翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Radio jamming in China ： ウィキペディア英語版 Radio jamming in China Radio jamming in China is a form of media censorship that involves deliberate attempts by state or Communist Party organs to interfere with radio broadcasts. In most instances, radio jamming targets foreign broadcasters, including (but not limited to) Voice of America, Radio Free Asia and the BBC World Service, as well as stations based in Taiwan. ==Methods== Radio jamming is achieved by transmitting radio signals on the same frequency as the intended target. The government of the People's Republic of China disrupts shortwave radio communications through this method, typically by broadcasting music, drumming, or other noise.〔Doug Mellgren, ('Tibet exile radio says China jamming it' ), Associated Press, 2 April 2008.〕 On shortwave, the jamming sound is composed of Chinese folk music, specifically a composition known as ''The Firedrake'', running about 1 hour in duration. The 60 min audio clip is broadcast over spread spectrum throughout almost the entire shortwave radio band. It is being streamed though the "Sat 6B" that was launched in 2007. There are also Highquality recordings (mono) existing on the internet. 〔('Firedrake - The source of China's Radio Jammer found on Chinasat 6B' )〕 The French defense electronics company Thales Group has been accused of aiding Chinese censorship efforts by selling shortwave broadcasting equipment to Chinese authorities. The firm has responded that the sale of equipment was intended for civil purposes.〔Amy Kraft, (Thales denies selling radio jamming kit to China ), Reuters, 31 March 2008.〕 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「Radio jamming in China」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
