Overview
NDS2405G ISDB-T modulator is developed to adapt 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. Key Features: 1. Fully complying with ISDB-T (ARIB STD-B31) and ISDB-TB standard; 2. Dual channel ASI input, 10MHz reference clock and 1PPS in; 3. Dual IP input ports, GE ports, over UDP/RTP; 4. Layered transmission with A, A+B, A+B+C hierarchy modes; 5. ISDB-T BTS input (with IIP packet), support single frequency and multi-frequency network; 6. Three transmission modes: mode1(2k), mode2(4k), mode3(8k)
