The communication program 110b defines a communication protocol in order to communicate with the personal information processor 400 and the content providing system 300, and controls a universal asynchronous receiver / transmitter (UART) of a computer. In addition, the communication program 110b manages an input / output buffer for transmitting and receiving data, sets a port, and defines a data structure to perform a communication emulator function.

The data processing program 110a is an application program layer that performs a sink function and provides an interface with a user.

FIG. 2 schematically shows the configuration of the data processing program 110a among the sink programs installed in the computer 100 according to the present invention to realize the function of auto-synchronizing the content file of the Internet site with the personal information processor 400. As shown in FIG. It is a block diagram.

Referring to Fig. 2, the auto sync program 110 (hereinafter, the auto sync program means the data processing program 110a) according to the present invention is a user registration module 111 which provides a user interface, and an automatic login. The module 112 and the file editing module 113, the terminal recognition module 114 performing the sync function, the encoding module 115 and the data synchronization module 116, and the media playback module 117 providing additional functions. ) And P2P (Peer to Peer) module.

The user registration module 111 may include user information (eg, personal information including a name), memory information (eg, 64M) of the personal information processor 400, a terminal authentication number (eg, describe a unique serial number of the terminal), and Receive an authentication number for the automatic connection with the content providing system 300 from the user. Here, the authentication number for the automatic connection with the content providing system 300 is, for example, the same as the ID and password registered by the user accessing the Internet to the above-described content providing system 300, the automatic login module (to be described later) Input to the auto-sync program 110 through the login screen provided by 112.

Receiving the authentication number of the terminal is to distinguish the content files so as to enable synchronization of each content file, when the user uses a plurality of personal information processor 400 as the same model.

3 is a login screen provided after the computer 100 is booted by the auto-login module 112 according to the present invention and the auto-login module 112 is executed after the login process is executed. The screen on the window exemplarily shows that the program 110 is waiting for a tray icon.

The automatic login module 112 logs in when the computer 100 is booted and the operating system 130 (eg, Windows 2000) starts to operate while the auto-sink program 110 according to the present invention is installed in the computer 100. The screen 10 is provided to receive an authentication number for accessing the content providing system 300 from the user as described above.

When the automatic login module 112 is authenticated, the automatic login module 112 may execute the sink function in cooperation with the content providing system 300 in earnest. That is, the automatic login module 112 is connected to the content providing system 300 (the minimum signal is sent out periodically so as not to be disconnected) and the tray icon 30 is executed to make the user registration module 111, The terminal recognition module 114, the data synchronization module 116, the file editing module 113 and the encoding module 115 to wait.

According to the example screen shown in FIG. 3, when the authentication process is completed, the login screen 10 is processed and disappears, and a tray icon 30 that newly displays the running auto sync program is newly created in the tray icon area 20. .

The file editing module 113 provides an edit window for selecting a sync mode, an edit window for selecting existing content to be resident in memory, and an edit window for selecting a time priority of the content file to be synced. This can prevent problems (e.g. excess memory problems, deleting existing stored files, etc.).

That is, the user may first access the above-described content providing system 300 and select the content files that the user wants to auto-sync (for example, by clicking on "Preview", the contents may be checked and the contents may be posted according to the sequence). From the file names, click on the file name you want to auto-sync, and put it in the personal channel assigned to the user (meaning a storage space). Second, the user can select the content files through the edit window to select the time priority of the content file to be synchronized provided by the file editing module 113 among the auto-sink program 110 according to the present invention (hereinafter, In order to distinguish it from 'auto sync', it will be referred to as 'edit sync'), which will be described later.

Subsequently, program elements that perform a sink function will be described.

The terminal recognition module 114 recognizes when the personal information processor 400 is mounted on the cradle 500, receives the authentication number from the personal information processor 400, and transmits the authentication number to the content providing system 300.

The personal information processor 400 stores a communication program (not shown) that enables communication with the autosync program 110 according to the present invention in a memory. The device transmits a recognition request signal and transmits serial number data unique to a device embedded in the terminal recognition module 114 according to a request of the terminal recognition module 114.

