There's a gap in consumer communications on how networks, devices, and services handle and identify space & time in media resources in the Web. W3C's Media Fragments URI specification, which we edited and contributed to over the last couple of years, not only bridges this gap by homogeneously opening up time-related media to the Internet crowd, but also makes time-related annotation feasible for...
The current multimedia landscape is characterized by a significant heterogeneity in terms of coding and delivery formats, usage environments, and user preferences. This paper introduces a transparent multimedia content adaptation and delivery approach, i.e., model-driven content adaptation and delivery. It is based on a model that takes into account the structural metadata, semantic metadata, and...
In this demonstration, we present NinSuna, a fully integrated multimedia content adaptation platform based on Semantic Web technologies. Moreover, we show how NinSuna can be used as a server-side implementation of W3C Media Fragment URIs, which enables addressing media fragments on the Web using URIs.
Recent advances in Web services have made it practical to provide communication Web services to enable communication through SOA and package communication capability as services. This paper provides an appropriate implementation to deliver the multimedia conferencing communication components as Web services in order to be used simply by Web service clients in converged applications.
Changes in legislation, an emphasis on widening participation and the increasing reliance on online techniques for learning and teaching have contributed to improved opportunities for students with disabilities. The need to cater for the needs and preferences of the individual learner is presenting significant challenges for the learning designer. This research suggests a solution that is based on...
Video adaptation has been introduction to tailor the same video to different derived user contexts to allow end users with different access network, client device and user profiles to access the same information source. Therefore, there is a need for the increase of automated auditing and intelligent reporting mechanisms for the download digital contents. This paper presents a proposed architecture...
ldquoAccess to information at any time, pervasive and with any device's typerdquo is a public demand. The problem, however, is to approach multimedia terminals with limited capacity and with different characteristics. In this heterogeneous environment, each entity or group of entities has its own functional / non-functional strongly influencing possible communications. The aim of this article is on...
This paper introduces a novel framework for implicit media content annotation by putting the user in the loop of the annotation process. In particular, a ser of visual features are extracted to describe the visual properties of the media content. Then, as the user plays with the content by downloading a set of media data, a mechanisms associates the textual user's queries with the visual metadata...
This article proposes an architecture that adapts multimedia flows to the context of the participants in communication in peer-to-peer systems. This architecture allows a pair to play several roles (pair adaptation, Proxy or communicating), the adaptation peer researches adapters, compose them, if it is necessary to have interfaces to adapt, to realize the complex adaptation operations and send them...
People using mobile devices for studying multimedia based educational content are often on the move and thus rely solely on their device battery power supply. When battery power runs low, they have to stop their activities, significantly reducing their learning outcomes and their satisfaction. This paper proposes a solution to perform the personalisation of the multimedia educational content, based...
The summarization of a multimedia document is a challenge that requires the summarization of media elements combined into a document but also relies on an appropriate adaptation of its presentation. In this paper, we present a scalable multimedia model that structures the multimedia scene into incremental Spatial, Temporal and Interactive layers and progressively provides presentation details. Our...
This paper presents the ongoing PhD work in the cross-domain area of P2P networking and advanced multimedia search methods. The author identifies and solves the problems encountered during the application of Query by Example search technique in structured and unstructured P2P overlays. A set of benchmarking methods as well as the results of large scale user tests are presented.
With fast development of media industry in our country in recent years, the demand for media talents is increasing and the model for talent training in the sector of news and communication has been transformed. The training of talents in this field needs to follow the development trend of domestic press industry. So attentions should be paid to changes in development in this industry so as to establish...
In this paper, based on the media adaptation framework and relations among entities in MPEG-21 DIA, two mixed-variable constrained optimization models are proposed, which unify current researches in media adaptation and can be solved by the direct searches. An overview on our work in media adaptation such as rate adaptation of MPEG-4 FGS video, video objects adaptation, etc., are given. Open issues...
Recent research on the learning process has shown that students tend to learn in different ways and that they prefer to use different teaching resources as well. Many researchers agree on the fact that learning materials shouldnpsilat just reflect of the teacherpsilas style, but should be designed for all kinds of students and all kind of learning styles. Even though they agree on the importance of...
The development of an open architecture for multimedia data integration and visualization in template based distributed applications is a challenge for the scientific researches. Because of characteristics of multimedia data, their management and querying techniques are unlike than those of traditional data. We can increase the potential use of multimedia data across various applications by storing...
Computing technology is radically changing the manner in which we work and communicate with computers. ubiquitous virtual reality (U-VR) has been researched in order to apply the concept of virtual reality and its technology into ubiquitous computing. In this paper, we analyze past research on ubiquitous virtual reality and find future research direction.
A new watermarking-embedding scheme is proposed to improve the detector performance. The embedder employs the media to control both the fidelity (using a visual model) and the detectability (using a feedback of the watermark detector). Media-content dependent watermark modulation can effectively resist copy attack and removal attack. Experimental results show that the proposed scheme has a distinguished...
