General Description
NDS3522 HD/SD encoder & modulator is DEXIN’s consumer electronics which allow audio/video signal input in TV distributions with applications in home entertainment, surveillance control, hotel Digital Signage, shops etc.
It is an all-in-one device integrating MPEG-4 encoding and ISDB-T modulating to convert audio/video signals to digital RF.
The signal source could be from satellite receivers, closed-circuit television cameras, Blue-ray players, and antenna etc. its output signal is to be received by ISDB-T standard TVs or STBs etc.
