Abstract

Smoothing is a transmission plan where variable rate video data is converted to a constant bit rate stream. Among them are CBA, MCBA, MVBA, e-PCRTT and others. E-PCRTT algorithm, which was improved from PCRTT, restricts the number of rate changes with fixed-size run. This causes unnecessary rate changes and may not guarantee QoS when buffer size is small. In this paper, a smoothing algorithm is proposed, where the number of rate changes are not limited and the size of run can be flexible, in order to overcome the shortcomings of e-PCRTT. Experiments demenstrated that the proposed algorithm outperformed other algorithms such as e-PCRTT. In order to show the performance, various evalution factors were used such as the number of rate changes, buffer size to maintain QoS, and so on.
