Many studies have been performed for streaming of multimedia data in response to the recent increase in requests for wireless services and multimedia services based on distributed networks. The typical schemes for distributed multi-media service are CMD (Centralized Multimedia Distribution), client-server architecture, CDN (Content Distribution Network) and P2P- (Peer-To-Peer) based scheme. In this paper, the authors propose a new proxy caching scheme with fuzzy filtering based on partition and mapping of media block segments. In the scheme, media block segments are divided into fixed and variable partition reference blocks, and the mapping is performed by semantic relationship. The proposed scheme helps to alleviate the problems of the typical schemes.
