The present invention relates to a system and method for supporting a portable device.

Conventional portable devices allow a user to send and receive information, listen to and / or view information while on the move. Portable devices have evolved from single functions such as mobile phones, portable players and portable receivers to portable multimedia forms with added playback capabilities. Such portable devices have recently introduced software blocks instead of a significant portion of hardware blocks to implement signal processing and control. This is due to the fact that it is easy to add additional functions and change the signal processing and control logic according to the use environment.

As described above, in a portable device including circuit blocks implemented by software, failures and breakdowns inevitably occur. In addition, for portable devices, the reinforcement of functions and / or the addition of functions are frequently performed by manufacturers. Whenever this maintenance and function update was needed, the user of the portable device had to visit the after-sales service center of the portable device.

On the other hand, a portable device having a playback function enables listening or viewing of sound and / or video information while moving. The portable device having such a reproduction function has been replaced with a recording medium-embedded form in the form of replacing the recording medium in that small size and light weight can be reduced. The portable device having a built-in recording medium allows a data file of necessary sound and / or image information to be downloaded to a recording medium (for example, a hard disk or a nonvolatile memory) in itself, and reproduces the data file stored in the recording medium. Such recording media embedded portable devices are being developed to store more data files due to the development of integrated circuit technology.

The data file to be downloaded to the portable device of the playback function includes digital rights management (DRM) means (or function) for protecting the copyright of the provider (or creator of the audio and video information). Is being added. The DRM means are implemented by the program so that the data files are not reproduced by unauthorized individuals or organizations. In addition, the DRM means are implemented in a unique form according to the creator of the data file.

As the DRM means is added to the data file, the portable device of the reproduction function can play the data file only after releasing the DRM means. In order to release the DRM means, the portable device of the reproduction function includes the DRM release function. The DRM release function is implemented by the program. In addition, the DRM release function can be provided in the portable device of the playback function by supplying the data file provider (i.e. the producer or creator) to the producer of the portable device of the playback function.

As such, since the DRM release means must be provided to the producer of the portable device by the provider of the data file, the portable device can reproduce only the data files of the DRM means corresponding to the DRM release means in itself. In other words, the current portable device cannot reproduce all of the data files from all the suppliers due to the DRM means, but can only play the data files from some of the suppliers. As a result, it was not only difficult to download data files playable by the portable device, but also had to consume a lot of time.

In view of these aspects, there is a need for a method for facilitating maintenance of a portable device, updating of functions, and downloading of data files.

1 is a block diagram schematically illustrating a support system for a portable device according to an exemplary embodiment of the present invention. The support system for the portable device of FIG. 1 includes a video controller 20, a main memory 30, a hard disk 40, an input controller 50, a peripheral control module 60 and communication connected to the support control module 10. Module 70 is provided. The support control module 10 supports the portable device 100 connected to the peripheral control module 50. In detail, the support control module 10 is capable of downloading the update program to the portable device for maintenance and function update of the portable device and reproducing the portable device for viewing or listening to video and / or sound information. Download data files, etc. In addition, the support control module 10 performs a download of a program for registering and updating user information and a reproducible data file through the communication module 70. The support operation of the support control module 10 will be described in detail with reference to the flowchart shown in FIG. 3. In addition to the support operation, the support control module 10 may control the video controller 20, the main memory 30, the hard disk 40, the input controller 50, the peripheral control module 60, and the communication module 70. Perform data operations and logic operations. For this purpose, the support control module 10 includes a North Bridge 14 and a South Bridge 16 connected in series with a Central Process Unit (hereinafter referred to as "CPU") 12. ).

The CPU 12 downloads an update program to the portable device for maintenance and function update of the portable device 100 and downloads a playable data file to the portable device for viewing or listening to video and / or sound information. Loading and so on. In addition, the CPU 12 downloads a program for registering and updating user information and a reproducible data file through the communication module 70. In addition, the CPU 12 includes the north bridge 14, the south bridge 16, the video controller 20, the main memory 30, the hard disk 40, the input controller 50, and the peripheral control module 60. And control, data operation, and logic operation of the communication module 70. To this end, the CPU 12 includes an arithmetic logic unit (ALU), a control unit, a register and a storage device interface.

