Internet Protocol Television (IPTV) systems are a rapidly growing converged network service. These systems replace the traditional “set-top box”, receiving broadcast or cable television, with a networked IP-centric device, to which video is streamed live or on demand. The user experience initially follows that of traditional television, but it is expected that additional interactive services will be offered over time, as the potential of the underlying converged network architecture is exploited. Key to this, however, is ensuring the television service provided matches – or exceeds – that of traditional broadcast television. Converged networks suffer from different problems than do pure data networks and dedicated real-time transmission networks, so there is a need for new algorithms and protocol mechanisms to monitor reception quality and diagnose network problems. This project aims to develop such new algorithms and protocols.
Welcome to Stephen Strowes, who starts work as a new research student under my supervision today. Stephen is an EPSRC-funded student, who will be working on alternative network architectures.
