WS-8901U R86201 digital modulator is a multipurpose device that converts HDMI or baseband A/V signal into DVB-T COFDM multiplex (with single channel). The device can effectively distribute high definition signal (H.264 video compression, bit rate up to 20 Mbps). Additional RF input (ANT IN) can be used for combining the output RF signal with other TV signals.
The source signal may come from a multimedia player, DVR, Blu-ray player, PC, STB etc. The modulator can distribute high quality content in the form of DVB-T multiplex via typical RF coaxial cables used in antenna and CCTV systems.
RF modulators are not used only in antenna systems (MATV/SMATV). Sometimes, the distribution of signal A/V signals via coaxial cable (after conversion to RF signal) is much simpler and less expensive than other solutions - especially in situations where the signal has to reach multiple points (receivers). An example is an electronics store, where an HDMI -> DVB-T modulator eliminates the problems with splitters and tens of HDMI cables that could be used for the distribution of the demonstration content to tens of televisions.
Key features
  • Digital modulator HDMI-DVB-T,
  • Possibility to connect any HDMI signal source and then modulate it into a digital DVB-T multiplex,
  • Compression with H.264 codec and a maximum bitrate of 20 Mbps,
  • Conversion of signal from any HDMI source,
  • High quality digital signal of HD standard,
  • Ideal for SMATV systems, hotels, TV stores, galleries, pubs, etc.,
