In a sense, it provides a business model or business opportunity.
- the first server is a server that is connected to the Internet and is specially set up to manage the above embedded terminals.
- the first server differs from other servers connected to the Internet in that it not only has dedicated software to manage the embedded terminals, but also a dedicated database to support the above management.
- the S2 first server After receiving the request of the embedded terminal, the S2 first server verifies the request, and sends an authorized access address forming data packet of the embedded terminal to the terminal: the first server receives the embedded terminal After the request is sent, the request is first parsed, and the data is obtained, and it is determined that the request packet is sent by the terminal for the current request; and then the request is verified, for example, whether the terminal is authorized, and the authorized access address is those; If the terminal is illegal or has no right to issue the request, the first server returns a blank data packet, and ends the current request; otherwise, the authorized access address list address of the terminal is transmitted to the terminal, and the terminal selects.
- the authorized access address refers to an address that the first server allows the terminal to access, and the addresses are network addresses that are previously entered into the first server. The first server manages the terminal based on these addresses and the physical address of the terminal.
- the S3 embedded terminal parses the address data packet and selects one of the authorized access addresses: after receiving the address data packet sent by the first server, the embedded terminal parses the data packet, and lists the addresses. Displayed on the display of the digital photo frame for the user to select. Note that if the first server does not provide the above specific address list, that is, when the address packet sent back by the first server is blank, indicating the end If the service is illegal or not enabled, the user cannot perform address selection, and the embedded terminal cannot obtain data content on the network.

- the embedded terminal uses the selected address as the destination address, generates a data packet, and the third party server Establish a connection, and obtain the data content pointed to by the selected address in the server, and play or display the content on the display of the digital photo frame. For example, if a news is required, the video signal is transmitted to the display after the data format conversion is completed, so that it is displayed; the audio signal is transmitted to the speaker to make the speaker sound.
- the terminal acquires the data content, and only establishes a connection with the third-party server, and connects to the first server at the address where the data is obtained.
- the embedded terminal may establish a connection with the first server after acquiring the data, and the first server retrieves the data content required by the terminal from the network, and transmits the data content to the terminal after conversion.
- the traffic of the first server is increased in this way, the range of data taken by the above terminal can be expanded.
- step S1 further includes the following steps:
- the S11 embedded terminal calls up the first server request address stored therein as the content of the request packet, and forms a request packet to be sent to the first server: in this step, the terminal is in production
- the first server request address that has been solidified therein is used as the content of the data request packet, so that the first server can enter the corresponding address (request address) in the first server and receive corresponding content after receiving the data packet.
- the terminal is connected to the Internet by means of a wireless local area network (that is, the terminal is connected to the Internet via Wi-Fi), so the terminal can move freely without affecting the coverage of the wireless local area network. Its communication with the Internet.
- the first server requests the address to point to the request page of the first server, and when the first server resolves the first server request address by the data packet, enters the request page and performs the task of the page, that is, the terminal is verified. Request.
- the above first server request address and the tasks in the first server request page are all agreed in advance.
- step S2 further includes the following steps:
- the S21 first server parses the data packet sent by the terminal, and obtains the physical address of the terminal and the content in the data packet:
- the request sent by the terminal is transmitted to the Internet through the wireless local area network, so It must be a data packet that complies with the requirements of the local area network.
- the first server needs to parse the data packets to obtain the physical address of the terminal included in the data packet, and the terminal first server request address in the data packet or the terminal authorization included in the data packet. Enter the address.
- step S22 Is the content in the S22 packet the first server request address of the terminal?
- the first server needs to determine whether the content of the data packet obtained in the previous step includes the address of the first server requested by the terminal.
- the first server request address is set in advance, if the content in the data packet is the first The server requests the address, and step S23 is performed; otherwise, step S24 is performed.
- S23 compares the physical address of the terminal with the data in the user registration database in the first server, and obtains the root address of the authorized access address of the terminal:
- the first server calls up the user registration database located in itself. And comparing the terminal information currently obtained by parsing with the data in the user registration database to see if the parsed terminal information can be found in the user registration database, and if found, the requesting terminal is considered It is a legal terminal, and the first server needs to further find the user in the above-mentioned user registration database or a collection of all addresses that the terminal can browse (ie, authorized to access).
- the addresses exist in a tree structure, that is, corresponding to each terminal or user, the address that can be browsed is stored in categories, for example, the address that a terminal can browse includes news, sports, and finance.
