The management,of the vast amount of media assets captured at every day events such as meetings, birthday parties, vacation, and conferences has become an increasingly challenging problem. Today, most media management applications are media-centric. This means, they put the captured media assets into the center of the management. However, in recent years it has been proposed that events are a much better abstraction of human experience and thus provide a more appropriate means for managing media assets. Consequently, approaches that include events into their media management solution have been explored. However, they typically consider events only as some more metadata that can be extracted from the media assets. In addition, today's applications and approaches concentrate on particular problems such as event detection, tagging, sharing, classification, or clustering and are often focused on a single media type. In this paper, we argue for the benefits of an event-centric media management (EMMa) approach that-looks at the problem of media management holistically. Based on a generic event model, we specify a media event model for-the EMMa approach. The single -phases and processes of the EMMa approach are defined in a general process chain for-an event-centric media management, the EMMa cycle. This cycle follows the event concept throughout all phases and processes of the chain and-puts the concept of events in the center of the media management. Based on the media event model and EMMa cycle, we design a component-based architecture for the EMMa approach and conduct an implementation of the approach.

Purpose - The growth of the web and the increasing number of documents electronically available has been paralleled by the emergence of harmful web pages content such as pornography, violence, racism, etc. This emergence involved the necessity of providing filtering systems designed to secure the internet access. Most of them process mainly the adult content and focus on blocking pornography, marginalizing violence. The purpose of this paper is to propose a violent web content detection and filtering system, which uses textual and structural content-based analysis. Design/methodology/approach - The violent web content detection and filtering system uses textual and structural content-based analysis based on a violent keyword dictionary. The paper focuses on the keyword dictionary preparation, and presents a comparative study of different data mining techniques to block violent content web pages. Findings - The solution presented in this paper showed its effectiveness by scoring a 89 per cent classification accuracy rate on its test data set. Research limitations/implications - Many future work directions can be considered. This paper analyzed only the web page, and an additional analysis of the visual content can be one of the directions of future work. Future research is underway to develop effective filtering tools for other types of harmful web pages, such as racist, etc. Originality/value - The paper's major contributions are first, the study and comparison of several decision tree building algorithms to build a violent web classifier based on a textual and structural content-based analysis for improving web filtering. Second, showing laborious dictionary building by finding automatically discriminative indicative keywords.

To satisfy the requirement of embedded video encoder in various scenarios, an embedded multi-channel video coding system based on multimedia processor-DM642 DSP is designed in this paper. For real-time application requirement, we optimize the encoder at three levels: Firstly, at algorithm level, develop some fast algorithm fitting for LISP;secondly, at system level, adjust the architecture of encoder and optimization data transfer with EDMA;thirdly, at code level, use linear assembly for key code. Experimental results show that the embedded video encoder can compress four channel CIF video data real-time.

作者： Jinyoung Moon Jungtae Kim Jongyoul Park Euihyun Paik U-Computing Research Group Electronics and Telecommunications Research Institute South Korea

An IPTV system that transmits multimedia contents through the IP network needs to adopt a conditional access system allowing the only entitled subscribers to view the premium content as other pay-TV systems do. Although several standard specifications have been published for interoperable models of conditional access systems, the proposed models are based on the unidirectional or restricted bidirectional broadcasting network and do not utilize the characteristics of the IP network. However, software download scheme through the bidirectional IP network enables it to change existing conditional access systems in a secure way. This paper introduces an interoperable conditional access system that can update any cryptographic software provided by different conditional access system vendors through downloading and executing dynamically the downloaded conditional access software only if the software follows the pre-defined interfaces.

IEEE International Conference on multimedia and Expo (ICME)

作者： Alberto Messina Maurizio Montagnuolo RAI Radiotelevisione Italiana Centre for Research and Technological Innovation Torino Italy Department of Computer Science University of Turin Torino Italy

The quantity of multimedia content available either through the traditional distribution channels, such as broadcast television, or through new platforms like the Internet, is continuously increasing. Tools for user-oriented access to desired information are thus needed. In this paper, we illustrate a novel fuzzy multimedia mining technique for genre characterisation, aimed at overcoming limitations of conventional crisp classification systems. Effective results in genre classification and characterisation are presented based on the extraction of structural and cognitive properties of the content.

The huge amount of video content and the increasing rate in which new content is being created makes video summarization a necessary tool for the efficient access and management of video repositories. Nevertheless, the huge amount of data and the complexity of current techniques make the implantation of the summarization systems a difficult or non practical task. This paper presents current advances in the development of a novel algorithm for on-line video summarization, which can be easily used also as a video retrieval tool, aimed to combine summarization quality with high computational efficiency providing a system that can be practical for both commercial and home environments.

Peer-to-peer service-oriented community coordinated multimedia (SCCM) is envisioned as a novel paradigm in which the user consumes multiple media through requesting multimedia-intensive Web services via diversity display devices, converged networks, and heterogeneous platforms within a virtual, open and collaborative community. In this paper, a generic P2P SCCM scenario is created and examined first. A SCCM model is designed with the adoption of the service orientation approach and principles. A tunneled hierarchical P2P model is designed and its performance is analyzed for improving service lookup and session setup. A preliminary SCCM prototype is developed with the design of content annotation service.

The explosive increasing amount of multimedia content to be offered in the Internet and the heterogeneity of the underlying networking technologies demand the provision of new QoS-enabled mechanisms and architecture to efficiently control, manage and monitor the networks. This paper first briefly introduces a complex system for multimedia content generation, transport and consumption, over heterogeneous network environment. This is developed in ENTHRONE I and ii projects, where a central concept and subsystem is the ENTHRONE integrated management supervisor (EIMS). Then, the focus of the paper is to present a novel service oriented monitoring framework as an essential part of the EIMS. The proposed QoS monitoring system aims at providing service performance verification with respect to the QoS guarantees specified in contractual agreements between providers and users. This is achieved by not only monitoring services inside wired and wireless access/core networks but also at the customer side. The presented system also provides monitoring information to service providers for providing quantified QoS-based services and service assurance and to network providers for managing network resources.

This paper describes an integrated system for the acquisition, automatic annotation and Web publication of television broadcast news programmes named ANTS (automatic newscast transcription system). The system consists of several analysis components integrated in a unified architecture. Users have the possibility to access a large daily-growing database of news stories from the main national channels, all identified, categorised and published in a fully automatic way. The system identifies story boundaries, extracts texts from spoken content, classifies stories by subject and links external relevant information coming from the Web. Performances of the system have been evaluated in a real-life scenario, by providing an instance of the system to a panel of professional users inside RAI. The strength of the approach behind ANTS consists in the ability to integrate several heterogeneous analysis components in a performant and ready-for-production environment, capable of elaborating many hours of material per day without significant service drops and with sufficiently good accuracy for industrial employment in large broadcasting facilities.
