    • It is arranged so that the history of access to a web page at a terminal device that does not have a unique IP address can be determined. To achieve this, a proxy server generates identification data of the terminal device upon accepting a request for a web page from the terminal device the first time. A link destination URL included in the web page conforming to the request is changed by the proxy server and a web page in which the URL after the change has been embedded is displayed on the terminal device. If the proxy server is requested for the web page having the URL after the change, the URL is restored by the proxy server to the URL that prevailed before the change and the web server is requested for the web page having the URL that prevailed before the change. Since the URL after the change is one that only the terminal device of the generated identification data can ascertain, the history of access by the terminal device can be determined by storing the URL, which prevailed before the change, of the requested web page in correspondence with the identification data.
    • 可以确定在不具有唯一IP地址的终端设备处访问网页的历史。 为了实现这一点,代理服务器在第一次从终端设备接受对网页的请求时,生成终端设备的标识数据。 包含在符合请求的网页中的链接目的地URL被代理服务器改变,并且在终端设备上显示其中嵌入了改变之后的URL的网页。 如果在更改后请求具有URL的代理服务器,则该代理服务器将该URL还原到更改之前所占用的URL,并且请求具有在 更改。 由于变更后的URL是仅生成的识别数据的终端装置能够确定的URL,所以终端装置的访问历史可以通过将所请求的网页的通信存储在变更之前的URL来确定 具有识别数据。

    • It is arranged so that the history of access to a web page that has been returned to can be determined even in a case where a “BACK” button on a browser has been clicked. Owing to a transition from one web page to another in response to clicking of hot text from the one page to the other, the URL of the destination web page is transmitted to a server. As a result, the URL of the source web page and the URL of the access destination can be recognized by the server. In a case where one web page is returned to from another web page by pressing the “BACK” button on a browser, a URL is not transmitted to the server. Therefore, a URL combination in which the source URL and the access destination URL have been interchanged is generated and stored in an access history table. Thus, even if the preceding web page is restored by pressing the “BACK” button, the server is capable of ascertaining history of the access.
    • 即使在浏览器上的“BACK”按钮被点击的情况下,也可以确定已经返回的网页的访问历史。 由于响应于从一页到另一页的热文本的点击,从一个网页到另一个网页的转换,目的网页的URL被发送到服务器。 因此,服务器可以识别源网页的URL和访问目的地的URL。 在通过按浏览器上的“BACK”按钮从另一个网页返回一个网页的情况下,URL不会发送到服务器。 因此,生成源URL和访问目的地URL已被互换的URL组合并将其存储在访问历史表中。 因此,即使通过按下“BACK”按钮恢复前一网页,服务器也能够确定访问历史。

    • Moving-image data is streamed to a large number of client computers even though line band of a streaming server is kept narrow. To achieve this, the address of a relay server closer to a client computer than is the streaming server is transmitted when the client computer issues the streaming server a connection request for moving-image data. The client computer then sends this relay server a request to transmit the moving-image data. When this occurs, the address of another relay server even closer to the client computer than is the first-mentioned relay server is transmitted to the client computer. Since this other relay server is closest to the client computer, moving-image data is streamed from this relay server to the client computer.
    • 移动图像数据流传输到大量客户端计算机,即使流媒体服务器的线路段保持较窄。 为了实现这一点,当客户端计算机向流服务器发送运动图像数据的连接请求时,传送比流服务器更靠近客户端计算机的中继服务器的地址。 然后,客户端计算机向该中继服务器发送发送运动图像数据的请求。 当发生这种情况时,与首先提到的中继服务器相比,更接近客户端计算机的另一中继服务器的地址被传送到客户端计算机。 由于这个其他中继服务器最接近客户端计算机,因此将运动图像数据从该中继服务器传输到客户端计算机。

    • In a case where a padded orthogonally transformed block obtained by orthogonally transforming a padded image block of 8×8 pixels to which padding data has been added has been recorded as compressed image data, the padded orthogonally transformed block is subjected to an inverse orthogonal transformation to thereby restore the padded image block. Padding data contained in the restored padded image block is replaced with a portion obtained by copying a portion of the original image, thereby generating a modified image block. In a case where the true width of an edge pixel corresponding to an edge among the pixels forming the image block is less than 0.5, the pixel is obtained by adjusting the level of a pixel adjacent to the edge pixel in such a manner that it will have a level conforming to the width and level of the edge pixel.
    • 在通过对已经添加有填充数据的8×8像素的填充图像块进行正交变换而获得的填充正交变换块已被记录为压缩图像数据的情况下,将经填充的正交变换块进行逆正交变换 从而恢复填充的图像块。 包含在恢复的填充图像块中的填充数据被替换为通过复制原始图像的一部分而获得的部分,从而生成修改后的图像块。 在对应于形成图像块的像素中的边缘的边缘像素的真实宽度小于0.5的情况下,通过调整与边缘像素相邻的像素的电平来获得像素, 具有符合边缘像素的宽度和水平的水平。
