中文摘要：

PC 的显示图象能被在 PC 的网络电报上使用进行的排放重建。被用来重建的相关信号原来的图象从切换红的放射正在联合，绿，在 PC 的蓝色(红绿蓝) 信号。这些恰当的信号部分在进行的排放比 30 MHz 高在频率区域被包含。从这些调查结果，到网络电报的从 PC 的近地的联合原则第一被分析。然后，为在网络电缆线播送的红绿蓝信号的一个多售票员传播模型被建议。另外，最大的安全距离被使用这个模型估计。以便检查估计的距离的有效性，偷听的实验被执行重建原来的显示图象。结果证明模糊显示器图象能在 29.5 m 的地方被检索。

英文摘要：

The display image of a PC can be reconstructed by using the conducted emission on the PC＇s network cable. The relevant signals which be used to reconstruct the original image are coupling from the radiation of the switching of red, green, blue （RGB） signals in PC. These pertinent signals are partly contained in the frequency region higher than 30 MHz in the conducted emission. From these findings, the near-field coupling principle from PC to the network cable is analyzed firstly. And then, a multi-conductor transmission model for the RGB signals which transmit in the network cable is proposed. In addition, the maximum safe distance is estimated by using this model. In order to check the validity of the estimating distance, the eavesdropping experiment is carried out to reconstruct the original display image. The results demonstrate that the blurred display image can be retrieved at the place of 29.5 m.
