Product Overview
NDS3554 series encoder & modulator is DEXIN’s consumer electronics which allow audio/video signal input in TV distributions with applications in home entertainment, hotel Digital Signage, shops etc.
It is an all-in-one device integrating MPEG2 HD/SD and MPEG4 AVC H.264 HD/SD encoding and modulating to convert video/audio signals to digital RF out in the frequency range of 30~960MHz.
The signals source could be from satellite receivers, closed-circuit television cameras, Blue-ray players, and antenna etc. Its output signal is to be received by TVs or STBs etc.
Key Features
* Support HDMI/YPbPr/CVBS input
* Support 1 DVB-T/DVB-C/ATSC RF out
* MPEG2 and MPEG4 HD/SD video encoding
* Dolby digital AC3 (2.0) audio encode, AC3 passthrough (for HDMI interface only)
* USB record, playback and upgrade
* Low Delay
