This paper analyzes the process of building the single frequency network for digital terrestrial video broadcasting. We will show the comparison of DVB-T and DVB-T2, when planning a single frequency network. A single frequency network is used for optimizing spectrum usage and bandwidth. DVB-T2 is a standard for digital television broadcasting, offering significant benefits compared to DVB-T. DVB-T2 includes many new techniques, not previously used in DVB-T standard. In this paper, main properties of DVB-T and DVB-T2 standards are shown, as well as the principle of the OFDM modulation. The paper ends with the summary and conclusions.
