Method and apparatus for sharing a live presentation file over a network

A method and a device for sharing a presentation file in real-time are provided to enhance a learning effect by enabling a viewer to play the presentation file later in the same sequence and voice as a seminar environment, as presenter information such as text and the voice of each slide is extracted/stored to a viewer terminal without any equipment like a camcorder. An information extracting/storing module(12) temporarily stores text and graphics of a presenter from each displayed presentation screen by corresponding to a display position, and records voice of the presenter. An information transferring module(14) transfers information received from the information extracting/storing module to the outside. A user permission module(16) permits access to the information transferring module from the outside. A storage unit(18) stores the information received from the information extracting/storing module. A viewer terminal(20) includes a user request module(24) requesting the presentation screen and a presentation information file to a presenter terminal(10), an information receiving/storing module(22), an information playing module(26), and the storage unit(28).
