LinuxDays in 4K on the Internet

Prague 7 October 2014. CESNET transmitted live Internet broadcasts in 4K (3,840×2,160 pixels) from LinuxDays at the weekend. Viewers could watch the broadcasts on a large displaying device in the SAGElab, an online multimedia lab at the Faculty of Information Technologies, Czech Technical University. Lectures taking advantage of the high resolution took place directly at the SAGElab.

LinuxDays is a Linux conference held annually in Prague. It was established in 2012 as a successor to a previous conference, LinuxExpo. This year’s conference was held on the premises of the Czech Technical University. About 40 papers were presented in three lecture halls. The body of lectures included contributions from CESNET representatives: two presentations named How the Internet is Measured and IPv6 in OpenWRT by Ondřej Caletka and a paper named 100 Different Ways of Backing Up by Michal Strnad.

The SAGElab was established last year for research and teaching of the latest networking and multimedia technologies. It is a joint workplace of CESNET, the CTU Faculty of Information Technology and the CTU Faculty of Electrical Engineering. The laboratory is used for long-distance lectures and teaching of subjects in the areas of multimedia, virtual reality and networking technologies. In addition, it is used for independent research activities of students working on their thesis or dissertation and other experts in the area of networking and multimedia technologies. It is also connected in the international community of laboratories with a similar focus.

The Faculty of Information Technologies was established in 2009, becoming the eighth Faculty of the Czech Technical University (CTU) in Prague. Today, it offers a broad range of study specialisations connected with computer science: from hardware to information systems and web technologies. Furthermore, students can become involved in the work of the faculty’s scientific teams in many specialisations, such as arborology and stringology, knowledge engineering and data mining, VLSI design, computer security, database design, parallel algorithms, web engineering, and more.

The CESNET Association was founded by Czech universities and the Academy of Sciences of the Czech Republic in 1996. It is engaged in research and development in information and communication technologies and builds and develops the CESNET national e-infrastructure for research and education. With its research activities and accomplishments, CESNET represents the Czech Republic in international projects, most notably the pan-European GÉANT network building project and grid projects (EGI.eu), and participates actively in their implementation. Among other things, the association deals with the use of high-speed networks for sharing multimedia data both through synchronous video conferencing and shared applications and asynchronous streaming.