- the news also includes the second-level classification of society and entertainment. In the social news category, it is divided into domestic and foreign countries, and so on, until the specific address corresponding to each news item. It can be seen that the above three categories of news, sports, and finance are the root addresses of the set of addresses that the terminal or user can browse (other addresses are subdivided from these three addresses; Note: The address described here The classification is an example for convenience of explanation, and may actually include more root addresses.
- step S25 the root address corresponding to the terminal that sent the request is taken out, and then step S25 is performed.
- the terminal is illegal or does not open the service for obtaining online data, the above root address is not available, that is, blank. The terminal still cannot browse the Internet.
- the hierarchical structure of the address may be understood by using a page in the Internet, where the root address corresponds to a front page unique to the terminal, and the home page has multiple address links (such as the above-mentioned financial, sports, news).
- each link corresponds to a second level page
- each second level page includes a plurality of third level links
- each third level address link corresponds to a third level page, and so on, up to the address
- the link corresponds to the specific data content.
- the address of the address link is the end address.
- the S24 first server searches for the user registration database thereon, finds the above authorized address location, and calls up the next-level classified address list included in the address: the first server has determined that the data packet is transmitted by the terminal.
- the content is not the first server request address of the terminal, but one of the addresses that the terminal can browse.
- the above address is found in the above-mentioned user registration database, and the next-level classified address included in the address is called.
- the S25 first server packs the called address data to form an address data packet and transmits the address data packet to the embedded terminal:
- the first server calls the foregoing terminal S23 or the above step S24, and the database and the terminal Request/or authorize the address associated with the address, and enter it into the data packet and pass it to the above terminal.
- the address in the address database of the first server may be input into the database, or may be collected by the first server on the Internet.
- the database may be dynamic or fixed. of. In this embodiment, the address database is input fixed content, and all of the above addresses exist in an RSS format.
- step S3 further includes the following steps:
- the S31 terminal parses the address data packet transmitted by the first server through the Internet, obtains a list of addresses included therein, lists it and displays it on the display screen of the terminal: In this step, the terminal receives the above steps.
- the data packet transmitted by the first server through the Internet the data packet needs to be parsed, and the data encapsulated in the request content is taken out.
- the address sent by the first server is in the RSS format (RSS Really SimpleSyndication describes and synchronizes the content of the website content), and in order to resolve the address, the terminal needs to call the RSS data format component. .
- RSS Really SimpleSyndication describes and synchronizes the content of the website content
- the ATOM Data Format component needs to be called. If there is only the RSS data format component in the terminal, the terminal can only parse the data packet whose address exists in the RSS format, and cannot parse the data packet whose address exists in the ATOM form. If we want a terminal to be able to resolve packets whose addresses exist in multiple data formats, then a corresponding plurality of data format components should be included in the terminal. After the terminal parses the address in the address data packet sent by the first server, the terminal displays the address on the display screen of the terminal for the user to select. [55] The S32 terminal selects an address in the above address list list: After the terminal displays the above address on its display screen, the user selects one of the displayed addresses.
- ATOM an XML-based document format and an HTTP-based protocol for aggregating web content
- step S33 terminal determines whether the above selected address is the end address?
- the address organization method on the first server is the one-level or multi-level branch address under the root address and the end address under the branch address (that is, the address is no longer included under it, but directly The address that points to the data content constitutes.
- step S35 it is judged whether the selected address is the end address, and if so, the jump proceeds to step S35; if not, step S34 is performed.
- the specific method for determining whether the selected address is the end address is as follows: First, the first server collects the address of the unified level in the organization address, for example, divides all kinds of addresses into three levels, The third level under the sports class address must be the end address, corresponding to the specific content; the third level under the news class address must be the end address, corresponding to the specific content; set in the embedded terminal, ie, the digital photo frame A flag bit, when the digital photo frame makes an initial value for each request, such as 3; secondly, in the process of requesting data in the digital photo frame, each time the end address is judged, the initial bit is decremented by 1, when the flag bit is 0 ⁇ , the address of this judgment is the end address; at the same time, the flag is restored to the initial value.
- the flag bit is also set in the digital photo frame, and the flag bit stores a specific value.
- the first server judges the address before sending the address data packet. If the address is an end address, a value corresponding to a specific value in the flag bit is placed at a specified position in the data packet, and after the digital photo frame receives and parses the data packet, the value is read at the specific position, such as It is equal to the value in the flag bit, and it is judged that the address is the end address; if it is not equal, it is judged that the address is not the end address.
