ABC Television is a service of the Australian Broadcasting Corporation launched in 1956. As a public service broadcaster, the ABC provides four non-commercial channels within Australia, and a partially advertising-funded satellite channel overseas. ABC is one of five main free-to-air networks in Australia. == History == (詳細はTCN-9 Sydney was the first to broadcast in Australia, soon followed by the ABC's own ABN-2 Sydney and later ABV-2 in Melbourne.〔〔 Six stations, three in Melbourne and three in Sydney, were in operation in time to cover the 1956 Summer Olympics in Melbourne.〔〔 The ABC's first television broadcast was inaugurated by Prime Minister Robert Menzies on 5 November, at the Gore Hill studios in Sydney, followed two weeks later by transmission in Melbourne.〔〔 Outside broadcasting was also initiated on 5 November, from the ABC's first outside broadcast van. The van, now in the collection of the National Museum of Australia, was instrumental in the production of thousands of outside broadcasts. It was restored in time to be displayed at the Sydney Olympic Games and was used to film the visit of Queen Elizabeth II to the site of the National Museum in 2000.〔(Morris Model FE Pye outside broadcast van used by ABC-TV Channel 2 ABN ), National Museum of Australia〕 Although radio programs could be broadcast nationally by landline, television relay facilities were not put in place until the early 1960s.〔 This meant that news bulletins had to be sent to each capital city by teleprinter, to be prepared and presented separately in each city, with filmed materials copied manually and sent to each state.〔〔 A purpose-built television studio was built in Sydney, and opened on 29 January 1958, replacing temporary sound studios used since the ABC's television services launched in 1956. In the same year, technical equipment was also moved to permanent locations, while main transmitters were introduced to Melbourne and Sydney in 1957 and 1958, respectively. Direct relays between Sydney and Melbourne, as well as Canberra, were also established in 1961, replacing temporary microwave relays as a means of simultaneously airing programs across multiple stations.〔〔(【引用サイトリンク】 publisher = Australian Broadcasting Corporation )〕 Videotape equipment, allowing the sharing of footage with much greater ease and speed, was installed in each state capital by 1962.〔 ABQ-2 Brisbane was the third ABC TV station to launch and was followed a year later by counterparts in Perth, Hobart, and Adelaide. ABC-3 Canberra opened a year later, with ABD-6 Darwin finally completing the ABC's coverage of every state in 1971. Teletext services were introduced to ABC in 1983 to allow hearing-impaired viewers access to closed captions. International television service Australia Television International was established in 1993.〔〔(【引用サイトリンク】 publisher = Australian Broadcasting Corporation ) 〕 Australia Television was sold to the Seven Network in 1998, however the service continued to show content from ABC News up until its closure in 2001.〔 The ABC's television operations joined its radio and online divisions at the Corporation's Ultimo headquarters in 2000.〔(【引用サイトリンク】 publisher = Australian Broadcasting Corporation )〕 In 2002, the ABC launched ABC Asia Pacific, the replacement for the defunct Australia Television channel operated previously by the Seven Network.〔 Much like its predecessor, and companion radio network Radio Australia, the service provided a mix of programming targeted at audiences throughout the Asia-Pacific region.〔 Funding cuts in 2003, meanwhile, led to the closure of Fly and the ABC Kid's Channel.〔 ABC2, a second attempt at a digital-only television channel, was launched on 7 March 2005, running on a budget of $3 million per year.〔 Minister for Communications Helen Coonan inaugurated the channel at Parliament House three days later. Genre restrictions limiting the types of programming the channel could carry were lifted in October 2006—ABC2 was henceforth able to carry programming classified as comedy, drama, national news, sport and entertainment. In the lead up to the 2007 federal election, the Australian Government endorsed a proposal submitted to the Australian Communications and Media Authority by the ABC to launch a second digital channel targeted at children.〔 〕 The new channel, titled ABC3 would aim to provide at least 50% Australian-made content. At midday on 8 February 2008, ABC Television was rebranded as ABC1, complementing the existing ABC2 digital-only channel launched on 7 March 2005. ABC has 4 digital services:〔(ABC Digital TV )〕 As of 2009 ABC announced an Australia wide upgrade to their Digital service, provide a 7-day Electronic Program Guide and give new logical channel numbers for all of ABC’s television services. The new ABC logical channel numbers are below. 〔http://www.abc.net.au/tv/digital/〕 These services are available nationally through digital terrestrial television, and all the digital TV services are also available through the VAST free-to-air satellite service. Only the primary ABC channel is available on the Optus Aurora satellite platform. In June 2010, playout was moved to a new facility shared with WIN Television at Ingleburn. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「ABC Television」の詳細全文を読む スポンサード リンク
