Optimization of Storage Method for Video Segment Captured by Embedded System in Camera

摘要

Video processing and cache capacity in embedded system in camera is the key to decide intelligence of shooting system. In particular, to meet the demand for continuous monitoring in video surveillance environment, the embedded system must be able to store the video in case of failure in network or server. In this paper, a storage method for videos with fixed size is proposed, which can effectively restrain occurrence of fragment during storage and raise I/O performance while ensuring continuity of monitoring. Furthermore, storage of video data based on H.264/AVC encoding system and its optimization are also discussed.
