Abstract
A skimmed or preview version of multimedia content is provided to a client computer by a server computer using playlists. The skimmed version of multimedia content can be presented to a user of a client computer in less time than presenting the entire multimedia content would require. The server computer maintains skimming information that identifies particular segments of the multimedia content corresponding to the skimmed version. The server computer uses the skimming information to generate a playlist, which in turn is used by the server computer to access the appropriate segments of the multimedia content and provide the segments to the client computer.
