Baseband Transmission Quality Estimation for DVB-T2 Broadcasting System (Part 1)

Journal Title: Цифрові технології - Year 2018, Vol 1, Issue 23

Abstract

The article presents the results of research in the direction of determining the permissible values of parameters that are controlled in the baseband during the evaluation of the quality of the operation of the transmitter-receiver of digital terrestrial television system in DVB-T2 standard at the transport stream level. The main purpose of this study is to obtain quantitative and qualitative assessments of controlled parameters at the level of transport multi-program stream in the base band of digital terrestrial television broadcasting systems that are currently not available in national and international technical literature. In order to achieve the research aim, a mathematical simulation model of the DVB-T2 digital transmission TV transmission system (transmission path, channel with distortion, receiving path with appropriate processing and correction) was implemented in the Matlab / Simulink environment and a computational experiment was carried out, the results of which were analyzed in relevant way of experimental data is the basis for formulating the corresponding requirements to the level of distortions at the level of the base band stream. As a result of the conducted studies, evaluations were made of the appropriate parameters used to control the quality of digital TV system operation at the level of the digital transport multi-program stream. The obtained values can be used for standardizing and monitoring the level of distortion during the technical operation of the receiving and transmitting equipment of the relevant standard, as well as certification and commissioning during the introduction of new equipment, as well as the deployment of digital terrestrial television networks.
