Overview
Content: In the lecture »Nachrichtenübertragung«, computer networks have been described from a system theoretical point of view. In this lecture we will use the Internet to realize multimedia applications. We start with an introduction to the properties of the human perception mechanism. Then, source coding for audio, images and video will be explained and the requirements for the transport of realtime data will be defined. Afterwards, we intoduce the basic mechanisms of the network and transport layer of the Internet. After demonstrating some example multimedia applications, we will introduce some more complex architectures for the support of media streaming with QoS (Quality-of-Service). |