The north bridge 14 relays bidirectional data communication with the CPU 12 and each of the video controller 20 and the main memory 30, which are peripherals that operate relatively fast, including the south bridge 16. In addition, under the control of the CPU 12, the north bridge 14 controls the video controller 20, the main memory 30, and the south bridge 16.

South Bridge 16 is a type of register collection that manages the input and output of each of the relatively slow peripherals. This south bridge 16 is bidirectional data between the hard disk 40, the input controller 50, the peripheral control module 60 and the communication module 70, and the CPU 12 connected via the north bridge 14, respectively. Relay the transmission. In addition, the south bridge 16, under the control of the connected CPU 12 via the north bridge 14, the hard disk driver 40, input controller 50, peripheral control module 60 and communication module Control 70. For this purpose, the south bridge 16 is connected to the north bridge 14 by a PCI bus (not shown).

The video controller 20 causes the data processed by the support control module 10 (ie, the CPU 12) to be displayed on a display device, such as a cathode ray tube or liquid crystal display panel. To this end, the video controller 20 may be connected to the north bridge 14 by an accelerated graphic port (AGP).

The main memory 30 provides a workspace for the support control module 10, specifically the CPU 12. In other words, the main memory 30 temporarily stores data processed or to be processed by the CPU 12 in the support control module 10. For this purpose, the main memory 30 is connected to the north bridge 14.

The hard disk 40 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 ROM. The operating system stored in the hard disk 40 is uploaded to the main memory 30 by a system booting operation and executed. Various application programs stored in the hard disk 40 are also uploaded and executed in the main memory 30 at the user's choice.

The input controller 50 transmits data input through an input device such as a keyboard and a mouse to the CPU 12 via the south bridge 16 and the north bridge 14.

The peripheral control module 60 controls data input / output between the support system and the portable device. In other words, the peripheral control module 60 relays bidirectional data transmission between the support control module 10 (specifically, the CPU 12) and the portable device 100 to be supported. To this end, the peripheral control module 60 is connected to the portable device 100 to be supported by a universal serial bus (USB).

The communication module 70 relays bidirectional communication between the support system and the communication network. Specifically, the communication module 70 transmits data from the public telephone network or the local area network to the support control module 10 (ie, the CPU 12 via the south bridge 16 and the north bridge 14). Or send data from the support control module 10 (i.e., transmitted from the CPU 12 via the north bridge 14 and the south bridge 16) to a public telephone network or a local area network. To this end, the communication module 70 is connected to the south bridge 16 by PCI or USB.

The portable apparatus 100 connected to the peripheral control module 60 may be a portable telephone, a portable receiver portable player, or a portable telephone or portable receiver having a playback function. For convenience of explanation, the peripheral control module 60 is connected to a portable device such as a mobile telephone having a playback function. The portable device stores a feature table as shown in FIG.

Referring to FIG. 2, 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. User information includes a user name, user access number, and user password. This user information is recorded by the user. The DRM information includes data on the DRM means that can be released among various DRM means depending on the producer of the data file for the image and / or sound 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, type of recording medium, and battery support information may be included.

In addition, the feature table stores display information and subtitle information as shown in FIG. 2. The display information and the caption information are data for optimizing the caption file in a portable device, and the display information includes the type, resolution, and size information of the display. The caption information stores supportable file format information, which is a format of a caption file supported by a portable device, and caption size, caption color, and font information.

Accordingly, when the subtitle file is transmitted to the portable device, the support control module 10 first searches for the subtitle information and changes the format of the subtitle file into a format stored in the subtitle information. In this case, if the format of the subtitle file is not supported by the portable terminal, it may be converted into a format supported by the portable apparatus 100.

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

On the other hand, the support control module 10 checks whether the connected portable device 100 is a portable device that supports a subtitle file, and does not support a subtitle file (for example, an MP3 or the like does not generally support a device). If not, the converted subtitle file is combined with the video file and transmitted. In this case, the subtitle file is preferably pasted into the video file using a filter.

