This diploma thesis deals with the design of the radio network for the track section Břeclav-Znojmo. Firstly, the theoretical knowledge about GSM-R, Radiolab and radio relay is described. The next part deals with the measurement of the already covered section of the track and the selection of a suitable propagation model. Radiolab is designed to cover several diffusion models. The model used for the final design of the network is chosen based on the comparison of the measurement results with the proposed coverage in Radiolab. The last part describes the provision of connectivity to individual base stations. Several connectivity options are compared.

This essay aims to analyse the form of two radio documentary shows and compare them to, what I mean are a traditional, Swedish radio documentary form. The radio shows are Radiolab distributedby National Public Radio and WNYC, Övernaturligt (supernatural) produced by TredjeStatsmakten Media AB and P3 Dokumentär (P3 Documentary) distributed by Sveriges Radio. Alarge part of the essay is dedicated to develop a method to analyse form in specific radio shows. Mymethod consists of two parts:1. A defining of sounds in a spreadsheet that map out the different sound elements over time.2. An analysis of the radio documentaries using the spreadsheet, text-analytic tools, rhetoric toolsand an holistic view of how different stories connect.My essay shows how these two radio documentary shows use so called layers and the changing ofroles between the presenter and the reporter to replicate a live show in closeness to the audience andin turn, how this may affect the presentation of their journalistic content. I also show how theseradio shows use illustrative and side stories to build up the main story of the show.

Master’s thesis is focused on SFN (Single Frequency Network) and MFN (Multi Frequency Network) networks design in digital television broadcasting based on DVB-T standard and digital radio broadcasting based on T-DAB standard. First part of the thesis is focused on the theoretical description of the MPEG-2 TS transmission, its propagation from transmitter across free space, to be decoded in the DVB-T receiver. In the second, practical part of the thesis, basic parameters of a software package for broadcast network design in RadioLab, RadioBase and Sítě SFN are introduced and the results are displayed on the digital terrain map and morphologic map. Within solution of this thesis was created signal coverage model of DVB-T digital transmitters in entire area of the Czech Republic, so called networks no. 1-4, according to its status in spring 2010, and its future expansion, which is known from TPP (Technical Plan of Conversion) document. At the conclusion of thesis there were made experiments with the modeling of transmitters’ radiated power, guard interval selection and location of DVB-T transmitters in the SFN network.
