A n enhancement of the Piecewise Constant Rate Transmission and Transport (PCRTT) algorithm for reducing the burstiness of a video stream based on smoothing constant intervals is proposed. The new algorithm, called e-PCRTT, relies on geometrical considerations 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, and alternatively, for the same buffer size, e-PCRTT reduces the number of
