Course Details

Introduction

Nowadays a significant portion of the Internet traffic is due to audio/visual applications (VoIP, Youtube, IPTV). However, the used transport protocols (TCP, UDP/RTP) are inappropriate and lack means of optimised and application layer adapted content transport.

The course will introduce the requirements for media transport in the Internet, introduce proper channel models, calculate the channel capacity of those channels and derive a framework for optimised media transport. The focus is on the error coding in the transport layer, so that the results can be applied to any audio/visual application.

Besides giving an overview over recent specifications and standards (DVB, DLNA, ISMA) the course will introduce latest research results on media transport.

Prerequisites

Digital Transmission & Signal Processing (Telecommunications I) as well as Audio/visual Communications and Networks (Telecommunications II) are recommended for this course. Students with solid background in Computer Networks and Error Correction, however, are also encouraged to participate.
