NDS3542 MPEG2 HD/MPEG4 HD Encoder Modulator
Product Overview
NDS3542 series products are one branch of DEXIN’s knock-out all-in-one devices which integrate tuning (DVB-S/S2, ISDB-T) or encoding (MPEG-2, MPEG-4/AVC H.264) and modulation (DVB-C, DVB-T/T2, ISDB-T, or ATSC) to convert V/A signals into RF output. This sheet is going to introduce a 1U rack model which integrates MPEG-2 HD/MPEG-4 HD video encoding and DVB-C modulation to convert HD A/V signals to DVB-C RF out in the frequency range of 30~960MHz.
It adopts inner drawer-type structural design which greatly facilitates the change of encoding modules (HDMI/CVBS/SDI/YPbPr/…) as needed. To meet customers’ various requirements, NDS3542 is also equipped with 1 ASI input, and output with 2 ASI ports and 1 UDP 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.
With its various inputs available, our NDS3542 series products are wildly used in public places such as metro, market hall, theatre, hotels, resorts, and etc for advertising, monitoring, training and educating in company, schools, campuses, hospital… It’s a good choice to offer HD channels and more.
