NDS3542C MPEG2 HD MPEG4 HD 2-in-1 encoder modulator

NDS3542C series products are DEXIN’s all-in-one devices which integrate encoding (MPEG-2, MPEG-4/AVC H.264) and modulating to convert HDMI/YPbPr /CVBS (Pr in) signals etc to digital RF output. To meet customers’ various requirements, NDS3542C is also equipped with 1 ASI input, and output with 2 separate 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 NDS3542C 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.
