A Server Coordinated Predictive Buffer Management Scheme to Reduce Bandwidth Requirement for Synthetic Multimedia Movies over the Internet.
Arvind Kumar Bansal, Rahul Pathak · International Conference on Internet Computing · 2003
Currently, for the display of synthetic and archived multimedia movies and clips, buffers are managed at the server end (push mode), at the client end (pull mode), or in the push-pull mode to avoid excessive server side disk access time, avoid hot spots for multiple disk accesses for the same media objects, and/or to smoothen the effect of variations in transmission delay. However, the current schemes suffer from the lack of static analysis and the coordination between server and the clients to reduce jitters. In this paper, we describe a server coordinated predictive buffer management scheme for mobile devices that integrates static analysis of frame based synthetic movies and server directed client side management to reduce the retransmission of reusable multimedia objects over the Internet. Performance evaluation shows that the scheme reduces the jitter significantly while maintaining the needed QoS, and the scheme outperforms popular rendering formats.
