Cloud Gaming
Under Cloud Gaming (also Games on Demand ) is defined as an on playing computer games (german gaming ) aligned the Cloud. The game runs on external servers, and only the user input to the server and in return, even sound and video are sent to the client.
Function
Be made in cloud gaming needs no installation of the game, the audio and video files are first compressed and then transmitted directly via the Internet from the server to the client. There they are joined together with special video codec again. For server only need to commands from the mouse, keyboard, etc. are transmitted. Most of the load must be the server and the network handle. A major challenge is to carry very large data streams with less running time.
Delay
How big is the delay may be so as not to interfere with the game experience depends on the genre. At the Fraunhofer Heinrich Hertz Institute, the developers are aiming for delays under 0.1 seconds for cloud-based implementations in first-person shooters and other first-person games. In the third-person perspective of sports games for half a second is tolerable and strategy and other games omnipresent even one to two seconds.
