquitectura basada en estándares, y el estándar Multimedia Service Platform Technologies (MSPT), también conocido como el estándar MPEG-M. La contribución de esta tesis se divide en dos partes, una dedicada a la interoperabilidad entre lenguajes y la otra dedicada a la interoperabilidad entre services, ambas dirigidas a la gestión de contenido multimedia. Se describen a continuación.La primera parte de la contribución describe cómo MPEG-21 REL, ODRL y XACML pueden interoperar, definiendo los mecanismos para traducir expresiones de lenguaje a lenguaje. Los mapeos proporcionan distintos niveles de granularidad, empezando por un mapeo basado en una solución programática basada en diagramas realizados con lenguajes de modelado de alto nivel como pueden ser Unified Modelling Language (UML) y Entity-Relationship (ER). El siguiente nivel de mapeo incluye mapeos específicos entre MPEG-21 REL y XACML y ODRL y XACML. Finalmente, se plantea una solución más general con el uso de un bróker. Parte de este trabajo se ha realizado en el contexto de la Red de Excelencia VISNET-II y del Proyecto Integrado AXMEDIS. Los resultados obtenidos avalan la validez de los métodos de interoperabilidad descritos.La segunda parte de la contribución describe cómo definir standards based building blocks (SB3) para proporcionar interoperabilidad entre servicios para la gestión del contenido multimedia. Esta definición se basa en el análisis de casos de uso existente para la gestión de contenido, desde los que necesitan menos seguridad sobre el contenido gestionado hasta los que requiere una gestión completa de los derechos digitales (DRM, digital rights management), incluyendo técnicas de control de acceso y cifrado, para soportar gestión segura del contenido. En esta sección también se presenta el trabajo realizado en los proyectos de investigación AXMEDIS, Musiteca y Culturalive. Además, se describe el trabajo de estandarización realizado en MPEG-M, especialmente en Elementary Services y Service Aggregation. Para demostrar el uso de ambas tecnologías se presenta una aplicación móvil que integra MPEG-M y MIPAMS.Además, se presentan las conclusiones y las líneas de trabajo futuro en la sección correspondiente, junto con las publicaciones asociadas a esta tesis, que se describen en el documento. En resumen, el trabajo presentado puede seguir diversas líneas de investigación. Por un lado, es necesario estudiar las nuevas versiones de los lenguajes de expresión de derechos y políticas aparecidos recientemente. Además, también habrá que tener en cuenta el lenguaje de expresión de contratos, MPEG-21 CEL, estandarizado recientemente, con el objetivo de evaluar la interoperabilidad con los lenguajes de expresión de derechos y políticas. Por otro lado, se deben seguir distintas iniciativas de estandarización para completar el mapa de SB3¿s, considerando estándares MPEG y otros no sólo relacionados con multimedia sino también con otros escenarios de aplicación como e-salud y e-gobierno.

    The main goal of the work presented in this thesis is to describe the definition of interoperability mechanisms between rights expression languages and policy languages. Starting from languages interoperability, the intention is to go a step further and define how services for multimedia content management can interoperate by means of service-oriented generic and standardised architectures. In order to achieve this goal, several standards and existing initiatives will be analysed and taken into account. Regarding rights expression languages and policy languages, standards like MPEG-21 Rights Expression Language (REL), Open Digital Rights Language (ODRL) and eXtensible Access Control Markup Language (XACML) are considered. Regarding services for content management, the Multimedia Information Protection And Management System (MIPAMS), a standards-based implemented architecture, and the Multimedia Service Platform Technologies (MSPT), also known as MPEG-M standard, are considered. The contribution of this thesis is divided into two parts, one devoted to languages interoperability and the other one devoted to services interoperability, both addressed to multimedia content management. They are briefly described next. The first part of the contribution describes how MPEG-21 REL, ODRL and XACML can interoperate, defining the mapping mechanisms to translate expressions from language to language. The mappings provided have different levels of granularity, starting from a mapping based on a programmatic approach coming from high-level modelling diagrams done using Unified Modelling Language (UML) and Entity-Relationship (ER). The next level of mappings includes specific mappings between MPEG-21 REL and XACML and ODRL and XACML. Finally, a more general solution is proposed by using a broker. Part of this work was done in the context of the VISNET-II Network of Excellence and the AXMEDIS Integrated Project. The findings done prove the validity of the interoperability methods described. The second part of the contribution describes how to describe standards based building blocks to provide interoperable services for multimedia content management. This definition is based on the analysis of existing content management use cases, from the ones involving less security over multimedia content managed to the ones providing full-featured digital rights management (DRM) (including access control and ciphering techniques) to support secure content management. In this section it is also presented the work done in the research projects AXMEDIS, Musiteca and Culturalive. It is also shown the standardisation work done for MPEG-M, particularly on elementary services and service aggregation. To demonstrate the usage of both technologies a mobile application integrating both MPEG-M and MIPAMS is presented. Furthermore, some conclusions and future work is presented in the corresponding section, together with the refereed publications, which are briefly described in the document. In summary, the work presented can follow different research lines. On the one hand, further study on rights expression languages and policy languages is required as new versions of them have recently appeared. It is worth noting the standardisation of a contract expression language, MPEG-21 CEL, which has also to be further analysed in order to evaluate its interoperability with rights and policy languages. On the other hand, standard initiatives must be followed in order to complete the map of SB3's, considering MPEG standards and also other standards not only related to multimedia but also other application scenarios, like e-health or e-government.

