CNN Pipeline was an English language video news service providing both live and on-demand video to subscribers' computers via broadband Internet connections. It was part of the CNN group of news services. The service was subscription-based, and did not contain advertising like other CNN stations. Pipeline was made available to the public on December 5, 2005, after years of planning and months of internal testing. The bandwidth, storage and streaming servers was provided by AOL, which is also owned by Time Warner. Each of the feeds broadcast in the 16:9 aspect ratio, however the resolution of the broadcast prohibited it from being considered a high definition channel, and in many cases not even SDTV. On June 27, 2007, CNN discontinued the CNN Pipeline service, to be succeeded by a free ad-supported live-video stream starting on July 2.〔(CNN Pipeline )〕 If the stand-alone Windows program was opened after June 27, CNN initiated an automatic uninstallation of the software from the subscriber's hard drive. CNN said that while it would continue to provide the four live video streams and video archives, it was abandoning the subscription model. According to CNN's blog, the reason they discontinued the service was to encourage a greater number of people to use the service. They stated they were not actually getting rid of Pipeline, or any of its features (other than the desktop program), rather funneling all of the content into CNN.com's video section for free.〔(CNN Blog )〕 This transfer of Pipeline from a pay service to an integrated free service came at a time of video being offered online for free ''en masse'', such as YouTube and TV networks offering full TV shows free online with ads, which did not exist at Pipeline's inception. In September of 2014, CNN announced CNNGo, an online service, effectively replacing Pipeline. The service contains many features from Pipeline, such as live shows and news clips. == "Pipes" == CNN Pipeline maintained four simultaneous feeds (known as "pipes"), which had both a primary and a secondary use. From 00:00 - 12:00 UTC on weekdays, and all day on weekends, the secondary use was shown on the feeds, meanwhile all other times the primary use was displayed. NOTE: The main news program was also on from 5:00 - 6:00 UTC on pipe 2 on weekends. Also on weekends, "The Best Of CNN Pipeline" was on at 9:30 AM EST and at 8PM EST is "Pipeline on Stage". The live raw feeds was of news events as they took place around the world, are were chosen by Pipeline's producers. Graphics of headlines, stock market indexes, and sports headlines took the place of advertisements during the main news program, and also when an advertisement appeared on CNN International when being simulcasted on the service. Contractual obligations prohibited the direct simulcasting of CNN's American news channels, "CNN" and "HLN" (unless the channel was being simulcast on CNN International). This prevented popular CNN personalities from anchoring live breaking news except when CNN International simulcasted the American service. Subscribers also received access to much of CNN's archive through the pipeline player. Additionally, regular featured programs found on CNN's American services were unavailable to Pipeline users. This fact was not made clear in advertisements for the service, so some American or Canadian users expecting online access to CNN and Headline News to which they were accustomed to were disappointed. Pipes was also used for special events as well. On September 11, 2006, the fifth anniversary of the September 11, 2001 attacks, CNN Pipeline carried a real-time rebroadcast of CNN's then-live coverage of the attacks for 15 and a half hours. Free access for Pipeline was offered for a day on November 6, 2006, in line with the US mid-term elections' coverage. 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「CNN Pipeline」の詳細全文を読む スポンサード リンク
