Outline
NDS3922A is a professional audio decoding device with powerful functions. It supports 1 tuner input for DVB-CDVB-TDVB-T2ISDB-T(switchable) or DVB-S/S2/S2X demodulation, 2 ASI inputs and 2 IP inputs. And it supports decoding the analog balanced audio (XLR interfaces) and AES/EBU digital audio (XLR interfaces), 2 SPTS outputs over UDP/RTP. Its high compatibility and excellent decoding quality makes this device widely used in the digital broadcasting system.
