Abstract[目的]提出机构知识库影音支持能力扩展方向,实现CSpace机构知识库影音支持能力扩展。
[应用背景]影音知识资源在机构产出中所占比例不断增长,扩展机构知识库影音支持能力,可更好地的揭示、发现影音知识资源,挖掘和利用其学术研究价值和潜力。
[方法]分析用户的应用需求和国内外机构知识库影音支持服务的发展趋势,构建机构知识库影音资源支持功能扩展框架,选择其中的关键技术和方法搭建实验平台,探索将其应用于CSpace系统的可行性。
[结果]实现了影音格式转换、视频场景分析和具有场景导航功能的播放器。
[结论]影音转码稳定性和效率较好,其他影音支持功能离实用还存在一定距离,将影音格式转换技术应用于CSpace机构知识库系统中,扩展了机构知识库的影音支持服务。
Other Abstract[Objective] The paper aims to propose the extension direction of Institutional Repository's supporting ability for audios and videos and realize its functional extension in CSpace.
[Context] Audio and video resources in the proportion of institutional output continues to grow, expanding Institutional Repository's supporting ability for audios and videos, will be better reveal, find audio and video knowledge resources, mining and use of its academic research value and potential.
[Methods] The paper analyzes the application requirements of users and the development trend of Institutional Repository's supporting services for audios and videos both at home and abroad, constructs its functional extension framework, selects the key technologies and methods to build the experimental platform, explores its application feasibility in CSpace.
[Results] Realized the video format conversion, video scene analysis and video player which has the function of scene navigation.
[Conclusions] The transcoding technology for audios and videos is more mature, but other supporting functions are still a certain distance from the practical application. This paper applies the format conversion technology for audios and videos in CSpace and finally expand its supporting services.
