WS-7990 R86704 modulator is a multipurpose device that converts four HDMI or baseband A/V signals into four DVB-T multiplexes (channels). The signals can have resolutions from SD to Full HD, and can be provided to 4x HDMI or 4x A/V (RCA - SD only) inputs. Additional RF (ANT IN) input can be used for combining the output RF signal with other TV signals.
The device has four audio/video channels (four HDMI inputs or alternatively four sets of A/V inputs for connecting four independent signal sources). The output DVB-T RF channels (multiplexes) can be combined with any DVB-T signals distributed in an existing MATV/SMATV system in a multi-dwelling unit, hotel, hospital, shopping mall etc.
The source signals may come from multimedia players, DVRs, Blu-ray players, PCs, STBs etc. The modulator can distribute high quality content in the form of DVB-T channels via typical RF coaxial cables used in antenna and CCTV systems. The maximum bit rate is limited by the DVB-T standard (31.68 Mbps), whereas the maximum bit rate of a video stream cannot exceed 18.0 Mbps.
All parameters are set with buttons and shown by the display located on the front panel of the modulator.
