Synopsis:

This course is the introduction to multimedia technology (audio and video). It overviews sound and picture acquisition, signal processing, transmission and distribution, recording and reproduction including physiology of hearing and vision. It provides fundamental information for understanding the main principles for system solutions in the field.

Requirements:

Knowledge of fundamentals from mathematics and physics.

Syllabus of lectures:

1. Physiology and anatomy of eye, psychovisual aspects of vision

2. Physiology of hearing, psychoacoustical aspects of vision

3. Image information preprocessing techniques

4. Electroacoustic transducers

5. Source coding of sound

6. Sound processing and recording

7. Sensing and reproduction of image, 3D reproduction

8. Fundamentals of room acoustics

9. Sound acquisition and reinforcement

10. Source coding of image information

11. Video transmission systems, television, IPTV

12. Basic measurements in acoustics

13. Applied image technology, video recording

14. Digital photography, desktop polygraphy, holography

Syllabus of tutorials:

1. Physiology of vision - determination of basic parameters of visual sensing

2. Multimedia signals - measurement on typical interfaces (e.g. SCART, HDMI)

3. Basic properties of analog and digital color TV systems

4. Image compression - computer simulation, subjective evaluation

5. Digital photo camera - measurement of parameters, High Dynamic Range Imaging (HDR), white balance

6. Image displays - measurement of basic parameters, electro-optical transfer function