- the address selected by the S34 terminal is sent into the data packet and sent back to the first server:
- the terminal since the terminal has judged that the selected address is not the end address, there must be a classified address under the address, now What the terminal needs is to obtain a further classified address under the address, and then the address is packaged and sent back to the first server, and the first server is notified to obtain the next-level address.
- the process returns to step S31, waiting for the response of the first server, and performing the next round of address selection and judgment.
- the S35 terminal extracts the specific content of the end address and establishes a connection with the first server or the third-party server, and obtains corresponding content corresponding to the address:
- the terminal has determined that the selected address is The end address corresponds to the specific data content.
- the terminal then invokes the peer-to-peer download tool, using the selected end address as the destination address, directly pointing to the selected address.
- the third-party server establishes a connection and downloads the content corresponding to the selected address.
- the above connection is established between the terminal and the third party server.
- the foregoing connection may also be established between the terminal and the first server, and the first server obtains the data content corresponding to the address, and then forwards the data content to the terminal after conversion or without conversion.

本发明的实施方式
[40] 如图 1所示, 在本发明一种嵌入式终端获取互联网上数据的方法及系统实施例 中, 其由互联网上获取数据的方法包括如下步骤:
[41] S1嵌入式终端通过其与互联网连接的无线接入点路由器向连接在互联网上的第
一服务器发出请求:在本步骤中, 嵌入式终端在用户的操作下发出需要取得数据 的请求, 该请求是一个数据包, 包括了请求源地址、 目的地址等数据, 其中, 源地址包括嵌入式终端的物理地址; 目的地址是第一服务器的地址, 该地址事 先存储在嵌入式终端内, 在需要发出请求吋调出使用, 所以, 该终端只能向上 述第一服务器发出请求。 上述请求通过连接在互联网和嵌入式终端之间的无线 接入点路由器发出。 当然, 上述第一服务器也是连接在互联网上的。 在本实施 例中, 第一服务器是作为一个连接上述终端和互联网之间的桥梁存在的, 缺少 了第一服务器, 终端就不能与互联网上的设备有效地通信。 这样做的好处是既 可以将许多与网络互联的功能转移到第一服务器上, 从而降低终端的成本, 又 可以有效地对上述终端进行管理, 使得单个终端对互联网的通信的效率得到进 一步的提高, 在某种意义上来讲, 提供了一种商业模式或商业机会。 值得一提 的是, 第一服务器是连接在互联网上、 为管理上述嵌入式终端而专门设置的服 务器。 第一服务器与其他连接在互联网上的服务器的不同之处, 在于其不仅有 专用的软件来完成对上述嵌入式终端的管理, 还有专用的数据库为上述管理提 供支持。
