GZ05: Multimedia Systems


Lecturer: Mark Handley

Aims: to describe the ways in which multimedia information is captured, processed, and rendered, to introduce multimedia quality of service (QoS) and to compare subjective and objective methods of assessing user satisfaction, to discuss the ways in which multimedia data is transmitted across networks, and to discuss privacy and copyright issues in the context of multimedia.

Learning Outcomes: The ability to: describe different realisations of multimedia tools and the way in which they are used; analyse the structure of the tools in the light of low-level constraints imposed by the adoption of various QoS schemes (ie bottom up approach); analyse the effects of scale and use on both presentation and lower-level requirements (ie top down approach); state the properties of different media streams; compare and contrast different network protocols and to describe mechanisms for providing QoS guarantees in the network.
