摘　　要：课件媒体展现能力是可共享内容对象参考模型SCORM(Shareable Content Object Reference Model)的关键技术。针对多媒体课件播放的兼容性和流畅性等问题,在对SCORM的运行时间环境概念模型(RTE)进行扩展的基础上,结合SCORM标准和P2P等相关技术,提出基于SCORM技术的多媒体课件统一播放框架(MC_UPF)。基于此框架研发MC_UPF课件播放器,由RTE内核解析播放课件,从而解决诸多用户体验问题。这不仅保证了学习资源的一致性和完整性,还解决了用户浏览器兼容问题带来的困惑及相关插件安装方面的不便。通过详细介绍MC_UPF课件播放器的实现流程,验证了该框架的可行性。The presentation ability of courseware media is the key technology of SCORM.Aiming at the problem of compatibility and smoothness of multimedia courseware,we proposed a unified play framework of multimedia courseware based on SCORM(MC_UPF).It extended the conceptual model of run-time environment(RTE)defined by SCORM and combined SCORM standard,P2P and other related technologies.Based on this framework,we developed MC_UPF courseware player,which was parsed and played by RTE kernel,so as to solve many user experience problems.It not only guarantees the consistency and integrity of learning resources,but also solves the confusion caused by the compatibility of user browsers and the inconvenience of installing related plug-ins.The implementation process of MC_UPF courseware player is introduced in detail,and the feasibility of the proposed framework is verified.
