Detailed Description

Outline DVB-T/H Modulator supports DVB-T/H standard channel coding and modulation parameters. A/V signals compressed and coded via MPEG-II and be multiplexed and processed together with other data stream, then send to DVB-T/H modulator. Modulator channel coding process is full according to DVB-T/H technical specifications and achieve energy proliferation, interweave, FEC coding, RS coding, symbol mapping, filter matching etc. After that modulated by COFDM and output IF. IF through built in up-converter generate the required RF output. Widely used for terrestrial digital television broadcasting, mobile data broadcast and digital broadband applications. Main Feature  Meet EN300744 standard; support 6MHz/7MHz/8MHz band width  Error correction follows DVB-T standard  Operable in QPSK, 16QAM, 64QAM mode  Support 2K/8K carrier-wave operating mode  FEC encode supports 1/2、2/3、3/4、5/6 and 7/8  Secure time interval supports 1/4、1/8、1/16、1/32  Input interface: ASI and SPI（DS3/E3 optional）  Input bit rate::1.5～31.67Mbps  Output band width：6/7/8MHz  RF output：48～860MHz  Output level：105dBuV～115dBuV(step adjustable)  188 and 204 packet automatic identification; shows real-time data format  Adopt high capability buffer; ASI interface supports burst and equality TS, while re-construct equality TS.  Advance output TS efficiency  Capable of NIT mapping and sending; supports over 44 NIT mapping frequency  Holds 10 groups of PID filtering and re-mapping function  Support all PSI/SI data abstraction, modification and analysis  Capable of swiSVhing/inserting SI data  Null packet filtering and filling  Performs multiple PCR correction simultaneously  Monitor and test real-time enter/valid bit rate  Self-adjust filter circuit design in order guarantees superb SNR (out of band)  -20dB RF test output is available (IF output is also available)  Failure alarming  LCD display  With RJ45, actualize central NMS, distant upgrade/maintenance (NMS software is optional)  Power off memory
