The paper concludes that the technical superiority of the ISDB-T system and its robustness and flexibility are clear. ISDB-T's great flexibility turns out to be an important competitive advantage, enabling a more flexible business model. Brazilian broadcasters are focusing on the simultaneous transmission of an HDTV signal and a robust signal for mobile reception. The ABERT/SET tests clearly indicate that this can be best achieved by the ISDB-T system. The performance of ISDB-T is much better than that of the other systems, since the maximum payload for reliable reception is significantly higher. This is mainly due to the time-interleaving established in the ISDB-T standard.
