The value of the information on the performance of the terminal, information on the user context and information on the service policy is expressed by at least one of Boolean, string, and numeric.

In operation S540, the applications SAML_C1, SAML_C2, and SAML_C3 optimized for the terminals 200_1, 200_2, and 200_3 are serviced. The application SAML_C1, SAML_C2, and SAML_C3 may be configured of at least one of XHTLM, HTML, JAVA, and Flash.

For example, the server 100 may have a workbook SAML_S composed of components a to z. The server 100 receives the first characteristic information DC_1 from the first terminal 200_1, parses the first characteristic information DC_1, and numeric the resolution and processing capability of the first terminal 200_1. It can be recognized through the value expressed as). Then, by selecting and extracting the components a, d and x that are playable and processable at the resolution of the first terminal 200_1 in the workbook SAML_S, an application SAML_C1 composed of the components a, d and x is generated. This may be transmitted to the first terminal 200_1.

Alternatively, the server 100 receives the second characteristic information DC_2 from the second terminal 200_2, parses the second characteristic information DC_2, and generates an OS name, a user name, and a name of the terminal of the second terminal 200_2. Supported languages can be recognized through string values. Then, components a, b, c, and y that are reproducible and processable in the OS name, the user name, and the supported language of the second terminal 200_2 are selected and extracted from the workbook SAML_S. An application SAML_C2 composed of c and y may be generated and transmitted to the second terminal 200_2.

Alternatively, the server 100 receives the third characteristic information DC_3 from the third terminal 200_3 and parses the third characteristic information DC_3 to determine whether the third terminal 200_3 is mounted with GPS, whether content is limited, and the like. This can be recognized by a Boolean value. And, the application consisting of components a, f, g by selecting and extracting the components a, f, g that can be played back and processed according to whether the third terminal 200_3 is equipped with GPS or whether content is limited in the workbook SAML_S. SAML_C3 may be generated and transmitted to the third terminal 200_3.

In this way, the server 100 according to the characteristics of each of the terminals (200_1, 200_2, 200_3), each terminal (200_1, 200_2, 200_3) can be reproduced in one workbook (AMML_C1, SAML_C2, SAML_C3) optimally SAML_S) selects, extracts, and provides some components, so that one application can be shared in an optimized state in each of the terminals 200_1, 200_2, and 200_3. Herein, the integrated document SAML_S is newly defined by the present applicant and is written in a markup language, and components corresponding to the characteristic information DC_1, DC_2, and DC_3 of all terminals 200_1, 200_2, and 200_3 are one. Since it is integrated into a document, the server 100 can select and extract at least a part from the workbook (SAML_S) according to the characteristic information (DC_1, DC_2, DC_3) of each terminal (200_1, 200_2, 200_3), That is, since the workbook SAML_S is scalable, the workbook SAML_S is hereinafter referred to as a scalable application markup language (SAML) document.

Hereinafter, an example of a method in which the server 100 efficiently services the applications SAML_C1, SAML_C2, and SAML_C3 optimized to each terminal 200_1, 200_2, and 200_3 using the SAML document SAML_S is described.

The server 100 may grasp characteristic information DC_1, DC_2, and DC_3 received from each terminal 200_1, 200_2, and 200_3, and classify each terminal 200_1, 200_2, or 200_3 into any one of preset classes. have. For example, the server 100 may be one of the first class of the base profile, the second class of the main profile, and the third class of the high profile. , 200_3). Here, each class may be classified according to the performance and / or resolution of the terminals 200_1, 200_2, and 200_3. For example, the first class of the base profile may correspond to the performance and resolution of the mobile device, the second class of the mail profile may correspond to the PC class device, and the third class of the high profile may correspond to the HD TV class device. The classification criteria are exemplary, and the criteria for classifying each class may be variously set according to the home network system.

The SAML document (SAML_S) integrates the components corresponding to each class. Accordingly, the server 100 classifies the class of each terminal 200_1, 200_2, 200_3 according to the characteristic information DC_1, DC_2, DC_3 received from each terminal 200_1, 200_2, 200_3, and corresponds to the classified class. The components may be selected and extracted from the workbook SAML_S to serve the applications SAML_C1, SAML_C2, and SAML_C3.

As such, the server 100 classifies each terminal 200_1, 200_2, and 200_3 into any one of the preset classes, and in the SAML document (SAML_S) in which components corresponding to each class are integrated, selects appropriate components based on the class. Can be selected and extracted easily and efficiently.

Meanwhile, the server of FIG. 4 will be described in detail with reference to FIG. 6.

Referring to FIG. 6, the server 100 may include a request processing unit 110, a client performance storage unit 120, an application loader 130, and a transcoding engine 140.

First, the request processor 110 receives a content request from the terminals 200_1, 200_2, and 200_3 and characteristic information DC_1, DC_2, and DC_3 of each terminal 200_1, 200_2, and 200_3. The request for content and the characteristic information DC_1, DC_2, and DC_3 of each terminal 200_1, 200_2, and 200_3 may be transmitted through, for example, the http protocol. The request processor 110 inquires the client performance storage unit 120 of a class to which each terminal 200_1, 200_2, 200_3 belongs using the characteristic information DC_1, DC_2, and DC_3 of the terminals 200_1, 200_2, and 200_3. can do. The request processing unit 110 provides the information of the class provided from the client performance storage unit 120 to the transcoding engine 140, which will be described later, so that the transcoding engine 140 can access the terminals 200_1, 200_2, and 200_3. It is possible to create an application (SAML_C1, SAML_C2, SAML_C3) suitable for. In addition, the request processing unit 110 may provide the application loader 130 with information about the content request.

The client performance storage unit 120 receives the characteristic information DC_1, DC_2, DC_3 from the request processing unit 110, extracts a parameter from the characteristic information DC_1, DC_2, DC_3, and uses the extracted parameter to determine the terminal ( 200_1, 200_2, 200_3) are determined. The parameter here represents the device performance factor and external environmental factor described above. That is, the client performance storage unit uses a parameter indicating a device performance factor and an external environmental factor, and for example, each terminal 200_1, 200_2, 200_3 may select one of the first class of the base profile, the second class of the mail profile, and the high profile. It determines whether it belongs to a class and provides information of the class to the request processing unit. In addition, the client performance storage unit in order to efficiently process the request of each terminal (200_1, 200_2, 200_3) in the future, information on the performance of each terminal (200_1, 200_2, 200_3), parameters or characteristic information (DC_1, DC_2, DC_3) Or store information about the class. For example, if the ID of each terminal 200_1, 200_2, 200_3 or the user information or characteristic information DC_1, DC_2, DC_3 of the terminals 200_1, 200_2, 200_3 are provided, the client performance storage 120 may perform no parameter extraction process. The class information of the terminals 200_1, 200_2, and 200_3 is immediately obtained based on the IDs of the provided terminals 200_1, 200_2, and 200_3 or the user information or the characteristic information DC_1, DC_2, and DC_3 of the terminals 200_1, 200_2, and 200_3. It may be provided to the request processing unit 110.

The application loader 130 retrieves and downloads a SAML document for the requested content, for example, the requested application SAML_C1, SAML_C2, or SAML_C3, using the information on the content request. For example, the application loader 130 may search for and download a SAML document corresponding to the requested application from various SAML documents stored on the web.
