DirecTV-14 is a communication satellite launched on December 6, 2014.〔(Arianespace to launch up to four satellites for DirecTV )〕 It is the first satellite offering Ultra-HD 4K television services using Reverse DBS.〔(Arianespace VA221 launches satellites for the United States and India )〕 ==Overview== The DirecTV-14 satellite is the sixth satellite built by SSL (Space Systems/Loral) for operator DirecTV. The high-capacity spacecraft is based on the SSL 1300 platform, DirecTV-14 is a 20-kilowatt class Ka-band and reverse-band digital broadcast satellite that will be used to deliver Ultra HD and other new consumer services for DirecTV. DirecTV-14 delivers hundreds of channels of digital programming to more than 31 million customers in the U.S. and Latin America with small-diameter dish antennas. This satellite will provide service for users across the U.S. (including Hawaii and Alaska) and Puerto Rico. The satellite had a liftoff mass of approximately 6,300 kg. DirecTV-14 is expected to operate for 15 years.〔http://www.spaceflightinsider.com/missions/commercial/arianespace-ready-for-final-ariane-5-flight-of-2014-with-directv-14-and-gsat-16/〕 Michael White, chairman, president and CEO of DirecTV, has been skeptical of the prospects for 4K in the past but is determined to stay on the bleeding edge of broadcast technologies. The 6,300 kg DirecTV 14 satellite will use Ka-band and Reverse Band Direct Broadcast Satellite (DBS) spectrum. DBS is expected to provide ample room for delivering 4K programs and other advanced services to customers. Last month, DirecTV became the first multi-channel video provider to offer 4K Ultra HD programming direct to customers’ TVs, offering a variety of new releases, popular films and nature documentaries with nearly four times the resolution of HD. Customers who have DirecTV’s Genie HD DVR are able to watch 4K programming on supporting 2014 Samsung UHD TVs.〔http://www.marketwatch.com/story/4k-ultra-hd-gets-a-lift-with-successful-directv-satellite-launch-2014-12-06〕 “The total addressable market for sports and movies is just always going to be bigger than the average television show because you can broadcast these worldwide and the audience will enjoy it,” says Blain Curcio, analyst at NSR told Via Satellite earlier this year. DirecTV 14 will also bolster DirecTV’s HD broadcasts. With the new satellite, the company now has a fleet of six HD satellites. Located at 99 degrees west, DirecTV 14 will use spot beams to provide more local HD content. The 20-kilowatt satellite is expected to enter service early second quarter next year. The next satellite, DirecTV 15, is scheduled to launch next year as well.〔http://www.satellitetoday.com/regional/2014/12/08/arianespace-launch-boosts-directv-on-4k-isro-on-domestic-capacity/〕 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「DirecTV-14」の詳細全文を読む スポンサード リンク
