An enhancement of the Piecewise Constant Rate Transmission and Transport (PCRTT) algorithm for reducing the burstiness of a video stream, based on smoothing constant interval is proposed. The new algorithm, called e-PCRTT, relies on geometrical consideration rather than traditional rate-control analysis. E-PCRTT is shown to construct transmission rate-plans with smaller buffer sizes, as compared to the original PCRTT. Alternatively, for the same buffer size, e-PCRTT reduces the number of bandwidth changes as compared to PCRTT. In addition, e-PCRTT produces a rate-plan that requires a smaller initial playback delay.
