Overview
This unit provides an understanding of the nature and limits of processing of media (image, video, audio) for telecommunications, storage, interpretation and analysis. It includes compression of multimedia from basic information theoretic concepts through to advanced video (e.g. MPEG), image (JPEG, JPEG2000) and audio (CELP, MP3, AAC, Dolby Digital) coding. XML-based metadata systems are used to illustrate concepts of content characterisation and discovery. The ability of modern network protocols to support media streaming is related directly to service requirements such as error and delay tolerance. Where media is intended for human consumption, the characteristics of human perception of image and sound determine minimum quality requirements, but also reveal limitations that can be exploited when compressing media data. Machine interpretation and analysis of multimedia is also investigated. Case studies in media analysis (e.g. Shazam), delivery (video on demand) and consumption (digital cinema) are used to illustrate the technologies investigated.

Learning outcomes
When you finish this unit, you should be able to:
- 1
Identify the limits of human visual and aural perception, and how they can be exploited for bit rate reduction.
- 2
Describe the structure of modern multimedia compression systems, and how they exploit the characteristics of both the media itself and human consumers of the media.
- 3
Explain how media can be characterised and described, including methods that allow similarities to be automatically identified (e.g. music matching services).
- 4
Compute the end-to-end delay performance of modern Internet protocols supporting media streaming, and relate this to service requirements for on-demand and communicative multimedia services.
- 5
Explain the methods of digital rights managements systems, including the role of encryption and key management, and the importance of such systems to enable high-value digital content retrieval services such as movies-on-demand.
- 6
As part of a team, research and investigate an area of interest beyond lecture material, involving software simulations and analysis of results.