[42] S2第一服务器收到所述嵌入式终端的请求后, 验证该请求, 并将该嵌入式终端 的授权接入地址形成数据包发送到该终端: 第一服务器接收到上述嵌入式终端 发来的请求后, 首先解析该请求, 得到其中的数据, 确定是该终端本次请求所 发出的请求数据包; 然后验证该请求, 例如是否合法终端, 其授权接入地址是 那些等; 如果是终端非法或无权发出该请求, 第一服务器返回空白的数据包, 结束本次请求; 反之, 则将该终端的授权接入地址清单地址传送到该终端, 由 该终端选择。 在本实施例中, 上述授权接入地址是指上述第一服务器允许该终 端访问的地址, 这些地址是事先入上述第一服务器的网络地址。 第一服务器依 据这些地址及该终端的物理地址来管理终端。
[43] S3嵌入式终端解析所述地址数据包并在所述授权接入地址中选择一个: 嵌入式 终端收到第一服务器发来的地址数据包后, 解析该数据包, 将这些地址清单显 示在该数码相框的显示屏上, 供用户选择。 注意, 如果第一服务器没有提供上 述具体的地址清单, 即当第一服务器发回的地址数据包是空白的吋, 表明该终
端非法或未开通此服务, 用户无法进行地址选择, 该嵌入式终端不能获取网络 上的数据内容。
[44] S4嵌入式终端利用上述选择的地址, 与第一服务器或第三方服务器连接并取得 并显示或播放数据: 嵌入式终端将上述选择的地址作为目的地址, 生成数据包 , 与第三方服务器建立连接, 并取得该服务器中上述被选择地址指向的数据内 容, 将其内容在数码相框的显示屏上播放或显示。 例如, 如果要求的是一段新 闻, 则在完成数据格式转换后将其视频信号传送到显示屏上, 使其显示出来; 同吋将其音频信号传送到扬声器, 使扬声器发出声音。 在本实施例中, 终端在 获取数据内容吋仅只是与第三方服务器建立连接, 在获取数据所在地址吋与上 述第一服务器连接。 而在其他实施例中, 上述嵌入式终端在获取数据吋也可以 和第一服务器建立连接, 由第一服务器从网络上取回该终端所要求的数据内容 , 经过转换在传送给该终端。 虽然这样加大了第一服务器的流量, 但可以扩大 上述终端取的数据的范围。
[45] 在本实施例中, 如图 2所示, 上述步骤 S1进一步包括如下步骤:
[46] S11嵌入式终端调出其存放的第一服务器请求地址, 作为上述请求数据包的内 容, 形成请求数据包发送到所述第一服务器:在本步骤中, 将该终端在生产吋就 已固化在其中的第一服务器请求地址作为数据请求数据包的内容, 使得第一服 务器在接收到该数据包吋, 能够进入到上述第一服务器中的相应地址 (请求地址) 中并釆取相应的、 事先约定的动作。 在本实施例中, 上述终端是以无线局域网 的方式连接在互联网上的 (即上述终端与互联网通过 Wi-Fi连接), 所以在无线局 域网的覆盖范围内, 该终端可以任意移动而不会影响其与互联网的通信。 值得 一提的是, 第一服务器请求地址指向第一服务器的请求页面, 当第一服务器由 数据包中解析得到第一服务器请求地址吋, 进入请求页面并执行该页面的任务 , 即验证该终端的请求。 上述第一服务器请求地址以及第一服务器请求页面内 的任务, 都是事先约定好的。
[47] 在本实施例中, 如图 3所示, 上述步骤 S2进一步包括如下步骤:
[48] S21第一服务器解析终端发来的数据包, 得到终端物理地址及数据包中的内容: 在上述步骤 S12中, 终端发出的请求是通过无线局域网传递到互联网上的, 所以
其一定是符合局域网的规定的数据包。 第一服务器收到这些数据包后, 需要将 其解析, 从而得到包含在数据包内的终端的物理地址以及该数据包中的终端第 一服务器请求地址或包括在上述数据包中的终端授权接入地址。
[49] S22数据包中的内容是否终端的第一服务器请求地址?第一服务器需要判断上 一步骤中得到的数据包的内容中是否包括终端第一服务器请求地址。 在本步骤 中, 由于终端传来的数据包的内容不是第一服务器请求地址就是终端授权接入 地址, 而第一服务器请求地址是事先已设定好的, 如果数据包中的内容是第一 服务器请求地址, 执行步骤 S23;否则, 执行步骤 S24。
