Although AS-11 files have been the preferred delivery method since 2014, some programmes, including those delivered close to transmission, are still provided on tape.

“The introduction three years ago of standardised file delivery has been a huge success,” said DPP managing director Mark Harrison.

“Today’s announcement completes that journey by clarifying there will now only be one UK delivery format: AS-11 DPP.

“By choosing a date that is nearly a year away, everyone has the time to plan for the end of the use of tape.”

Acquired and repeated programming may still be delivered as tape, by agreement, the DPP added.

Standardised file delivery began back in October 2014, when all UK broadcasters adopted a common specification established by the DPP.