    The research around visual search is gaining relevance due to the evolution in the generation and usage of digital images. A significant push comes from the mobile visual search topic, due to the widespread proliferation of camera enabled mobile devices. The new scenarios are increasing the urgency of novel solutions for challenging problems such as the efficient coding of compact visual descriptors and the interoperability of distributed visual search query interfaces. Currently, almost every visual search service offers a different retrieval interface and image metadata description format, preventing unified and efficient access. In this context, standardization groups such as ISO/IEC SC29/WG11 (MPEG) and ISO/IEC SC29/WG1 (JPEG) have been working to create unified interfaces for image repositories. In one hand, MPEG provides the ISO/IEC 15938-12 (MPEG Query Format, MPQF), which standardizes a query language for multimedia repositories and has also started an activity for standardizing compact descriptors for visual search (CDVS). On the other hand, JPEG is now finishing the ISO/IEC 24800 (JPSearch), which provides solutions to the image metadata interoperability problem. This paper analyzes how these standardization activities can be combined to satisfy the requirements posed by the mobile visual search scenario, which are their limitations and which are the necessary actions to be taken by the standardization committees in order to overcome them.

    Controlling, protecting and managing access to multimedia content could be a difficult task if a system was not prepared for it. To solve this situation minimizing the impact on the existing system, we propose the use of a modular architecture which provides digital rights and privacy policies management features. It can be integrated just invoking some web service calls, depending on which services are needed. To show its use, we present several scenarios where we have successfully integrated it, like distribution of content for digital terrestrial television broadcasting and access to personal health information.

    In the present paper, we describe the work being carried out by a group of professors so as to implement the follow-up and feedback processes of the activities students do throughout the first academic years in their Engineering studies. Not to mention, this project is within the EHEA (European Higher Education Area) framework. Our results show that these processes are key to enhance students learning, they can also have an impact in their academic performance and can be optimized in such a way that professors can assume the time it requires.

    The digital content industry is facing significant challenges. One of the most significant challenges is the Intellectual Property protection. This challenge has been addressed technologically by using Digital Rights Management (DRM) systems that on a first stage ensured the appropriate management over digital content. However, rights management systems, as they are today, are completely non-interoperable, creating immense problems to the digital content final users. Perhaps one of the biggest problems is the fact that the same digital content that is governed by different rights management systems cannot be exchanged between different rights governance systems. This paper presents some of the work that has been performed under the framework of the VISNET-II Network of Excellence (NoE) to address some of the rights management systems interoperability problems. The approach followed by the proposed work consists on the usage of service description and service-oriented architectures as a mean to create a common and interoperable environment between the different systems.

    There are several initiatives working in the definition and implementation of distributed architectures that enable the development of distributed multimedia applications on top of them, while offering Digital Rights Management (DRM) features. In this chapter, the main features of the MPEG Extensible Middleware (MXM) (ISO/IEC, http://mxm.wg11.sc29.org, 2010) and the new Advanced IPTV terminal (AIT) (ISO/IEC, ISO/IEC JTC1 SC29/WG11 N11230, 2010), which together will form a future second edition of the MXM standard (renamed to Multimedia Service Platform Technologies) are presented. On the other hand, the DMAG’s (Distributed Multimedia Applications Group (DMAG), http://dmag.ac.upc.edu, 2010) Multimedia Information Protection and Management System (MIPAMS) (Torres et al., Springer, Heidelberg, 2006) is also presented, highlighting the common ground and differences between MIPAMS and the standards. A set of usage scenarios is also proposed to show how MIPAMS enables the development of applications, on top of it, which deal with the needs of content creators, distributors and consumers according to different business models.

    This paper describes several scenarios for the management of digital media, focusing on electronic publishing from mobile environments. The solution proposed in those scenarios is based on MIPAMS (Multimedia Information Protection And Management System), a service-oriented Digital Rights Management (DRM) platform, which enables the creation, registration and distribution of multimedia content in a secure way, respecting intellectual property rights. The particularity of the mobile scenario with respect to others is the limited capability of mobile devices. A specific use case has been identified for the mobile environment and a new system, based on MIPAMS, has been designed for the electronic publishing environment.

    New mobile devices (pda’s, tablets) permit the implementation of new business models as they are always connected and provide multimedia capabilities for capturing images, videos, music or even conversations. Together with an architecture for the secure management and distribution of multimedia content called MIPAMS, we propose a mobile business model with the implementation of a mobile application based on iOS (Apple operating system for mobile devices) for publishing added value content captured with a mobile device.

