An 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 two algorithms are compared by testing 12 compressed video streams according to the Motion-JPEG format. The new algorithms called e-PCRTT is shown to construct transmission rate-plans with smaller buffer sizes compared to the original PCRTT. Alternatively, for the same buffer size e-PCRTT reduces the number of bandwidth changes compared to PCRTT. In addition, e-PCRTT produces a rate- plane with smaller initial playback delay, which applications based on. We also introduce a new scheme for multiplexing several smoothed video traces, into a single constant-bit-rate channel that are synchronized nd have fixed-size intervals.
