Abstract

As of today, video games have the capability to save the play context in a storage media typically in a non-volatile memory media so that player can save the current state of the game and restore it at later time after the game console is powered off. This is better than restarting the game all over again each time. However, there is inevitable discontinuity in play experience. Recent gaining popularity of portable game players such as the introduction of PSP (PlayStation Portable) and its network capability (PS3 will be also equipped with network), this discontinuity can be overcome by synchronizing the game context between a console and a portable player. For example, when a game is first being played on a console. A portable game console is later turned on and put into a synchronization mode. At first the current context of the game is transferred from the console to the portable player. Once both systems share the same set of physical parameters, two can exchange the update to each other to keep them in sync. Now the identical game play can be played either on the console or from the portable player simultaneously. If the console is turned off, then the game context continues to live on the portable platform. The user can continue to play the same game while he or she transports to a different location. If the console is available at the destination, the reverse process can transfer the live context again back to a console in real-time. The game must be developed for each platform (i.e. PS2, PSP, PS3) and be designed to sync and migrate the context in real-time via network.
