Product Overview
3544HA SD encoder modulator is a professional high integration device which includes encoding, multiplexing, scrambling and modulation. It supports 24 CVBS inputs with MPEG-2 video encoding and MPEG-1 Layer 2, DD AC3 (2.0) audio encoding and one DVB-C (ATSC optional) tuner input and 256 IP input through 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…
