Module overview

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.

Module aims

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.

Module content

Topics will include 2D and 3D audio-visual content capture, compression, transmission, adaptation, media quality evaluation, and users’ experience. Indicative content includes the following.

 

Part A – Audio processing

[1-2]     Characteristics of speech and audio signals, and audio processing chain.

[3-4]     Principles of audio capture and coding methods. Need for source compression. Definition of quantisation. Scalar and vector quantisation.

[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.

[15]      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.

[15]      Perceptual video quality assessment

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)

Assessment Strategy

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
