AUDIO AND VIDEO PROCESSING - 2021/2
Module code: EEE3042
In light of the Covid-19 pandemic the University has revised its courses to incorporate the ‘Hybrid Learning Experience’ in a departure from previous academic years and previously published information. The University has changed the delivery (and in some cases the content) of its programmes. Further information on the general principles of hybrid learning can be found at: Hybrid learning experience | University of Surrey.
We have updated key module information regarding the pattern of assessment and overall student workload to inform student module choices. We are currently working on bringing remaining published information up to date to reflect current practice in time for the start of the academic year 2021/22.
This means that some information within the programme and module catalogue will be subject to change. Current students are invited to contact their Programme Leader or Academic Hive with any questions relating to the information available.
Expected prior learning: Mathematics equivalent to Year 2 of EEE Programmes.
Module purpose: Using lectures and examples, this module will provide the fundamental concepts needed to understand the operation of modern media processing and transmission systems delivering high quality audio-visual content.

[5-6] Probability density function, auto-correlation, cross-correlation, stationarity etc.
[7-9] Fundamental methods of speech processing. Voiced and unvoiced speech. Effects of windowing. Short and long term modelling of speech.
[10-12] Simple coding methods (PCM, APCM, ADPCM). Analysis and Synthesis coding methods. Analysis by synthesis coding methods. Harmonic coding.
[13-14] Audio reproduction formats and coding technologies, and spatial audio and 3D audio systems. File formats and standards.
 Perceptual evaluation of audio quality
Part B – Video processing
[1-2] Introduction to 2D-3D video applications and systems
[3-5] Video capture and coding principles. Image and video formats. Spatial and temporal redundancy. DCT. Motion estimation and compensation. Coding complexity. RD optimisation.
[6-9] Networked video concepts: processing, transmission/communications, and rendering.
[10-12] Media adaptation concepts: adaptation decision and content adaptation
[13-14] Introduction to 3D video compression. Depth perception cues. 3D video signal formats. 3D video compression approaches.

Alternative assessment: Not applicable: students failing a unit of assessment resit the assessment in its original format.
The assessment strategy for this module is designed to provide students with the opportunity to demonstrate the level of achievement made towards reaching the expected learning outcomes. Thus, a closed-book written examination has been designed that will assess the knowledge and assimilation of the necessary definitions and terminology, concepts and theory of 2D and 3D audio-visual content capture, compression, transmission, adaptation, media quality evaluation, and users’ experience. The examination also aims to assess the students’ ability to analyse common media processing problems and apply necessary solutions in accordance with their understanding of how media processing can address those challenges and limitations that can be faced in real-world situations.
Thus, the summative assessment for this module consists of the following.
2-hour, closed-book written examination
These deadlines are indicative. For confirmation of exact date and time, please check the Departmental assessment calendar issued to you.
Formative assessment and feedback
For the module, students will receive formative assessment/feedback in the following ways.
During lectures, by question and answer sessions
During revision & tutorial classes
By means of unassessed tutorial problem sheets
- Provide students with a basic understanding of the media signal processing systems that are ubiquitous in our modern age.
- Introduce them to the essential characteristics of the signals, their capturing, encoding, transmission and assessment of their perceived quality.

|002||Identify the processing, transmission and rendering stages of networked content distribution.||KCT|
|003||Develop appreciation of practical implementation issues related to signal compression for communication applications||CT|
|004||Construct knowledge on important features of different compression standards and identify their future requirements for new applications||KC|
|005||Describe and discuss the principles of media adaptation through the interaction between system capability and user experience.||KC|
|006||Learn and appreciate the differences of the assessment methods for perceived audio and video quality||KCT|

P - Professional/Practical skills
Methods of Teaching / Learning
The learning and teaching strategy is designed to achieve the following aims.
Directive learning through classroom teaching
Tutorial to enable students to check and clarify their understanding of the material
Learning and teaching methods include the following.
Lectures (3-hour lectures per week x 10 weeks)
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
