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. 2013-04-15T09:14:52Z http://hdl.handle.net/2117/16267 Title: Enhancing electronic contracts with semantics: the case of multimedia content distribution Authors: Rodríguez Doncel, Víctor; Delgado Mercè, Jaime Abstract: Multimedia content can be digitally distributed to end users or in B2B transactions. While B2C distribution has been extensively carried out by digital platforms governed by digital licenses, B2B multimedia content exchange has received less attention. The digital licenses for end users have been expressed either in proprietary formats or in standard Rights Expression Languages and they can be seen as the electronic replacement of distribution contracts and end user licenses. However RELs fail to replace the rest of the contracts agreed along the complete Intellectual Property value chain. To represent their corresponding electronic counterpart licenses, an schema based on the Media Value Chain Ontology is presented here. It has been conceived to deal with a broader set of parties, to handle typical clauses found in the audiovisual market contracts, and to govern every transaction performed on IP objects. Contract clauses are modelled as deontic logic propositions, and an event-based system is described to allow a DRM system the execution of the contract. 2012-07-17T09:55:05Z http://hdl.handle.net/2117/13867 Title: Rights management in architectures for distributed multimedia content applications Authors: Delgado Mercè, Jaime; Torres Padrosa, Víctor; Llorente Viejo, Silvia; Rodríguez Luna, Eva Abstract: 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. 2011-11-11T18:46:51Z