    La evaluación es un elemento que preocupa siempre a todos los implicados en el proceso educativo (profesores, alumnos, responsables académicos, etc.). Sin embargo, la evaluación es un concepto muy amplio y no todas sus facetas preocupan de igual manera ni reciben la misma atención. Evaluar, desde luego, es asignar una calificación que refleje el nivel de aprendizaje. Pero evaluar es también identificar lo que debe mejorarse de cara al curso siguiente. En nuestro artículo, partiendo del modelo de Donald Kirkpatrick sobre los diferentes enfoques de la evaluación, describimos las estrategias y técnicas que utilizamos en la actualidad para desplegar un sistema de evaluación de amplio alcance, en el contexto del proceso de adaptación de nuestras asignaturas de primeros cursos de ingeniería a los requerimientos del Espacio Europeo de Educación Superior (EEES). Precisamente en el contexto del EEES algunos enfoques de la evaluación a los que normalmente se presta poca atención, como es el caso de la evaluación del seguimiento de la actividad del alumno, adquieren una relevancia muy importante.

    This paper describes how do we use our digital campus based on Moodle as a key tool in our subjects. These subjects belong to a first course in an engineering degree and have been adapted to the requirements of the European Higher Education Area in accordance with an educational model whose essential elements are the detailed planning of student work, both in class and out of class, and the evaluation of student work with frequent feedback. Our experience indicates that the digital campus has become an essential tool that allows us to be very productive in implementing the educational model, in a scenario with several groups of class and several teachers teaching the same program. This paper describes our educational model and how few resources our Moodle based digital campus are used to support key elements of this model.

    Context-aware applications are becoming very popular as they are a mean of enriching users' experiences in multimedia scenarios. Nevertheless, the acquisition, representation, and protection of contextual information are still open issues that need to be addressed. These are significant topics of interest mainly due to today's growing concern on user privacy, and are particularly relevant in the context of Social Networks. In this paper, we briefly present our work development within the Visnet-II Network of Excellence (NoE) on context acquisition and protection for context-based content adaptation. We identify the sensitive contextual information used within Social Network application scenario, and then specify a suitable privacy model. Finally, we describe how this model could be implemented through the use of the MPEG-21 Rights Expression Language (REL) Standard.

    En este trabajo se expone el proceso que se ha llevado a cabo para la elaboración del plan de mejora en la asignatura de Introducción a los Ordenadores (grado en Ingeniería de Sistemas de Telecomunicación y grado en Telemática, EPSC). La elaboración del plan de mejora se realiza una vez ha finalizado el periodo de impartición de la asignatura, parte del conjunto de datos y evidencias que los profesores de la asignatura han ido recogiendo a lo largo del curso así como de la relación de acciones no previstas (correcciones) llevadas a cabo durante el mismo (medida y seguimiento del proceso de enseñanza-aprendizaje) y consta de tres etapas: análisis de los datos, análisis de la información y establecimiento de acciones de mejora. El análisis de datos tiene como objetivo transformarlos en información. Cada uno de los datos recogidos es una afirmación aislada de la realidad pero la información es un conjunto de datos a los que se ha asociado un significado. Este análisis requiere seleccionar, organizar y presentar el conjunto de datos y evidencias disponibles de forma que facilite la posterior extracción de conclusiones útiles. La segunda etapa transforma la información en conocimiento. En esta fase se determinan las debilidades, amenazas, fortalezas y oportunidades (análisis DAFO) del proceso de enseñanza-aprendizaje de la asignatura, comparando los resultados obtenidos con los objetivos previstos (tanto objetivos de aprendizaje como objetivos relativos a rendimiento académico, tiempo de dedicación del estudiante o satisfacción del mismo). En esta etapa también se determinan las causas de las debilidades y amenazas. En la tercera y última etapa, se determina qué debilidades se quieren corregir, que amenazas se quieren prevenir y que oportunidades se quieren aprovechar (priorización), y se determinan las acciones a implementar (correctoras, preventivas o de mejora).

    Social Networks, as the main axis of Web 2.0, are creating a number of interesting challenges to the research and standardisation communities. In this paper, we analyse the current and future use of access control policies in Social Networks. Subsequently, two main issues are addressed: the interoperability amongst systems using different policy languages and the lack of elements in the existing policy languages when trying to express Social Networks’ access control. In particular, our approach is based on the use of the XACML standard.

    Digital objects are managed in a controlled way through the complete value chain by DRM systems. Access Control Frameworks manage access by users to resources. This paper presents a solution that enables users of both systems to work collaboratively. It is based on the definition of an interoperability Broker that provides users of both systems with transparent access and use of content taking into account users’ roles and content usage rules. It consists of modules that provide interoperability between digital rights and access control rules, between protected digital objects and digital resources and to manage the user’s roles in both systems
