ABSTRACT

In this paper, we propose a real-time video playback scheme for the N-Screen service based onWindows Azure. This scheme creates several playback blocks based on the performance of eachnode by non-uniform splitting of the original video. To reduce transcoding-time, it allocates the playback blocks to a corresponding node by transcoding the playback blocks. Through thesimulation, we show that it is more effective to use real-time video playback for the N-screenservice than the previous method. The proposed scheme splits an AVI format 300MB source videowith non-uniform playback blocks. It allocates the playback blocks to the heterogeneous node ofWindows Azure, the commercial cloud system and measures of transcoding-time by transcodingnon-uniform playback blocks to mp4 and Flv format. As a result, the proposed scheme improvesthe performance of the N-screen service based on Windows Azure compared to the previousuniform split strategy.
