Five new BBC HD channels, including CBeebies HD and CBBC HD, will go live tomorrow.
BBC Three HD, BBC Four HD and BBC News HD will also launch tomorrow, five months after the broadcaster’s original announcement.
The new channels will be available on Freeview HD, Freesat HD, YouView (from BT, TalkTalk and retailers), Sky HD and Virgin Media.
Viewers will also be able to catch up on the new HD channels using 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.
