The support control module 110 supports the terminal 200 connected to the peripheral control module 150. The support control module 110 may download the update program to the terminal 200 for maintenance and function update of the terminal 200 and download the updated program to the terminal 200 for viewing or listening to the video and / And downloading a reproducible data file to the server. In addition, the support control module 110 performs registration of the user information through the communication module 170, and downloads of the update program and the reproducible data file. The support operation of the support control module 110 will be described in detail through the flowchart shown in FIG. In addition to the support operations, the support control module 110 controls the video controller 120, the main memory 130, the hard disk 140, the input controller 150, the peripheral control module 160 and the communication module 170, Performs operations of data and logic. The support control module 110 includes a North Bridge 114 and a South Bridge 116 connected in series to a Central Processing Unit ).

The CPU 112 downloads the update program to the terminal for maintenance and function update of the terminal 200 and downloads the reproducible data file to the terminal 200 for viewing or listening to the video and / And so on. Also, the CPU 112 performs registration of user information, download of a program for updating and download of a reproducible data file through the communication module 170. [ In addition, the CPU 112 includes a north bridge 114, a south bridge 116, a video controller 120, a main memory 130, a hard disk 140, an input controller 150, a peripheral control module 160, And the communication module 170, and performs data operation and logical operation. To this end, the CPU 112 includes an arithmetic logic unit (ALU), a control unit, a register, a storage device interface, and the like.

The north bridge 114 relays bi-directional data communication between the video controller 120 and the main memory 130, which are relatively fast peripherals including the south bridge 116, and the CPU 112, respectively. Under control of the CPU 112, the north bridge 114 controls the video controller 120, the main memory 130, and the south bridge 116.

The south bridge 116 is a kind of register set that manages the input and output of each of the relatively slow peripheral devices. The south bridge 116 is connected to the CPU 112 connected to the hard disk 140, the input controller 150, the peripheral control module 160, and the communication module 170 via the north bridge 114, Relay the transmission. In addition, the south bridge 116 is connected to the hard disk drive 140, the input controller 150, the peripheral control module 160, and the communication module 160 under the control of the connected CPU 112 via the north bridge 114 (170). To this end, the south bridge 116 is connected to the north bridge 114 by a PCI bus (not shown).

The video controller 120 causes the data processed by the support control module 110 (i.e., the CPU 112) to be displayed on a display device such as a cathode ray tube or LCD (Liquid Crystal Display) panel. To this end, the video controller 120 may be coupled to the north bridge 114 by an AGP (Accelerated Graphic Port).

The main memory 130 provides a work space for the support control module 110, specifically, the CPU 112. In other words, the main memory 130 temporarily stores data to be processed or processed by the CPU 112 in the support control module 110. To this end, the main memory 130 is connected to the north bridge 114.

The hard disk 140 stores various programs including an operating system (OS). System programs such as an operating system and various application programs may be stored in a separate memory called a ROM. The operating system stored in the hard disk 140 is uploaded to the main memory 130 by the system boot operation and is executed. Various application programs stored in the hard disk 140 are uploaded to the main memory 130 at the user's choice and executed.

The input controller 150 transmits data input through an input device such as a keyboard and a mouse to the CPU 112 via the south bridge 116 and the north bridge 114.

The peripheral control module 160 controls data input / output between the support system and the terminal 200. In other words, the peripheral control module 160 relays bidirectional data transmission between the support control module 110 (specifically, the CPU 112) and the terminal 200 to be supported. The connection between the peripheral control module 160 and the terminal 200 may be performed by various interface devices. However, in the present invention, the peripheral control module 160 is connected to the peripheral control module 160 through the universal serial bus (USB) To be supported by the terminal 200 to be supported will be described as an example.

The communication module (170) relays bidirectional communication between the supporting system and the communication network. More specifically, the communication module 170 transmits data from the public telephone network or the local area network to the support control module 110 (i.e., via the south bridge 116 and the north bridge 114 to the CPU 112) Or transmits data from the support control module 110 (i.e., transmitted from the CPU 112 via the north bridge 114 and the south bridge 116) to the public switched telephone network or the local area network. To this end, the communication module 170 is connected to the south bridge 116 by PCI or USB.

