Image caption Chvrches' singer Lauren Mayberry was the first voice to be heard on the channel

The new BBC Scotland channel has broadcast for the first time.

A specially-commissioned short film featuring Scottish band Chvrches and the BBC Scottish Symphony Orchestra opened proceedings.

Chvrches' singer Lauren Mayberry was the first voice to be heard on the channel, performing the band's song Miracle accompanied by images of Scottish people, places and landscapes.

The channel will feature hundreds of hours of newly-commissioned programmes.

BBC Scotland Director Donalda MacKinnon predicted the new television channel would be a success over time.

She told BBC Radio Scotland: "I'm certainly not fixated on a particular audience segment at this stage.

"I think it would be folly to try too hard to anticipate numbers - either low or high.

"What we're looking to achieve is success over time and I guess audience appreciation in Scotland."
