HDMI and VGA input dvb t encoder modulator

Product Overview

Description

 NDS3542 Encoder Modulator 

HDMI/VGA to DVB-T/DVB-C/ATSC/ISDB-T

 

 

NDS3542 series products are one branch of DEXIN’s knock-out all-in-one devices which integrate encoding (MPEG-2 HD, MPEG-4/AVC H.264) and modulation (DVB-C, DVB-T, ISDB-T, or ATSC) to convert V/A signals etc into RF output. This sheet is going to introduce amodel which converts  HDMI/VGA signals to DVB-T/DVB-C/ATSC/ISDB-T 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.
