Product Details

NDS3542B DD AC3 Encoder Modulator

Outline

NDS3542B series products are DEXIN’s all-in-one devices which integrate encoding (MPEG-2, MPEG-4/AVC H.264) and modulation to convert HDMI/YPbPr /CVBS (Pr in) signals etc to digital RF output.

To meet customers’ various requirements, NDS3542B is also equipped with 1 ASI input, and output with 2 ASI ports and 1 IP port.

The signals source could be from satellite receivers, closed-circuit television cameras, Blue-ray players, and antenna etc. Its output signals are to be received by TVs, STB and etc with corresponding standard.

Dexin NDS3542B series products are wildly used in public places such as metro, market hall, theatre, hotels, restaurants and etc for advertising, monitoring, training and educating in company, schools, campuses, hospital… It’s a good choice to offer HD channels and more .
