Therefore, according to the present invention, each user can modify the desired preference based on the selected preference (user characteristic information) designated by the user or the random preference automatically extracted based on the cumulative statistics (arbitrary user characteristic information) of the content used by the service. Multimedia content (image / audio / video / text content, etc.), that is, content that has been modified to reflect one's own interest, can be provided for playback service so that users can not only increase convenience (meaning universal multimedia access) but also various users Can effectively meet service needs.

Meanwhile, according to the multimedia content service method of the present invention, a preference for a content consumption method of a user is generated, and the content processing program is modified according to the original content and the specific consumption method based on the generated content consumption method of the user ( And a program or algorithm serving a service by transmitting the modified content processing program to the user in accordance with the modified content can be used by recording on a recording medium that can be mounted or mounted on a specific device. Can be read using.

On the other hand, according to a preferred embodiment of the present invention, when any terminal user requests a content service using metadata including user characteristic information and terminal characteristic information, the content server system processes the original content and the original content based on the metadata. Although the program has been described as being modified (adapted) and the modified adaptive content and the adaptive content processing program are transmitted to the corresponding user terminal requesting the service, the present invention is not necessarily limited thereto, and the user is not a content server system. Of course, the terminal may be configured to modify (adapt) the original content and the original content processing program based on the metadata.

In this case, it is not necessary to transmit metadata including user characteristic information and terminal characteristic information from the user terminal 110 side to the content server system 130 when requesting a content service, and the content adaptation block in the content server system 130. 133 and the content processing program adaptation block 134 transfer the original content and the original content processing program to the adaptive content and adaptive content processing program transmission block 136 without modification (adaptation). That is, the content server system 130 transmits the unmodified content and the content processing program to the user terminal 110.

On the other hand, in the adaptive content rendering block 117 in the user terminal 110 corresponds to the metadata provided from the user metadata generation and management block 112, that is, the content service request before rendering the content using the content processing program. Metadata including user characteristic information and terminal characteristic information is analyzed to modify (adapt) the content and the content processing program, and then adapt (content) the modified content using the modified (adapted) adaptive content processing program after such modification. As a result, the user can receive the modified content according to the metadata. To this end, the adaptive content rendering block 117 has a configuration that is the same as or similar to that shown in FIG. 3 and that modifies (adapts) the received content processing program based on the content processing program parameters.

Furthermore, the present invention designates a third terminal (arbitrary terminal) instead of its own terminal when the user requests the service of the content, inserts the terminal designation information into the content service request data, and delivers it to the content server system. The content server system may be configured to transmit the modified content and the modified content processing program (or unmodified original content and original content processing program) to any terminal designated by the user.

On the other hand, in one embodiment of the present invention, the content service request data including the user characteristic and the user terminal characteristic information as meta data is analyzed (interpreted), and the content and content processing program that has requested the service based on the analysis result. Although the present invention has been described as being modified (adapted) and then transmitted to a corresponding user terminal, the present invention is not necessarily limited thereto, and each content and content processing program to be serviced may be applied to various types of user characteristics and user terminal characteristic information.
