A video conferencing system. In a type of conferencing known as "synchronized browsing," several computers download a common web page from a public-access, packet-switched network, such as the Internet. Software in a first computer informs the other computers how the first computer is navigating through the web page, and sends the other computers data which enables them to navigate the same path, so that all computers navigate in synchrony, and display the same sequence of images. Under the invention, while such a web page is being navigated by such computers, software observes one of them, and looks for the event of scrolling (as opposed to navigation). When scrolling is detected, its termination is awaited. When termination occurs, the invention tells the other computers which part of the page is currently being displayed, so that the others can navigate to that part and also display it.
