Broadcasters are considering plans to show the royal wedding in 3D.
The marriage of Prince William and Kate Middleton at Westminster Abbey is expected to draw a huge worldwide audience.
Jana Bennett, director of BBC Vision, said early meetings had taken place with other broadcasters and she was aware of
interest in using 3D technology.
"We are already planning with the other broadcasters so I know about the 3D thing as well. That is obviously of some interest but our responsibility is to bring things everybody can see on air and 3D has a very limited footprint."
There has been speculation on technology websites that Sky is considering 3D coverage of the event, but a spokeswoman said it was "speculation at this stage".