The terminal 200 connected to the peripheral control module 160 may be a mobile phone, a portable receiver portable player, a portable phone having a playback function, a portable receiver (PDA, PMP, MP3 player, etc.).

Hereinafter, the configuration of the terminal together with the terminal support system will be described in detail with reference to FIG.

In FIG. 2, the configuration of the terminal support system has been described in detail with reference to FIG. 1, and therefore only important components will be described.

As shown in FIG. 2, the terminal support system 100 includes a support control module 110, as shown in FIG. A connection interface 180 is connected to the peripheral control module 160 connected to the south bridge 116 of the support control module 100. The connection interface 180 allows data communication between the terminal 200 and the terminal support system 100 so that a USB interface device can be applied.

Meanwhile, the terminal 200 includes a main controller 210 for controlling the operation of the terminal. The main controller 210 stores the data file transmitted from the terminal support system 100 in the storage unit 230 and reproduces the stored data file when there is a playback request from the user. Hereinafter, the method of reproducing the data file will be described in detail while explaining the operation of the present invention.

The main controller 210 is provided with a connection interface 280 for enabling data communication with the terminal support system 100 corresponding to the connection interface 180. Accordingly, if the connection interface 180 is a USB interface device, the connection interface 280 is also a USB interface device.

The main controller 210 is connected to an output unit 220 for displaying the data file transmitted from the terminal support system 100 to the user. The output unit 220 may include a video output unit and an audio output unit. The video output unit may include various display devices such as an LCD and a PDP.

Meanwhile, the main controller 210 is provided with a storage unit 230 for storing the data file transmitted from the terminal support system 100. In addition, the storage unit 230 stores a characteristic table storing characteristics of the terminal.

FIG. 3 shows an example of a feature table applied to a specific embodiment of the present invention.

As shown, the feature table includes basic information, user information, and DRM information. Basic information includes manufacturer, model name, product type, product identification number, serial number, part number, and OS program version. The user information includes a user name, a user access number, and a user password. This user information is recorded by the user. The DRM information includes data on DRM means capable of releasing among various DRM means according to the creator of the data file of the video and / or audio information. In addition to these basic information, user information and DRM information, possible initial language, codec information, display information, frequency modulation information, recording function, sound effect, kind of recording medium and battery support information may be included.

As shown in FIG. 3, display information and caption information are stored in the feature table. The display information and the caption information are data for optimizing the caption file to a portable device, and the display information includes information on the type, resolution, and size of the display. In the caption information, supportable file format information in the form of a caption file supported by the portable device, caption size, caption color, and font information are stored.

Therefore, when the subtitle file is transmitted to the terminal 200, the support control module 110 first searches the subtitle information and changes the format of the subtitle file in the format stored in the subtitle information. At this time, if the format of the subtitle file is not supported by the portable terminal, it may be converted into a format supported by the terminal 200.

However, if the caption information can not be obtained, the format of the caption file is converted through the display information. That is, the proper format of the subtitle file is set in consideration of the display resolution and the size.

Meanwhile, the support control module 110 checks whether the connected terminal 200 is a terminal supporting the subtitle file. If the terminal 200 does not support the subtitle file (for example, it does not support devices such as MP3) , The converted subtitle file is combined with a moving image file (hereinafter referred to as a combined file). At this time, it is preferable that the subtitle file is pasted to the moving picture file using a filter.

In addition, the support control module 110 is a terminal supporting the subtitle file, and the file data (referred to as a video file) to be transmitted can be converted and the subtitle file can be inserted into the video file In the case of data, the file data (image file) is converted to include a subtitle file in the file data to generate a modified file (hereinafter referred to as a bundle file).

The method for generating the bundled file will be described in detail below with reference to the operation of the present invention.

FIG. 4 is a flowchart illustrating a method of supporting a terminal support system according to a specific embodiment of the present invention (moving picture file transmission method).

First, the support control module, which receives the transmission command of the data file from the user to the terminal 200, determines whether or not a caption file exists in the transmission commanded data file (S110, S120). Here, it is assumed that the present invention is applied to a moving picture file, and that the data file to be transmitted is a moving picture file. In addition, the caption file is included in the data file, including the case where a caption file having a file name such as a moving picture file to be transmitted exists in the same folder.