[50] S23比较终端物理地址和第一服务器中用户注册数据库中的数据, 得到该终端 分级的、 授权接入地址的根地址: 本步骤中, 第一服务器调出位于其本身的用 户注册数据库, 并将当前通过解析而得到的终端信息与上述用户注册数据库中 的数据相比较, 看看是否能在上述用户注册数据库中找到解析出来的终端信息 , 如果能找到, 则认为该发出请求的终端是合法终端, 第一服务器需要进一步 找到上述用户注册数据库中的该用户或该终端所能浏览的 (即授权接入的)所有地 址的集合。 在第一服务器中, 这些地址以树状结构存在, 即对应于每个终端或 用户, 其可以浏览的地址是分类保存的, 例如, 某终端可以浏览的地址包括新 闻、 体育和财经三大类, 而新闻又包括社会、 娱乐等第二级分类, 在社会新闻 类中又分为国内、 国外等, 如此直到具体的每条新闻所对应的具体地址。 可以 看到, 上述的新闻、 体育、 财经三大类就是该终端或用户所能浏览地址集合的 根地址 (其他地址都是又这三个地址细分而来的; 注意: 此处所描述的地址分类 是为了便于说明而举的例子, 实际上可以包括更多的根地址), 本步骤中, 就是 取出发来请求的终端所对应的上述根地址, 然后执行步骤 S25。 值得一提的是, 在本步骤中, 如果终端是非法的或未开通获取网上数据的业务, 则上述根地址 是没有的, 即空白的。 该终端依然不能上网浏览。 在本实施例中, 可以用互联 网中的页面来理解上述地址的分级结构, 上述根地址对应于该终端所独有的首 页, 该首页上有多个地址链接 (如上述的财经、 体育、 新闻), 每个链接对应于一 个第二级页面, 每个第二级页面有包括多个第三级链接, 每个第三级地址链接 有对应于一个第三级页面, 以此类推, 直到地址链接对应的是具体的数据内容
, 该地址链接的地址就是末端地址。
[51] S24第一服务器搜索其上的用户注册数据库, 找到上述授权地址位置, 并调出 该地址所包括的下一级分类地址清单:第一服务器已判断出由终端传来的数据包 中的内容不是终端的第一服务器请求地址, 而是上述终端可浏览的地址中的一 个。 在本步骤中, 就是在上述用户注册数据库中找到上述地址, 并调出该地址 所包括的下一级分类地址。
[52] S25第一服务器将调出的地址数据打包形成地址数据包传送到嵌入式终端: 在 本步骤中, 第一服务器将上述步骤 S23或上述步骤 S24调出的、 其数据库中与上 述终端请求 /或授权地址相关的地址, 并将其打入数据包中, 传递给上述终端。 在上述第一服务器的地址数据库中的地址, 可以是输入到该数据库中的, 也可 以是第一服务器平吋在互联网上收集而来的, 自然该数据库可以是动态的, 也 可以是固定内容的。 在本实施例中, 该地址数据库是输入的固定内容的, 且上 述所有地址是以 RSS格式存在的。
[53] 在本实施例中, 如图 4所述, 上述步骤 S3进一步包括如下步骤:
[54] S31终端解析由第一服务器通过互联网传来的地址数据包, 得到其中包括的地 址清单, 将其列表并显示在终端的显示屏上: 在本步骤中, 终端接收到在上述 步骤中由第一服务器通过互联网传来的数据包后, 需要解析该数据包, 取出封 装在其中的、 代表请求内容的数据。 如上所述, 在本实施例中, 第一服务器发 来的地址是以 RSS格式存在的 (RSSReallySimpleSyndication描述和同步网站内容 的一种格式), 为解析出该地址, 上述终端需要调用 RSS数据格式组件。 在其他 实施例中, 如果地址不是以 RSS格式存在, 则需要调用其相对应的数据格式组件 来判断。 例如, 如果该地址是以 ATOM格式存在 (ATOM—种基于 XML的文档格 式及基于 HTTP的协议, 用于聚合网络内容), 则需要调用 ATOM数据格式组件。 如果终端中只有 RSS数据格式组件, 则该终端只能解析其中的地址以 RSS格式存 在的数据包, 而不能解析其中的地址以 ATOM形式存在的数据包。 如果我们希望 一个终端可以解析地址以多种数据格式存在的数据包, 则在终端内应包括相应 的多种数据格式组件。 终端将第一服务器发送来的地址数据包中的地址解析出 来后, 将该地址显示在该终端的显示屏上, 供用户选择。
[55] S32终端选择上述地址清单列表中的一个地址: 终端将上述地址显示在其显示 屏上后, 用户选择该被显示的地址中的一个。
[56] S33终端判断上述选择的地址是否是末端地址?在前面的描述中, 已提到在第 一服务器上的地址组织方法是由根地址下的一级或多级分支地址以及分支地址 下的末端地址 (即其下不再包括地址, 而是直接指向数据内容的地址)构成。 在本 步骤中, 判断上述被选择的地址是否末端地址, 如是, 跳转执行步骤 S35 ; 如不 是, 执行步骤 S34。 在本实施例中, 被选择地址是否末端地址的判断的具体方法 如下: 首先第一服务器在组织地址吋将地址釆取统一级数的分级, 例如, 将所 有种类的地址均分为 3级, 体育类地址下的第三级一定是末端地址, 对应于具体 的内容; 新闻类地址下的第三级一定是末端地址, 对应于具体的内容; 在所述 嵌入式终端, 即数码相框内设置一标志位, 当数码相框进行每次请求吋设置一 个初始值, 如 3 ; 其次, 在数码相框请求数据的过程中, 每进行一次末端地址判 断, 将该初始位减 1, 当该标志位为 0吋, 本次判断的地址就是末端地址; 同吋 , 将该标志位恢复到初始值。 