The data synchronization module 116 receives the content file and file editing information from the content providing system 300 (in the case of the auto sync, the auto sync program 110 does not store the received data in the computer 100 and transmits the data). The stored data is stored in the database server 310 of the content providing system 300 as described above), the content file and the file information stored from the personal information processor 400 are received and compared, and the personal information processor 400 is compared. Syncs the content file data transmitted from the content providing system 300 to the memory of FIG.

The encoding module 115 resizes the content provided by the content providing system 300 to fit the display specification of the personal information processor 400 and codes the data into a predetermined format.

The personal information processor according to the related art relies on a text-based display device for providing Internet contents. However, the personal information processor 400 connected to the autosync program 110 according to the present invention is a memory (screen) DC ( Device Content), an image processing apparatus, and a display apparatus capable of displaying moving image color data.

The encoding module 115 resizes the screen size at the time of displaying the video content file to match the screen size of the personal information processor 400. For example, a content file size of a general Internet broadcasting station may be 3.20 mm × 2.40 mm or 1.76 mm × 1.44 mm so that a normal display is possible even in a specific personal information processor 400. The resizing of the screen can be realized by comparing duplicate data in four adjacent directions among the data constituting the screen.

The encoding module 115 codes the various data formats into the specified specific format. In the case of moving picture data, the autosync program 110 according to the present invention assumes that the specific format is converted to MPEG4.

Data formats (including both video and audio) that can be processed by the encoding module 115 are supported by Window Media Audio File (WMA) and Audio Video Interleaved (AVI) (Microsoft Video for Windows). Type name of the compressed video file), AAC (Advance Audio Coding Standard; part of MPEG2 audio), MP3 (MPEG-1 Layer3; technology adopted as a standard for high-quality audio compression by the International Organization for Standardization), and ASF (MS). Advanced Streaming Format File, etc., and resizing is performed at 15 frames per second and has a bandwidth of 128 Kbps (bit per second). Therefore, the encoding module 115 has a codec program.

The autosync program 110 according to the present invention described above may further include a media play module 117 and a P2P module 118 for executing additional functions.

The media playback module 117 stores the content file transmitted from the content providing system 300 in the computer 100, and reproduces and displays the stored content file or the content file streamed from the content providing system 300. The media playback module 117 may provide a media playback user interface to perform a reservation function, a caption function, an editing function, a file management function, and the like.

The P2P module 118 stores the content file transmitted from the content providing system 300 on the computer 100 and shares the content file with another computer connected using P2P technology.

The peer-to-peer model refers to how one peer performs both server and client roles. Therefore, P2P is a network technology that can greatly reduce the load because all peers are symmetric and each peer divides the work of the server.

The P2P module 118 is added to a network capable of sharing various media files (hereinafter referred to as a "shared network") using another computer having the autosync program 110 according to the present invention as one node. can do. Each computer stores a list of nodes through an Internet Protocol (IP) address cache.

The connection of the shared network through the connection of nodes is performed by the P2P module 118 of the computer 100 sending and receiving a ping message and a Pong message, respectively (by using a broadcasting). The ping message sent by the P2P module 118 solves the repeatability problem of the node by using the time to live (TTL) value and the global unique identifier (GUID) and increases the nodes in the shared network. Pong messages, on the other hand, contain information about the number and capacity of files owned, in addition to information needed to communicate, such as their IP address and port. The P2P module 118 of each node can send a query message on the shared network to find the file it wants.

The P2P module 118 that finds the file transmits a request message to the P2P module 118 of the partner's computer, and the partner's P2P module 118 sends the same message to synchronize (sync) and then transfers the file. .

Hereinafter, referring to FIG. 4, an autosync is connected to the computer 100 that is connected to the content providing system 300 through the Internet 200 according to the present invention and connected to the personal information processor 400 through a USB port. A method of synchronizing the content file with the personal information processor 400 by operating the program 110 will be described in detail.

First, when the computer 100 is booted, the automatic login module 112 provides a login screen. When the login information is input by the user, the automatic login module 112 executes a tray icon and receives the sink mode (S100). There are two sync modes: auto sync and edit sync.

