Utilization of MHP platform in DVB-T
Janík, Lukáš ; Balík, Miroslav (referee) ; Kohoutek, Michal (advisor)
This bachelor‘s thesis solves the problem of digital television and set-top boxes, more precisely MHP platform and its use in DVB-T. In the first chapters I talk about analogue terrestrial broadcasting and necessity of transition to digital broadcasting. In addition, you can read about the necessity of the MHP platform implementation as the stable part of the DVB-T. I analyse this platform and describe the pros, cons and possibilities for its use at presen and in the future. I mention the different types of set-top boxes and their main manufacturers. I also describe an application development cycle, from writing the source code, despite testing in the development environment of IRT, respectively Osmosys, until loading to the real set-topbox. I also represent here the practical part of my bachelor‘s thesis, which was the development of chat client for the MHP platform and it allows two users to communicate in real time. This application I tested in the IRT and I uploaded it to the real set-top box. Next I analyze Java programming language, such as the appropriate development language for this platform. I mention the HAVi standard and its relevancy in usage of MHP platform.

Possibilities of increasing the throughput of optical fiber industrial networks
Čičmanský, Tomáš ; Münster, Petr (referee) ; Filka, Miloslav (advisor)
Diploma thesis deals with problems of industrial networks using optical fiber as the main transmission lines. The task of the diploma work is to study and summarize the issues of industrial networks as well as the ways to increase their transmission capacity. In telecommunications and computer networks are generally used multiplexes, thanks to which we are able to achieve the desired transmission capacity. Consequently, the following work deals with the selection of the adequate solutions using described multiplexes as well as other transmission methods. The aim of the diploma work is to compare various renovation techniques of an old industrial network. Using this network as an example the work should demonstrate the individual problems and their solutions while considering different types of methods used. Based on the price, the performance and the difficulty to install other devices and transmission media we are able to select the appropriate solution for optical link.

Spread spectrum modulator
Lejsková, Alena ; Kováč, Michal (referee) ; Maršálek, Roman (advisor)
This thesis deals with a method of spectrum-spreading of the data signals transmitted in the radio channel. There exist three different ways of spreading application, they uses pseudorandom sequences and also orthogonal sequences. In these systems we can find various kinds of modulations, one of them (Quadrature Phase Shift Keying) is shown at the end of the thesis. Spectrum spreading orthogonal multiplex OFDM is based on this method. The thesis wants to present the principle of the spectrum spreading method and the description of systems, transmitters and receivers that are using this method.

Design of Multiplex Optical Fibre Link
Krejča, Libor ; Křivánek, Vítězslav (referee) ; Kyselák, Martin (advisor)
In this thesis I consider problems of optical multiplexers, optical amplifiers and designing optical networks with this components. CWDM and DWDM are the most common used multiplexers today. I describe principles of realization multiplexers from basic level to realization in WDM networks. EDFA is also common used amplifier today and I describe his internal structure and how it works. Today, we can observe many realization of optical netwoks with Raman amplifiers, especially in long haul networks. Raman amplifier is characterized in brief. In next chapter I describe the design of optical communication systems and the main designing equations are explained. Then I used the equations for example of designing optical communication system with multiplexers, EDFAs and other components, which are needed for function of the system. In last chapter I explain mathematical model of signal propagation in optical fiber called nonlinear Schrodinger equation, which includes main optical effects in fiber like chromatic dispersion or Kerr effect. The simulation model and his numeric solution was designed including PMD effect, the simulation model is programmed in MATLAB.

Cinema services as a market of vertical and horizontal differenciated product
Jakoubek, Jakub ; Koubek, Ivo (advisor) ; Brožová, Dagmar (referee)
This bachelor thesis analyzes cinema market in the Czech Republic. Multiplexes are crushing their competition of regular cinemas in number of spectators and net revenues. The main aim of the thesis is to prove that product differentiation and distance between the competitors are more important than standard relationship: quantity demanded - supplied price. Based on the data from UFD, where can be found information about all cinemas and multiplexes from the years 2006 - 2014, I estimate models using econometric analysis, which examines the effects of the determinants on the cinema demand. The main focus is on distance to the nearest competitor and quality factor. Conclusions of the thesis confirm that vertical differentiation has the biggest effect on the number of spectators and on the other hand, distance to the nearest competitor is not able to explain the damage from a distance. It turns out that the price differential reflects qualitative differences and the distance between the cinemas.

What is the difference between determinants of ticket demand at an open air cinema and multiplex cinemas?
Knittelová, Tereza ; Lahvička, Jiří (advisor) ; Svoboda, Miroslav (referee)
This bachelor thesis identifies the determinants of the demand of an open air cinema. As a basis, data from the open air cinema Širák in the years 2010 -- 2013 has been used. It has been shown, that open air cinema's price elasticity of attendance demand is roughly unit elastic thus it maximizes its revenue from sold tickets. In comparison a multiplex cinema does not maximize its revenue from sold tickets and its price elasticity of attendance demand is inelastic. As a result of this thesis it has been found that visitors of an open air cinema are almost unaffected by movie genre in their decision to visit the open air cinema. However this is not the case for visitors of a multiplex. Visitors of either cinema prefer Czech movies over foreign ones. The attendance of the open air cinema is highly influenced by the weather.

Management of movie houses after 1989 in Prague 1 and 2
Smiková, Michaela ; Hanzlík, Jan (advisor) ; Hucková, Barbara (referee)
The Bachelor Thesis deals with destinies of the movie houses which were occured in urban districts Prague 1 and Prague 2. The theoretical part deals with the influence of historical events on the management of movie houses during the 20th century, from its beginning when the movie houses noticed progressive growth, til their decline after the 1989. The practical part focuses on current state of these movie houses. How the cinemas are prospering and what is the function of defunct cinemas today. The aim of this thesis is outline the historical course of sustainability of movie house management, mapping of the defunct movie houses in Prague 1 and 2 and analysis of current situation of the movie houses which still work.

Demand for cinemas - what determines the consumer behaviour?
Řeháková, Petra ; Mičúch, Marek (advisor) ; Kovanda, Lukáš (referee)
The main aim of this diploma thesis is to identify the determinants of behavior of demand for multiplexes in Prague. The main building material is the dataset of attendance and revenues evolution for individual movies distributed between years 2002 and 2011, always for the first four weeks from the premiere, provided by the Union of Film Distributors. The paper investigates consumer behavior on the movie market. The demand for movies is the dependent variable measured by the number of visitors in the corresponding weeks. The subject of analysis -- explanatory variable - is price, film rating (critics), genre, country of origin, character of time frame, frequency of screenings in a given week, format (2D/3D), length of movie, popularity of the actor/director, impact of movie series etc. The data are exposed to the regression according to which the significance of different variables is tested. The hypothesis about strong negative correlation of the price and quantity demanded is investigated based on the results, (Dewenter R., Westermann M., 2005) versus the hypothesis of weak sensitivity those two variables (Sangho Kim, 2009) against a more significant relationship of demand and other determinants. The influence of price on attendance has shown to be insignificant on the Prague movie market in the short term. A significant determinant impacting the attendance for a movie in the entire monitored period is the film rating, actor, length of movie, and number of screenings.
