Subscribers to Sky's broadband TV bundles are being invited to join the 'Supertelly' revolution.

The broadband provider has announced that the Sky+ box set is being discontinued as a standalone product, with a new high definition (HD) version arriving in its place.

When signing up to a Sky broadband and TV package, customers will be provided with a Sky+ HD box.

A spokesperson for Sky stated: "We are all really excited about this move here at Sky as we all believe that HD is going to grow significantly in 2010.

"HD is a much better viewing experience than standard definition, especially when watching live sport."

The Sky+ service is continuing unaffected, but the announcement means all new satellite viewers will have the option of high-definition viewing.

Last month, the firm announced it would be launching its own 3D channel in April 2010.

The service, which will be available through the Sky+ HD box, will initially only be available to public houses.
