In the United States, a multichannel video programming distributor (MVPD) is a service provider that delivers video programming services, usually for a subscription fee (pay television). These operators include direct-broadcast satellite (DBS) providers, cable television (CATV) systems, and other various wireline video providers (including Verizon FiOS as well as AT&T U-verse) and competitive local exchange carriers (CLECs) using IPTV. The corresponding term used by Canadian regulators is Broadcast distribution undertaking (BDU).〔(【引用サイトリンク】title=General Authorizations for Broadcasting Distribution Undertakings )〕 Section 602 (13) of The Communications Act of 1934 (as amended by the Telecommunications Act of 1996) defines an MVPD as a person such as, but not limited to, a cable operator, a multichannel multipoint distribution service, a direct broadcast satellite service, or a television receive-only satellite program distributor, who makes available for purchase, by subscribers or customers, multiple channels of video programming.〔(Communications Act of 1934 as Amended by the Telecommuncations Act of 1996 ), Retrieved on 2009-07-16.〕 ==Origins of cable television== (詳細はRCA then launched Satcom I, the first of several satellites allowing new services such as HBO and fledgling Atlanta-based superstation WTCG to send out their programming for hundreds of dollars per hour rather than the $3,000 per hour required to use telephone lines to transmit the services.〔 Satellites were also cheaper than microwave relay systems.〔 By 1980, 15 million of the 75–80 million U.S. homes with at least one television set had a cable television subscription, and one prediction was for that number to double by 1985. By 1981, eleven communications satellites were in use, and the Federal Communications Commission planned 24 to be in use by 1985. Most cable channels wanted space on Satcom I, since cable companies had receiving dishes aiming in that direction. In November 1981, Satcom III-R replaced Satcom I, which changed to voice and data distribution. 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「Multichannel video programming distributor」の詳細全文を読む スポンサード リンク
