EchoStar Corporation is a global satellite services provider and developer of hybrid video delivery technologies. EchoStar is the owner and operator of the satellite fleet for closely affiliated Dish Network. The company also designs and manufactures set-top boxes to receive the Freeview broadcasts in the United Kingdom, as well as receivers for Bell TV in Canada. EchoStar also owns Sling Media, which designs and builds the Slingbox TV streaming device, and satellite internet provider Hughes Communications. Prior to 2008, EchoStar operated the Dish Network service brand; the Dish Network brand was spun off as Dish Network Corporation on January 1, 2008. ==History== EchoStar was originally formed in 1980 by its chairman Charles Ergen as a distributor of C band TV systems. In 1987, EchoStar applied for a direct broadcast satellite (DBS) license with the Federal Communications Commission and was granted access to orbital slot 119° west longitude in 1992. On December 28, 1995, EchoStar successfully launched its first satellite, EchoStar I. On March 4, 1996, EchoStar established the Dish Network brand name to market its home satellite TV system. In 1998, EchoStar purchased the broadcasting assets of a satellite broadcasting joint venture of News Corporation's ASkyB and MCI Worldcom. With this purchase EchoStar obtained 28 of the 32 transponder licenses in the 110° W orbital slot, more than doubling existing CONUS broadcasting capacity at a value of $682.5 million. The acquisition inspired the company to introduce a multi-satellite system called DISH 500, theoretically capable of receiving more than 500 channels on one dish. "Legacy" represent the 950 to 1450 MHz frequencies used to deliver the signal throughout the home; the signal is broadcast to the home on the Ku band from satellite (12.2-12.7 GHz). Ku frequencies will not work on home wiring, the signal is downconverted to the intermediate frequency (IF) of 950-1450 MHz at the dish antenna. Newer technology (DishPro) also uses 1650-2150 MHz in addition to 950-1450. Also in 1998, EchoStar - in association with Bell Canada - launched Bell TV. On September 25, 2007, EchoStar announced it had agreed to acquire Sling Media, Inc. On January 2, 2008, the Dish Network business was demerged from the technology and infrastructure side of the business. A split in the shares created two companies, DISH Network Corporation which consists mainly of the DISH Network business, and EchoStar Corporation which retains ownership of the technology side including the satellites, Sling Media, and the set-top box development arm. On February 14, 2011, EchoStar announced that it would acquire Hughes Communications in a deal valued at US$1.3 billion. 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「EchoStar」の詳細全文を読む スポンサード リンク
