Multimedia applications require the handling of synchronization between media streams. We present tools for creating, editing and presenting synchronized multimedia objects. Specifying synchronization is supported by the graphical Synchronization Editor and execution of multimedia presentations is performed by the Synchronizer. Major topics cover requirements resulting from underlying distribut...

Multimedia authoring does not consist solely of the specification of the temporal and spatial layout of a document. Application specific concepts (e.g. for computer based training) or animation effects (e.g. moving media items) are often required by authors. Existing multimedia authoring tools support only one specific concept for the temporal specification, spatial specification and interactio...

The composition of interactive multimedia titles is a challenge for all advanced multimedia authoring tools. When non-interactive titles were specified by aligning the media items on a temporal axis such as time lines or tracks, now interactive multimedia titles require a non-linear temporal model. Thus, authoring becomes more complex, and the structure of a title is more difficult to visualize...

A common approach to experimental multimedia network applications is to structure a range of media tools as independent monolithic applications. In this approach, every change must be incorporated into the appropriate applications, requiring each to be entirely recompiled and then redistributed to users. To simplify this procedure, we decompose the tools into reusable and flexible components, m...

The development of the Semantic Web, the next-generation Web, greatly relies on the availability of ontologies and powerful annotation tools. However, there is a lack of ontology-based annotation tools for linguistic multimedia data. Existing tools either lack ontology support or provide limited support for multimedia. To fill the gap, we present an ontology-based linguistic multimedia annotati...

Building accurate knowledge of the identity, the geographic distribution and the evolution of living species is essential for a sustainable development of humanity as well as for biodiversity conservation. In this context, using multimedia identification tools is considered as one of the most promising solutions to help bridging the taxonomic gap. With the recent advances in digital devices/equ...

Over the last decade, a wide spectrum of (multimedia) content has become available to an increasing number of users who desire to access it through various devices and over heterogeneous networks. Interoperability is the key for enabling transparent and augmented use of (multimedia) content across a wide range of networks and devices. Standardization efforts within the Moving Picture Experts Gr...
