Invisible watermarking of digital signals
Pacura, Dávid ; Horák, Karel (referee) ; Petyovský, Petr (advisor)
Cílem téhle práce je navrhnutí nových technik pro robustní neviditelné značení digitálních signálů. Nejdříve je prezentován současný stav tohoto odvětví a dostupné softwarové řešení. Poté následuje návrh několika algoritmů pro neviditelné značení, přičemž každý z nich je založen na jiném principu. Dále je připravena sada digitálních testovacích signálů společně s testovacím softwarem pro otestování navržených řešení a jejích porovnání s vybraným dostupným softwarem. Poté následuje srovnání naměřených výsledků, výkonu a jejích diskuze.

Multimedia Player for iOS
Singh, Kevin ; Číka, Petr (referee) ; Grabovský, Štěpán (advisor)
Diploma work „Multimedia player for iOS“ deals with the description of the video formats such as HLS, MP4, MPEG Transport Stream, and Dash. Next, it continues with protected content DRM, VAST advertisements and analytics tool called Google Analytics. During compilation of this diploma work was created a framework in programming language Swift. This framework is basically a player, that besides playing Interactive videos is able to show ads, subtitles, can change the video quality, AirPlay and download the content for offline playing. A feature to play a protected content could not be done as a developer's request for a product deployment SDK Fairplay was refused from an SDK owner. A testing app was also created that implements developed a framework and prove the functionality of the developed functions.

Multimedia Player for Android
Benedikt, Jan ; Číka, Petr (referee) ; Grabovský, Štěpán (advisor)
This thesis aims to create an advanced multimedia player with support of an adaptive stream, securing of the multimedia content and support for playing advertisement. The first part explains the used technologies followed by an analysis of available solutions and the comparison between the two. The theoretical framework is then used to create a player library and a testing application. The player library is based on the framework of ExoPlayer application. Whole application is created in Java for the operation system Android OS.

Video Format Support in Browsers and Possibility of Security Against Piracy
Bujok, Boris ; Kratochvíl, Martin (referee) ; Luhan, Jan (advisor)
The work deals with distribution primarily video content on the web and the possibilities of its security. The goal of thesis is to explore and summarize this comprehensive subject. The first part covers the basics of distribution, delivery methods, protocols, video formats. The second part deals with technologies that are commonly used on the Web and their comparison in different browsers or on mobile platforms. Including a look into the future, where these technologies would might take in relation to the development of a planned support, either in the browser or on mobile platforms.

DRM signal transmitter
Paták, Pavel ; Šebesta, Jan (referee) ; Lukeš, Zbyněk (advisor)
Master’s thesis deals with design and practical realisation of electronic circuits, which are needed for assembling of DRM signal transmitter for ham short waves bands. There is presented DRM standard as well as there are described the differencies between DRM for radio broadcast and for ham using. There is described design of input audio circuits, modulator, mixer, local generator, amplifier and filters. Principle of used SSB modulator is based on phase method, often called Tayloe modulator. This principle is analysed in detail including mathematical description, which was derived. It is possible to control the transmitter by program running at computer, communication takes place via USB. There is described establishment of communication in this work too.

DRM signal receiver
Mik, Šimon ; Charvát, Jiří (referee) ; Šnajdr, Václav (advisor)
The master’s thesis deals with the design of DRM (Digital Radio Mondiale) receiver. The block diagram of receiver was chosen and particular blocks were theoretically analyzed. After that followed design and production of each block. The synthesizer was programmed and the receiver properties were verified. The last part of thesis deals with real receiving of DRM broadcast.
