The BBC is kick starting its companion screen plans with an application for PC, tablets, mobile phones and the BBC Red Button that will allow fans of Antiques Roadshow to play along with the programme when it returns to the screen in September.

Announced by Victoria Jaye, the corporation's head of IPTV and TV Online Content, during the Connected TV Summit in London, the app will allow viewers to guess the value of antiques before the experts reveal their estimations. It will work with both the live broadcast and when it is played through on-demand catch up TV - presumably via BBC iPlayer.

The companion experience will also include information on featured antiques shown on the Antiques Roadshow, with a stack of extra content created by the show's experts and BBC production team.

More companion, second-screen applications are planned as part of a wider strategy, and it has been revealed that the BBC has been running closed trials with Frozen Planet and Secret Fortune, both of which are now completed.

"Antiques Roadshow is a perfect series to develop a companion experience around," said Jaye.

"We’re tapping into existing audience behaviour - viewers have been shouting at their TV screens for years, guessing the value of items featured in the programme. We’re also taking viewers on a journey beyond where the broadcast programme can go, providing in-depth content about the stories and the history behind featured antiques in the programme, drawn from across BBC Online and other trusted sources.

"It’s a great example of how we can creatively renew our audiences’ enjoyment of watching a much cherished BBC programme."

The applications will be free to download and use.

We also suspect that the iOS app will definitely work on the first iPad, it being an antique itself.
