Abstract: The present invention relates to a technology for effectively detecting a moving object from a compressed video based on H.264 AVC, H.265 HEVC, etc. in general. More specifically, the present invention relates to a technology for extracting any meaningful movement existing region, namely, a region of a moving object, within a video by using syntax information (e.g., motion vector, coding type) acquired by parsing compressed video data, not recognizing object presence through complex image processing like a prior technology with respect to, for example, a compressed video generated by a CCTV camera. Particularly, in the case that an object motionlessly stops or performs any behavior at the same position temporarily after the region of the moving object is extracted, the present invention maintains the region of the moving object without erasing the region by considering context of the video even if there has been no motion vector in the meantime, thereby removing error possibility in an approach method for detecting the region of the moving object by syntax without analyzing content of the video and accordingly, enhancing reliability and usability in extracting the region of the moving object.
