BBC brings HD to the iPlayer

Users will be able to stream HD programmes for seven days after first broadcast, or download and watch them within 30 days.

BBC HD is available on satellite and cable and features a range of programmes from across other BBC TV channels, including 'Doctor Who', 'Dragons' Den' and children's show 'Kerwhizz'.

HD TV has up to five times more detail than standard definition television, providing vivid colours and crisp pictures.

Alongside the introduction of BBC HD programmes on the iPlayer, higher quality streams are also available from today within a new resizable media player.

The BBC said users will be able to select a large playback window size, featuring video streams that are nearly twice as good as the previous High Quality format.

Danielle Nagler, head of BBC HD, said: "It's great that we've been able to bring the BBC HD channel to the BBC iPlayer family.

"In the last month we've extended the channel hours to nine per day, refreshed the look, enhanced the range of programmes, and now our HD content will be available whenever and wherever audiences want it.

"We're seeing huge demand for HD content and I'm confident that this will help ensure it is as accessible as possible."

Other features unveiled today include an internet speed diagnostics page and the full release of the BBC iPlayer Desktop, which allows Windows, Mac and Linux users to download BBC programmes, including those in HD.

Anthony Rose, controller, BBC FM&T Vision & Online Media Group, said: "Introducing BBC HD and other higher quality streams enables users to enjoy BBC programmes in HD without a set-top box, and also marks a significant milestone in boosting video quality over BBC iPlayer."
