    Patent number: 6990512
    Abstract: A method and system is disclosed for controlling real time presentation session through a communication network using control features embedded in a predetermined presentation software such as QuickTime Player. An original media server is first located for streaming a media file therefrom to present a real time presentation session. An Internet Cache System is situated between the original media server and the presentation tool having the presentation software.