The auto sync program 110, which has selected the auto sync mode from the user, waits for a predetermined time and receives an authentication number when it recognizes that the personal information processor 400 is mounted in the cradle (S200). The auto-sync program 110 which maintains the minimum connection with the content providing system 300 through the Internet 200 activates the connection and transmits the received authentication number to the content providing system 300 (S300).

After providing and authenticating the personal information processor 400 through the authentication number, the content providing system 300 transmits content files set by the user (files stored in the DB server 310 as described above). do. The data synchronization module 116 receives the content file and the file editing information from the content providing system 300 and receives the stored content file and the file information from the personal information processor 400 to compare and exchange them (S400).

At this time, if the result of the synchronization is not necessary (S500), the data synchronization module 116 terminates the sync procedure, and if synchronization is necessary (S500), the data synchronization module 116 checks the set autosync mode (S600). The priority of each content file and the transferable file are determined (S700). In determining the transferable file, the memory capacity will be the most important parameter in determining the transferable file.

In this case, when the set mode is the edit sink mode (S600), the data synchronization module 116 receives a request for selecting a content file to be stored even after the update through the sink, which is stored in the memory of the personal information processor (S600). S1200) The data editing module provides an edit window to receive the content file (S1300), and then selects the content files to be synced by providing an edit window for the edit sink mode (S1400).

The content files selected to remain in the memory of the personal information processor are processed so as not to be deleted from the memory of the personal information processor even though the sink (regardless of whether they are auto sync or edit sync) is performed (S1300).

If there is no request for selecting a content file to remain in the memory of the personal information processor, the data editing module provides an edit window and receives the content files to be synchronized immediately. The edit window provided here is provided as a separate window for each editing function.

In the edit mode, when the files are selected, the data synchronization module 116 determines the time priority and the transferable file of the selected content file (S700).

Meanwhile, the data synchronization module 116 performs the above-described determination function (S700) and then determines whether the memory is exceeded (S800) (corresponding to both modes). At this time, if the memory excess is detected, the file editing module 113 provides a file editing window as described above (it is repeated in the case of the editing mode) to receive a selectable file within the memory acceptance limit.

Finally, in the auto-sync mode (S900), the data synchronization module 116 deletes all content files stored in the memory of the personal information processor 400 (S1000) (recurring information, that is, the header file of the information and the like). Likewise, the data can be synced by indicating the same contents, but as the number of times the data file is changed differently, only the header file is synced and the rest of the data files are deleted, and the selected information is downloaded according to the sync result. This method is advantageous, and when the MPEG video file is synced, this method is used). The sync process is terminated by downloading the content files (S1100). However, in the edit mode, the sync process is terminated by directly downloading the edited files to the personal information processor 400 to enable transmission without the memory initialization process S900 described above (S1100).

If the content file does not conform to the display specification of the personal information processor in the process of downloading the files to the personal information processor 400 by the data synchronization module 116, the encoding module 115 may be configured as the data synchronization module 116. ) Resizing and downloading the content file received from the content providing system to be displayed in the personal information processor.

In other words, when a user accesses a content providing system and selects a content, if the cradle is equipped with a personal information processor, the cradle is automatically synchronized to the personal information processor without being stored in the above-described database server. If not mounted, the selected content files are stored in the database server of the content providing system.

The present invention has been described above with reference to the preferred embodiments, which are merely examples and are not intended to limit the present invention, and those skilled in the art to which the present invention pertains do not depart from the essential characteristics of the present invention. It will be appreciated that various modifications and applications are not possible that are not illustrated above. For example, each component specifically shown in the embodiment of the present invention can be modified. And differences relating to such modifications and applications will have to be construed as being included in the scope of the invention defined in the appended claims.

As described above, according to the sync program recorded on the recording medium according to the present invention to realize the function of auto-synchronizing the content data of the Internet site with the personal information processor, the cradle is provided via the Internet only by mounting the personal information processor. Various media data including video data can be auto-synced.

In addition, according to the present invention, by providing a user interface for editing the content material to be synchronized in various stages, it is possible to provide a convenient auto-sink method with a low transmission failure rate.

In addition, according to the present invention, by incorporating a P2P program into an autosync program, it is possible to autosync video data stored in another user computer as well as the Internet.
