HD Encoder Modulator
Description:
EM24 is a professional high integration device which includes encoding (and de-modulation), multiplexing, and modulation functions in one case. It supports 8/16/24 HDMI (or HDMI plus DVB-S2/S2X/C/T/T2/ISDB-T tuner mix input) inputs, 1 ASI input, 1 USB player input and 128 IP inputs via the GE port, and output by multiple DVB-C (or DVB-T/ATSC/ISDB-T optional) carrier channels. It also supports MPTS output as mirror of 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, apartment
Specification:
| Input | 8/16/24 HDMI inputs for option (or HDMI and different Tuner mix input, details pls check below order guide)
