General Description NDS3552 encoder & modulator is a consumer product which allows 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 MPEG2 encoding and DVB-T/DVB-C/DMB-T/ATSC-T/ISDB-T modulating to convert video signals to DVB-T/DVB-C/DMB-T/ATSC-T/ISDB-T 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 a DVB-T/DVB-C/DMB-T/ATSC-T/ISDB-T standard TV, DVB-T/DVB-C/DMB-T/ATSC-T/ISDB-T STB etc.
