Product Description
OutlineHPS384A ISDB-T modulator is developed to adapt Japan, Brazil, Argentina and other South American country's terrestrial digital television. The modulator's channel encoding and modulation mode is fully complying with the ARIB STD-B31 standard. This ISDB-T modulator supports four ASI hot backup input, single frequency network, and multi-frequency network. In order to improve the output performance of the transmitter, this ISDB-T modulator also simultaneously supports adaptive linear and nonlinear digital pre-distortion, layered transmission and three transmission modes. 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.
