Presentation Services in MADEUS: an Authoring Environment for Multimedia Documents

The recent advances in multimedia systems, together with the advent of high speed networks, paved the way to a new generation of applications. In particular, authoring environments have found in multimedia the means of increasing the richness of information contained in electronic documents. One of the goals of the Opera team is designing an authoring environment for multimedia documents, called MADEUS, which meets the following requirements: a high level of expressiveness for both spatial and temporal dimensions; a user-friendly interface allowing highly interactive design process, scriptless and structured-based editing and automatic production of spatial and temporal layout; the portability and cross-platform interchange of multimedia documents. To achieve this research goal we first focus on finding a good representation of time for multimedia documents. This representation is required to capture the temporal dimension of media objects like video, audio, etc. and is also used to temporally organize objects with respect to each other. Time representation is clearly the main difference between multimedia authoring environment and traditional editing environments. We present in this paper our first investigational results in our experimental authoring environment MADEUS. A large part of these results are based on the experience acquired in implementing the MADEUS prototype

Authoring Environment for Interactive Multimedia Documents

In this paper, we make an analysis of the main requirements needed for building an authoring environement for interactive multimedia documents. These requirements are of different nature as they are related to a considerable number of computer science fields. Then, we present our contribution to meet these requirements. The particularity of our project is to consider the problem of multimedia authoring as a whole and to develop a real running application to validate our theoretical results. 1 Introduction The recent advances in multimedia systems, together with the advent of high speed networks, have paved the way to a new generation of applications. In particular, authoring environments have found in multimedia the means of increasing the richness of information contained in electronic documents. Multimedia documents compose in time and space different types of elements like video, audio, still-picture, text, synthesized image, etc. Interactive multimedia documents aim at transformin..

Time Representation and Management in MADEUS: an authoring environment for multimedia documents

In this paper, we present the currently achieved results of our research goal: building an easy to use and powerful multimedia documents authoring environment, which provides high level of expressiveness and open document format. These results are concerned with both the time representation and the time management in our authoring system Madeus. In the first part of the paper, we describe the requirements that must be provided by a time representation of multimedia documents, the choice we made and a comparison with other existing approaches. In the second part, we describe the presentation layer of our system, and how it handles services such as dynamic formatting, Temporal Access Control operations and hyperlinks. 1 INTRODUCTION One of the goals of the Opera team is designing an authoring environment for multimedia documents, called MADEUS, which meets the following requirements: a high level of expressiveness for both spatial and temporal dimensions; a user-friendly interface allow..

Dealing With Uncertain Durations in Synchronized

In this paper, we discuss the effect of the uncertainty in the duration of some multimedia objects on the qualityofthe presentation of multimedia scenarios. This uncertainty can be due to external factors such as the access delay over internet or the user interaction. An uncertain duration is often followed bya period of desynchronization during which the presentation deviates from the desired scenario. To solve this problem, we present in this paper a solution that integrates two complementary approaches which reduce the desynchronization and limit its propagation in the rest of the presentation. These approaches are non-blocking and use the flexibility in the duration of multimedia objects in order to resynchronize the presentation as rapidly as possible

A Survey on Mobile Crowd-Sensing and Its Applications in the IoT Era

Mobile crowd-sensing (MCS) is a new sensing paradigm that takes advantage of the extensive use of mobile phones that collect data efficiently and enable several significant applications. MCS paves the way to explore new monitoring applications in different fields such as social networks, lifestyle, healthcare, green applications, and intelligent transportation systems. Hence, MCS applications make use of sensing and wireless communication capabilities provided by billions of smart mobile devices, e.g., Android and iOS-based mobile devices. The aim of this paper is to identify and explore the new paradigm of MCS that is using smartphone for capturing and sharing the sensed data between many nodes. We discuss the main components of the infrastructure required to support the proposed framework. The existing and potential applications leveraging MCS are laid out. Furthermore, this paper discusses the current challenges facing the collection methodologies of the participants' data in task management. The recent issues in the MCS findings are reviewed as well as the opportunities and challenges in sensing methods are analyzed. Finally, open research issues and future challenges facing MCS are highlighted. - 2013 IEEE.This work was supported by the Qatar National Research Fund (a member of the Qatar Foundation) under Grant NPRP10-1205-160012.
