Picture Quality Analysis in Digital Television Systems
Bednarz, Robin ; Slanina, Martin (referee) ; Kratochvíl, Tomáš (advisor)
Diploma thesis deals with the analysis of quality in digital television systems and contains theoretical description of subjective and objective assessment of quality picture methods. The thesis contains short-term and long-term analysis of quality picture of terrestrial television DVB-T. Measurements and experimentations were carried out with the help of Rohde&Schwarz DVQ analyzer of picture quality and software MPEG-2 Quality Monitor and MPEG-2 Elementary stream analyzer.

Measurement of quality and errors of digital video in MPEG-2 TS at DVB-T reception
Kadlček, Jiří ; Kratochvíl, Tomáš (referee) ; Polák, Ladislav (advisor)
This bachelor’s thesis describes structure of the transport stream MPEG-2 TS of the DVB-T standard and subjective and objective measuring methods of the video quality. The work also includes the description of the measurement devices and software Quality Analyzer R&S DVQ, measuring decoder ¸ DVMD, MPEG-2 Realtime Monitor, MPEG-2 Quality Monitor, which were used for the measuring the video quality and errors of the MPEG-2 TS in DVB-T. In the next part the work deals with the measurement and analysis of errors and quality of digital video stream in MPEG-2 TS. The obtained results from the measurement are presented in tables and graphically evaluated. In this work a twentyfour hour measurements of errors and quality of digital video stream in MPEG-2 TS were made. The obtained results from these measurements are evaluated and discussed. Finally, a new laboratoy work for the simultaneously measurement of the errors in video stream and video quality of the MPEG-2 TS stream was proposed.
