Abstract: A multimedia server system and a method for communicating multimedia programming to distantly situated media control systems are disclosed. The multimedia server system includes a mass storage library for storing a plurality of multimedia programs. A multimedia program is coded in accordance with a predetermined compression standard and stored in a compressed digital format as sequentially ordered discrete program segments in the mass storage library, with each of program segments being representative of a unique portion of the multimedia program. A video parser organizes the sequentially ordered program segments of a multimedia program into a custom ordered series of program segments preferably including non-sequentially and sequentially ordered program segments in accordance with configuration parameters associated with the configuration and presentation control features of a media control system requesting the multimedia program.
