Details:

ISDB-T/Tb BTS 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/Tb BTS 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/Tb digital broadcasting network's setting up and set-top box design's production and test.
