摘要
在非线性编辑系统中，视频的实时存取策略需满足两点要求：一是尽可能充分利用硬盘的存储速率．在存取视频时，尽量减少移动硬盘磁头的时间．二是尽可能充分利用硬盘中的碎片．常用的随机存储与连续存储策略均不能满足上述的要求．本文提出了分块存储策略．实验证明，该策略在提高存取速率的同时，能有效地减少硬盘中的碎片．
In a nonlinear editing system, real time storage of video requires: Firstly, utilizing the storage speed as possible as we can. Secondly, Using out the fragment in a disk. The common random access and sequence access can't satisfy the above requirements. We present the policy of block access in this paper. It can greatly decrease the fragment with improving the speed of access.
