FIELD OF THE INVENTION 
     The present invention relates to a download method of media contents configured to allow an electronic book terminal to download various media contents such as books, newspapers, magazines, weeklies and monthlies. 
     DISCUSSION OF THE RELATED ART 
     In a case media contents such as books, newspapers, magazines, weeklies and monthlies are manufactured by media contents capable of providing through Internet, a manufacturing cost becomes reasonable, and sales can be promptly implemented through Internet upon editing. Furthermore, the media contents capable of providing through Internet have advantages of no burden of distribution and stock, and of fast planning and publishing catering to the trend of the times. Books, newpapers, magazines, weeklies and monthlies that have a small marketing scale can be easily published by media contents. 
     Furthermore, a user can perform text search through the media contents and utilize various functions by being connected to the Internet, and once the media contents are manufactured, the manufactured media contents can be perpetually marketed, thereby replacing paper-printed media at a fast pace to cope with an increase of population using the Internet and expansion of optical communication network. 
     In a case a predetermined media contents are downloaded through Internet, according to a conventional manner, an electronic book terminal used to be connected to a contents server in response to a user manipulation, and download was implemented after search of desired media contents. 
     However, the media contents such as newpapers, magazines, weeklies and monthlies that are published on a daily, weekly or monthly basis suffer from disadvantages in that a user must remember a publishing date, and connect to a contents server on the memorized publishing date to download the media contents. Another disadvantage is that the media contents can be used not only for a downloading electronic book terminal but also by any arbitrary electronic book terminal, failing to protect the media contents.

Furthermore, the electronic book terminal ( 100 ) may request the download of a predetermined media contents set up by the user for a periodic subscription at a preset time, and receive the media contents provided by the request. 
     Reference numeral  110  is a contents server, the contents server ( 110 ) may store a predetermined media contents and transmit to the electronic book terminal ( 100 ) the predetemined media contents which is requested to download by the electronic book terminal ( 100 ). Furthermore, the contents server ( 110 ) may provide an intrinsic DRM (Digital Right Management) code to each electronic book terminal ( 100 ). 
     Reference numeral  120  is a first communication network. The first communication network ( 120 ) may be, for example, an Internet where the electronic book terminal ( 100 ) and the contents server ( 110 ) are connected to the first communication network ( 120 ) to transmit a predetermined date therebetween. 
     Reference numeral  130  is a mobile communication terminal. The mobile communication terminal ( 130 ) may receive a message notifying the download of the media contents transmitted by the electronic book terminal ( 100 ) in a SMS (Short Message Service). Reference numeral  140  is a second communication network. The second communication network ( 140 ) may be, for example, a mobile communication network, where the contents server ( 110 ) and the mobile communication terminal ( 130 ) transmit to each other a message such as the SMS through the second communication network ( 120 ). 
     The download method applied to the abovementioned system according to the present invention is such that the electronic book terminal must be first registered with the contents server and the DRM code must be downloaded and stored. 
       FIG. 2  is an exemplary operation in which an electronic book terminal is registered on a contents server to download a DRM code in a download method of media contents according to an exemplary embodiment of the present invention. 
     Referring to  FIG. 2 , the electronic book terminal ( 100 ) may determine whether a command has been inputted from a user interface (UI, not shown) to connect to the contents server ( 110 ) (S 200 ). It it is determined that the command has been inputted to connect to the contents server ( 110 ), the electronic book terminal ( 100 ) may display an initial screen capable of inputting an ID (IDentification) and a password (S 202 ), and the ID and the password are inputted from the UI (S 204 ). 
     If the ID and the password are inputted, the electronic book terminal ( 100 ) may combine information of the electronic book terminal ( 100 ) with the ID and the password to generate a message (S 206 ). For example, the electronic book terminal ( 100 ) may combine information of a communication network including at least one of a serial number, an ESN (Electronic Serial Number), an IMEI (International Mobile Equipment Identity) and an MAC (Media Access Control) address with the ID and the password to generate a message.

