On Utilization of the Cluster Computing Technology for Video Conversion

Abstract

The popularization of broadband network and the development of MPEG-4 compression technology urge to the multiplexing development of Internet information. Among these techniques, Video-on- Demand is the most popular service. However, it takes extremely long compression time to convert audio and video data into MPEG-4 format. Although MPEG-4 enhances the compression ratio, it still needs massive storage equipment to deposit the audio and video data. The price of MPEG-4 related hardware equipment still stays at a high level currently. Thus, these problems can easily be solved by using the cluster computing technology, or PC Clusters. In this paper, we use the Linux PC cluster to achieve the high performance video conversion. Moreover, we use diskless cluster computing technology to make it more convenient in the system administration. In video conversion aspect, we use software tool called “dvd::rip” to perform in parallel the video compression, with the goal to achieve the best execution time, by enabling that each node to perform in its best processing potency.
