As the Internet access over broadband networks is growing, multimedia communications with video using MPEG will be widely used. User level QoS will be needed at ubiquitous and multimedia computing environment using MPEG, affects directly on human's sense. We conducted an experiment in order to investigate relation between MPEG encoding bit rates and user level QoS. The result shows that there is a threshold of user level QoS between 200 and 400 Kbps of our video streaming contents.
