Video and Multimedia Technology
FEKT-MVDKAcad. year: 2015/2016
Students become familiar with the fundametals of mathematical description of color lights and its use in creation of analog and digital video signals. The course continues by explanation of the principle of image scanning devices and displays, description of the format and properties of different analog and digital intergaces. Emphasis is put on explanation of the principle of source codecs and their practical application. Student acquire knowledge of the methods applicable to measurement of video quality.
Learning outcomes of the course unit
The graduate is able to:
- explain the representation of color lights in various color spaces and compute color coordinates in color mixing,
- describe the properties and the generation of video signal,
- explain the priciple of operation in image sensors of different types and different displays,
- explain and apply the tools of image, video and audio source codecs,
- use the appropriate interfaces and signal formats for interconnecting multimedia devices,
- analyze properties of a given multimedia system.
Students registering for the course should be able to explain the basic principles of digital signal processing (sampling, quantization, coding) and use the fundamental mathematical apparatus of derivation and integration. Generally, the knowledge of the Bachelor's degree level is required.