This is because there is no caption when the data file is a domestic moving picture file, and it is not necessary to go through each step of the present invention. If it is determined in operation 120 that the subtitle file does not exist, the data file is directly transmitted in operation S150.

Next, when the subtitle file is included in the data file, it is determined whether subtitle information exists on the feature table stored in the connected terminal 200 (S130). This is because the subtitle information has priority over the display information described below as a reference for format change of the subtitle data.

If the caption information exists, the support control module 110 converts the caption file format to correspond to the caption information (S134). That is, the caption size, color, and font of the caption file are reset.

If there is no caption information on the feature table, the format of the caption file is converted so as to correspond to the display information (S136). That is, the size, color, and font settings of the subtitle file are reset to be appropriate to the resolution and size of the display. The appropriate value may preferably be stored and changed by the user or program designer.

If the format of the caption file is changed, it is determined whether the terminal 200 connected next supports the caption file (S140). The terminal not supporting the caption file refers to a terminal that does not have a function of storing another caption file and synchronizing the caption file with the video file when the corresponding video file is played back. In order to listen to a moving picture including a caption in such a terminal, the caption must be added to the moving picture file to form one moving picture file.

If it is determined in operation 140 that the terminal 200 does not support the caption file, the caption file is combined with the caption file to generate a combined file (S146). Then, the composite file integrated with the caption is transmitted (S150).

If it is determined in operation 140 that the connected terminal 200 supports the subtitle file, it is determined whether the type of the moving picture file to be transmitted is a subtitle-insertable file (S142).

This is because the support control module 110 inserts a caption file in a header or a tail portion of the video file before transmitting the video file, It is to determine whether it is type.

Of course, the format of the representative video file will support the conversion of the support control module, but it can not support all of the non-representative formats of video files, so the above steps are performed.

Thereafter, if the moving picture file is a moving picture file of a subtitle-insertable format, a subtitle file is added to the moving picture file to generate a bundled file (S150).

A method of generating the transformed file will be described in detail with reference to FIGS. 5A and 5B.

After the bundle file is generated, the converted file is transmitted to the terminal 200 (S150).

Hereinafter, a method of generating the change file by the support control module will be described.

FIG. 5A shows a structure of a transmission file according to a specific embodiment of the present invention, and FIG. 5B shows a file header portion of a RIFF structure according to a specific embodiment of the present invention.

As shown in the drawing, the data structure of the moving picture file includes a packet in which actual data is stored and a header and a tail respectively attached to the front and rear ends of the packet.

The support control module 110 generates a bundle file by including caption data in the header or tail portion.

At this time, the structure of the header or the tail is slightly different depending on the type of each moving picture file. Therefore, the support control module 110 needs to know the structure of the header or tail to insert the caption data according to a typical video file type.

At this time, the support control module 110 determines that the subtitle can not be inserted into the moving picture file having the header or tail structure that the support control module 110 can not grasp.

FIG. 5B is a diagram showing a position of insertion of caption data in a header in an AVI format file of a moving image file.

In the header of the AVI file as shown, a bundle file is created by inserting a subtitle file in the part of "LIST ('info'".

Hereinafter, a method for the terminal 200 receiving the moving image file to play the received moving image file will be described.

FIG. 6 is a flowchart illustrating a method of reproducing a moving picture file according to a specific embodiment of the present invention.

As shown in the figure, the terminal 200 according to the present invention stores the moving picture file received from the terminal 200 supporting system in the storage unit 230 (S210). At this time, if the caption file is received together, the received caption file is also stored together with the video file.

If there is a reproduction command for the moving picture file, it is determined whether the moving picture file is a converted file in which the caption is inserted (S220). The determination is made by examining a header or a tail portion of the moving image file.

At this time, in the case of the moving picture file, the subtitle data inserted in the header or tail of the moving picture file is extracted and stored in the buffer (S230, S232). Of course, it is also possible to extract all the caption data and generate one caption file.

