BBC Antiques RoadshowAudio Watermarks For Precise Time Sync

The BBC was one of the first major broadcasters to use Intrasonics audio watermarking technology to transform the viewing experience, with the launch of the Antiques Roadshow Valuation Game app and the first transmission of a watermarked episode in January 2013.

The app enabled the programme’s audience of millions to play along with the show and compete with each other using their mobile devices, by guessing the correct valuations of antiques before the expert answers were revealed on TV. At the end of each show, viewers playing along at home received a final score and discover how much they really know.

Three factors contributed to the popularity and success of the playalong app. Firstly, the app was actively promoted by show’s presenters at the start of each Antiques Roadshow episode.

Secondly, the design of the gameplay itself was such that viewers only needed to shift their attention to the smartphone or tablet screen for the few seconds it took to pick one of the four possible valuations for each item.

And, thirdly, because of the sophisticated use of Intrasonics time sync watermarks, viewers could join the show late or install the app in the first few minutes of the show but still achieve a perfect time sync and playalong experience.

We wanted our first live and synchronous companion experience to appeal to a mainstream audience and create a real event in the living room for families across the UK – the Antiques Roadshow mobile app does just that.

The new app is great fun, I love guessing the values of objects, I only wish I got it right more often! Now that you can play on smart phones and tablets, the world of antiques is certainly not stuck in the past.
