| Abstract: | A general video storage and retrieval scheme of embedded digital video surveillance system is developed to improve the poor reusability and I/O bottle-neck of video storage and retrieval whose architecture are different each other in most existing video surveillance system. The video storage and video retrieval are implemented with embedded component-ware. This scheme reduced I/O bottle-neck by designing storage dispatch algorithm and retrieval congestion by adopting retrieval control policy. Compared with the video storage and retrieval methods of early video surveillance systems, it shows improved performance in supporting multi-channels of video storage and retrieval and better reusability. |
