Encoder-Modulators
HDM-9400
All-in-one HDMI encoder-modulator for DVB-C/-T head-end channels
Turn up to 24 HDMI sources into a professional DVB-C/-T channel bouquet with a single unit — encoding, multiplexing and modulation without extra equipment.
Overview
The VIZOBOX HDM-9400 is an all-in-one encoder-modulator that converts HDMI inputs into adjacent DVB-C/-T RF channels, integrating H.264/AVC encoding, multiplexing and modulation in a single unit. Available with 8, 16 or 24 HDMI inputs, it also accepts ASI, USB player and up to 128 IP streams (UDP/RTP) for re-multiplexing. Comprehensive PSI/SI editing, PID remapping and web-based management make it a reliable backbone for hotel, hospitality and distribution head-ends.
