The theoretical aspects of modern digital television standards, methods and measuring instruments used in this industry, and the basic principles of constructing digital television transmission equipment are considered.

Course content:

Topic 1COFDM modulation. Basic principles (justification for the choice of radio signal parameters for NTTV, the use of ODFM for operation in multipath conditions, features of digital types of modulation, generation and demodulation of COFDM signals, ensuring their noise immunity). The principle of constructing single-frequency terrestrial digital television networks of DVB-T and DVB-T2 standards in the Republic of Belarus

Topic 2Terrestrial digital television broadcasting system DVB-T. Terrestrial digital television broadcasting system DVB-T2. Differences and innovations in relation to the DVB-T standard

Topic 3MPEG-2 transport stream structure. Measurement and analysis of MPEG-2 transport stream. Features of measuring parameters of channels with digital modulation. Measurements in DVB-T and DVB-T2 terrestrial digital television broadcasting systems

Topic 4Structure of digital television transmitters. Linear, nonlinear correction. Circuit solutions in the construction of power amplifiers for digital television transmitters. Main controlled parameters (using the example of PROMSVYAZ transmitters RTC-2000, RTC-1000M). Promising developments and further development of terrestrial digital television broadcasting systems
