The BBC is planning to cut 2,000 jobs and radically change programming in order to cut 20% from its budget over the next five years.
No channels will close but some money will be reinvested in new programmes.
All new daytime programming will shift to BBC One, with BBC Two broadcasting repeats of peak-time programmes.
Director General Mark Thompson unveiled details of the cuts - branded Delivering Quality First (DQF) - in an address to staff on Thursday morning.
Thompson said the changes would lead to "a smaller, radically reshaped BBC".
As well as the loss of 2,000 posts across the BBC over the next five years, another 1,000 staff will relocate from London to Salford. BBC Three will move Salford in 2016.
BBC One, which is having its overall budget cut by 3%, will see a reduction in entertainment programmes "which have a lower impact", Thompson said.
There will be fewer chat shows and panel shows on BBC Two, and digital channels BBC Three and Four will become feeder channels for BBC One and Two respectively.
