Transcoding has a significant effect on streaming media services in wire-less networks. The goal of this paper is to reduce network traffic due to high network bandwidth demand and streaming constraints, and enhance the performance of streaming media services. Therefore, the authors propose a new OVT (Object Version Transcoding) mechanism based on fuzzy similarity. This work derives a media object relationship to calculate the individual fuzzy similarity of certain versions of a media object. They take into account transcoding constraints such as media object characteristics, cache capacity and the properties of the object versions. Based on the given constraints, the proposed mechanism reduces the startup delay and congestion, and it increases the response rate and cache hit rate.
