BBC Two Wales will launch as a HD channel later this year.
It will mean all BBC Wales content will now be available in HD.
BBC Two Wales HD will be available on Freeview HD, Youview, BBC iPlayer and other DTT HD platforms. The precise launch dates will be confirmed shortly.
BBC Cymru Wales director Rhodri Talfan Davies said the shift was an important step in the technical upgrade of BBC Wales services as it prepares to move to its new broadcast centre at Central Square in Cardiff city centre.
He said: “I am delighted that all of BBC Wales’ TV output will now be available in HD for the first time. Audiences across Wales rightly expect HD-quality broadcasts - and I’m delighted we have at last been able to confirm the switch to HD for BBC Two Wales.”
