Introduction

Outline

COL5601J 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 two ASI and two IP 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.
