Seven HD was an Australian television channel, owned by the Seven Media Group, that launched on 15 October 2007.〔 The channel was available to high definition digital television viewers in metropolitan areas, Tasmania and Regional Queensland through a number of owned-and-operated stations, as well as via Prime HD and Southern Cross Television. On 25 September 2010, Seven HD was replaced by the new channel 7mate. Following the government's decision to remove the SD Primary Channel limitations, the channel will return as an HD simulcast on channel 70 in March 2016, in time for the 2016 AFL Premiership Season. ==History== Seven HD was officially announced on 15 September 2007, with the Seven Media Group announcing their intention to start a high definition multichannel, that was initially expected to launch in December 2007.〔 〕 However, Seven HD became the first Free-to-air commercial television channel introduced to metropolitan areas since 1988, when it launched prior on 15 October 2007, with ''25th Hour'' being the first program broadcast at 10:30pm.〔 〕 The channel replaced the Seven Network's existing high definition service, a simulcast of its standard definition and analogue services, known and branded as '7 HD Digital'. Due to an amendment of the ''Broadcasting Services Act 1992'' in 2006, the ''Broadcasting Legislation Amendment (Digital television) Act 2006'', television networks are now permitted to launch digital multichannels, provided that they are broadcast exclusively in high definition.〔 〕 The channel expanded its broadcast schedule on 10 December 2007 to include daytime programming which had previously been a full simulcast of the main channel. Seven HD breakaway programming ceased transmission on Sunday 4 October 2009 in preparation for the launch of 7TWO a few weeks later on 1 November. Seven HD then returned to being a high definition simulcast of Seven, before finally being replaced by 7mate on 25 September 2010. 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「Seven HD」の詳細全文を読む スポンサード リンク
