2. Abstract The debate surrounding the choice of digital TV format in Brazil resulted in a sense of expectation on its innovative aspects of broadcasting. After choosing the ISDB-T format though, as anticipated by analysts, Brazil has been facing the challenge of developing lower cost set-top boxes to take advantage of main Japanese format features: mobility and spectrum availability for interactive applications.
