Abstract

본 발명은 감시용 카메라 시스템에서 영상데이터의 파일생성 방법 및 그에 따른 기록 및 재생 방법에 관한 것으로서, 영상데이타의 파일을 생성하는 방법은 여러개의 영상 프레임을 연속적으로 형성하는 영상파일과, 상기 영상 파일에 대응되는 영상파일이 생성된 시간, 입력된 비디오 채널, 경보의 유무 및 영상파일을 구성하는 프레임의 위치 등의 정보를 갖는 헤더파일을 포함한다.A method of generating a file of video data in a surveillance camera system, and a method of recording and playing back the video data in a surveillance camera system, the method comprising the steps of: generating an image file that continuously forms a plurality of video frames; And a header file having information such as the time at which the video file corresponding to the video file is generated, the input video channel, the presence of the alarm, and the position of the frame constituting the video file.

따라서, 상술한 바와 같이 본 발명에 따른 감시용 카메라 시스템에서 영상데이터의 파일생성 방법 및 그에 따른 기록 및 재생 방법은 여러 개의 프레임 단위로 영상파일을 생성하고, 생성된 파일에 대한 정보를 형성하도록 기록함으로써, 원하는 영상데이터를 빠른 시간 내에 검색하여 검색 시간의 고속화 및 기록 용량의 최소화를 실현할 수 있는 효과를 갖는다.Therefore, as described above, in the surveillance camera system according to the present invention, a method of generating a file of image data and a recording and reproducing method according to the present invention generate image files in units of frames and record Thus, it is possible to search desired video data in a short period of time, thereby realizing a high-speed search time and minimizing a recording capacity.
