Dexin NDS3548H digital modulator with 8 HDMI in

Product Overview

NDS3548H 8 in 1 Encoder/Modulator is an all-in-one device integrated encoding (MPEG-4/AVC H.264) multiplexing and modulation functions in one standard 1U case. It can convert 8 HDMI signals and 1 ASI input to 4 DVB-C RF out in the frequency range of 30~999MHz. It is also equipped with 2 ASI ports and IP port to output TS in 4* MPTS.

The signals source could be from satellite receivers, closed-circuit television cameras and etc. its output signal is to be received by DVB-C standard TVs or DVB-C STBs.

The device can be used in public place such as metro, market hall, theatre, hotels, resorts, etc for advertising. It also can be used for monitoring, training and educating in company, schools, campuses, hospital
