In this paper, we present current state and aims of our ongoing research aimed at advanced interactive multimedia and mulsemedia delivery in 5G networks. We summarize the underlying and necessary properties of 5G networks, architecture of SDN/NFV and their usage in the multimedia and mulsemedia delivery. Advanced topics as content adaptation and user identification are discussed. Preliminary results regarding algorithms for content adaptation are presented. We show the advance of usage of AR/VR headsets as effective terminal for immersive application for this kind of delivery and discuss the advantages and disadvantages. We propose corresponding system architecture for advanced interactive multimedia delivery in 5G networks.
The fast growing progress in data communication leads to a wide variety of available access technologies that provide everything from mobile data transfer to high-speed data links using fibre optics. Due to this fact ...

The embedded devices like the mobile Internet continue to pursue new multi-media features with advanced networks. The emerging diversity of the content languages adds a new challenge in addition to the sustained challenge from the diversity of the execution environments in the embedded environment. The author describes the past three-stage evolution of micro-browsers in the embedded environment. In order to leverage embedded multimedia applications, it is necessary to provide software architecture for a wide range of multimedia applications for the future embedded environment, e.g. mobile handsets, game consoles, and automotive systems. With the sustained focus to the resource constraint, the author proposes an application toolkit framework that enables multimedia applications including browsing, mail clients, stand-alone multimedia players. The toolkit approach provides a footprint optimized multimedia applications in an OS-agnostic manner.

The paper presents the solution adopted to index the information in a multimedia Database Management System dedicated to medical domain, being optimized for medium sized databases. The system automatically processes the images inserted into database, extracting characteristics as: color histogram, texture, and color regions. The system contains the needed algorithms for images processing and visual content-based retrieval, thus making the client applications less complex. The information is indexed using a single level B-tree structure for text-based data, and using an R-trees structure for multimedia data. The performances of the system are analyzed from the execution time point of view.

In this work we propose all intuitive graphic framework for the effective visualization of MPEG-7 low-level features, in the context of classification and annotation of audio-visual documents. This graphic tool is proposed to facilitate the access to the content, and to improve a quick understanding of the semantics associated to the considered document. The main visualization paradigm employed consists in representing a 2D feature space in which the shots of the audiovisual document are located. In another window, the same shots are drawn in a temporal bar that gives the users also the information related to the time domain. In the main window, shots with similar content fall near each other, and the proposed tool offers various functionalities for automatically and semi-autonmatically finding and annotating shot clusters in the feature space. The use of the proposed system to analyze the content offew video sequences has shown very interesting capabilities.
multimedia services are becoming increasingly popular among mobile users. Ontology and related technologies have been introduced into the multimedia domain as a means to provide declarative formal representations of t...

This paper presents the experimental design and implementation of Swarm, an integrated and scalable multimedia delivery platform. Swarm offers the adaptability, maintainability and scalability required to effectively support diversity in network and client access, including the provisioning for mobile devices. Based upon a topologically aware peer-to-peer substrate, comprised of a distributed set of cooperating nodes and a novel routing schemata, Swarm allows for the effective maintenance of multimedia transactions despite the dynamic properties introduced by wireless and mobile systems. We present the Swarm design, with particular emphasis on how the system maintains content and structural integrity whilst adaptability and dynamic stresses are prevalent. Finally, the experimental implementation of Swarm is discussed together with an analysis of its performance.

Despite the great potential demonstrated by the multimedia-rich data in various business applications, none of the prior research has addressed the design of high-quality access to the multimediacontent in heterogeneous wireless networking environment. In this research, we have presented a partial pre-retrieval and buffering scheme to improve various quality of service (QoS) parameters for multimediacontent for in such context. Specifically it addresses the three important QoS parameters namely delay, delay variation, and information loss that directly impact the mobile user's quality of experience indicators. Here we have also presented the analysis of the buffering requirements and the related issues for high-quality access to the multimediacontent in such environment. Results of this research have potential to improve the understanding of these multimedia QoS parameters for ubiquitous wireless infrastructures. Copyright 2005 ACM.

We propose an access pattern-driven distributed caching middleware named APRICOD, which can be built on top of any existing content discovery system. APRICOD caters for fast and scalable content discovery in peer-to-peer media streaming systems, especially when user interactions that leads to non-continuous media access (such as random seek in video and teleportation in virtual environment) are present. APRICOD caches query results based correlations among media objects accessed by users, reducing the content discovery time. Our evaluation using a VoD access trace shows that close to 70% of non-continuous access queries can be resolved with a single hop using APRICOD. Copyright 2011 ACM.

This paper deals with concept of protected access to multimedia with respect to rights management of transmitted content. Presented technologies are ready to be implemented and fulfill the needs of most of Internet Service Providers for video on demand service to customers with respect legal issues given by content owners. With numbers of users using mobile devices for streaming delivery there is need to implement new authentication models and methods. This paper presents some ideas based on features provided by modern mobile operating systems. Part of this work presents Videoserver platform developed by Computer Networks Laboratory at Technical University in Kosice. Videoserver platform serves as testbed for developing new solutions for better content handling and for providing secure access to content. Paper is focused mostly on outlines of possible solutions to open problems.