If the message is received from the electronic book terminal ( 100 ), the contents server ( 110 ) may determine whether the electronic book terminal ( 100 ) is registered using the received message (S 210 ). 
     As a result of the determination, if the electronic book terminal ( 100 ) is not registered, the contents server ( 110 ) may store the message received from the electronic book terminal ( 100 ) and register (S 212 ), use the received message to generate the DRM code, and store the generated DRM code responsive to the message (S 214 ). 
     The contents server ( 110 ) may transmit the generated DRM code to the electronic book terminal ( 100 ) through the first communication network ( 120 ) (S 216 ). Successively, the electronic book terminal ( 100 ) may receive and store the DRM code (S 218 ), where the DRM code is generated by using the message received by the contents server ( 110 ), and each of the electronic book terminal ( 100 ) is provided with an intrinsic DRM code. 
       FIG. 3  is an exemplary operation in which an electronic book terminal downloads a predetermined media contents from a contents server and decodes the downloaded media contents with DRM code for displaying on a screen according to the present invention. 
     Referring to  FIG. 3 , the electronic book terminal ( 100 ) may determine whether a command requesting a media contents list has been inputted from the UI (S 300 ). 
     As a result of the determination, if the command requesting the media contents list has been inputted, the electronic book terminal ( 100 ) may generate a message notifying itself (S 302 ), and may transmit the generated message to the contents server ( 110 ) (S 304 ). That is, the electronic book terminal ( 100 ) may display an initial screen to receive the ID and the password from the UI, may combine the inputted ID and the password with the information of the electronic book terminal ( 100 ) to generate a pre-determined message and to transmit the generated message to the contents server ( 110 ). 
     The electronic book terminal ( 100 ) may request the media contents list of the contents server ( 110 ) (S 306 ). The contents server ( 110 ) may use the message received from the electronic book terminal ( 100 ) to determine whether the electronic book terminal ( 100 ) is a registered electronic book terminal ( 100 ) (S 308 ). 
     As a result of the determination, in case of registered electronic book terminal ( 100 ), the contents server ( 110 ) may determine the DRM code provided to a relevant electronic book terminal ( 100 ) (S 310 ), encode the media contents list by the DRM code (S 312 ), and transmit the DRM code to the electronic book terminal ( 100 ) (S 314 ). 
     The electronic book terminal ( 100 ) may receive the media contents list transmitted by the contents server ( 110 ) to decode the list in response to the DRM code (S 316 ), and display the media contents list on the screen to allow the user to check the media contents list (S 318 ). Under this circumstance, the electronic book terminal ( 100 ) may determine whether a command for selecting a predetermined media contents has been inputted from the UI (S 320 ). 
     As a result of the determination, if the command for selecting the predetermined media contents has been inputted, the electronic book terminal ( 100 ) may request purchase of relevant media contents of the contents server ( 110 ) (S 322 ) and pay an amount for purchase of the media contents by executing a payment process (S 324 ). At this time, the payment process is the conventional payment method, a detailed process of which is omitted. 
     In a case the payment process is completed, the contents server ( 110 ) may encode a relevent media contents in response to a relevant DRM code of the electronic book terminal ( 100 ) (S 326 ), and transmit the encoded media contents to the electronic book terminal ( 100 ) (S 328 ). The electronic book terminal ( 100 ) may download the media contents transmitted by the contents server ( 110 ) and determine whether an execution command for the downloaded media contents has been inputted (S 330 ). 
     As a result of the determination, if the execution command has been inputted, the electronic book terminal ( 100 ) may decode the downloaded media contents using the DRM code (S 332 ) and display the decoded media contents for the user to view (S 334 ). 
     DETAILED DESCRIPTION OF THE INVENTION 
       FIGS. 4 and 5  are exemplary operation in which a periodic subscription of media contents published on a periodic base is set up and downloaded in a download method of media contents according to the present invention. 
