Multi Channel H.264 Encoding 1080p Digital Rf Encoder With Dvb-c Isdb-t Dvb-t Atsc Modulation Encoder Modulator COL5181HM
Product Overview
COL5181HM is a professional high integration device which includes encoding, multiplexing, and modulation. It supports 8/16/24 HD'MI inputs, 1 ASI input, 1 USB payer input and 128 IP inputs via the GE port. It also supports DVB-C RF out with 12 non-adjacent carries or DVB-T/ATSC RF out with 8 non-adjacent carriers, or ISDB-T RF out with 6/16 non-adjacent carriers, and supports 12/8/6/16 MPTS as mirror of 12/8/6/16 carriers through the GE port and 1 ASI out as mirror of one of the carriers. 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, apartmentt etc.
