Description:
FIELD OF THE INVENTION  
       [0001]     The present invention relates to a content unity control method for using signal system to control the unities of contents that are used through the physical support of wired/wireless internet, Mobile, PDA, DMB, PSP, etc. Particularly the present invention is intended to minimize the physical, time and space limits while the user is using contents after going through the established authentication procedures and support a satisfactory content service so that the user may get the contents that he wants at any time and any place, and, at the same time, provide an identical and unified interface so that the user may accomplish content unity search and user administration with ease and also approach efficiently to the registered data statistics together with its applications.  
       BACKGROUND OF THE INVENTION  
       [0002]     The conventional system for the unity control of digital content adopted an integrative solution developed on the wired/wireless internet basis. Accordingly, in case where the user uses contents through the physical support of the conventional Mobile, PDA, DMB, PSP, etc., there were many disadvantages in the integrative control of wired/wireless internet such as the difficulty in approaching contents, the problem of one-way transfer, etc.  
       SUMMARY OF THE INVENTION  
       [0003]     The present invention is intended to overcome the disadvantages of the conventional technique. Therefore, it is an object of the present invention to modularize various index screens (initial screens) so that the design skin of index screen can be easily altered in the administrator&#39;s mode without a separate customizing, and also to enable for the administrator to alter accordingly to the institutional peculiarities in the variable, not fixed, field in case of the main category.  
         [0004]     It is another object of the present invention to use the physical support (wired/wireless internet, Mobile, PDA, DMB, PSP, etc.) with LCMS (Learning Content Management System) and LMS (Learning Management System) installed on and connected to the personal mini homepage (blog) so that the user may use and administrate the content, thereby receiving a royal welcome from the user.  
         [0005]     As to the content, irregardless of the physical support, a device of interface for the respective physical support is provided to heighten the accessibility to the content, and it is possible to download contents without a separate telecommunicative link in an approach through the wired/wireless internet with such a terminal device as Mobile, PDA, DMB, PSP, etc.
