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. … For more content click the Read More button below.

Learning outcomes

On successful completion of 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.

Assessment summary

Continuous assessment: 40%

Final assessment: 60%

This unit contains hurdle requirements that you must achieve to be able to pass the unit. You are required to achieve at least 45% in the total continuous assessment component and at least 45% in the final assessment component. The consequence of not achieving a hurdle requirement is a fail grade (NH) and a maximum mark of 45 for the unit.
