Course detail

Digital Broadcasting and Video Technology

FEKT-MPC-DVVAcad. year: 2020/2021

Students become familiar with fundamentals of sampling, quantization and coding of video and audio, then with compression and creation of transport stream and multiplexation in the digital video and audio broadcasting standards. Emphasis is put on explanation of the principle of source codecs and their practical application. The course continues by explanation of transmission principles in the individual transmission channels in satellite, cable and terrestrial digital video and audio broadcasting. Students acquire knowledge of the methods applicable to measurement of video quality and measurement of individual standards for video and audio broadcasting.
