Modulation for scalable multimedia content delivery

Abstract

In this paper, we propose a new approach to perform real-time transcoding of images for pervasive Internet access. Taking full advantages of the trend of new image format and structure, this new transcoding mechanism, which we call it modulation, achieve the followings: (a) negligible overhead in real-time transcoding, (b) on-demand bandwidth consumption between the web server and the client/proxy, (c) maximum reuse of cached image variations, independent of whether it is from lower quality to higher quality or vice versa. Our result shows that this modulation approach gives full potentials for real-time image transcoding for pervasive Internet access. © Springer-Verlag Berlin Heidelberg 2005.
