Description

We are a research group at the Department of Scientific Computing, Paris Lodron University of Salzburg, Austria. Our current main areas of interest are satellite communications, DVB/MHP, intelligent caching, and IP multicast work. 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.
