摘要
对播存电视终端相关技术进行了理论和实验研究。根据统一内容定位(Uniform Content Locator)技术,在实验室构建的有线电视广播网平台上设计了一种播存电视终端模型,实现了在应用层和数据链路层的UCL解析。同时设计了基于UCL的数据过滤机制,并进行了实验研究,完成了数据的解析、恢复和呈现。该模型有效地验证了基于UCL的数据过滤机制可行性。
The related technologys for the terminal of broad-storage TV is studied from the theory and experiment aspects. According to the UCL( Uniform Content Locator) technology, a kind of terminal model for broad-storage TV is designed on the platform of CATV broadcasting network structured in laboratory, which realizes the UCL analysis on the application layer and datalink layer. And the UCL-based data-filtering mechanism is designed,which is studied experimentally and completes the analysis, recovery and present of data. The model efficiently demonstrates the feasibility of the UCL-based data-filtering mechanism.
