Digital terrestrial television broadcasting DVB-T/H and DVB-T2
Pospíchal, Martin ; Ulovec,, Karel (referee) ; Kratochvíl, Tomáš (advisor)
Master's thesis compares the standard for digital terrestrial television broadcasting of the first generation DVB-T/H and the second generation DVB-T2 with particular emphasis on the modulator, a security channel interference, the signal from the transmitting environment itself and the modulation signal. The following description of specific models of transmission channels for fixed, portable and mobile reception of digital terrestrial signal. Comparison with the particular relates of the transmission parameters for different types of reception of digital terrestrial television with achieving efficiency and effectiveness of transmission at the level of laboratory measurements and computer simulation.

Digital television broadcasting according to standard DVB-H
Pospíchal, Martin ; Prokopec, Jan (referee) ; Kratochvíl, Tomáš (advisor)
The bachelor work deals with problems of digital broadcast based on the standard DVB-H. It contains of the theoretic part and than there is the experimental part. The theoretic part compares the standard DVB-T with DVB-H in the introduction. Then comes after the theoretic explanatinon of the source coding of the picture and the standard for the coding the sound, channel coding and the modulation of the signal. Then it describes a scheme for metering the norm of DVB-H composed of a laboratory qauqing apparatuses and its brief describtion. Then comes after the description of the several metered and biased parameters and its impression on the quality and level of the recieved signal. The experimental part deals with the metering of the several parameters, that contains the description of the laid metering constellation diagrams, tables of the measured values, graphics dependences and evaluation of the concrete metering. The metering deals with the influence of the amplitude of the screened signal, phasic error, suppression carrier, amplitude imbalance, convolution code, guard interval and with the using the several modulations on a bit error rate BER, modulation error rate MER (S/N), the quality and the level of the received signal for the several TV channels.
