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
Development of multiple media documents
Development of documents in multiple media involves activities in three different
fields, the technical, the discoursive and the procedural. The major development problems of
artifact complexity, cognitive processes, design basis and working context are located where these
fields overlap. Pending the emergence of a unified approach to design, any method must allow for
development at the three levels of discourse structure, media disposition and composition, and
presentation. Related work concerned with generalised discourse structures, structured
documents, production methods for existing multiple media artifacts, and hypertext design offer
some partial forms of assistance at different levels. Desirable characteristics of a multimedia
design method will include three phases of production, a variety of possible actions with media
elements, an underlying discoursive structure, and explicit comparates for review
An Export Architecture for a Multimedia Authoring Environment
In this paper, we propose an export architecture that provides a clear
separation of authoring services from publication services. We illustrate this
architecture with the LimSee3 authoring tool and several standard publication
formats: Timesheets, SMIL, and XHTML
An MPEG-7 scheme for semantic content modelling and filtering of digital video
Abstract Part 5 of the MPEG-7 standard specifies Multimedia Description Schemes (MDS); that is, the format multimedia content models should conform to in order to ensure interoperability across multiple platforms and applications. However, the standard does not specify how the content or the associated model may be filtered. This paper proposes an MPEG-7 scheme which can be deployed for digital video content modelling and filtering. The proposed scheme, COSMOS-7, produces rich and multi-faceted semantic content models and supports a content-based filtering approach that only analyses content relating directly to the preferred content requirements of the user. We present details of the scheme, front-end systems used for content modelling and filtering and experiences with a number of users
Integrated content presentation for multilingual and multimedia information access
For multilingual and multimedia information retrieval from
multiple potentially distributed collections generating the
output in the form of standard ranked lists may often mean
that a user has to explore the contents of many lists before
finding sufficient relevant or linguistically accessible material to satisfy their information need. In some situations delivering an integrated multilingual multimedia presentation could enable the user to explore a topic allowing them to select from among a range of available content based on suitably chosen displayed metadata. A presentation of this type has similarities with the outputs of existing adaptive hypermedia systems. However, such systems are generated based on “closed” content with sophisticated user and domain models. Extending them to “open” domain information retrieval applications would raise many issues. We present an outline exploration of what will form a challenging new direction for research in multilingual information access
Modelling Reactive Multimedia: Design and Authoring
Multimedia document authoring is a multifaceted activity, and authoring tools tend to concentrate on a restricted set of the activities involved in the creation of a multimedia artifact. In particular, a distinction may be drawn between the design and the implementation of a multimedia artifact.
This paper presents a comparison of three different authoring paradigms, based on the common case study of a simple interactive animation. We present details of its implementation using the three different authoring tools, MCF, Fran and SMIL 2.0, and we discuss the conclusions that may be drawn from our comparison of the three approaches