     Referring to  FIG. 4 , the electronic book terminal ( 100 ) may determine whether a command to connect to the contents server ( 110 ) has been inputted from the UI (S 400 ). As a result of the determination, if the command has been inputted, the electronic book terminal ( 100 ) may generate self-notifying message (S 402 ) and transmit the generated message to the contents server ( 110 ) (S 404 ). Successively, the contents server ( 110 ) may detemine using the message received from the electronic book terminal ( 100 ) whether the electronic book terminal ( 100 ) is the registered electronic book terminal ( 100 ) (S 406 ). 
     Under the state where the electronic book terminal ( 100 ) is registered with the contents server ( 110 ), the electronic book terminal ( 100 ) may transmit to the contents server ( 110 ) subscription setup information capable of periodically subscribing to a predetermined media contents that is periodically published including newspaper, a magazine, a weekly and a monthly, and set up a periodic subscription to the pre-detemined media contents (S 408 ). 
     Furthermore, the electronic book terminal ( 100 ) and the contents server ( 110 ) may perform a payment process to each other to pay the amount of media contents configured to set up the periodic subscription (S 410 ). 
     In a case the payment process is completed, the electronic book terminal ( 100 ) may set up time information configured to download the media contents set up for the periodic subscription, and a notification time information notifying the user that the media contents have been downloaded, in response to an operation command inputted from the UI (S 412 ). For example, the download time information including a date and a time to download the media contents, and the notification time notifying the user of the download of the media contents may be set up. 
     Furthermore, the electronic book terminal ( 100 ) may register the information of a mobile communication terminal ( 130 ) that notifies the user of the download of the media contents (S 414 ), and set up a wake-up time configurd to wake up itself for downloading of the media contents (S 416 ). At this time, the wake-up time may not be separately set up but be set up by time information configured to download the media contents. 
     Under this circumstance, the electronic book terminal ( 100 ) may determine whether time has matured for set-up wake up time (S 418 ). As a result of the determination, if the time has matured, the electronic book terminal ( 100 ) may be woken up (S 420 ), and connected to the contents server ( 110 ) through the first communication network ( 120 ) to transmit a message for notifying self information (S 422 ) and to request download of media contents that is set up for periodic subscription (S 424 ). 
     Successively, the contents server ( 110 ) may determine whether the electronic book terminal ( 100 ) is an electronic book terminal ( 100 ) registered by the message received from the electronic book terminal ( 100 ) and whether the media contents set up for periodic subscription has been registered (S 426 ). 
     As a result of the determination, if the electronic book terminal is the registered electronic book terminal ( 100 ), and if the media contents set up for periodic subcription has been registered, the contents server ( 110 ) may detemine a relevant DRM code provided to the electronic book terminal ( 100 ) (S 428 ). 
     In the case that the DRM code is determined, as illustrated in  FIG. 5 , the contents server ( 110 ) may encode the media contents set up for the periodic subscription using the DRM code (S 430 ) and transmit the encoded media contents to the electronic book terminal ( 100 ) (S 432 ). 
     The electronic book terminal ( 100 ) may receive and store the media contents transmitted by the contents server ( 110 ) (S 434 ), and transmit a message to the contents server ( 110 ) notifying that the download of the media contents have been completed in a case the media contents have been completed in downloading (S 436 ). Successively, the electronic book terminal ( 100 ) may determine whether time has matured for the set-up notification time (S 438 ). 
     As a result of the determination, if the set-up notification time has arrived, the electronic book terminal ( 100 ) may transmit to the mobile communication terminal ( 130 ) a message by SMS, notifying that the download of the media contents have been completed (S 440 ). Furthermore, the electronic book terminal ( 100 ) may determine whether an execution command has been inputted from the UI (S 442 ), decode the downloaded media contents by the DRM code in a case the execution command has been inputted (S 444 ), and display the decoded media contents on the screen to allow the user to check the media contents (S 446 ). 
     The download method of media contents according to the present invention has an industrial applicability in that information configured to download media contents such as newspaper, a magazine, a weekly and a monthly is pre-stored, and relevant media contents are requested and downloaded at a date and a time based on the downloaded information, whereby the user is free from personally downloading the media contents.
