Digital Television and Radio Systems
FEKT-NDTVAcad. year: 2019/2020
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. The course continues by explanation of transmission principles in the individual transmission channels in satellite, cable and terrestrial digital video and audio broadcasting. Emphasis is put on explanation of principles of source coding, channel coding and modulation of video, audio and multimedia signals. Students acquire knowledge of the methods applicable to measurement individual standards for video and audio broadcasting.
Learning outcomes of the course unit
The graduate is able to:
- explain principles of sampling, quantization and coding of the video and audio signals,
- explain principles of source and channel coding and modulation for digital television and radio
- describe creation of transmission multiplex of video and audio for digital television and radio
- compare individual standards fro satellite, cable and terrestrial transmission of the digital television and radio
- characterize individual transmission channels for satellite, cable and terrestrial transmission of the digital television and radio
- analyze transmission parameters, transmission errors and quality of digital television and radio services
- measure parameters of the digital television and radio signals
Students registering for the course should be able to explain the basic principles of digital signal processing and data communication. Generally, the knowledge of the Bachelor's degree level is required.
