摘要
[目的 /意义]针对虚拟学习空间与数字图书馆多媒体服务融合的国内外现状及发展趋势进行分析,提出在数字图书馆新的服务背景下虚拟学习空间应具备的特点及核心功能。[方法 /过程]设计一种新型的基于移动终端的虚拟学习空间系统,即利用轻量级的多媒体存储格式及优化的XMPP网络协议传输来满足用户的交互性、系统体验的流畅性需求,并对新型虚拟学习空间的系统性能进行测试。[结果 /结论]从软件测试结果来看,系统运行稳定、传输效率高,保证了用户最佳的使用效果;从图书馆多媒体服务的传播效果来看,通过优化传输音视频文件可以提高受众的阅读效率,提升受众信息交互的感受效果,更好地提高图书馆多媒体信息的传播效果,利用多媒体技术建设的新型虚拟学习空间系统是新时代数字图书馆建设的突破。
[Purpose/significance] Based on virtual learning space and the digital library at home and abroad, this paper analyzes the present situation and development trends of multimedia services integration, and points out the required characteristics and core functions of virtual learning commons under the new circumstances of digital library. [ Method/ process ] It designs a new type of virtual learning commons system based on mobile terminal, which fulfills the needs of in- teractive and fluency through lightweight multimedia data storage and optimized XMPP internet protocol. [ Result/conclu- sion ] From the angle of software testing results, the stable running system and high efficiency transmission ensure the best usage effect. From the perspective of library, the communication effect of multimedia services by optimizing the transmit audio and video files improves the reading efficiency of audiences, improve the interaction quality of audience information, and plays a better effect on library multimedia information communication. Virtual learning commons relying on new media technology is a breakthrough for the construction of digital library in new era.
