HD gives you exceptionally clear, crisp pictures with vivid colours and up to five times more detail than standard definition.
Programmes made in HD can provide the best possible quality pictures on current equipment. Only a high definition television, high definition digital box and high definition broadcast used together provide high definition viewing.
The BBC has launched five new High Definition services (BBC News HD, BBC Three HD, BBC Four HD, CBBC HD and CBeebies HD). These services will be available on Freeview HD, Youview, Virgin Media, Freesat and Sky HD.
The BBC also has BBC One HD, and BBC Two HD, and brings the total number of subscription-free HD channels from the BBC to seven.
Viewers will also be able to catch-up on HD programmes from these channels on BBC iPlayer.
