PURPOSE: A method and an apparatus for encoding a multi-track video in a scalable video are provided to realize high speed by reducing a multi-track video in encoding time to a scalable video. CONSTITUTION: A video aligning unit(240) aligns two or more multi-track videos suitable for SVC(Scalable Video Coding) encoding. A bitstream analyzing unit(250) analyzes bitstream from first video of the lowest priority layer to a video of the highest layer and extracts encoding information. An SVC re-encoding unit(260) executes re-encoding based on encoding information. [Reference numerals] (210) Communication unit; (220) Original video storing unit; (230) Multi-track video encoder; (240) Video aligning unit; (250) Bit stream analyzing unit; (260) SVC re-encoding unit |
