Comparison of modern television broadcast standards
Musil, Karel ; Vaněk, Jiří (advisor) ; Pavlík, Jan (referee)
This bachelor thesis is thematically focused on modern TV broadcast standards.
The emphasis is on the future development and possibilities. The first part provides
a comprehensive overview of the main topic addressed in terms of significant changes in
the second generation of digital technology. Including methods currently tested. The
greatest emphasis is placed on terrestrial broadcast due to the significance of this method in
the Czech Republic and currently ongoing transition to the second generation
of broadcasting. The second part focuses on the analysis of the actual developments, and
the not too distant future of the television broadcasting. The actual situation of the auction
of frequencies is introduced together with the estimation of the allocation of the spectrum.
Analyses the potential costs for the viewer and the signal provider, and compare the status
of broadcasting in Europe with the situation in the Czech Republic. Further, are defined
and analysed the possibilities of the next development of the terrestrial broadcasting.

ZigBee implementation for Automotive Industry
Zatloukal, Martin ; Maršálek, Roman (referee) ; Prokopec, Jan (advisor)
This bachelor’s thesis describes possibilities of usage of ZigBee communication protocol in automotive industry, transport and logistics. Thesis also deals with ways of practical implementation of ZigBee protocol including typical cases solutions, designing and realization of necessary electrotechnical devices and modules followed by compilation of control software and experimental measurements of these devices in real traffic flow. In the first part of thesis, there are some basic features and parameters of ZigBee reminded, followed by ways of ZigBee communicator usage description and adumbrating how to perform integration with existing practical systems. The second part is about analysis of ZigBee data system construction, communication system scheme design and pre-projection of block schemes of its particular cells. The third part concretizes requested functions and features of these cells and describes ways of its hardware realization. The fourth section describes controlling software design, connection and controll of functions using PC and additional programs, using of X-CTU software offered by MaxStream Company to set up XBee parameters and using of AVR Studio 4 offered by Atmel Company to set up ATmega16 processor. The last part is taken by completation of hardware and software, tests with a few of XBee chips and network nodes in laboratory conditions and examples from the real traffic range measurement.

Design and realization of wireless interface ODBII-XBee
Zatloukal, Martin ; Frýza, Tomáš (referee) ; Prokopec, Jan (advisor)
This master’s thesis describes possibilities of usage of ZigBee communication protocol and integrated circuit ELM 327 in problem of realization universal diagnostic device, running by OBDII communication standards, which can be used to monitor function of all car´s electronic systems. Thesis also deals with design and realization of necessary electro technical devices and modules followed by compilation of control software and experimental measurements of these devices in real traffic flow. In the first part of project, there are reminded some basic features and parameters of OBDII, followed by description of ways how to use OBDII and adumbrating how to realize universal diagnostic system. The analysis of ZigBee system focused on XBee circuits follows. Construction, ways of data transfer and possibilities of controlling are described. Integrated circuits produced by ELM Electronics Company are introduced and possibilities of usage ELM 327 are described as requested by main task. Second part talks about designing of electronic circuits of this system, assembling schematic diagram and designing sources for production of PCB. Physical realization of these circuits and its first start is also included. Thesis finishes by dealing with practical experiences and measurements using real vehicles. This part talks also about means to improve system by several software solutions to reach more effective functioning of created device.

Real-time protocol implementation
Procházka, Jan ; Skořepa, Michal (referee) ; Burget, Radim (advisor)
Thesis deals with multicast broadcasts, discusses the type of ASM and SSM. Also deals with the principle of RTP / RTCP protocol for large multicast groups, for example, broadcasting IPTV. It was created a model for simulating the behavior of the network load in a large number of receivers. The application was developed in Java and uses the recommendations of RFC3550. There are also analysed processes of communication, initialization, log out, the structure of the data packets and signaling packets. The system is designed that can simulate multicast network and obtain the estimated parameters of the operation, or can operate in real traffic, for example, as a third-party monitor. In both modes, the measurement was carried out model situations. The results of the measurements were then compared. Principle and system control was described in detail. Output measurements are graphically processed and included in the work.

Public service broadcasting in the European Union, organization and functioning: Study 5.309
Šmíd, Milan
Způsob organizace rozhlasového a televizního vysílání má v různých zemích různou podobu, podmíněnou politickými, ekonomickými, technologickými a kulturními specifikami daného státu. Při určité míře zjednodušení lze v této rozmanitosti vysledovat dva typy vysílání, které jsou výsledkem historického vývoje, a z něhož vyplývají také dva odlišné typy organizací (co do formy společnosti, financování, způsobu řízení, požadavků na programové výstupy atd.), jež toto vysílání provozují. Jedná se o rozhlasové a televizní organizace veřejného sektoru (státní nebo založené veřejným právem) a soukromého sektoru.

REGULATION OF RADIO AND TV BROADCASTING
Paroubková, Martina ; Soška, Milan (advisor) ; Gregárek, Matěj (referee)
An analysis of the state interventions into a broadcasting market will be the aim of this thesis. A state is in the most of countries represented by a special broadcasting market commission. In my thesis I will focus on the commission's behaviour. In the first part of my thesis I would like to consider a theoretical background, history and actual legislation of the electromagnetic spectrum regulation, particularly the legislation of both types of regulation -- structural and content regulation. Conclusions reached will be applied to the situation in the Czech Republic. The thesis should answer questions as whether the members of the commissions are objective, independent in their decision-making and behave within the defined legal frame. Acting of the Czech commission will be analyzed on the example of "Radio Wave affair". This radio station was taken from analog broadcast after the pressure from the Council of the Czech Radio.

Concept of in-college network improvement
Lorenc, Ján ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
This thesis is dealing with the description of properties for each loosy data compression format, their comparison in different encoding quality, internet radio streaming technology and its practical implementation. Main goal of this thesis is to make the further acquaintance of main encoding audio format theory, comparison of streaming commercial radios in Czech republic and also to expand the range of network services provided by University of Economics implementing streaming radio based on SHOUTcast technology.