Subsequently, the moving picture file and the caption data are played back together. At this time, the caption data is synchronized with the moving picture file and played back (S234).

If it is determined in operation 220 that the moving picture file is not a transformed file, it is determined whether a subtitle file matching the moving picture file exists in the storage unit 230 in operation S240.

If the subtitle file exists, the subtitle file and the moving image file are played together (S234).

However, if the subtitle file does not exist, it means that the moving picture file is a moving picture file without original subtitles or a moving picture file (composite file, see step 146) generated by combining subtitles in the moving picture file, (S242).

Hereinafter, it will be seen how the present invention works within the overall single device support method of the terminal support system.

FIG. 7 is a flowchart illustrating an overall procedure of a terminal support method of a terminal support system including a specific embodiment of the present invention.

The support control module 110 waits while monitoring the peripheral control module 160 periodically until the terminal 200 having the playback function is connected to the peripheral control module 160 in operation S310. When it is detected that the terminal 200 is connected to the peripheral control module 160, the support control module 110 controls the peripheral control module 160 to transmit the feature The table is read (operation S312). In addition, the support control module 110 supplies support menu information to the display device (not shown) via the video controller 120 so that the support menu is displayed on the display device (step S314). When the support menu is displayed on the display device, the user can select any of the support menus. The support menu includes a table update mode, a firmware update mode, an online registration mode, a file downloading mode, and an online downloading mode. After displaying the support menu, the support control module 110 receives a table update mode, a firmware update mode, an online registration mode, a file downloading mode, and an online downloading mode from an input device (not shown) connected to the input controller 150 And waits until a command for designating any one is inputted (steps S316 to S324).

When the instruction for designating the table update mode is inputted from the input controller 150 in step S316, the support control module 110 supplies information on the updatable items to the display device via the video controller 120, So that the items are displayed on the display device (Step S326). The support control module 110 scans the input device connected to the input controller 150 to check whether the update information that the user wants to update is inputted (step S328). If the update information is input in step S328, the support control module 110 loads the update information of the inputted user into the terminal 200 connected to the peripheral control module 160 and stores the corresponding item on the feature table in the terminal 200 To be updated with the input information of the user (operation S330). At this time, items on the feature table in the terminal 200 that can be updated are a user name, a user access number, and a user password included in the user information. The updating of the feature table by the user can prevent the use of the terminal 200 by another person. In addition, the initial language and frequency modulation information among the items on the feature table in the terminal 200 can also be updated. The initial language may be reset by the user or supplier according to the country in which the terminal 200 is to be used and the frequency modulation information may likewise be reset by the user or supplier according to the country or environment in which the terminal 200 is to be used .

If the firmware update mode designation command is input from the input controller 150 in step S318, the support control module 110 searches the read feature table for the manufacturer name and model name of the terminal 200 (step S332). And accesses the online site of the manufacturer of the terminal 200 through the communication network connected to the communication module 170 using the name of the manufacturer of the searched terminal 200 (step S334). In addition, the support control module 110 downloads the firmware corresponding to the model name retrieved from the online site of the manufacturer (Step S336). At this time, the downloaded firmware is temporarily stored in the main memory 130. Then, the support control module 110 downloads the downloaded firmware to the terminal 200 connected to the peripheral controller 160 to update the firmware in the terminal 200 (step S338). Updating the firmware in the terminal 200 can facilitate maintenance of the terminal 200, easily add a new function to the terminal 200, or reinforce unstable functions.

