Abstract
This paper presents new multimedia transmission and synchronization scheme for parallel server in wireless environment. The proposed scheme is developed for the parallel sewer that stores MPEG-4 data according to VOP (video object plane) types, i.e., I-, p-, and B-VOP. The goal of our research is to develop the enhanced multimedia transmission scheme that copes with load unbalancing, congestion, and jitter. Thus, we consider three issues; the data striping, the priority queuing, and the multimedia synchronization. First, we develop a parallel server architecture in which each server separately stores video data that is striped by the MPEG-4 VOP types.
Keywords
Multimedia stream; data striping; priority queue; synchronization; MPEG-4;
