摘要
为了适应PDR网络化、个人化的发展要求,本文提出了PDR节目数据库管理软件中一些关键模块的设计方案。这些方案包括实现节目列表的新型集合、符合MPEG-7标准的节目预告描述方案、统一的节目资源管理方案及其在提供电子节目单和完成预约录制方面的应用。实验证明以上各方案的性能均优于目前PDR产品所采用的相应方案。
In this paper, design schemes on several crucial parts of the PDR (Personal Digital Recorder) database management software are presented for meeting the requirements of developing it into a popular networked and personalized product. They include a new collection that can implement program list, a description scheme of TV program forecasting that complies with MPEG-7 standard and a unified program resource management scheme along with its applications to EPG generating and scheduled recording. Experimental results show that their performances are better than that of the corresponding schemes currently used for PDR products.
