Abstract
A method and system for integrating occasional user-initiated data transfers with a generally continuous video transmission in a multimedia communications session includes enabling a party of the session to select at least two levels of video quality of service for the session. A first level is selected for time segments in which the user-initiated data transfers are active. A second level of video QoS is selected for time segments having user-initiated data transfers. Connectivity for the session is established based upon the first level. However, upon initiation of a data transfer, the video transmission requirements are switched to requirements based upon the second level of video quality of service. Present-time quality of service is monitored to determine whether the data transfer should be regulated so as to ensure that the present-time video quality of service remains at or above the second selected level. The method and system allow a user to determine what level, if any, of degradation is permissible during the data transfers.
