Screen Sharing
Radimák, Samuel ; Zachariáš, Michal (referee) ; Kajan, Rudolf (advisor)
The following bachelor thesis is dedicated to the description of methods for a desktop sharing and possibilities which these methods provide. In the beginning, principles connected with the concept of desktop sharing are explained. Moreover, there are described various solutions, which had already existed before my research. In addition, fundamental protocols for the transfer of the screen and main differences between them are mentioned. The most extensive part is devoted to the design and the implementation of an application for screen sharing. The application is split into two parts, a client and a server. The development is described with the use of UML (Unified Modeling Language). For the transport of the screen, RFB (Remote Framebuffer) protocol has been chosen. In advance, reduced description of this protocol is mentioned in this text. The developed application is tested and compared to other existing solutions. Finally, areas where improvements are possible are stated.

Desktop sharing through video- and audio-conferences
Zukal, Martin ; Morský, Ondřej (referee) ; Číka, Petr (advisor)
The following diploma thesis is devoted to the desktop sharing description and its opportunities. Existing solutions and their advantages and disadvantages are described at the beginning of the text. The most extensive part deals with the design and the implementation of a new solution for the desktop sharing. The thesis aims at providing a possibility to observe desktop of one computer from another one. For achieving it, two appliactions (a server and a client) have been developed, and they are described in the text with utilization of UML (Unified Modeling Language) diagrams. The RFB (Remote Framebuffer) protocol has been chosen as the means for communication between the applications. A detailed description of this protocol is also included in the text. The developed solution is tested and compared with other similar applications in the final part of the work. After that, some areas needing slight improvements are named to achieve competitiveness of the developed solution with other applications of a similar type.

Processing and Streaming Video in Browser for Screen Recording
Svačina, Lukáš ; Beran, Vítězslav (referee) ; Španěl, Michal (advisor)
Aim of the thesis is to design and implement unique service based on the newest technologies in web apps fi eld which allows screen recording followed by P2P distribution between participating users using web browser only. Thesis deals with the analysis of modern and coming technologies which allow practical implementation of such a service. It involves obtaining access to the screen source data, its recording, transforming and transmission over the network followed by playing on the other side. Recorded videos are adapted for part by part use in a player with seeking capability. Distributed architecture for data exchange between peers using peer-to-peer connection based on hybrid P2P VoD network provides scalability of the solution. The player allows obtaining the necessary parts of the videos from the current watchers with smooth video playback experience during ongoing transmissions whilst allowing arbitrary video shifting. In consideration of early stages of development or experimental support for some of the APIs needed for this work, research into browsers' support with discussion on realistic applicability nowadays is always performed.
