数据广播中内容定位技术的软件实现

Software realization of content location technology in data broadcasting

介绍了数据广播中统一内容定位(UCL)规范的原理和系统结构,采用树形结构组织节目信息,并采用独立信道数据管道模式传送。给出了一种内容定位的软件实现方案,分析了设计要点。实验结果表明UCL技术的可行性和有效性。

This paper presents the principle and structure of the Uniform Content Locator(UCL)in Data Broadcasting.The program information is organized in the Tree-structure,and is transmitted by Data piping of DVB in a special channel.The implementation of UCL based on software is described in detail,and the key of the software design is analyzed.The results of experiment indicate that UCL is feasible and effective.
