All UK broadcasters now take delivery of their HD shows as AVC Intra 100Mbs MXF-wrapped files in the DPP AS11 format. Of course they may then be transcoded to another format for TX server playout - though I'd have thought there was a lot of sense in keeping to the same codec and avoiding this, given AVCi100 is a sensible codec at a sensible bitrate.
Tape has long since departed from the mainstream production process for mainstream broadcasters. The BBC stopped accepting TX masters on HD Cam SR a good few years ago, and BBC Information and Archives will now only accept recordings of live shows as files too.
(Live shows have what's known as a PasB - Programmes as Broadcast - recordings in an AS11 DPP-like format - the only difference being PasBs should have time-of-day timecode, not start at 10 o'clock like delivered shows. In some other areas these are sometimes called RoTs - Recording of Transmission - but PasB is the preferred term. Confusingly the BBC also have PasCs - Programme as Completed - which is the name for the production paperwork detailing the contractual status of all contributors, archive, stills, music, writers, directors, producers etc. for rights reasons)
