Abstract

Compressed multimedia transmission is assuming a growing importance in the telecommunication world. However, the high data rate variability of compressed video over multiple time scales makes an efficient bandwidth resource utilization difficult to obtain. Smoothing techniques is one of the approaches exploited to face this problem. Various smoothing algorithms have been proposed, that reduce the peak rate and high rate variability of video streams by efficiently prefetching video data to be transmitted over the network. However, all previous algorithms consider a constant available bandwidth. Such a constraint can be hardly verified in modern telecommunication networks. In this paper a novel online smoothing algorithm is proposed, that performs data scheduling by taking into account the residual available bandwidth, and at the same time minimizing rate variability changes. This algorithm can be fully exploited for online smoothing of video applications that want to tolerate very short playback delays. Numerical results show that the proposed algorithm is very effective for online smoothing purposes in a link sharing environment.