在其他实施例中, 也可以釆用别的判断方法, 例 如, 同样在数码相框中设置标志位, 该标志位中存放一个特定值, 第一服务器 在发出地址数据包之前先对该地址进行判断, 如该地址是末端地址, 则在该数 据包中的指定位置放置与上述标志位中特定值相同的值, 数码相框接收并解析 该数据包后, 在该特定的位置读出其值, 如与标志位中的值相等, 判断为该地 址是末端地址; 如果不相等, 则判断为该地址不是末端地址。
[57] S34终端选择的地址打入数据包, 并发回所述第一服务器: 在本步骤中, 由于 该终端已判断上述被选择的地址不是末端地址, 该地址下一定还有分类地址, 现在终端需要的是取得该地址下面的进一步的分类地址, 于是将该地址打包发 回第一服务器, 通知第一服务器, 以便取得下一级地址。 完成本步骤后, 返回 步骤 S31, 等待第一服务器的应答, 进行下一轮的地址选择和判断。
[58] S35终端取出该末端地址之具体内容并与所述第一服务器或第三方服务器建立 连接, 取得该地址所对应的相应内容: 在本步骤中, 该终端已判断出被选择的 地址是末端地址, 对应于具体的数据内容。 于是该终端调用其中的点对点下载 工具, 使用上述被选择的末端地址作为目的地址, 直接与上述被选择地址指向
的第三方服务器建立连接, 下载该被选择地址所对应的内容。 在本实施例中, 上述连接是建立在上述终端和第三方服务器之间的。 在其他实施例中, 上述连 接也可以建立在上述终端和第一服务器之间, 由第一服务器去获取该地址对应 的数据内容后, 再经过转换或不经转换转发给上述终端。
[59] 此外, 上述连接一旦建立, 如果上述被选择的地址对应的是连续内容, 则该连 接将被一直保持, 直到该终端所请求的内容被传递完毕。
[60] 在本实施例中, 上面所述的终端是一个数码相框, 当然在其他实施例中, 也可 以是别的数码设备或嵌入式设备。 在本实施例的描述中, '终端 '与'嵌入式终端'意 义相同。
[61] 图 5示出了本发明一种嵌入式终端获取互联网上数据的方法及系统实施例中的 系统结构示意图, 如图 5所示, 在本实施例中, 该系统包终端 1、 连接终端 1与互 联网 4的无线接入点路由器 2、 连接在互联网 4上的第一服务器 3和第三方服务器 5 , 其中, 终端 1用于向所述第一服务器 3发出请求, 接收并显示来自互联网的信 号; 第一服务器 3用于接收并验证所述终端 1发来的请求、 向所述终端 1发送其有 权浏览的网络数据所在的地址。 当第三方服务器 5发送到终端 1的请求内容吋, 并不经过上述第一服务器 3, 而是通过互联网 4和无线接入点路由器 2将所述内容 直接发送到所述终端 1(上述终端 1与第三方服务器 5在第一服务器 3的帮助下建立 了连接)。 在本实施例中, 由图 5中的终端 1所包括的 WiFi模块、 WiFi接入点 (即无 线接入点路由器 2)形成终端 1与互联网 4的连接, 并且, 上述终端 1的主体是一个 数码相框。
[62] 图 6是上述终端 1(数码相框)的结构示意图。 如图 6所示, 该终端 1(数码相框)包 括如下组成部分: 包括 Wi-Fi模块 14、 RSS处理模块 13、 数码相框主体 11以及设 置于数码相框主体 11的显示屏 111和扬声器 112, 其中所述 Wi-Fi模块 14用于在所 述数码相框 (终端 1)和无线接入点路由器 2之间通信; 所述 RSS处理模块 13用于将 第一服务器 3传送来的地址解析出来, 显示在数码相框的显示屏上供用户选择。 终端 1在获取到要求的数据后, 将其传送到显示屏 111和扬声器 112播放或显示。 在本实施例中, 该终端 1包括 RSS处理模块 13, 所以其只能解析 RSS数据格式的 地址; 在其他实施例中, 终端 1也可以包括 ATOM处理模块或包括 RSS处理模块
和 ATOM处理模块, 这样, 该终端 1就可以接收并解析 ATOM数据格式或 RSS数 据格式和 ATOM数据格式的地址。
[63] 图 7是上述第一服务器 3的结构示意图。 如图 7所示, 该第一服务器 3还包括用户 注册数据库 33 ; 所述用户注册数据库 33用于存放用户相关信息, 包括终端物理 地址以及该终端可以浏览的网络地址。 在其他实施例中, 第一服务器 3还包括内 容提供数据库, 所述内容提供数据库用于存放所述第一服务器 3应所述终端请求 , 由网络上获取并转发到所述终端的内容。 上述用户注册数据库 33和内容提供 数据库都通过第一服务器 3的总线 32与处理器 31相连, 便于调用。
