Model of HTTP adaptive video streaming
Kasianenko, Dmytro ; Prokopec, Jan (referee) ; Slanina, Martin (advisor)
Key tasks of this work are to create the simulation of a wireless network in ns-3 and to stream a video over this network by using MPEG-DASH technology. It describes the tools and methods how to encode a video according to MPEG-DASH. It is explained what is needed to run video server, which uses MPEG-DASH technology to stream videos. Then, it is described how a simulation of wired and wireless WiFi and LTE networks is created. The simulation starts a server and shows how it works, how many nodes can be used and chooses suitable segment duration.

Audio Streaming for Android Devices Using UPnP
Lehocký, Gabriel ; Španěl, Michal (referee) ; Beran, Vítězslav (advisor)
Velké množství lidí v současnosti používá své chytré telefony jako mobilní hudební přehrávač, kde si ukládá svou oblíbenou hudbu. Chceme-li při poslechu zvýšit hudební zážitek, tak toho můžeme docílit tím, že použijeme kvalitní externí soustavu reproduktorů, kterou připojíme přes wireless stream protokol UPnP a RTSP. Tyto protokoly umožní jednoduché sdílení hudby a jsou již implementovány v převážné většině audio-video zařízení. Tato práce si klade za cíl popis těchto technologií, na základě čeho popisuje i vývoj a realizaci jednoduché aplikace na sdílení audia.

Impact of rebuffering events on subjective QoE measurement of streaming video
Hůrek, Marek ; Pokorný, Jiří (referee) ; Kováč, Dominik (advisor)
This bachelor thesis mainly deals with the creation of a web-tool for subjective evaluation of quality of video in initial and repeated video loading and buffering. The simulation of adaptive streaming, focused on buffering, is performed on the basis of scenarios created in the database that are randomly generated and implemented into the aforementioned web-tool. The theoretical part of this thesis is focused on the analyzation of different types of streaming, streaming services and QoE service (subjective and objective evaluation). Two basic methods for the subjective evaluation (laboratory method and crowdsourcing) are described in more detail. At the end there are analyzed data received from measurement. Results are put into graphs with a description of subjective evaluation MOS.

The Netflix phenomenon and it's impact on the audience behavior
Doležal, Aleš ; Štoll, Martin (advisor) ; Jirků, Jan (referee)
The text of this diploma thesis called "Video on Demand Phenomenon and the Czech Viewer" describes the current situation in the world of the VOD services. It characterizes all the main elements of VOD and related business and viewer behavior and lifestyle resulting from those characteristics. The work also attempts to briefly describe all the main VOD services on the Czech market with regard to their history, current state and deals they offer to the viewer. The bulk of this work is, however, focused on the survey conducted amongst 140 people aged 19 - 26 and presenting its results. The survey finds that majority of those people prefer binge-watching over linear TV, which leads to very uneven TV watching habits and changes in lifestyle. According to the survey, it also appears that paid VOD is currently almost as popular as cable and satellite TV, but majority of people still don't want to pay for more than one service, which means that more than three quarters of them use internet piracy to get access to the desired content.
