Enriching multimedia content description for broadcast environments: from a unified metadata model to a new generation of authoring tool

Abstract

In this paper, we propose a novel approach for authoring a diversity of multimedia resources (audio, video, text, images, etc). We introduce a prototype authoring tool (called M-Tool) relying on a metadata model that unifies MPEG-21 and TV-anytime descriptions to edit and enrich audiovisual contents with metadata. Additional innovative functionalities extending the M-Tool are also presented. This new generation of metadata authoring tools is designed and currently used for scenarios of TV and news broadcasting, and video on demand broadcasting in the framework of the IST Integrated European Project ENTHRONE.
