Digital television is a new and interesting platform for developing multimedia services. The MELISA platform aims at cross-media broadcasting over digital television and 3G mobile networks. The platform provides presentation of interactive video content, advertisement and gaming. The devices targeted by these services are Set-Top Boxes and Portable Digital Assistants. A new service, in combinat...

This paper addresses the dual problem of audio coding for compression and retrieval. Because of the sheer volume of multimedia data, much research effort has focused on coding techniques for the compression of this data. However, being able to store large amounts of data in a compact fashion has limited application if there is no meaningful way to access and interact with them. Traditionally, t...

Digital broadcasting enables interactive TV, which presents new challenges for interactive content creation. Besides the technology for streaming and viewing, tools and systems are under development that extend traditional TV studios with virtual set environments. This presentation reviews current technology and describes the requirements for such systems. Interoperability over the production, ...

CindyJS is a framework for creating interactive (mathematical) content for the web. The plugin CindyGL extends this framework and leverages WebGL for parallelized computations. CindyGL provides access to the GPU fragment shader for CindyJS. Among other tasks, the plugin CindyGL is used for real-time colorplots. We introduce the main principles, concepts and application of CindyGL and describe t...

Advances in hardware performance, network bandwidth and audio compression have made possible the creation of large personal digital music collections. Although, there is a significant body of work in image and video browsing, there has been little work that directly addresses the problem of audio and especially music browsing. In this paper, Musescape, a prototype music browsing system is descr...

In this paper we present a framework for eRicient representation, access, and manipulation of video data. Our approach is based on decomposing video information into its spatial (appearance), temporal (dynamics), geometric components. This derived information is organized into data representations that support non-linear browsing and efficient indexing to provide rapid access directly to the in...

Internet-based interactive TV is an emerging field that is affected by advances in various research areas including communication, interactivity, network efficiency, content management and aesthetics. Despite constantly reducing costs in the area of broadcast infrastructure development, this new medium has yet to claim its market position and recognition. Various reasons may be identified for t...

This work presents the development of innovative content for a low-cost Interactive Television service designed to adapt in order to cover varying content presentation and interaction requirements: from standard streamed content to new-media artwork. In this process, content, system and user complexities are introduced that need to be resolved before artwork with different requirements may be s...
