US Patent 9381432 Game migration

Embodiments of the present invention allow game play to migrate back and forth between a server-run video game and a client-run video game. For example, a user could start playing a video game running on a server and then migrate play to a client device, such as a game console. When a game is running on the server, the server executes the game code, renders a video image, and communicates the image to the client. The client may communicate game control commands to the server. The game play may also start on the client and transition to a server. For example, a user may reach a point in the game where the user does not have the game files stored on the client.
