AV to RF Converter 24 CVBS to QAM DVB-C SD Encoder Modulator with Multiplexer and Scrambler
Model : COL5184A
Outline
COL5184A AV to RF converter encoder modulator is a professional high integration device which includes encoding, multiplexing, scrambling and modulation. It supports 8/12/24 CVBS inputs, one DVB-C tuner input and 128 IP input with Data1 (GE) and Data2 (FE) port. It also supports DVB-C/T RF out with 4 adjacent carries, and support Data1 (GE) output port to support 4 MPTS out. 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…
