Proceedings of INET'97, Kuala Lumpur, Malaysia, June 1997.

The paper summarizes recent technical developments in second-generation multicast audio tools (packet loss protection and repair, improved scheduling and cross media synchronisation) and the resulting improvements in terms of performance and usability. More sophisticated applications of Internet multimedia conferencing will, however, require further improvements in terms of both reliability and quality. We outline a number of technical solutions (improved redundancy and repair, higher-quality audio, heterogeneous distribution and improved acoustic effects) required to achieve these improvements which should therefore be incorporated into the next generation of multicast audio tools.
