The BBC has suggested that the 3D home cinema experience could only be a fleeting fad and that its current popularity could be detrimental to HD.

The corporation's head of HD, Danielle Nagler, outlined their reservations on the technology at the IPTV World Forum in London this week. She said they were excited about the developments being made – which are swiftly being incorporated into home cinemas around the nation with the increasing numbers of 3D-ready televisions and projectors – but needed to be cautious.

"We need to see what the long term benefits of 3D to broadcasters is, before we commit," she explained

"We are not clear on what makes good 3D and are certainly not clear on what makes good 3D television. The trials we are doing are a bit like early colour – it looks interesting but there is a long way to go."

She explained that the BBC's current focus was explaining and demonstrating HD technology to their audiences and that throwing 3D in to the mix would be distracting all round. Plans for a dedicated 3D channel are not even remotely on the horizon, rather they would show a variety of 3D content over the next few years to see what the response is like.

They have already made a small number of projects using the technology, with the box office hit, Street Dance 3D, a BBC Films project, and plans to screen rugby from the O2 arena in 3D, as well as some natural history content. There will also be precise documenting of the London Olympics conducted in 3D.
