Communication Systems for Audio-Visual Applications


The integration of audiovisual information into distributed systems requires new mechanisms within the used communication systems. This is due to the time-criticality of continuous-media data such as audio and video Another impact is the typically large data volume of such data. Resource management mechanisms can be used to provide the necessary Quality of Service (QoS) to ensure that the timing requirements of multimedia applications are met. The goal of this lecture is to give an overview about the issues to be solved for the integration of audio-visual information in distributed computer systems and to present and explain methods for Qos provisioning. Besides principal considerations and notions about Qos we will study mechanisms of local computer systems, as they may be used in operating systems, and especially methods of distributed multimedia systems.
