Through the comparative analysis of irrigation management information systems based on relation database technologies and GIS technologies, we found that the latter has the merits such as integration of graphic data and attribution data, visualization of data and display of further characters using attribution data. The traditional relation-based database, which is good at storing and managing attribution data, is not able to describe and manage those data.

1通过对基于关系型数据库技术支持的灌区管理信息系统与基于GIS技术支持的灌区管理信息系统的比较与分析发现：基于GIS技术支持的灌区管理信息系统具有图形数据属性数据一体化、不仅可以用图形把数据直观地表现，还可以用属性数据表述其更加详尽的特征等优点，而传统的以存储、管理属性数据见长的关系型数据库用来描述和管理这些数据难免感到力不从心。

Information security usually adopt coding and information hiding technology ,though digital watermark belongs to information hiding technology ,its signification and application intention are different with information hiding .The hiding information is similar to the protected color of animal ,because the sneak can not ensure whether there is hiding information when he face a great deal of information to avoid of attack .Digital watermark is enchased into multimedia product to identify copyright data .

大多数时间域水印算法提供简捷有效的水印嵌入方案，且具有较大的信息嵌入量，但对语音信号处理的健壮性较低；变换域水印算法则具有较强的抵抗信号处理和恶意攻击的能力，但嵌入和提取过程相对复杂；压缩域水印算法是直接把水印信号加在压缩音频上的方法，它可以避免压缩算法编解码的复杂过程，但稳健性不高，而且能够嵌入的水印容量不大[2][14]。

This paper presented a multi-source uncertain data fusion model. This model analyzed and processed uncertain information from the aspects of rationality of information, reliability of sensors and comparability of information. The sensor information was filtrated by consistency of information and dependability of sensors, which dealt with conflicting information and false information.

The design of this dissertation begins with the definition of audience data structure based on considering the embedded developing environment features. The dissertation uses the STi5518 chip by ST Microtones to collect audience data, and then the SI analysis and OSD interactive function are used to gain the user watching information. Then collect audience data in EEPROM of STB, use STB and serial to transmit the data, then use the RS232 serial port and RJ-45 converter to realize the data Return of Serial to Ethernet, in the process of data Return it completes the conversion of data format.