3 is a flowchart illustrating a method for supporting a portable device according to an embodiment of the present invention step by step. 3 is a program stored in the hard disk 40 included in the support system of FIG. 1, which is performed by the support control module 10 (in detail, the CPU 12). To this end, the flowchart of FIG. 3 is uploaded from the hard disk 40 to the main memory 30 upon startup of the support system. The process in which the flowchart of FIG. 3 is performed by the support control module 10 will be described in detail in connection with the support system of FIG. 1.

The support control module 10 periodically waits while monitoring the peripheral control module 60 until the portable device 100 having the regeneration function is connected to the peripheral control module 60 (step S10). When it is detected that the portable device 100 is connected to the peripheral control module 60, the support control module 10 is stored in the portable device 100 via the peripheral control module 60 as shown in FIG. 2. The same feature table is read (step S12). In addition, the support control module 10 supplies the support menu information to the display device (not shown) via the video controller 20 so that the support menu is displayed on the display device (step S14). When the support menu is displayed on the display device, the user can select one of the support menus. The support menu includes table update mode, firmware update mode, online registration mode, file downloading mode and online downloading mode. After the display of the support menu, the support control module 10 performs 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 50. It waits until a command specifying which one is input (steps S16 to S24).

When the designation command of the table update mode is input from the input controller 50 in step S16, the support control module 10 may supply information on the updatable items to the display device via the video controller 20 to enable updating. The items are displayed on the display device (step S26). The support control module 10 scans an input device connected to the input controller 50 and checks whether update information to be updated by the user is input (step S28). If the update information is input in step S28, the support control module 10 loads the input update information of the user to the portable device 100 connected to the peripheral control module 60 to display on the feature table in the portable device 100. The information of the corresponding item is updated with the user's input information (step S30). At this time, the items on the feature table in the portable device 100 that can be updated are the user name, the user access number, and the user password included in the user information. Such updating of the feature table by the user can prevent the use of the portable device by others. In addition, initial language and frequency modulation information may be updated among items on the feature table in the portable apparatus 100. The initial language may be reset by the user or distributor as appropriate for the country in which the portable device will be used, and the frequency modulation information may likewise be reset by the user or distributor depending on the country or environment in which the portable device will be used.

When the command for specifying the firmware update mode is input from the input controller 50 in step S18, the support control module 10 searches for the manufacturer name and model name of the portable apparatus 100 in the read feature table (step S32). . The searched manufacturer's name of the portable apparatus 100 is used to connect to the online site of the manufacturer of the portable apparatus 100 via a communication network connected to the communication module 70 (step S34). In addition, the support control module 10 downloads the firmware corresponding to the model name retrieved from the online site of the manufacturer (step S36). At this time, the downloaded firmware is temporarily stored in the main memory 30. Subsequently, the support control module 10 downloads the downloaded firmware back to the portable apparatus 100 connected to the peripheral controller 60 so that the firmware in the portable apparatus 100 is updated (step S38). By updating the firmware in the portable device 100, maintenance of the portable device 100 may be facilitated, new functions may be easily added to the portable device 100, or an unstable function may be easily reinforced.

When the designation command of the online registration mode is input from the input controller 50 in step S20, the support control module 10 searches for the manufacturer name and serial number of the portable device 100 in the read feature table (step S40). ). The searched manufacturer's name of the portable apparatus 100 is used to connect to the online site of the manufacturer of the portable apparatus 100 via a communication network connected to the communication module 70 (step S42). In addition, the support control module 10 transmits the retrieved serial number to the online site of the manufacturer of the portable device 100 so that the serial number of the portable device 100 is registered at the online site of the manufacturer (step S44). Subsequently, the support control module 10 scans an input device connected to the input controller 50 and checks whether information related to the user (that is, user information) is input (step S46). When the user information is input in step S46, the support control module 10 transmits the input user information to the online site of the manufacturer of the mobile device 100 through the communication module 70 and the communication network so that the user information is sent online by the manufacturer. Registration on the site (step S48). The user information includes a user name, a user address and a phone number of the portable device 100. Registration of such user information enables tracking of lost or stolen portable devices, thereby preventing loss and theft. In addition, registration of the user information enables tracking of illegal portable device distributors, such as the sale of stolen products and the dumping sale of wholesalers with the removal of serial number labels. Furthermore, after the online registration of the user information, the support control module 10 may download the coupon from the manufacturer's online site via the communication network and the communication module 70 (step S48-1). The downloaded coupon may be stored in the portable device 100 by the support control module 10 via the peripheral control module 60. Downloading such a coupon can prevent illegal use by counterfeiting or tampering with the coupon in the form of a sheet, and can also prevent a case in which the coupon is not benefited from the loss of the coupon in the form of a sheet.

