Professional HD Modulator With ATSC DVB-T DMBT ISDB-T TV Channel Output
This professional HDMI to RF modulator is designed for converting HDMI video played from computer, blu-ray player, set top box or HD security camera to a digital TV channel of user choice for broadcasting and distribution.

This HD modulator is an universal RF modulator for worldwide digital TV system. It supports modulation into terrestrial digital TV channel frequencies for ATSC, DVB-T, DVB-C, DMBT and ISDB-T TV signals.

Its programmable TV channel selection allows users to select any desired TV channel frequency for its RF output.

This HD modulator can be used as a standalone unit or multiple modulators chained together for creating more private digital TV channels. No coax combiner needed.

Ideal and cost effective tool for creating your own advertising or information TV channel through using this HD modulator. 

Or simply distributing 720p or 1080p HDMI video to all HDTV sets connected through the same coax cable for large-scale TV distribution applications such as:

  • home entertainment
  • educational training
  • security surveillance
  • commercial advertisement/digital signage
  • information display
  • emergency messaging announcement
  • private MATV system

HDMI Input + RF Input + Closed Caption Input
This unit is built with 1 HDMI input, 1 RF input, 1 closed caption input with 1 RF coax output. 

Any HDMI signal from devices such as satellite receivers, computer, HD player or HD surveillance camera can be modulated by this device into an aerial HDTV channel of user's selection. [Note: most of the HD surveillance cameras use different HD format for output. So additional converter will be needed before feeding into this modulator]

This HD modulator can also accept closed caption signal from its RCA input and encode them into its RF output.

Its RF input allows this modulator to accept RF output from another HD modulator, antenna or set top box and combine with its own modulated channel into one coax TV signal.

Easy Web GUI Operation
This universal HD modulator is easily configured.
Users can access and control the HD modulator through using a web browser when directly connected with a PC using Ethernet cable. 

Its web control panel provides all the detailed control functions such as DTV system selection (ATSC, DVB-T, DVB-C, DMBT, ISDB-T), TV channel frequency, channel name and so on.

Universal Modulation Into Worldwide Digital Terrestrial TV Signal
This HD Modulator supports selectable modulation into world-wide terrestrial TV channel frequency for ATSC, DVB-T, DVB-C, DMBT and  ISDB-T TV signals.

After the cabling hookup and TV channel output setup, users could use the TV remote or IR remote of the digital aerial TV receiver box to tune into the new channels just created and see their HD video or camera screen showing on the HDTV screen.

MPEG2 Video Encoding With AC3 Audio Encoding
This HDMI to RF digital modulator adopts MPEG2 for HD video encoding. The output RF TV signal quality will follow the original HDMI input quality. Maximum modulation quality up to 1080p.

The unit also supports MPEG1 digital audio AC3, AAC and PCM audio encoding into digital RF output.

Daisy Chain Setup For Producing Multiple HD TV Channels
This digital HDMI modulator can be used as a standalone unit or cascading with other units together.

Multiple of these digital modulators can be linked together by feeding the modulated RF output from the first unit into the RF input of the next HD modulator so more private digital TV channels can be created and combined together in one RF output for large-scale HDTV distribution.

Easy HDTV Distribution
Users can also use RF coax splitters to distribute the modulated coax feed to multiple TV displays

Users can also add more of these RF modulators for modulating more HD videos into more digital TV channels and combined them in one coax cable run or using the daisy chain hookup for cascading as described earlier for large-scale private TV channel distribution.

HDMI Extension Over Coax Cable
This HDMI to RF modulator can also be combined with our digital TV tuner box, model DTV103, so they can be used as a HDMI video/audio over coax cable extender kit for HD content distribution purpose.

Typical uses of this HD type digital RF modulator including:

  • DIY CCTV Surveillance: video from surveillance camera or CCTV DVR can be modulated into new private digital TV channel. So users can simply view the live camera feed on the TV by tuning into the custom TV channel for review or recording. [Note: most of the HD surveillance cameras use different HD format for output. So additional converter will be needed before feeding into this modulator]
  • Education/Training: build private TV channels for broadcasting the computer screen or digital media content prepared by teacher or instructor for classrooms. Any TV connected in the same coax cable can watch the custom-made TV channel created by using this HD RF modulator.
  • Digital Signage: converting digital media content played from DVD player or any digital media player into a commercial TV channel and transmitted over multiple TV displays in public place for advertisement or signage purpose.
  • Retail Store Advertising: retail store owners can use TVs to play their own video ads on TVs through single coax cable run inside the retail store. No internet or network connection needed.

Powerful 100db Output For Long Range Transmission
This RF modulator is featured with a powerful 100dB output, which is sufficient for long cable transmission up to 1200 meters with no loss of picture and sound.

Analog video/audio signals transmitted over existing coax cable with such high dB strength can offers far longer distance than the typical balun or Cat5 extender solution.
