翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク CGMS-A ： ウィキペディア英語版 CGMS-A Copy Generation Management System - Analog (CGMS-A) is a copy protection mechanism for analog television signals. It consists of a waveform inserted into the non-picture Vertical Blanking Interval (VBI) of an analogue video signal. If a compatible recording device (for example, a DVD recorder) detects this waveform, it may block or restrict recording of the video content. It is not the same as the broadcast flag, which is designed for use in digital television signals, although the concept is the same.〔(Techdirt: Microsoft: It's Not The Broadcast Flag, It's A Different Flag )〕 There is a digital form of CGMS specified as CGMS-D which is required by the DTCP ("5C") protection standard. == History == CGMS-A has been in existence since 1995, and has been standardized by various organizations including the IEC and EIA/CEA. It is used in devices such as PVRs/DVRs, DVD players and recorders, D-VHS, and Blu-ray recorders, as well certain television broadcasts. More recent TiVo firmwares comply with CGMS-A signals. 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「CGMS-A」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.
