NDS2405 ISDB-T modulator

Outline

NDS2405 ISDB-T modulator is developed to adapt Japan, Brazil, Argentina and other South American country's terrestrial digital television, the modulator's channel coding and modulation mode is fully complying with the ARIB STD-B31 standard. This ISDB-T modulator supports four TS hot backup input, single frequency network and multi-frequency network, linear and nonlinear pre-correction function, layered transmission and the three transmission modes mentioned in the standard. Furthermore, this device can be upgraded and controlled through network system, which can be widely used in ISDB-T digital broadcasting network's setting up and set-top box design's production and test.
