农村信息化建设中多媒体数据的并行管理框架设计

Framework design of multimedia data parallel management in the informatization of rural areas

为了实现TD-SCDMA网络中多媒体数据的高效传输与分析,提出一种多媒体数据并行管理框架。该框架改进了多媒体数据管理中常规的顺序执行方式,实现了标准数据生成和原始数据分析的并行处理,减小了多媒体数据在传输和处理过程中的数据量且易于并行优化。以农村信息化建设中图像分析应用为切入点,探讨了该并行管理框架的具体实现方式。实验表明,采用该并行管理框架优化后,网络中图像数据传输量仅为之前的1/12,处理时间亦极大缩短,缓解了农村信息化建设中多媒体应用对TD-SCDMA网络传输带宽的需求。

In order to realize the efficient transmission and analysis of multimedia data under ll-）-b^uivi~ network, a parallel management framework is proposed. This framework improves the general framework for data management by parallelizing the generation of standardized data and the analysis of original data. It not only reduces the data volume in transmission and analysis, but also fits for parallel optimization. Focusing on image analysis in the informatization of rural areas, the authors introduce the procedures to realize the parallel management framework. As can be seen from experiment results, the data volume of image data is reduced to 1/12 after parallel optimization, and the time cost of analysis is substantially reduced. Thus, it can effectively relax the requirement of the TD-WCDMA transmission bandwidth for multimedia application in the informatization of rural areas.
