“…Besides this, since the integrated system handles, encodes, and presents multimedia content coming from different vendors, the respective intellectual property rights (IPR) must be retained throughout the complete process. These two additional requirements can be dealt with successfully via the inclusion of concepts presented within the MPEG21 framework, introducing additional middleware components which mediate the production, transmission, and playback phases, thereby respecting the established production process; a more detailed description of the initial processlevel architecture is provided in [24].…”

The abundance of broadcast material, especially when it becomes available from a variety of content providers, makes the choice of a program genre and adaptation of presentation options to the preferences of a user, a welcome feature of the modern-day TV viewing experience. From a technical point of view, assembling and transmitting such heterogeneous content is in itself a daunting task, especially when intellectual property rights issues should be tackled. In addition to this, while there are a lot of options for filtering content with respect to the preferences of a single user, the common or aggregated choice of a group is hardly ever taken into account. Considering the fact that TV viewing and multimedia consumption in general are essentially a social activity, systems which package, filter and rank the available content or propose similar content to what is currently viewed should also integrate mechanisms to model group dynamics. This article presents an integrated, end-to-end architecture which assembles multimedia material, respecting the IPR of the content provider, and delivers it to a client-side mechanism which considers the preferences of all the viewers currently watching to filter and rank the available programs. In order to respect the established methods of producing content, this system utilizes concepts from adopted standards (MPEG7, MPEG21) to model processes and represents data and relations between the different entities of the system.

“…Figure 1 shows only an overview of the higher-level information flow, between the different framework components. The reader is encouraged to find a detailed description of the complete process level architecture framework in (Papaioannou, 2004). The basic idea is that content is adapted to the different terminals and transmission networks targeted by the proposed framework and then delivered via the respective transmission channels.…”

“…Its core contribution relies on the fact that it provides a personalized delivery of content over heterogeneous networks and terminals, using the core functionality of the MPEG-21 standard and providing the missing link for an integrated personalized interactive experience. The latter is achieved by utilizing the notion of an MPEG-21 Digital Item (Papaioannou, 2004), using it to encapsulate personalization-useful information at the multimedia content level and not at the level of terminal or system. In this context, a user is any entity that interacts with or makes use of a Digital Item.…”

Abstract:In this paper we present an integrated framework for personalized access to interactive entertainment content, using characteristics from the emerging MPEG-21 standard. Our research efforts focus on multimedia content presented within the framework set by today's movie content broadcasting over a variety of networks and terminals. This work contributes to the bridging of the gap between the content and the user, providing end-users with a wide range of real-time interactive services, ranging from plain personalized statistics and optional enhanced in-play visual enhancements to a fully user-and contentadaptive platform. The proposed approach implements and extends a well-known collaborative filtering approach; it applies a hierarchical clustering algorithm on the data towards the scope of group modelling implementation. It illustrates also the benefits from the MPEG-21 components utilization in the process and analyzes the importance of the Digital Item concept. Finally, a use case scenario is presented to illustrate the entire procedure. The core of this work is the novel group modelling approach, on top of the hybrid collaborative filtering algorithm, employing principles of taxonomic knowledge representation and hierarchical clustering theory. The outcome of this framework design is that end-users enhance their personalized viewing experience.

Abstract. In the paper the first stage of the approach for automatic identification of football players is presented. It is based on the numbers placed on their shirts. The method works with video frames extracted during a television sport broadcast. The element of the system described in this paper is devoted to the localisation of the numbers and their extraction for future recognition. It is simple, yet efficient and it is based on the use of appropriate ranges in various colour spaces. Four colour spaces were experimentally evaluated for this purpose. Thanks to this, the ranges could be established for particular kits. Firstly, the part of an image with a shirt was localised, and later, within this area, a number was found.
