屏幕采集

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.

本设计首先在嵌入式环境的前提下，在用户数据采集和回传工作中采用了ST Microtones公司提供的STi5518芯片作为机顶盒主芯片，根据收视率调查需要制定出用户的收视信息数据结构，并结合数字电视业务信息分析以及机顶盒的屏幕显示互动功能，对用户的收视情况进行记录；然后把记录的数据存储到机顶盒的EEPROM中，并利用机顶盒串口输出数据，再利用RS232串口与RJ-45转换器实现串口转以太网的数据回传，在回传过程中完成了数据格式的转换。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
