In this paper, a video transmission service using deterministic characterization and bandwidth renegotiation is proposed. In this service, we characterize a video stream at micro-segment and segment levels, and the bandwidth requirement will be determined as a tradeoff between the characterizations at these two levels, under the scaling of a parameter called degree of aggressiveness (DoA). The DoA parameter determines the degree of service robustness to be provided to the connection. Experimental results show that stream segmentation helps to increase the channel utilization, and higher DoA yields better quality of service because of increased level of service robustness.
