Description
This research group comprises three labs.
Multimedia Signal Processing and Security Lab
Our current main areas of interest are image and video compression algorithms, image and video encryption, watermarking, visual data transmission, and methods for visual data integrity and authenticity. Our expertize includes:
- Wavelet-based image and video processing
- JPEG and JPEG 2000 compression and security
- MPEG and H.26X coding and security
- Multimedia security in general
- Reliable and secure multicast protocols
Funding is mainly FWF based.

Multimedia Communications Lab
Our main areas of interest include satellite communications, DVB/MHP, intelligent caching solutions, and IP multicast related work. Furthermore, we are participating in the FP6 IST Satellite Network of Excellence (SatNEX) project. For more information, please visit our website at http://www.network-research.org/.
Our expertise includes:
- Optimized protocols for satellite communications
- Digital Video Broadcast (DVB)-based gateway architectures
- Multimedia Home Platform (MHP) application and service development
- Reliable multicast transport protocols
- Multicast web caching technologies
- Multimedia and hypermedia applications
- Design of network communication hardware and software
- Traffic monitoring, measurement and analysis
The group operates two development laboratories with more than 50 PCs and Workstations running various Windows and Unix flavours.
A dedicated IP/DVB and MHP Test Center has been recently set up, interconnecting the IRT/MHP Playout Server with an IP/DVB encapsulator/multiplexer and several set-top boxes and PCs over three DVB transmission chains (DVB-S, -T, -C) in a local loop trial environment. Several analysers for TS/MPEG-2 level and MHP are available for monitoring and verification purposes.

Computational Geometry and Computer Graphics Lab
Our current main areas of interest are:
- Computational Geometry and Discrete Mathematics/Optimization
- Algorithms and Data Structures, Program Design,
- Computer-Aided (Geometric) Design and Manufacturing,
- Geographical Information Systems,
- Computer Graphics, Visual Computing and Virtual Reality.
