ISDB-T Modulador Brasil Paraguay Argentina Peru Chile Ecuador Sudamericano ARIB STD-B31 standard ISDBT Modulador
Outline
HPS3848G 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.
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)
7. Supports adaptive linear digital pre-distortion (DPD)
8. Supports adaptive non-linear digital pre-distortion (DPD )
9. MER≥42db
10. RF output range: 50~999MHz with 1Hz step
11. Constant temperature crystal oscillating and excellent frequency stability (up to 0.1ppm)
12. WEB, Keyboard and LCD operation
