Bộ Điều Chế DVB-T Dexin NDS3544I chuyển tín hiệu IP/HDMI/RF sang IP/ASI/RF chuẩn DVB-T/C/ATSC/ISDB-T

NDS3544I_Encoder_Modulator-1

NDS3544I is a professional high integration device which includes encoding, multiplexing, scrambling and modulation. It supports 8/12/16/20/24 HDMI input, one DVB-C (ATSC optional) tuner input and maximum 512 IP input with Data1 (GE) port. It also supports DVB-C RF out with 16 non-adjacent carries or DVB-T RF out with 8 non-adjacent carriers and supports 16 MPTS as mirror of 16 carriers or 8 MPTS as mirror of 8 carriers through Data2 (GE) output port. This full function device makes it ideal for small CATV head end system, and it’s a smart choice for hotel TV system, entertainment system in sports bar, hospital, apartment..
