Diploma thesis is focused on real-time 4K video encoding using NVENC technology. First chapter describes the most used video codecs H.264 and HEVC. There is an explanation of the principle of graphic cards and their programmable units. Analysis of the solution of open source Video Codec SDK is also part of the thesis. The main focus of the thesis is an implementation of an application which can handle 4K video encoding from multiple cameras in real time. Performance and qualitative tests were performed for application. Results of these tests were analyzed and discussed.

This thesis deals with processing of video content on Android platform. Libraries for video encoding and decoding usable on this platform are described first. One of these libraries - FFmpeg - is used as core to design and implement middleware video-processing library. This library will provide simple but e fective API for multimedia Java applications.

This thesis deals with advanced methods of digital video postproduction and distribution using broadcasting technologies and internet protocol. Describes and compares the distribution methods, using information technology and discusses the current problems. Describes digitization methods and methods that can save bandwidth for distribution. Deals with the possible practical implementation of distribution od three dimensional video to upcoming standards and analyzes the possibilities of their future development. Discusses the overall problems of transmission standardization and advanced video coding. In a conclusion, based on a comparison of methods and practical experience of the author, thesis recommends certain procedures to implement to the standard and specifies the direction of the technological solutions.

This thesis addresses video streaming from smartphone to smartwatch. The main goal of the thesis is to find a way how to handle the limited hardware features of the watch and make video streaming as fast and smooth as possible. A part of this work is focused on implementation of client-server application, which streams video from Android device to Tizen smartwatch over Bluetooth channel.

The aim of this thesis is non-realistic video rendering. It starts with a summary of existing techniques and then this thesis concentrates on selected methods that are able to work in real-time. To process video more effectivelly, we use accelleration on graphical processing unit with usage of OpenGL and GLSL.

The amount surveillance footage recorded each day is too large for human operators to analyze. A video summary system to process and refine this video data would prove beneficial in many instances. This work defines the problem in terms of its inputs, outputs and sub-problems, identifies suitable techniques and existing works as well as describes a design of such system. The system is implemented, and the results are examined.

Let's Play videos from the point of view of copyright law Abstract This Master's Thesis examines Let's Play videos (that are a new but significant and popular part of the entertainment industry) from the point of view of copyright law, especially the Czech one. The view of the European Union law is of course not omitted. With respect to the global nature of the issue, the Thesis includes selected foreign legislation, case law and expert opinions. Since the issue of Let's Play videos is new and almost unexplored, this Thesis examines and defines not only Let's Play videos but also their creators. It also identifies sources of income from Let's Play videos, persons involved and their interests, which can collide with each other. Given the existential interdependence of Let's Play videos on videogames, this Thesis examines even some relevant copyright aspects of videogames. Besides the question of copyright classification of Let's Play videos, the Thesis also deals with not so obvious consequences of such classification. There are analyzed possible legal titles for the use of video games and their elements in the creation, publication and monetization of Let's Play videos as well. Subsequently, this Thesis also examines and analyses the current worldwide licensing practice in this field. Despite the fact, that...

The diploma thesis deals with specific features of spoken communication in videos of so-called YouTubers that are available on the website YouTube. The aim of the presented diploma thesis is to show the state of the Czech YouTube production from the point of view of language. The theoretical part of the thesis deals with differentiation of national language and especially with slang. The empirical part consists of a short dictionary that shows the main principles of YouTube videos. In the following text different kinds of these videos are introduced and then three categories are analyzed in details: spoken form, slang terms, and language means. The diploma thesis is supported with a wide range of examples.

Téma doktorské práce je zaměřeno na analýzu zpracování signálů v širokopásmových multimediálních sítích a systémech budoucnosti, kde se předpokládají systémy s ultra vysokým rozlišením (UHDTV), vysokým snímkovým kmitočtem (HFR) a stereoskopické systémy (3D). Tyto systémy budou umožňovat vysoce účinnou zdrojovou kompresi obrazu, zvuku a dat a také jejich vysoce účinný přenos, a to jak při volném vysílání (např. DVB-T2), tak ve službách placené televize (např. IPTV). Cílem práce je analýza a vyhodnocení kvality obrazu a služeb v těchto systémech na základě objektivních metrik a subjektivních testů. Práce se dále zaměřuje na analýzu vnímané kvality u stereoskopické televize, kódovací účinnost moderních stereoskopických enkoderů a vlivu sekvencí na uživatelský komfort.

This master thesis is oriented on a problem of creating video and image annotations. This problem is solved by crowdsourcing approach. Crowdsourcing games were designed and implemented to make solution of this problem . It was proven by testing that these games are capable of creating high quality annotations. Launching these games on a larger scale could create large database of annotated videos and images.
