Course detail

Video and Multimedia Technology

FEKT-LVDKAcad. year: 2018/2019

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.
