Abstract
The aim of this work is to design headend suitable for nationwide DVB-T2 network in the Czech Republic. Basics of digital terrestrial broadcast standards DVB-T and DVB-T2 and data compression methods such as MPEG2, H.264/AVC and HEVC are described. The second part is focused on design of overall layout topology for headend, and individual parts and their detailed description. This section contains block diagrams of each part of topology: compression, conditional access, statistical multiplexing, SFN adaptation, as well as monitoring of the content and devices. Also there is draft addressing the power supply for headend. The third section is a market survey selecting the main example of the products and stating their replacements.
