Hardware and Software Complex for Digital Television Signals Generation and Research

Nowadays, there is a rapid development of digital TV and radio broadcasting technologies in the world. It makes the task of improving the training level of students of higher educational institutions studying in specialty “Telecommunications and Radio Engineering” of current interest. The thesis formulates the relevance and necessity of creating a hardware and software device based on Dektec modulators for a more detailed and in-depth study of the signal processing methods and its generation the digital terrestrial and satellite television broadcasting systems, which can be used in the educational process of higher educational institutions for training specialists for the telecommunications industry. This thesis discusses the Dektec modulator boards, which can be used to generate modulated radio signals from a number of European standards for digital television broadcasting DVB-T, DVB-C, DVB-S and DVB-S2. This article describes the basic information about the software package based on CrazyScan and TSReader applications, which are used to study signals on the receiving side and reproduce multichannel TV transport streams that are being transmitted. It also provides basic information for working with StreamXpress software for generating digital TV broadcast signals. The main options for constructing the proposed hardware and software complex based on terrestrial radio channels of the decimeter (UHF) and centimeter (SHF) range for the generation and study of digital television broadcasting signals based on the Dektec DTA-107S2 and DTA-115 modulators are presented.
