Quality measurement of analog and digital terrestrial television broadcasting
Zach, Ondřej ; Polák, Ladislav (referee) ; Slanina, Martin (advisor)
This bachelor‘s thesis deals with the description of basic features of the analog and digital television broadcasting and suggestion of a method for objective video quality evaluation at both broadcasting types. The base of this thesis is description of picture broadcast technology in analog and digital form. Also principles of some video quality evaluation metrics are described. In this thesis, a method for video quality comparison is suggested, including a verifying of this method. According to this method, sequences at changing broadcasting conditions were recorded for both broadcasting types. The quality factors of these sequences were computed and on the basis of these factors, the analog and digital TV broadcasting were compared.

Twitter Connection with a TV Broadcast
Fiala, Marek ; Rychlý, Marek (referee) ; Burget, Radek (advisor)
This master thesis focuses on the possible connection between the digital television broadcasting DVB and the Twitter social network. The target platform is the Hybrid Broadcast Broadband TV platform, which combines television broadcasting with a data received from broadband. The created system is composed of a HbbTV application and a server, that connects the application with the Twitter and searchs for additional data about the current video content. Usage of the resulting solution in real television broadcasting could potentially increase the amound of tweets related to the television broadcasting, increase the knowledge about HbbTV technology and attrack young generation of viewers. All that can result into slight increased number of viewers.

Automatic Data Recording of Digital Satellite Broadcast
Řezníček, Ivo ; Matějka, Pavel (referee) ; Szőke, Igor (advisor)
This work aims at the creation of a~system of massive recording of multimedia data, especially speech data in various languages. The first issue is to find out high quality data source, the second is to build the system for managing and storing received data in the digital form. A digital satellite transmission is chosen as a signal source (DVB-S system). Main system features include recording of multiple streams in parallel, support of multiple cards, retrieving and storing of additional information (from Internet) and scheduling of recordings. The system will provide massive amounts of data for training of a language identification system.

Transmitting television signal via fiber optics
Abbasi, Farhad ; Vojtěch, Josef (referee) ; Münster, Petr (advisor)
Hlavním cílem této práce je teoretická analýza přenosového DVB TV signálu prostřednictvím optických vláken, analýza sítě CATV a modulační techniky pro její přenos. První částí této práce je zavedení šíření signálů v optických vláknech a pasivních součástech optických sítí, následované obecnými informacemi o digitálním rozhlasovém vysílání, sítí CATV a modulačním formátu pro jejich přenos. V druhé části, která se nazývá praktická část, vysvětluje výsledek měření, který se skládá ze srovnání různých měřicích parametrů, jako jsou "Power SIGNAL", "C / N", "Kanálový výkon" pro rozdílné délky optických vláken.

Error Analysis in Measurements on the MPEG-2 TS Digital TV Transmision
Chrobák, Jan ; Slanina, Martin (referee) ; Kratochvíl, Tomáš (advisor)
This essay shows up the monitoring and error measuring in transportation stream MPEG-2 TS during the digital TV broadcat recieving accordingly to the DVB standard. There are DVB definitions and standards for transportation stream transmition, decoding conditions and service informations chart described in the introduction of this essay. The measuring decoder R&S DVMD has been used for experimental measuring in the laboratory. This decoder enables long-time monitoring and automatized errors evaluation of particular priorities. The processed results of DVB-T multiplex 1 and 2 and DVB-S, paket CS link, TV broadcat recieving are the part of this essay as well.

SFN and MFN networks design in DVB-T
Dostal, Radek ; Láčík, Jaroslav (referee) ; Kratochvíl, Tomáš (advisor)
Bachelor’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. First part of the thesis is focused on the theoretical description of the MPEG-2 transport stream and basic parameters of broadcasting network, transmitters and transmission path. In practical part are introduced basic parameters of a software package for broadcast network design in RadioLab, RadioBase and Sítě SFN, and results displayed on the digital terrain map and morphologic map. Within solution of this thesis was created signal coverage model of digital transmitters in entire area of Czech Republic, so called networks no.1-4, according to its status in spring 2008. Next is focused on government order about convert from analog to digital video broadcasting terrestrial.

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.
