FIG. 4 is a flowchart of a method for implementing a mobile terminal browsing multimedia resources, that is, a method for implementing page adaptation according to an embodiment of the present invention. As shown in FIG. 4, the method for implementing page adaptation in this embodiment includes the following steps:

5301. The page adaptation system receives a page access request sent by the mobile terminal.

The request, the page access request message generally includes at least the URL that the user wants to access, the type and model of the mobile terminal. The page access request indicates that the user wants to access the resource specified by the URL, but the resource specified by the URL may be a traditional HTML page for the PC, that is, may not be suitable for direct browsing and display by the mobile terminal, or may be a multimedia such as a large picture. Information, not suitable for transmission and download directly on the mobile network.

5302: Obtain a corresponding multimedia resource from the corresponding WWW server; the page adaptation system analyzes the URL in the page access request, and initiates a new Hypertext Transfer Protocol (HTTP) link to the corresponding WWW server according to the URL, Obtain the corresponding multimedia resource from the host specified by the URL. S303. Analyze whether the acquired multimedia resource is applicable to the corresponding mobile terminal.

The page adaptation system analyzes whether the multimedia resource is universal or suitable for general mobile terminal browsing and use, for example, a WML page or an XHTML page that is already suitable for mobile terminal browsing, or has a smaller image suitable for mobile terminal access. For multimedia resources, no conversion adaptation is required.

Whether the media resources are universal or not is generally judged according to experience. For example, most mobile phones support JPG format pictures, but they do not necessarily support PNG format pictures. The same WAV format audio is generally supported, but MP3 format audio is not. Must support.

S304, judging whether the conversion is needed according to the preliminary analysis conclusion, if no conversion is needed, for example, if the image is already a small and common image, then the process is not required to be converted, then the process goes to S305, otherwise, the process proceeds to S306.

S305. The obtained multimedia resource is sent to the corresponding mobile terminal. After the page adaptation system sends the data packet corresponding to the acquired multimedia resource to the mobile terminal of the user, the corresponding connection is released, and the process ends. S306, determining whether media processing is required, if necessary, moving to S307, otherwise steering

S308;

The page adaptation system determines whether media processing is required according to the capability information and system configuration information of the corresponding mobile terminal and the corresponding media resource data packet. The capability information of the mobile terminal mainly refers to: the display size of the terminal, the supported picture and the audio and video format. The system configuration information mainly refers to: Some common parameters and settings, such as how much size can be specified in the configuration mode to require media processing.

When the multimedia resource is in the picture or audio and video format, but is not supported by the mobile terminal, the picture or audio and video format of the multimedia resource needs to be converted into a picture or audio and video format supported by the mobile terminal.

S307, performing media processing; Specifically, the image may be subjected to format conversion, size conversion, and audio and video editing to meet the capability requirements of the mobile terminal, and the processed multimedia resource data packet is delivered to the adaptation module.

For example, if the mobile terminal only supports pictures in JPG format and the acquired multimedia resource is a GIF picture, then the GIF picture needs to be converted into a JPG picture.

5308. Perform a scan analysis on the markup language to determine whether markup language processing is required. If necessary, go to S309, otherwise, go to S310. Specifically, the page adaptation system scans and analyzes the markup language of the received multimedia resource to determine the move. Whether the terminal supports the markup language of the multimedia resource, if the corresponding mobile terminal does not support the markup language of the multimedia resource, the markup language of the multimedia resource needs to be processed into a markup language supported by the corresponding mobile terminal.

For example, the mobile terminal supports Extensible Hypertext Markup Language (XHTML), and the markup language of the multimedia resource is Hyper Text Markup Language (HTML), which will need to convert the HTML of the multimedia resource into XHTML supported by the mobile terminal. .

5309, performing regularization and conversion of the markup language;

The page adaptation system performs the markup language regularization and conversion work according to the capability information of the corresponding mobile terminal (for example, the markup language type and version supported by the mobile terminal) and the multimedia resource data package, and appropriate system configuration information. For example, the page adaptation system regulates or converts traditional HTML, if the mobile terminal supports

XHTML analyzes and regularizes HTML into XHTML. If the mobile terminal only supports WML, it converts HTML into WML.

5310: Send the processed data packet of the multimedia resource to the corresponding mobile terminal; the page adaptation system sends the data packet of the multimedia resource processed by the media processing and the markup language to the corresponding mobile terminal, and ends the process. In summary, the system and method for page adaptation according to the embodiment of the present invention can solve the problem that mobile terminals with different capabilities access the traditional PC-designed pages of the Internet, greatly improving the user experience and greatly reducing the user experience. Manually adjust the amount of work on the page.

It is a matter of course that the invention may be embodied in various other forms and modifications without departing from the spirit and scope of the invention.

Industrial Applicability The present invention enables a mobile terminal of different capabilities to access a conventional Internet page with a good user experience and greatly reduces the workload of manually adjusting the page. It makes it easier for mobile terminals to access traditional Internet pages, and it is more in line with the capabilities of each terminal, or a better user experience.
