Generation and caching of content in anticipation of presenting content in web conferences

摘要

A method, system and computer program product for sharing the contents of a presentation in a web conference. A web conference server in a web conferencing system extracts a document that is likely to be viewed by the presenter during the web conference prior to the presenter actually viewing the document. The web conference server processes the extracted document into a displayable screen image which is sent to the participant computers in the web conference to be cached. When the presenter computer actually displays the extracted document, the web conference server informs the participant computers to display the cached screen image. Since the screen image of the document has already been cached by the participant computers, the document will be more quickly viewed by the participant computers and will reduce the time lag between when the presenter views the document and when the audience views the same content.
