A Distributed API for Searching Multimedia Databases

ACM SIGMOD Record, 1999

Facilitating information retrieval in the vastly growing realm of digital media has become increasingly difficult. DelaunapM seeks to assist all users in finding relevant information through an interactive interface that supports pre-and post-query refinement, and a customizable multimedia information display. This project leverages the strengths of visual query languages with a resourceful framework tlo provide users with a single intuitive interface. The interface and its supporting framework are described in this paper.

This paper describes the development of a multimedia information server that supports state-of-the-art distributed applications. This is achieved through techniques for efficient storage management of large objects, the provision of real-time data pumps controlled by scheduling mechanisms, multimedia object modelling and ODBMS functionality for the manipulation of objects. The system delivers MPEG-2 video and audio streams to multiple clients and supports browsing on the components of HTML documents and on MPEG-2 video sequences. The server functionality is exported as a proprietary application development interface in a sophisticated client subsystem. Current research focus is on content-based browsing and retrieval techniques as well as for the completion of the implementation of the DAVIC-compliant server functionality of the system.

The multimedia databases organisation and management needs various standardisation for simplifying their structure and access methods. They allow integrating different levels and different techniques of programming. The paper describes several aspects of Medical Centre Services organisation that offers various services via Internet standards. Several multimedia systems for training processes have been implemented in this package for network information content development and distribution.

Abstract: Managing the increasing growth of multimedia content still poses some problems. The challenge is to propose relevant information to the users among the large volume of information available. The main idea that drives our approach is to provide an open ...

While text indexing on the Web and corporate intranets has received considerable attention, indexing of multimedia documents in the same environments is still in its nascent stages. We have developed a system that allows us to index and serve multimedia documents over the Internet. The system has been in continuous operation since March 1998 within the company and has been tested extensively under heavy load conditions. In this paper we describe the design and implementation of the system and we present a user-model study indicating the usage patterns that we encountered during the system deployment. The main part of the paper presents the results of a detailed study that sheds light into the performance characteristics of the system components, identifies bottlenecks, and provides information to systems designers interested in delivering systems with good performance for this important class of applications. We find that the limiting factor for the three major subcomponents that co...

Universal Plug and Play (UPnP) is a widely accepted standard for automatically detecting devices and services in a local area network as well as for describing and controlling them. In order to deal with multimedia devices and especially content, in 2002 the UPnP-AV standard definition was released. It defines device and service descriptions for Media Servers and Renderers. Thereby, the Media Server's Content Directory Service allows an easy management and the exchange of metadata about the provided media data. Media content became browsable by semantic meta information about it.

Visual information, especially videos, plays an increasing role in our society for both work and entertainment as more sources become available to the user. Set-top boxes are poised to give home users access to videos that come not only from TV channels and personal recordings, but also from the Internet in the form of downloaded and streaming videos of various types. Current approaches such as Electronic Program Guides and video search engines search for video assets of one type or from one source. The capability to conveniently search through many types of video assets from a large number of video sources with easy-to-use user profiles cannot be found anywhere yet. VideoAnywhere has developed such a capability in the form of an extensible architecture as well as a specific implementation using the latest in Internet programming (Java, agents, XML, etc.) and applicable standards. It automatically extracts and manages an extensible set of metadata of major types of videos that can be queried using either attribute-based or keywordbased search. It also provides user profiling that can be combined with the query processing for filtering. A user-friendly interface provides management of all system functions and capabilities. VideoAnywhere can also be used as a video search engine for the Web, and a servlet-based version has also been implemented.

Nowadays, digital libraries are inherently dispersed over several peers of a steadily increasing network. Dedicated peers may provide specialized, computationally expensive services such as image similarity search. Usually, the peers of such a network are uncoordinated in the sense that their content and services are not linked together. Nevertheless, users expect to transparently access and modify all the (multimedia) content anytime from anywhere not only in an efficient and effective but also consistent way. To match these demands, future digital libraries require an infrastructure that combines various information technologies like (mobile) databases, service-oriented architectures, peer-to-peer and grid computing. In this paper, we sketch such an infrastructure and illustrate how an example digital library application can work atop it.

reeen! availability of low+cost powcrful workstations and res has caused a slaggering increase in the quantit)' and quality of digital data, which includes still images, video clips, and sound. 11le problcm of managing such a large volume of information has bccomc very important for researchers who need efficient and simple access 10 the data. In Ihis paper wc present a framework for managing the storage, analysis, and access of multimedia data. Wc address the problems of user access and data management via an extensible graph.ical user interface which is the front-end to a semantic objectoriented multimedia management tool. Wc present a new method for efficient content-based searching of image and video data, and we examine several proposed solutions to the problem of Internet access to large multimedia databascs. Résumé. L'apparition récente de stations de travail et de PC puissants à bon marché a entraîné une augmentation prodigieuse de la quantité et de la qualité des données sur support informatique, comprenant entre autres des images fixes ou des séquences sonores ou vidéo. Le problème de la gestion de tels volumes d'information est devenu particulièrement important pour les chercheurs, qui ont besoin d'un accès simple et efficace à ces données. Cet article propose un modèle de travail permettant de gérer la conservation, l'analyse et l'accessibilité des données multimédia. Nous discutons les problème de l'accès utilisateur et de la gestion des données via une interface graphique extensible, qui elle+même repose sur un outil de gestion multimédia sémantique et orienté objet. Nolis proposons une nouvelle méthode pour une recherche de contenu efi1cace sur des images et des données video, et nOlis examinons diverses solutions proposées au problème de l'accès via Internet à de larges bases de données lllultimédia.
