Web application for subjective evaluation of streamed video
Lipa, Matúš ; Červenák, Rastislav (referee) ; Kováč, Dominik (advisor)
This work deals with creating web application for subjective evaluation of streamed video and parts which are necessary. Streaming techniques are described from simple classical technique to adaptive bitrate streaming techniques. This work focus on adaptive bitrate streaming technology using MPEG - DASH and editing video source with tool FFmpeg. With using JavaScript is create a player who´s able to simulate changes in the network as a change in available bandwidth. It´s possible to create scenarios under which the player selects the video playback quality. The player is placed into a complex tool for evaluation of quality of experience.

Technology for webcast
Švehlák, Milan ; Číka, Petr (referee) ; Zeman, Václav (advisor)
This bachelor´s thesis discusses technology for creating webcast and possible methods for its implementation. To begin with, there is mentioned theoretical knowledge about the transmission of multimedia over the Internet. This is followed by a list of basic methods for webcast. In the following parts, these various methods are described in detail with their advantages and disadvantages and they are compared. This thesis also discusses the hardware and software tools necessary for implementing the webcast. Finally, there is a design suggestion for the most appropriate method for making a webcast with respect to the stipulated requirements and subsequently made its implementation.

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.

Web Based Audio/Video Lecture Browser: Porting of the Browser to MySQL Database
Janovič, Jakub ; Fapšo, Michal (referee) ; Szőke, Igor (advisor)
This project deals with a web-based lecture browser, whose goal is to simplify the gaining of knowledge with the use of multimedia. It presents an existing lecture browser that was created for a diploma thesis at FIT VUT Brno. Demonstrated are the technologies that are used and which will be used to migrate the browser to a MySQL database and to develop a transcription module for speeches. The reader will be acquainted with an analysis and model of the new application. Furthermore, implementation methods for development and subsequent testing are discussed. At the end of the project is a conclusion about the future development of web-based lecture browsers.

Video-Conference System for Remote Education
Holán, Josef ; Szőke, Igor (referee) ; Schwarz, Petr (advisor)
The main goal of this thesis is to design videoconferential system by Java Media Framework. This means to write two programs. One will capture multimedia data from webcam and will sent it into network. The second application which can receive this data is supposed to be on another computer. The multimedia data are transmitted by using Java Media Framework library. We suppose one lector and group of students. Video and audio channel is transmitted to all students. Communication between lector and student is solved using chat. Lector has possibility open another audio or video channel with all students. Multimedia data will be transferred using Real-time Transport Protocol (RTP). The message including information about student is transferred by Transmission Control Protocol (TCP).

Intelligent Passive Client for Music Player Daemon
Winkler, Tomáš ; Kočí, Radek (referee) ; Janoušek, Vladimír (advisor)
Music has always been integral to our lives. It is very appropriate to use not only our sense of hearing but the other senses as well to intensify our enjoyment of music. My goal in this bachelor's thesis was to appropriately enhance functionality of existing clients for a music player daemon so that it could be achievable to watch certain presentation when playing music. An aplication uses internet sources to download suciant amount of pictures. Another sources can be add using an aplication interface. In this thesis I also solved a problem of duplicity image detection and a problem of download sources rating from various sources. Of course it can show an interpret's name and a playing song's name during picture presentation. This thesis is about creating a draft, a discription and an impelmentation of inteligent passive client which should go public.

The assessment of the capacity of bridge profiles on the Bobrava river
Bezděk, Josef ; Roubcová, Radka (referee) ; Milerski, Rudolf (advisor)
This diploma thesis “The Assessment of the Capacity of Bridge Profiles on the Bobrava River” focuses on making calculations of a system of bridges by using HEC-RAS PC software. This thesis assesses the capacity of bridges and applies knowledge of model research to design increase the capacity. A model of a stream on Bobrava River will be created. Furthermore, modifications of a river bed and bridge profiles will be realized for safe conversion Q100 by these constructions. Subsequently, a model of the modified stream n Bobrava River will be made. Lengthways profiles of water surface, table and graphic outputs from HEC-RAS PC software and modified designs will be output.

Compression, decompression and streaming of video data
Šilhavý, Miroslav ; Číka, Petr (referee) ; Burget, Radim (advisor)
The Bachelor thesis is focused on description of FFmpeg tool and theora codec abilities. Comparison of capabilities and technologies within MPEG-4 (MPEG4- ASP, H.264), Theora and MPEG-2 codec. Testing the compression efficiency and output image quality of codecs x264 and Theora. Further I mentioned samples of using Theora and FFmpeg programming interface for video handling. Part of the thesis is also analysis and implementation of the player based on FFmpeg libraries and application for streaming Theora encoded video packets by RTP protocol.
