Over-the-top content (OTT)

OTT(Over the Top,網路服務)趨勢將帶來眼球革命

OTT服務是指「over-the-top」服務,通常是指內容或服務建構在基礎電信服務之上從而不需要網路運營商額外的支持。該概念早期特指音頻和視頻內容的分發,後來逐漸包含了各種基於網際網路的內容和服務。典型的例子有SkypeGoogle Voice微信等。網路運營商由於OTT業務的興起,日益被管道化
運營商管道化是指由於社交網路網路電話OTT服務的出現,電信公司僅需提供網路連接,而其原有的電話簡訊息等基礎服務受到威脅盈利減少的現象。[1]
Over-the-top content (OTT) refers to delivery of audio, video, and other media over the Internet without a multiple system operatorbeing involved in the control or distribution of the content. The provider may be aware of the contents of the Internet Protocol packets but is not responsible for, nor able to control, the viewing abilities, copyrights, and/or other redistribution of the content. This is in contrast to purchase or rental of video or audio content from an Internet service provider (ISP), such as pay television video on demand or an IPTV video service, like AT&T U-Verse. OTT in particular refers to content that arrives from a third party, such as DramaFever, CrackleHulumyTVNetDNetflixNowTVRPI TVWhereverTV, or WWE Network, and is delivered to an end user device, leaving the ISP responsible only for transporting IP packets.
An online video distributor (OVD) is defined as "any entity that offers video content by means of the Internet or other Internet Protocol (IP)-based transmission path provided by a person or entity other than the OVD."[1]
Over-the-top messaging refers to a similar idea, where a third party provides instant messaging services as an alternative to text messaging services provided by a mobile network operator.[2]
Consumers can access OTT content through internet-connected devices such as desktop and laptop computers, gaming consoles(such as the PlayStation 4WiiU, and Xbox One), set-top boxes (such as the Roku), smartphones (including Android phones, iPhones, and Windows phones), smart TVs (such as Google TV), and tablets. Consumers can access apps in most app stores.
