摘要

UCL(Uniform Content Locator)是作者、编者和读者进行语义沟通的工具

是数据广播中解决接收端数据信息的快速选择、信息过滤、智能代理和信息的主动服务的基础.本文系统地介绍了数据广播中UCL的概念

提出了在数据广播中进行UCL标引的方法和两级复用方法

研究了数据广播的UCL-W标引方案

研究了多映射与复用技术

最后给出了在数据广播的传输过程中

发送端对数据信息进行采集、标引、映射、复用、格式转换和调制的工作流程.实验验证了理论方案的正确性和有效性.

Abstract

UCL(Uniform Content Locator)build a bridge between writer and reader for better understanding

which is a key technique for data processing such as receiving quickly

information filting

service intelligently and actively in data broadcasting.The methods of UCL-W indexing and multiplexing are put forward for Web service in data broadcasting

and the techniques of multimapping and bistage multiplex are studies in this paper.And then the flow diagram of the data processing

including data gather

UCL indexing

multimapping

multiplexing

data format transform

modulation

are figuir out.The experiment result shows that the creative methods and the new designs are correctly and efficiency based on DVB-C network.