If the instruction for designating the on-line registration mode is input from the input controller 150 in step S320, the support control module 110 searches the title table and the serial number of the terminal 200 on the read feature table (step S340) . And accesses the online site of the manufacturer of the terminal 200 through the communication network connected to the communication module 170 using the name of the manufacturer of the searched terminal 200 (step S342). In addition, the support control module 110 transmits the searched serial number to the online site of the manufacturer of the terminal 200 so that the serial number of the terminal 200 is registered in the online site of the manufacturer (Step S344). Then, the support control module 110 scans an input device connected to the input controller 150 to check whether information related to the user (i.e., user information) is input (step S346). If the user information is input in step S346, the support control module 110 transmits the inputted user information to the online site of the manufacturer of the terminal 200 through the communication module 170 and the communication network, (Step S348). The user information includes a user name, a user address, and a telephone number of the terminal 200. Registration of such user information enables tracking of the lost or stolen terminal 200, thereby preventing loss and theft. In addition, the registration of user information enables tracking of the illegal distribution of the terminal 200, such as the sale of stolen goods accompanied by the removal of the serial number label and the dumping sale of wholesalers. Further, after the online registration of the user information, the support control module 110 may download the coupon from the manufacturer's online site via the communication network and the communication module 170. [ The coupon thus downloaded may be stored in the terminal 200 again via the peripheral control module 160 by the support control module 110. Such downloading of the coupon can prevent unauthorized use of the coupon by forgery or alteration of the coupon in the form of a sheet, and can prevent a case in which the coupon is not benefited from the loss of the coupon in the form of a sheet.

In step S322, when the designation command of the file downloading mode is input, the support control module 110 generates data on the image and / or sound information stored in the hard disk 140 based on the DRM information on the read feature table And retrieves data files that can be reproduced from the terminal 200 among the files. In addition, the support control module 110 creates the retrieved data files in the form of a list, and supplies the created data file list to the display device via the video controller 120 to display the reproducible data file list (S350 step). Then, the support control module 110 scans the input device connected to the input controller 150 to check whether there is a designation of data files to be downloaded from the data file list (step S352). If there is a designation of the data files to be downloaded in step S352, the support control module 110 optimizes the designated data files to read from the hard disk 140 and appropriately to be reproduced by the terminal 200 (Step S354).

At this time, in the optimization of operation 354, when the data file is a moving image file, the method described in FIG. 4 is applied.

Then, the support control module 110 causes the optimized data files to be downloaded to the terminal 200 via the peripheral control module 160 (step S356). In this way, only the data files of the DRM means which can be released from among the data files of the video and / or audio information stored in advance in the hard disk 140 can be selected and the user can easily download the reproducible data file to the terminal 200 .

In step S324, the support control module 110 searches for the DRM information in the read feature table if the instruction for specifying the online download mode is input (operation S358). Based on the retrieved DRM information, the support control module 110 creates a list of content servers compatible with the terminal 200 (operation S360). In step S362, the support control module 110 scans the input device connected to the input controller 150 to determine whether there is a content server to be accessed among the content servers in the compatible content server list. If there is a designation of a content server to be accessed in step S362, the support control module 110 connects with the content server selected via the communication module 170 and the communication network, and transmits the video and / A list of data files for information is displayed on the display device via the video controller 120 (Step S364). At this time, the user can select the data files in the data file list provided by the compatible content server. After step S364, the support control module 110 scans an input device connected to the input controller 150 to check whether there is a designation of data files to be downloaded from the data file list of the content server (step S356). If there is a designation of data files to be downloaded in step S352, the support control module 110 may request optimization of the specified data files to the connected content server (step S368). If there is an optimization request for this data file, the content server optimizes the requested data files and allows the optimized data files to be transmitted over the communication network to the communication module 170 of the support system. Here, the optimization process of the data file is as described in FIG.

Then, the support control module 110 downloads the optimized data file from the content server connected via the communication network and the communication module 170 (step S370). If the optimization request for the selected data files is not made, the support control module 110 downloads the data files designated by the user from the connected content server in an unoptimized state. Then, the support control module 110 causes the downloaded data files from the downloaded content server to be downloaded again to the terminal 200 via the peripheral control module 160 (step S372). Thus, by guiding the selection of the content servers compatible with the terminal 200, the support control module 110 enables only the data files that can be reproduced from the terminal 200 to be downloaded online. Further, the user can easily download desired data files online.

The program implementing the support method for the terminal as described above may be stored in the terminal instead of being stored in the hard disk 140 of the support system shown in FIG. In this case, the support system for the terminal may be replaced with a normal personal computer. When the terminal is connected to the support system (that is, the personal computer), the program of the downloading method stored in the portable playback apparatus 200 is downloaded to the hard disk 140 of the support system (i.e., the personal computer) Loaded into the memory 130 and performed by the support control module 110.
