Product Overview

NDS3542A is a modular all-in-one device which integrate encoding (MPEG-2 HD, MPEG-4/AVC H.264) and modulating to convert V/A signals into DVB-C/DVB-T/ATSC-T/ISDB-T RF output. It is equipped with 4 HD-SDI input and 1 ASI input and output with 2 ASI ports and 1 IP (4*SPTS or 1 MPTS) over UDP, RTP/RTSP through data 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 or STBs and etc.

With its various inputs available, our NDS3542A 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.
