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.

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.

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.

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.
