Abstract
A novel scheme of dynamic bandwidth allocation and buffer dimensioning based on the video playback tunnel and the jitter_index tunnel is proposed to guarantee the synchronization between the basic layer video stream and the enhancement layer video streams in the transmission of layered video streams over the Internet. The performance of the proposed scheme is evaluated using a set of real-life video traces with the focus on the effects of bandwidth, traffic burstiness and network traffic loading on the statistics of jitter_index between the basic layer and enhancement layers. The numerical results show that the proposed dynamic bandwidth allocation and buffer dimensioning scheme is able to significantly reduce the effect of interlayer jitters in the transmission of multiple layer-coded video streams over the Internet.
