Cobertura de TV Digital: Avaliação Subjetiva e Medições Em um Cenário Real

Abstract

Open and free Digital TV remains an important and popular service in Latin America, specially in Brazil with the implantation of the Brazilian Digital Terrestrial Television System (SBTVD-T). This paper presents a case study of power measurements obtained according to the ABNT 15604/2017 standard, aiming to compare the coverage area of the digital television service in the city of Natal with that projected with SIGAnatel, which runs the point-to-area prediction method ITU-R P.1546. As a main result, we intended to fill the gap with technical material related to the discussion of digital TV in Brazil by presenting measures of power from stations in operation as well as subjective signal quality evaluations provided by final users for comparison purposes.
