Paper Abstract

The use of multimedia data is growing at a rapid rate, and bringing multimedia services to terminals with limited capabilities is a major challenge. Efficient schemes are hence required for adapating the multimedia content for delivery to devices with limited resources. In the conventional server and proxy-based architectures, the adaptation is performed either at the server or at the proxy resulting in the loading of the server and the proxy. In this paper we propose a novel distributed adaptation architecture suitable for resource-limited multimedia terminals as well as wired connections with high bandwidths. Here, the data can be adapted at the proxy or at the server, resulting in a faster adaptation process. In addition, we propose an efficient cache replacement policy at the proxy. The proposed architecture is very flexible for both mobile and wired networks. The experimental results show that the proposed architecture improves the performance of the proxy and the server, and reduces network congestion and latency.
