【摘要】 目的解决传统媒体流应用不足的问题。方法以构件技术为核心,在CORBA环境下,引入多种构件交互方式和软件复用机制,组装和定制媒体流应用。同时,通过给出一个媒体流应用系统的具体实例,重点讨论了CORBA环境下媒体流应用领域中交互风格的设计与实现问题。结果提出一个基于CORBA的分布式媒体流构件模型CCMM。结论CCMM实现了异构平台开放接口,有利于不同平台的媒体服务和客户进行交互;构件技术屏蔽了开发细节,降低了开发难度。CCMM使媒体流系统成为了一个可以方便组合的构架,可以方便地实现系统的维护、升级以及构件的替换、定制,提高了开发效率。更多还原

【Abstract】 Aim A study on media traditional stream application by using component technique in CORBA environment . Methods In CORBA environment, based on component technique, interaction styles and reuse of software are introduced to custom stream application. At the same time , a real case of media steaming application is studied. And the interaction styles of designing and implementing in CORBA environment media application are discussed in detail. Results Distributed component and CORBA based media stream application model, called CCMM, are proposed. Conclusion Based on the model, the difficulty of media application development is reduced and the research work has important practical value.更多还原
