4x HDMI in 2x DVB-C / DVB-T modulator
The modulator module SPM-H4TCT converts four HDMI signals into two DVB-C or DVB-T channels.
With the four HDMI inputs, four signals of digital receivers, DVD players or other HDMI sources can be processed and fed into the network with a single module. The changeable type of modulation allows the distribution of the output signals via cable (DVB-C / QAM) or terrestrial networks (DVB-T / COFDM).
In a single base unit SPM 2.000 up to six modules (up to 24 HDMI inputs), in a single base unit SPM 200 two modules (8 HDMI inputs) can be run.
- four HDMI inputs
- MPEG4 video format
- output signal can be selected: DVB-C (QAM), DVB-T (COFDM)
- output channels can be selected between 112–862 MHz
- suitable for adjacent channel operation (forced adjacent channels)
- level attenuation 0–12 dB
- PID handling
- logical channel numbering (LCN)
- network information table (NIT)
- up to 6 modules in a SPM 2.000 (24 HDMI inputs)
- 2 modules in a SPM 200 as ultra compact headend with 8 HDMI inputs
