The BBC will be increasing the length of high definition (HD) broadcasts to nine hours per day.
This is a planned change to the amount of HD hours that the BBC plans to broadcast.
Currently the BBC HD service starts at around 6.20 pm and runs to midnight, unless there is a special event planned.
When the changes take place, the BBC HD broadcasts will start at around 4.00 pm and go on until 12.30 am or 1.30 am seven nights a week, although if there is a special event on, then the hours will be extended as before.
The BBC HD service is available on BSkyB for a subscription fee, while Freesat subscribers will be getting the opportunity to view more HD TV without the need for a subscription.
