Abstract
A method and apparatus for synchronizing viewed information between a first endpoint and a second endpoint of a conferencing environment so that the first and second endpoints display the same location of the viewed information includes one of the endpoints receiving a request to synchronize the viewed information. An identifier of the location to which the document is to be synchronized is also received. The viewed information at the endpoint is then updated to display the identified location. In one embodiment, the first endpoint receives the request to synchronize the viewed information and sends a view synchronization message to the second endpoint. The view synchronization message includes a page identifier corresponding to the identified location and a center point which identifies a location within the page corresponding to the page identifier. Upon receipt of the view synchronization message, the viewed information at the second endpoint is updated to display the identified location.
