Abstract: A method and system that remotely modifies presentation data in a multimedia conference. The conference moderator can remotely issue commands that change the HTML and Javascript or create new HTML or Javascript for the web page being presented to the conference participant. The moderator is changing the HTML and Javascript displayed in the conference participant's browser window, by remote control. The HTML and Javascript in the participant's presentation data is changed so that the participant views what the moderator directs. This is not predetermined, but can be changed by the moderator at any time. Through the use of a presentation Java applet, the moderator of a conference is able to place annotation commands into the empty annotation containers of a conference participant's annotation shell page. The moderator chooses annotation commands for the containers and then transmits the commands to a viewing Java applet at the participant's DPS.
