It's a big week of football next week, as Manchester United take on FC Barcelona in the UEFA Champions League final on Wednesday 27th May, and then Everton play Chelsea in the FA Cup final on Saturday 30th May.

Both games will be available exclusively in high definition on the ITV HD channel, currently only readily available on the Freesat platform.

Sky has filmed Usain Bolt running on a specially-designed 150 metre track using five 3D camera rigs and a total of ten HD cameras.

For the first time ever, one rig was mounted on a rail cam and tracked Usain's movement, stride by stride, along the whole of the track's length.

Brian Lenz, Sky's Head of Product Design and Innovation, said, "It's great for Sky to be involved in capturing another compelling piece of content in 3D, to add to the catalogue of events we've recorded so far - from Ricky Hatton's Manchester Homecoming fight last May to a live 3D broadcast of Keane last month, and even the UK's first 3D ballet. As part of our on-going research and development work, we're continuing to assess how 3D can work across a range of events and programming genres."

The footage will be shown in Odeon cinemas later this year.

Ahh, a four-day weekend beckons. Here's a look at some of the high definition highlights available across the UK channels this weekend.

Don't forget, you need Freesat in order to watch ITV HD, and either Sky or Freesat to watch BBC HD or Channel 4 HD.
