Video on Demand service in JavaME
Obdržálek, Petr ; Müller, Jakub (referee) ; Číka, Petr (advisor)
The master’s thesis deals with creation of system that provides video on demand. Technologies which are used to creation mobile application are analyzed. There are also mentioned today's most used codecs in the mobile devices. There are described standards, norms, principles and recommendations for transfer multimedia data on network in real time. Technologies which are appropriate for functionality of system on server side are described. The output of the work is an operational sample of whole system and description of functionality of this system.

Camera Recording Management System
Šulc, Ondřej ; Rychlý, Marek (referee) ; Očenášek, Pavel (advisor)
The aim of this bachelor thesis is to create a network security system focusing on compatibility with the widest possible group of IP cameras from various manufacturers and support for remote access to records even from places outside the local network. This problem is solved using two closely cooperating applications. The first application runs on a device in the local network (in our case miniPC Raspberry Pi). The application creates the records by receiving and storing RTSP transmissions from individual cameras. It then modifies these records into a form usable for display on websites and sends the second application from which the user can access them. This application is referred to in the text as agent or agent application. The second application has a web user interface and serves the end user as a tool to manage agents, IP cameras and captured records. By principle of the application, it is important for it to be accessible on a publicly available domain. This application is referred to in the text as web or web application. The use of this architecture does not violate any of the network communication standards, which include, in particular, the initialization of communication from the network behind the NAT service.

Transmitting Streamed Video on Windows Phone
Jež, Adam ; Zachariáš, Michal (referee) ; Herout, Adam (advisor)
The main goal of this bachelor thesis is the design and implementation of an application for mobile system Windows Phone which will be able to broadcast a multimedia stream from the mobile device camera via a packet network. The RTSP protocol is used to establish the connection and to negotiate the transmission conditions. The multimedia data themselves are sent via the RTP protocol. The aforementioned protocols and follow protocols such as RTCP and SDP are described in the thesis. Also the development of the multimedia application for Windows Phone is briefly described. The last part of the thesis deals with the impact of the transportation protocol on the quality of the video. The main result of the thesis is an application almost ready to be published.

IP Television
Mašek, Pavel ; Fojtová, Lucie (referee) ; Číka, Petr (advisor)
The main objective of thesis is proposal and realization programme, which can be able to receive and play up multimedia stream broadcasted from server via packet networks. Protocol for transmission multimedia data is used to join connection between server and end point. And therefore protocols which handle data transmission like RTP/RTCP, RTSP and also SDP and SAP are described in thesis. Description mentioned records isn't effected to the smallest details, but acts about acquaint with problems. Further be brief described libraries that the stand by drafting application in view as well as used application that the function as the source of transmission multimedia. Than follows proposal solving and single step description of programme design in thesis. Analysis of working programme is performed in the last part of thesis.

IP Cameras Control Library
Schmied, Jan ; Rozman, Jaroslav (referee) ; Luža, Radim (advisor)
This thesis describes the design and implementation of a library that allows control of IP cameras and receives multimedia streams. The thesis briefly introduces standard interfaces of IP cameras and describes in detail VAPIX interface. This interface is also demonstrated by examples. The practical part deals with the design and implementation of the library using the FFmpeg and cURL libraries. Library is subject of a measurement that shows its performance.

Video Capture and Compression on Embedded Devices
Dušek, Oto ; Chlubna, Tomáš (referee) ; Bařina, David (advisor)
Industrial cameras are often used in conjunction with the application of machine learning. However, these cameras produce large bitrate and it needs to be reduced when processing video further away from the camera. This thesis tries to solve the problem by design of system suitable for grabbing video from industrial cameras, its compression and distribution to machine learning application. The thesis describes technologies applicable to the development of the multimedia application. For example frameworks FFmpeg and GStreamer were used implementation of the system.

System for Recording Video from IP Videocameras
Travěnec, Jiří ; Michal, Bohumil (referee) ; Skokanová, Jana (advisor)
This diploma thesis focuses on multimedia streaming from IP cameras. Its main goal is to explain theoretical background of real-time streaming via computer networks, and describe development of a recording system. This recording system is meant to be used mainly in schools for lecture recording purposes. The thesis contains description on how a recording server application and web-based management system were developed. The theoretical part explains topics related to multimedia streaming, networking, and multimedia procesing, such as real-time streaming protocols, encoding, compression, network latency, network congestion and many others.

Video on Demand Protocols Testing using Apache JMeter
Srnec, Tomáš ; Smékal, David (referee) ; Číka, Petr (advisor)
The master’s thesis deals with testing the application protocol HLS and RTSP in JMeter program. The aim of this thesis is to design and implement a test modules for both protocols, which will perform stress tests. The first part of thesis describes the types of stress tests, JMeter program for performance testing and video on demand services. Next chapter describes selected protokols, especially HLS and RTSP, which are used in this thesis. The practical part contains the design and implementation of test modules including test plans. Finally, the results are processed and commented.

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.
