Distribution of content in High Definition

HDShare allows the distribution of high definition content, up to 1080p, throughout the house, collective antenna, commercial or residential buildings, University Campus, Hotels, Hospitals, Military Installations, Digital Signage, etc.


  • See the signal from a satellite TV receiver on all the TVs in the home.
  • Watch movies from a multi-media player on any TV.

  • See movies, photos, etc. from your Apple TV, Chromecast, Amazon Fire, Filmin, Wuaki, Roku, etc. in all the
  • Televisions of the installation.

The professional modulation specifications, with a MER greater than 38 dB, offer you an exceptional quality and without cuts no matter how extensive the installation is.

The signal from the RF output can be combined with the terrestrial TV signal and distributed by the same coaxial cable through which the TVs already receive the DTT channels.

Does not require additional wiring.

Is your installation especially difficult?

If you have several signal sources with different resolutions, unknown, or that start without a fixed resolution, or have modern and first generation (720p) HD TVs in the rooms ... do not worry.
HDShare comes to the rescue.

Multi-Language Web Configuration

Configuration and monitoring of all modulator parameters, locally or remotely, with the integrated web server. Automatic IP address with DHCP.

It allows saving different configurations in files of your computer, for later use.

* Of course you can also configure the modulator with the keyboard and display on the front panel.

A Solution for difficult cases

Of course, you want the best quality 1080p HD signal on each TV.

No problem! HDShare encodes and modulates the HDMI signal up to 1080p 60fps resolution in fully transparent mode.

Simply connect your HDMI signal source up to 1080p resolution to the HDMI input connector, and all TVs will receive it in the original resolution.

But in some situations things are not so easy ... until now.

Instead of having a signal source with a stable resolution, your client can have several video signal sources with different resolutions (eg a bluray at 1080p, a TVSAT receiver at 1080i and an IPTV streamer at 720p) connected to An HDMI switch, or perhaps its signal source has the "bad habit" of booting with a different resolution every time it is started.

As a professional installer you already know that this can be a nightmare. Each of the televisions in the installation is waiting for the original resolution it found when it searched and memorized the channel. Most televisions will not show the video, if the resolution is different from the one memorized.

In the installation coexist modern televisions that accept HD 1080p with televisions that accept at most a resolution of 1080i, by the antenna input.

HDShare solves both root problems with exclusive functionality. Simply click on the "Scale to 720p" box in the web configuration and the HDShare will ensure a stable 720p HD resolution regardless of any change in the resolution of the input signal.

On the main TV, connected to the HDMI output of the modulator, you will continue to enjoy the original quality and resolution.
