研究了文化信息共享平台中的统一内容定位技术,提出了标引信息的传输映射实现方案。根据标引信息的信道映射、文件头映射和TS流映射3种不同的映射方法,在DVB-C实验平台下,分别实现文化资源的定制、智能代理和快速下载等功能,并给出了文化信息共享平台应用前景。
The Uniform Content Loeator (UCL) in the platform of cultural information sharing is investigated,and the transmission mapping schemes are presented. Based on the three kinds of mapping method of UCL indexing information ,such functions as the booking of cultural resource,intelligent agent and fast download are implemented on the experimental platform of DVB-C.
