Abstract
A new system and method for sharing graphical display information in a collaborative tool is disclosed which samples graphics display information regarding a shared display region on a server system. The disclosed system updates client systems regarding changes in the shared display region responsive to detection of a change in the shared display region contents. The disclosed system further modifies a polling rate used to sample the graphical display information on the server responsive to the frequency of changes to the shared display region. Specifically, in an example embodiment the disclosed system shares a display region among a plurality of users by selecting a first bit map from a series of bit maps used to display the shared display region on a server system. The server system then transmits said first bit map to a client system. The server system periodically selects a subsequent bit map from the series of bit maps at a polling rate. The server system later determines whether said shared display region on the server system has changed. If the shared display region has changed, then the server system transmits a representation of the subsequent bit map to said client system. The server system increases the polling rate responsive to determining that the shared display region on the server system has changed.
