The goal of the tests is to compare these systems under Brazilian conditions. The results shall be passed on to Anatel along with a report on the best system for Brazil. According to president Renato Guerreiro, Anatel's role is predominantly a coordination one. He also points out that this technological convergence is fundamental for the country to become part of this new information society.

Tests to evaluate the behavior of ground digital TV in Brazil are in compliance with the procedures established by Anatel through its Resolution 68 of November 1998 and are being conducted in two stages, through field and lab tests. The field tests have the goal to evaluate and establish a comparison between analog and digital systems. For the PAL-M analog system, a Linear transmitter with a 1kW power peak will be used. The signals by Ihese transmitters are radiated by means of a Transtel manufactured antenna, slot type, with a directive transmitting diagram. In order to evaluate the behavior of the digital signals next to its companion analog and digital signals, a digital transmitter manufactured by Continental will also be installed, operating on channel 35, using an identical antenna to that used on channel 34, aside from the linear analog one.
