This diploma thesis deals with the current phenomenon of video on-demand and the strategy of the streaming company Netflix when entering the European market. In the opening chapters it is necessary to explain the boom of the video on-demand services (VoD) in the context of television history and its position in relation to traditional linear broadcasting. Subsequently, the dramaturgical line and the programming offer of the company are presented , which is undoubtedly a competitive advantage of Netflix. In this context, Netflix's biggest competitors and their approach to production of original content are mentioned. The challenges Netflix is facing in its international expansion are also mentioned, including the need to tailor its offer and produce local content when entering new markets. Afterwards the European market as a whole is analyzed with regard to the specificities of the region and the key steps that were necessary to successfully start doing business on the continent. Last but not least, the thesis examines the position and development tendencies of Netflix in the field of original production in selected three European markets - Norway, France and the Czech Republic.

Evaluation of Capuchin Application Programming Interface : Implementing a Mobile TV Client

Feng, Xuan January 2009 (has links)
The purpose of this research was to evaluate the Capuchin API launched by Sony Ericsson at Lund, Sweden in 2008. The Capuchin API bridges Adobe’s Flash graphics and effects with JSR support from Java ME. We evaluated Capuchin API with regard to its suitability for a Mobile TV application. We tested this API in Ericsson’s TV lab where we had access to live TV streams and online multimedia resources by implementing a Mobile TV client. This test application was named “Min TV”, in English: “My TV”. Using Capuchin in the Ericsson TV lab environment has shown that it has some benefits, but also has many drawbacks. The Flash developer can be used to create an animated user interface and Java developers can do complex programming. At this early stage Capuchin technology is not mature enough, nor is it suitable for Mobile TV client development. Only after Sony Ericsson adds features such as soft keys, easier debugging of Flash Lite standalone applications, test emulator support in the software development kit, and more data communication methods than string and number, only then it will be a suitable technology for Mobile TV applications. Ericsson’s current Mobile TV application client was built using a framework called ECAF, which supports a graphics frontend and Java ME as backend. We compared ECAF and Min TV with respect to parameters such as: flexibility, performance, memory footprint, code size, and cost of skinning. (All these parameters are explained in detail in the methodology chapter.) As a possible future technology for Mobile TV, we evaluated a number of different presentation/graphics technologies including HECL, SVG Tiny, MIDP 3.0, .NET Compact Framework, etc. Moreover, we examed if a pure Flash Lite client application is a viable solution for Mobile TV. The comparison of different presentation technologies showed that Java ME is a comprehensive platform for mobile development offering all the necessary support from third party graphical user interface makers. .NET CF also looks like a good option for development with the scaled down capabilities for different programming languages supported using CLR. / Syftet med denna forskning var att utvärdera Capuchin API lanserades av Sony Ericsson i Lund, Sverige 2008. Den Capuchin API broar Adobe Flash grafik och effekter med JSR stöd från Java ME. Vi utvärderade Capuchin API med avseende på dess lämplighet för ett mobil-tv ansökan. Vi testade detta API i Ericssons TV lab där vi hade tillgång till TV-strömmar och online multimediaresurser genom en mobil-TV-klient. Detta test ansökan hette "Min TV", på engelska: "My TV". Använda Capuchin i Ericsson TV lab miljö har visat att det har vissa fördelar, men också många nackdelar. Flash-utvecklare kan användas för att skapa en animerad användargränssnitt och Java utvecklare kan göra komplexa programmering. På detta tidiga stadium Capuchin tekniken inte mogen, det är inte heller lämpliga för mobil-TV-klient utveckling. Först efter Sony Ericsson lägger till detaljer såsom mjuka nycklar, enklare felsökning av Flash Lite fristående program, testa emulator stöd i Software Development Kit, och mer data kommunikationsmetoder än string och antal, först då kommer det att vara en lämplig teknik för mobil-TV-program . Ericssons nuvarande mobil-tv ansökan klient byggdes med hjälp av en ram som kallas ECAF, som stöder en grafiska gränssnittet och Java ME som backend. Vi jämförde ECAF och min TV med avseende på parametrar såsom flexibilitet, prestanda, minne fotavtryck kod storlek och kostnaden för avhudning. (Alla dessa parametrar förklaras i detalj i den metod kapitel.) Som en möjlig framtida teknik för mobil-TV Vi utvärderade ett antal olika presentation / grafik teknik inklusive HECL, SVG Tiny, MIDP 3.0,. NET Compact Framework, etc. Dessutom har vi examed om en ren Flash Lite klientprogrammet är en hållbar lösning för mobil-TV. Jämförelsen mellan olika presentation teknik visade att Java ME är en övergripande plattform för mobila utvecklingen erbjuder allt nödvändigt stöd från tredje part grafiskt användargränssnitt beslutsfattare. . NET CF också ser ut som ett bra alternativ för utvecklingen med ned kapacitet för olika programspråk som stöds med hjälp av CLR.

