ISDB-T is the terrestrial digital TV which is developed for adapting the South American countries such as Japan, Brazil, and Argentina and so on. The channel coding and the modulating of the modulator are fully supporting ARIB STD-B31 standard, supporting double TS hot spare inputting, supporting single frequency network and multiple frequency network, supporting the function of linear and non-linear pre-correction and also supporting layered transmission and the three standard transmission modes. Moreover, the system of the modulator can be online upgraded and controlled by network; thereby the modulator can be widely used for setting up ISDB-T digital broadcasting network and producing and testing the designs which are living up to the ISDB-T standard’s set top box.
