ABN is the Australian Broadcasting Corporation's television station in Sydney. The station began broadcasting on 5 November 1956. Its original studios were located in Gore Hill, New South Wales and were in use up until March 2004, when they were co-located with ABC Radio, Radio Australia and Australia Network at the Corporation's headquarters in the inter-city suburb of Ultimo, New South Wales.〔''Media Room – Inside the ABC – Issue 7''.

For more than 40 years, Gore Hill was best known as the location of the ABC's Sydney television studios, which were fully opened in 1958 and which operated until 2002, when the site was closed and sold off. Later, the ABC moved its television operations to its broadcasting centre in Ultimo. ABN Sydney shares its digital broadcast centre facilities with Sydney's community television station TVS. The station has also previously carried a number of programs originally produced at other Channel 31 stations in other states (programs such as Aurora Community Channel & National Indigenous Television). ABN commenced digital television transmission in January 2001, broadcasting on VHF Channel 12 while maintaining analogue transmission on VHF Channel 2. The analogue signal for ABN was shut off at 9.00am AEDST, Tuesday, 3 December 2013. 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「ABN (TV station)」の詳細全文を読む スポンサード リンク
