Internet-based AV synchronisation in real time

Would you like your public videos to " speak " without disturbing anyone? In the language of your audience's choice? And always with perfect lip-sync?

With Nubart Sync you just found the live AV-synchronisation technology you were looking for.

Your listeners simply scan a QR code to get the soundtrack for your videos in the language of their choice. The sound will be streamed to them in perfect sync, with no delays.

Our patent pending solution is also simple and affordable. It does not require special equipment or complex technical systems such as broadcast, captive networks, beacons or infrared. All you and your audience need is a regular internet connection (WIFI or mobile data).

Nubart sync is fully scalable: suitable for any number of listeners. Looping is possible. Video length is irrelevant. Perfectly suitable for any kind of large-scale public displays, whether it be a mosaic video walls, a projected video, or a laser show.

Give sound to muted displays and transform public messaging

Why Nubart Sync?

Unlocking silent videos in public places

Public space is full of videos: video advertisements on billboards and shop windows, security information in airports, documentary videos in waiting rooms... But both security and coexistence rules require that these videos be shown in silence.

These videos could significantly reinforce their message if passers-by were able to simply stream the sound to their cell phones.

Until now, this goal could only be achieved with complex hardware systems or applications.

With Nubart Sync, sound can be added to videos in public spaces without disturbing passers-by or bystanders. Simply place our QR code next to the screen or integrate it into the video itself.

You can try it out right now with our demo: no need to enter an email address!

What is now on the market to pair audio with video?

What makes Nubart Sync better than current solutions

Current solutions

Today, high-maintenance hardware is still necessary to pair synced audio with a video: dedicated video players, RF, RFID and IR activation systems, i-Beacons, etc.

Some companies offer Wi-fi broadcasting, but subject to a captive portal, sometimes combined with a native application.

What makes Nubart Sync better

The value of Nubart Sync lies in its revolutionary simplicity.

For the first time, a multilingual, perfectly lip-synced audio source for public videos can be streamed spontaneously and easily to any passer-by via a QR code.

The synced soundtrack simply opens in the end user's browser.

What does this mean

Nubart Sync is a low cost SaaS-solution that has the potential to revolutionize the world of digital signage, DOOH, advertising and accessibility.

Our innovative product is protected by patents in key global markets.
