Abstract

This paper describes a distributed video transcoding system that can transcode an MPEG-2 video file into various video coding formats with different rates, and its application to grid delivery of video. The transcoder divides the MPEG-2 file into small segments along the time axis and transcodes them in parallel at transcoding nodes. To cope with heterogeneity and time-varying performance of transcoding processors in grid computing environment, dynamic scheduling algorithm is proposed. The simulation results demonstrate that the proposed dynamic scheduling algorithm can decrease total transcoding time by 30% in uniform performance fluctuation environment, compared with static scheduling.
