    MPEG-M is a suite of ISO/IEC standards (ISO/IEC 23006) that has been developed under the auspices of Moving Picture Experts Group (MPEG). MPEG-M, also known as Multimedia Service Platform Technologies (MSPT), facilitates a collection of multimedia middleware APIs and elementary services as well as service aggregation so that service providers can offer users a plethora of innovative services by extending current IPTV technology toward the seamless integration of personal content creation and distribution, e-commerce, social networks and Internet distribution of digital media.

    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.

    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.

    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.

    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.

    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.

    We present an innovative architecture that enables the digital representation of original works and derivatives while implementing Digital Rights Management (DRM) features. The architecture’s main focus is on promoting trust within the multimedia content value networks rather than solely on content access and protection control. The system combines different features common in DRM systems such as licensing, content protection, authorization and reporting together with innovative concepts, such as the linkage of original and derived content and the definition of potential rights. The transmission of reporting requests across the content value network combined with the possibility for authors to preserve rights over derivative works enables the system to distribute income amongst all the actors involved in different steps of the creation and distribution chain. The implementation consists of a web application which interacts with different external services plus a desktop user application used to render protected content. It is currently publicly accessible for evaluation.

    The Web contains many digital multimedia creations prepared for being consumed by final users. Nevertheless, in many cases, these users need the appropriate rights to do so. Licenses and rights can be digitally associated to multimedia content, as well as to other metadata, like the author(s)’ name(s), the date where it was produced, the time when it was created, its title, the person or organisation who owns exploitation rights, etc. The aim of the work presented in this paper is to find rights and licenses, among other metadata, in the Web, by using semantic web techniques. In case there is no license or it cannot be used by anyone (for instance, public domain license), we will try to find out the necessary information for getting a license, that is, the author, the rights owner or whoever who has the ability to provide us with a license over a digital content.
