摘要
分析了HDTV视频存储的原理,讨论了实际应用中通用文件系统在连续媒体存储方面遇到的问题,归纳出多媒体文件系统应具备的功能和磁盘调度算法,提出了一种满足连续媒体存储策略的专用文件系统,提高了资源利用率和服务质量,并基于系统硬件平台,设计了适用于软件实现的算法逻辑。
This paper analyses the principle of HDTV video storage, and discusses some problems in practical use of general file system dealing with continuous media. The paper also concludes the functions and disk dispatch algorithm of the muhimcdia file system. As a result, a special-purpose file system is proposed to meet the storage strategy of continuous media, improving the rcsource utilization and the quality of service. An algorithm suitable for software development based on the system hardware platform is proposed.
