Sistema de TV digital: uma proposta de implementação de um sistema de radiodifusão em TV digital no município de Boa Vista - Roraima

Abstract

The implementation of the Brazilian Digital Terrestrial Television System (SBTVT) in 2006 marks a significant advancement in the Brazilian television landscape, providing substantial improvements in audio and video quality, as well as the introduction of interactive features. However, the transition faces technical and logistical challenges, particularly in cities like Boa Vista, Roraima, where infrastructure and population dispersion in urban and peripheral areas hinder the implementation of digital TV. This study aims to evaluate the feasibility of implementing digital TV in Boa Vista by analyzing signal coverage and reception quality, with a focus on the city's adaptation to new technologies. The methodology involves a combination of simulations using ICS Telecom software and field measurements to assess signal performance. The research aims to analyze both the technical challenges and the economic and social factors involved, promoting digital inclusion and expanding access to information. By comparing the results of simulations with actual measurements, the study will refine signal propagation models, ensuring that the population of Boa Vista has adequate access to the benefits of digital TV, such as superior audio and video quality and interactivity. The study is justified by the need to ensure broad and efficient coverage in all areas of the city, strengthening social and digital inclusion and ensuring the dissemination of educational, cultural, and informative content for the local population
