Abstract

The digitalization of terrestrial television broadcasting systems has been carried out in many countries around the world. Replacing the previous analogue video signal by the high-definition digital video has provided several technical benefits to the population, and nowadays it is an irreversible change. In Brazil, this process began in 2007, when the first terrestrial broadcasting of digital television was launched in Sao Paulo City. The Brazilian Digital Television system is referred as to ISDB-T B, because it is mostly based on the system called ISDB-T, which was originally developed in Japan. This paper presents a technical overview of this system in Brazil, and also reports its current status from a technical point of view regarding transmission features. Measurements of several transmission parameters are presented and followed by an analysis of the system situation in Brazil.
