| 摘要: |
| 分布式多媒体是分布式计算技术和多媒体技术相结合的新兴技术，其基本特征是实现异地多媒体信息共享．由于连续媒体数据与传统数据在特性上的巨大差异，使得传统网络服务器和相关的存储系统不再适宜支持异地连续媒体的服务，所以要求代之以新的存储系统．本文介绍了作者所开发的分布式多媒体并行服务系统．该系统通过引入系统资源秩概念，实现了多访问流的并行操作，从而弥补了现有服务系统在设计上的主要缺陷．另外，文中给出了一组视频访问流的测试数据，其结果显示出系统对多媒体应用的良好支持. |

| Abstract: |
| Distributed multimedia, whose aim iS to support non- local accesses tO multi．media information，is a new research domain．Because of the significant differences the characteristics of continuous media data from ones of conventional data, conventional file servers and associated storage systems are not well suitable for non-local multimedia appli．cations；instead，new service systems capable of doing SO．In the paper，authors introduce a new distributed multimedia parallel service system designed and built．By the concept “system resource order”．the mutual parallel operations of multi-access stream are real-ized．So，the main defects in the design of existing systems are well solved．Additionally，a group of video access streams is simulated in the paper，and the conclusion is that the system iS well suitable for continuous media applications． |
