Outline
The DEXIN NDS3402 DVB-S2 modulator is a high performance modulator developed according to DVB-S2 (EN302307) standard which is the standard of second generation of the European broadband satellite telecommunication. It adopts advanced framing structure, channel coding and modulation technology, increasing over 50% transmission ability more than DVB-S modulator under the same transmission condition and also providing a more powerful receiving ability in the same spectral efficiency. In addition, it is backwards-compatible with DVB-S (EN300421) modulating standard. This DVB-S2 modulator supports local and remote control through NMS software. The NDS3402 DVB-S2 modulator can be used for Broadcasting, Interactive Services, News Gathering and other Broadband satellite applications.

Outline NDS3915 DVB-S2 HD IRD with CI slot can decode transport stream from ASI, tuner or IP sources into audio & video signal. With the help of CAM module, it can decrypt the encrypted programs in the input TS. Apart from this function, it also can encapsulate the output TS into IP pocket and output in UDP protocol. User can watch the contents of the IP outputs from decoding software on computer. The professional IRD has full-range of output interface ports, such as HD-SDI, SD-SDI, HDMI, YPbPr, XLR, S/P DIF, etc., which can satisfy the professional users needs. Features Factory optional for DVB-S/-S2/-T/-C, ISDB-T tuner inputs MPEG-2 (MP@ML&MP@HL) and MPEG-4 Part 10 ( AVC high profile level 4.1) standards complaint and decoding Various choice of I/O interfaces, including ASI input/output, CVBS output, YPbPr output, HDMI output, SD/HD output (embedded 2 pairs stereos audio), AES/EBU output, 10/100M TS over IP input/output ( optional) Built-in re-multiplexer ( temporarily unavailable ) VBI Teletex , Subtitile support Caption support 10/100M Ethernet TS over IP I/O, UDP protocol Unicast and multicast support Two DVB-CI slots, multiple programs decryption support NMS control support Specifications RF interface Input frequency 950í½2150MHz Input level -65í½-25dBm Signal input type F interface Input impedance 75 Ω Symbol ratio 1-45Msymbols Demodulation mode QPSK, 8PSK Frequency stepping 500KHz Weight: 5kg Dimensions:482mm*455mm*44.5mm
