YouView - an internet TV service that combines the UK's Freeview channels with on-demand content - has been formally launched.

Users will have access to programmes broadcast over the previous week from the BBC, ITV, Channel 4 and Channel Five, as well as the ability to pause and rewind live TV.

Richard Halton is YouView's Chief Executive, and he gave a demonstration of the product to Rory Cellan-Jones.
