Abstract
A system and method for enabling real-time replay for videogames, wherein the player can selectively rewind the videogame to previously played points in the game in order to replay portions of the game during real-time. Inline keyframes are periodically recorded, together with the controller information, so that upon selecting the replay option, the game can be rewound to the nearest keyframe. Once rewound, the game is restored based on the keyframe and is then played back from the keyframe using the stored controller information. At any point during playback, the player can take-over the action and use the actual game controller to begin actual play of the game from that point in the playback sequence. The player can also change cameras and speed for the playback in real-time at any time during the playback.
