'''Internet Protocol television''' ('''IPTV''') is the delivery of [[television]] content over [[Internet Protocol]] (IP) networks. This is in contrast to delivery through traditional [[Terrestrial television|terrestrial]], [[Satellite television|satellite]], and [[Cable television|cable]] television formats. Unlike [[download]]ed media, IPTV offers the ability to stream the source media continuously. As a result, a client media player can begin playing the content (such as a TV channel) almost immediately. This is known as [[streaming media]].
An IPTV service, typically distributed by a service provider, delivers live TV programs or on-demand video content via IP networks.
Although IPTV uses the Internet protocol it is not limited to [[streaming television|television streamed]] from the [[Internet]] ([[Internet television]]). IPTV is widely deployed in subscriber-based telecommunications networks with high-speed access channels into end-user premises via [[set-top box]]es or other [[customer-premises equipment]]. IPTV is also used for media delivery around corporate and private networks. IPTV in the telecommunications arena is notable for its ongoing standardisation process (e.g., [[ETSI|European Telecommunications Standards Institute]]).
