HDShare HD TV home distribution

HD Multimedia distribution within your home or multi-storey building.

Up to 1080p HD video and audio is sent through your home RF coaxial network to all TV sets in your home or Multi-storey Buildings, University Campus, Healthcare, Hospitality, Military installations, Digital Signage, etc.
HDShare RF output signal is easily combined with off-air digital TV programs.

Typical applications:

  • Watch satellite TV programs in each home TV set, using a single receiver.
  • Watch HD films from your multimedia player in any or all your TV sets.
  • Place that noisy Home Theatre PC in another room, and enjoy true silence in your preferred sofa.
  • Watch your Apple TV, Chromecast, Amazon Fire or Roku streamer films, pictures, etc. across you home.

With a high quality modulator and MER better than 38 dB, the HDShare ensures no signal drop, not only in the most demanding in-house installations but also in MATV/CATV installations.

The signal is combined with the off-air digital TV antenna signal and distributed using the same coaxial cables which already reach each of your home TVs.
No additional cabling is required.

Is your installation specially difficult?

If you have multiple signal sources with different, unknown, or changing resolutions, or new and old (720p) HD TVs in your home... no worries.
HDShare comes to your aid. Look at 'For Difficult Installations' tab for details.

A Solution for difficult situations

Of course you want the best full HD signal resolution.

No problem! the HDShare is ready to encode and modulate up to 1080p and 60fps in fully transparent mode.

Just connect your 1080p signal source to the HDMI input and you HD TV sets will receive it in 1080p. No worries.

But some times you may be facing a situation with a difficult solution (until now).

  • Instead of having a video signal source with a stable output resolution, your customer may have several video signal sources of different resolutions connected to an HDMI matrix switch (ex. a 1080p bluray, a 1080i TVSAT receiver and a 720p IPTV streamer), or may be your video signal source has the 'bad habit' of choosing itself the output resolution after each power OFF / power ON.

    As a professional installer, you know this may be a nightmare. The TV sets around the home are expecting the original resolution found on the channel search and do not show the video if the resolution is different.

  • Across the installation, there are TVs accepting a maximum resolution of 1080i from the tuner input. The HDShare ensures that any content will be available in all the TV sets.

The HDShare comes in your aid with this exclusive feature. Just click on the "Scale Down to 720p" option on the web set-up and the HDShare will ensure a stable HD 720p resolution regarless any change on the input video resolution.

In the main Televisor, connected to the modulator HDMI output connector, you will continue enjoying the original quality and resolution.
