Multimedia modeling using MPEG-7 for authoring multimedia integration

Abstract

In this paper, we describe an approach to audiovisual data modeling for multimedia integration and synchronization. The approach chosen consists in using description tools from Multimedia Description Schemes of standard MPEG-7 to describe audiovisual contents and in integrating these description models into a multimedia integration and synchronization model close to SMIL. The resulting model provides relevant specification tools for the fine integration of multimedia fragments into multimedia presentations. An authoring environment illustrates the authoring features that can be obtained thanks to these integrated models.

A Laboratory for Prototyping and Testing Multimedia Presentations

“…30, Tran-Thuong et al integrate MPEG-7 tools for content modeling in a SMIL-like multimedia model, to make the authoring process easier. Mdefi provides three views: the timeline view for editing the temporal structure, the execution view to lay out media items in the user interface, and the hierarchical view, i.e., a tree view of the structure of the document.…”

“…With respect to a timeline approach 1,3,24,28,30 , a description based on graphs 14,21,34 , flow-charts 22 and virtual timelines 7 is more flexible, since it does not depend on the actual length of the media items. On the other hand, the timeline description is more intuitive, since it is not always easy to capture the real presentation evolution from an event based description like a graph.…”

COSMOS-7: Video-Oriented MPEG-7 Scheme for Modelling and Filtering of Semantic Content

“…The descriptions may also be viewed in an hierarchic tree-like structure. Mdefi [49] is an authoring tool for multimedia presentations that also enables the creation and editing of MPEG-7 descriptions. These descriptions are then integrated into a synchronisation model which is similar to SMIL (Synchronised Multimedia Integration Language).…”

Enriching Multimedia Content Description for Broadcast Environments: From a Unified Metadata Model to a New Generation of Authoring Tool

“…By providing a full and comprehensive description solution for multimedia contents, the MPEG-7 standard has emerged as the primary choice for mono-media approach in numerous authoring tools [RSK02,IBM02,TR03]. Conversely, there is almost no authoring tool relying on TV-Anytime.…”

“…Enikos [ENI05] [TR03] combines two models: the MPEG-7 standard and a SMIL-like multimedia model. MPEG-7 is used to describe audiovisual resources and the SMIL-like model to integrate these resources inside a complex multimedia presentation.…”