Developing an emulator for 360° video : intended for algorithm development

Lindskog, Eric January 2020 (has links)
Streaming 360° video has become more commonplace with content delivery services such as YouTube having support for it. By its nature, 360° video requires more bandwidth as only a fraction of the image is actually in view, while the user is expecting the same "in view" quality as with a regular video. Several studies and lots of work have been done to mitigate this higher demand for bandwidth. One solution is advanced algorithms that take in to account the direction that the user is looking when fetching the video from the server; e.g., by fetching content that is not in the user’s view at a lower quality or by not fetching this data at all. Developing these algorithms is a timely process, especially in the later stages where tweaking one parameter might require the video to be re-encoded, and therefore taking up time that could otherwise be spent on getting results and continued iteration on the algorithm. The viewer should also be considered as the best experience might not correlate with the mathematically best solution calculated by the algorithm. This thesis presents a modular emulator that allows for easy implementation of fetching algorithms that make use of state-of-the-art techniques. It intends to reduce the time it takes to iterate over an algorithm through removing the need to set up a server and encode the video in all of the wanted quality levels when a parameter change would require it. It also makes it easy to include the viewer in the process so that the subjective performance is taken into consideration. The emulator is evaluated through the implementation and evaluation of two algorithms, one serving as a baseline to the second one, which is based on an algorithm developed by another group of researchers. These algorithms are tested on two different types of 360° videos, under four different network conditions and with two values for the maximum buffer size. The results from the evaluation of the two algorithms suggest that the emulator functions as intended from a technical point of view, and as such fulfills its purpose. There is, however, future work that would further prove the emulators performance in regards to replicating real scenarios and a few examples are suggested.

Výzkum regenerace filtračního materiálu zemních filtrů a kořenových čistíren odpadních vod / The Research on Regeneration of the Filter Material, used in the Soil Filters and Constructed Wetlands

Burešová, Hana January 2012 (has links)
The thesis consists of two basic parts. The first research part creates an introduction to the root zone wastewater treatment plants. It contains mainly causes of filter environment colmation and its theoretical solution methods, which are further solved in the laboratory. The master’s thesis attempts to find a simple way, which would in future be possible to evaluate the rate of sedimentation of the sludge material, which causes filtration environment colmation. Results of developed methodology will be used in practice by washing colmated filtration material, respectively colmatant separation in sedimentation tank. The thesis focuses to verify the possibility flocculation and mineralization of sludge, which adheres to the surface of the filtration material. The solution lies in the observation of sedimentation rate (after previous dilution) using by the turbidimetric method, based on the beam-column passage through muddy water. The results show that it is not critical ambient temperature, but the time effect of natural mineralization in combination with moisture (dry matter concentration, the amount of water). The present thesis evaluates the possibilities and application method, leading to the natural regeneration of the filtration material exposed to natural climatic conditions.

Pěček, Jan January 2010 (has links)
Industrial production of cellulose is an energy intensive process. Businesses aim to utilized as much input energy, materials as possible while minimizing the waste as well. In addition to the main product – cellulose and large amounts of organically polluted water which is subsequently treated in waste water treatment plants. This PhD thesis deals with formation of suitable mixing formula for sludge from cellulose production and available materials (waste) from close neighborhood of Biocel Paskov a.s. so that well balanced cofermentation products are achieved. This mainly involves grass from lawn maintenance, grass ensilage, potato peels, and leftovers from vegetable processing. Fermentation processes (both mesophilic and thermophilic) of prepared fermentation products were conducted in semi-continuous and continuous laboratory fermentation units. Reduction of organic mass depending on residence time was closely observed as well as production and quality of biogas along with quality of output digestate. Course of process behaviour under controlled pH was tested. Results of particular tests were integrated into graphs. Conclusion of the thesis presents balance scheme drawn for selected variants, and design of real fermentation station with individual buildings, operations, basic machinery and equipment description including investment costs. Financial calculation and expected investment return was conducted in two variants – without subsidies and including subsidies from Operational Programme Renewable Sources of Energy.
