The design of the modern electronic device, except for must has multiple functions, but it also trend to achieve slightness, thinness, shortness and smallness in outer appearance. In order to seek such a trend, the components disposed in the electronic device must be reduced in volume correspondingly, and the connectors used therein also must be reduced in volume without exception. For example, the USB connector has developed a mini USB connector, and the digital video signal transmission interface evolves from a digital video interface to a high definition multi-media interface having a smaller volume and a faster transmission speed.

现代电子产品的设计除了要功能多样外，在外观上的趋势是追求轻、薄、短、小，为了追求这样的趋势，电子产品内的各个零件也必须跟着将体积缩小，其所使用的电连接器当然也不例外，如通用串行连接埠推出迷你版的通用串行连接端口，而数字影音讯号的传输接口也由数字视觉接口推演到体积较小，传输速度更快的高速高解析多媒体接口。

By analyzing the results of LSNR measurements for samples with different components, and comparing with the media of Aprilis Corporation, we give the suggestion to optimize the material components in the future. In addition, based on the physical mechanism of intra-page crosstalk noise, we proposed the Pixel-Matched Spread Function, and a simplified deconvolution arithmetic to suppress the intra-page crosstalk noise.

另外，在分析数字数据全息存储中页内串扰噪声产生的物理过程的基础上，提出了像元匹配扩散函数的概念，并提出了一个反卷积算法来抑制页内串扰噪声，计算机模拟和实验结果都证明我们提出的PMSF算法可以有效的抑制页内串扰噪声，提高恢复数据页的保真度。

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.
