Abstract
This paper presents a linear-time method to optimize stored VBR video transmission on CBR channel. Given the transmission bandwidth, we have presented a linear-time method to minimize both the client buffer size and playback work-ahead. In this paper, the service connection time is minimized to maximize the network utilization for the given transmission bandwidth and client buffer. The required work- ahead is also minimized for the minimum response time. The proposed scheme can be extended easily to transmit the VBR video with minimum rate variability. Experiments of many well-known benchmark videos indicate that the proposed method can obtain better (or at least comparable) resource utilization and requires less memory buffer than conventional approaches. By considering the transmission of MPEG-1 video Advertisements with the same work-ahead time, our obtained results shows better network utilization than that of D-BIND. When compares by transmitting the long MPEG- 1 movie Star War, our approach uses smaller memory buffer than that of the combination of MVBA and D-BIND to achieve the same network utilization.
