Editing Video on demand (section)

==Functionality==
Downloading and streaming VOD systems provide the user with features of portable media players and DVD players. Some VOD systems store and stream programs from [[hard disk]] drives and use a [[RAM|memory]] buffer to allow the user to fast-forward and rewind videos. It is possible to put video [[server (computing)|server]]s on [[local area network]]s; these can provide rapid responses to users. Cable companies have rolled out their own versions of VOD services through apps, allowing television access wherever there is a device that is Internet capable. Cable media companies have combined VOD with live streaming services. The early-2020s launches of apps from cable companies (e.g., [[NBC]]'s [[Peacock (streaming service)|Peacock]], [[CBS]]'s [[Paramount+]]) are attempts to compete with Subscription Video on Demand (SVOD) services because they lack live news and sports content.<ref>{{Cite web|url=https://www.cordcuttersnews.com/the-roku-channel-is-the-most-popular-free-streaming-service-beating-out-pluto-tv-crackle-tubi-2018-cordie-awards/|title=The Roku Channel Is the Most Popular FREE Streaming Service Beating Out Pluto TV, Sony Crackle, & Tubi (2018 Cordie Awards)|last=Bouma|first=Luke|date=23 December 2018|website=Cord Cutters News|language=en-US|access-date=24 December 2018|archive-date=23 December 2018|archive-url=https://web.archive.org/web/20181223174932/https://www.cordcuttersnews.com/the-roku-channel-is-the-most-popular-free-streaming-service-beating-out-pluto-tv-crackle-tubi-2018-cordie-awards/|url-status=live}}</ref>{{Clarify|reason=|date=August 2019}} Streaming video servers can serve a wide community via a [[wide area network|WAN]], but responsiveness may be reduced. Download VOD services are practical in homes equipped with [[cable modem]]s or [[DSL]] connections. Servers for traditional cable and telco VOD services are usually placed at the cable head-end, serving a particular market, and cable hubs in larger markets. In the telco world, they are placed in either the central office or a newly created location called a Video Head-End Office (VHO).{{citation needed|date=October 2019}}
