METHOD FOR TRANSCODING MULTIMEDIA, AND HADOOP-BASED MULTIMEDIA TRANSCODING SYSTEM FOR PERFORMING THE METHOD

摘要

A multimedia transcoding method and a system for performing the multimedia transcoding are provided. A hadoop-based multimedia transcoding system may include a video and image data collection domain (VIDCD) to collect original encoded media data sets, and to store the collected original encoded media data sets, a hadoop distributed file system (HDFS)-based splitting and merging domain (HbSMD) to split the original encoded media data sets into first blocks, and to automatically distribute the first blocks to a plurality of data nodes of an HDFS, by using the HDFS, and a MapReduce-based transcoding domain (MbTD) to transcode second blocks distributed to the plurality of data nodes, through distributed and parallel processing, using a MapReduce framework.
