Kvalita příjmu digitálního televizního satelitního vysílání

Abstract

In this dissertation are described reception possibilities of a digital video broadcasting. Spreading, processing and receiving of the digital satellite broadcasting are worked more detailed. The main objective of this thesis is to discover and describe the influence of the weather on the reception quality of the satellite broadcasting and influence of antennas deflection on reception parameters. For accurate measure of deflection was founded a method, depicted in chapter three as well as the other methods of measuring. The influence of deflection is analyzed separately for each type of parabolic antennas and for both types of polarization. Qualitative parameters of the reception are compared with meteorological data in time, which are taken from Czech Hydrometeorological Institute. Influences between the weather and reception parameters are described on the basis of thorough analyze. Summary and recommendations are presented at the end of this thesis.
