字幕表 動画を再生する 英語字幕をプリント Over-the-top content refers to delivery of audio, video, and other media over the Internet without a multiple system operator being 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, 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 Dramatize, DramaFever, Crackle, Hulu, myTV, NetD, Netflix, NowTV, RPI TV, WhereverTV, or WWE Network, and is delivered to an end user device, leaving the ISP responsible only for transporting IP packets. An online video distributor is defined as "any entity that offers video content by means of the Internet or other Internet Protocol-based transmission path provided by a person or entity other than the OVD." 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. Consumers can access OTT content through internet-connected devices such as desktop and laptop computers, gaming consoles, set-top boxes, smartphones, smart TVs, and tablets. Consumers can access apps in most app stores.
