CBeebies HD and CBBC HD are two of five new subscription-free HD channels set to be launched by the BBC tomorrow.

BBC Three HD, BBC Four HD and BBC News HD are the other channels going live, five months after the original announcement.

The new channels will be available on Freeview HD, Freesat HD, YouView (from BT, TalkTalk and retailers), Sky HD and Virgin Media, and viewers will also be able to catch up on HD programmes from these channels on BBC iPlayer.

Tony Hall, BBC Director-General, said: “I am delighted that we’re able to launch our new HD channels in time for Christmas, when families gather together to enjoy some of the best TV from the BBC. This year, people will be able to watch even more of our programmes in brilliant quality.”

All five new HD channels will broadcast the same programmes as their standard definition equivalents in HD.

The corporation launched BBC One HD in 2010 and in the past 15 months has added BBC One Scotland HD, BBC One Wales HD, BBC One Northern Ireland HD and BBC Two HD.
