在分析关联信息模型、分离信息模型基础上,提出了数字内容包装的综合信息模型,并基于此模型设计了打包内容容器的文件头数据结构和文件模型,从而为数字内容包装和分发创造了条件。在分析数字内容的超级分发模式基础上,同时考虑到数字内容分发过程中内容使用者地位的缺失,设计了内容使用者为中心的用户定制内容分发模式。之后,在数字内容密钥分解的基础上,详细地说明了数字内容包装的关键过程,并进一步实现了内容包装工具和内容分发系统。

Based on the analysis of the associated and separated model, a comprehensive digital content packaging information model is proposed, and then, based on this model the data structure of the packaged content container header and its model as well, which created the conditions for digital content packaging and distribution. Based on the analysis of the superdistribution model of digital content, and taking the lack of user position during the distribution of digital content into account, a user-cen- tered and user-customized content distribution model is designed. Then, based on the decompositio...
