Freeview has officially launched its high definition (HD) service.
Freeview HD currently offers three HD channels: the BBC HD channel, ITV1 HD and Channel 4 HD.
Freeview said the service, which initially began broadcasting on December 2 last year, will be rolled out to 4.5 million new homes, ensuring that 50 percent of the UK had access to the service in time for the World Cup, which begins on June 11 and will be shown on both the BBC and ITV HD channels.
Viewers will need a set-top box that can accept the Freeview HD signal to access the service.
"High definition television comes of age today with the launch of the new HD service from Freeview, the UK's most popular digital TV platform," Freeview said.
"Millions of TV lovers will benefit from free HD channels without installation, offering the quality viewers have come to expect from HD - up to five times more detail than standard definition and the possibility of stunning 5.1 surround sound."
