BBC on Wikipedia part 5 (Service on Televisi)
In the UK, BBC One and BBC Two are the BBC's flagship television channels. Several digital only stations are also broadcast: BBC Three, BBC Four, BBC News, BBC Parliament, and two children's channels, CBBC and CBeebies. Digital television is now in widespread use in the UK, with analogue transmission being phased out by December 2012[45].
BBC One is a regionalised TV service which provides opt-outs throughout the day for local news and other local programming. These variations are more pronounced in the BBC 'Nations', i.e. Northern Ireland, Scotland and Wales, where the presentation is mostly carried out locally on BBC One and Two. BBC Two variations within England are currently rare, though most regions still have the ability to 'opt out' of the main feed, albeit on analogue only. BBC Two was also the first channel to be transmitted on 625 lines in 1964, then carry a small-scale regular colour service from 1967. BBC One would follow in November 1969.
A new Scottish Gaelic television channel, BBC Alba, was launched in September 2008. It is also the first multi-genre channel to come entirely from Scotland with almost all of its programmes made in Scotland. The service is currently[when?] only available via satellite and cable television.
In the Republic of Ireland, Switzerland and the Netherlands, the BBC channels are available in a number of ways. In these countries digital and cable operators carry a range of BBC channels these include BBC One, BBC Two and BBC World News, although viewers in the Republic of Ireland may receive BBC services via 'overspill' from transmitters in Northern Ireland or Wales, or via 'deflectors' – transmitters in the Republic which rebroadcast broadcasts from the UK, received off-air, or from digital satellite.
From 9 June 2006, the BBC began a 6–12 month trial of high-definition television broadcasts under the name BBC HD. The corporation has been producing programmes in the format for many years, and states that it hopes to produce 100% of new programmes in HDTV by 2010.[46] On 3 November 2010, a high-definition simulcast of BBC One was launched.
Since 1975, the BBC has also provided its TV programmes to the British Forces Broadcasting Service (BFBS), allowing members of UK military serving abroad to watch and listen to them on two dedicated TV channels.
In 2008, the BBC began experimenting with live streaming of certain channels in the UK, and in November 2008, all standard BBC television channels were made available to watch online
