Cloud gaming

Cloud gaming runs a video game on a remote server and streams its audio and video to a player's device, which sends control inputs back over a network.

Game streaming: Delivery of interactive gameplay video from a server to a client device over a network. Cloud gaming is a form of game streaming in which the server runs the game itself.
Video game: An electronic game in which players interact with audiovisual content through a computing device. Cloud gaming changes where a video game runs, not what makes it a game.
Smart TV: A television with network connectivity and software for running internet-based services. A smart TV can display streamed games without running them locally.
Local gaming: Playing a game whose main computation runs on the player's own device. Unlike cloud gaming, local gaming renders frames on the device rather than a remote server.
Video encoding: The conversion of video into a compressed format for storage or transmission. Remote gameplay must be encoded quickly enough to stream each rendered frame.
Cloud computing: On-demand access to computing resources delivered over a network. Remote servers supply the processing resources that execute streamed games.
Smartphone: A mobile phone with an operating system capable of running applications and accessing networks. Cloud gaming can bring demanding games to phones that lack equivalent local hardware.
Game download: The transfer of game software to a device for local installation and execution. A downloaded game can run locally, whereas cloud gaming streams the running game.
Video decoding: The reconstruction of video frames from a compressed bitstream. The client decodes streamed frames before displaying them as gameplay.
Client–server model: A computing architecture in which client devices request services from servers. The player's device acts as a client while a server runs the game.