When a command for specifying a file downloading mode is input in step S22, the support control module 10 may transmit data regarding video and / or sound information stored in the hard disk 40 based on the read DRM information on the feature table. Search for data files that can be played on the portable device 100 among the files. In addition, the support control module 10 prepares 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 20 so that the list of playable data files is displayed (S50). step). Subsequently, the support control module 10 scans an input device connected to the input controller 50 to check whether there is a designation of data files to be downloaded from the list of data files (step S52). If there is a designation of data files to be downloaded in step S52, the support control module 10 optimizes the designated data files to be read from the hard disk 40 so that the read data files are suitable for being reproduced by the portable device 100. (Step S54).

In this case, when the data file to be optimized is a video file, the optimization process of the video file (including the subtitle file) will be described with reference to FIG. 4.

As shown in FIG. 4, it is first checked whether a data file to be optimized is a video file (S54-1). If the data file to be optimized is a video file, it is determined whether subtitle information exists on a feature table (S54-2). This is because the caption information has priority over display information to be described later as a criterion for changing the format of the caption data.

If the caption information exists, the support control module 10 converts the format of the caption file to correspond to the caption information (S54-3). That is, the subtitle file size, color, font is reset.

On the other hand, if there is no caption information on the feature table, the format of the caption file is converted to correspond to the display information (S54-4). That is, the size, color and font settings of the subtitle file are reset to be appropriate for the resolution and size of the display. Preferably, the appropriate value can be stored and changed by the user or program designer.

If the format of the subtitle file is changed, it is then determined whether the connected portable device 100 supports the subtitle file (S54-5). Here, a model that does not support the subtitle file refers to a portable device that does not have a function of storing a separate subtitle file and synchronizing the subtitle file with the video file when a corresponding video file is played. In order to view a video including subtitles in such a portable device, the video file is subjected to the caption to produce a single video file.

Therefore, if the portable device does not support the caption file as a result of the determination in step 54-5, the caption file is combined with the video file (S54-6). Then, the video file integrated with the subtitle is compressed (S54-7).

Thereafter, the support control module 10 causes the optimized data files to be downloaded to the portable device 100 via the peripheral control module 60 (step S56). In this way, only data files of the releaseable DRM means can be selected among the data files for the image and / or sound information pre-stored in the hard disk 40 so that the user can easily reproduce the playable data file to the portable device 100. Make it available for download.

When the instruction for designating the online downloading mode is input in step S24, the support control module 10 searches for the DRM information in the read feature table (step S58). Based on the retrieved DRM information, the support control module 10 creates a list of content servers compatible with the portable apparatus 100 (step S60). In addition, the support control module 10 scans an input device connected to the input controller 50 to check whether there is a designation of a content server to be accessed among the content servers in the compatible content server list (step S62). If there is a designation of the content server to be accessed in step S62, the support control module 10 connects to the selected content server via the communication module 70 and the communication network, and the video and / or sound provided by the connected content server. A list of data files for the information is displayed on the display device via the video controller 20 (step S64). At this time, the user can select data files from the list of data files provided by the compatible content server. After performing step S64, the support control module 10 scans an input device connected to the input controller 50 to check whether data files to be downloaded are designated from the list of data files of the content server (step S56). If there is a designation of the data files to be downloaded in step S52, the support control module 10 may request the connected content server to optimize the designated data files (step S68). 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 to the communication module 70 of the support system via the communication network. Here, the optimization process of the data file is as described in steps 54-1 to 54-7.

Then, the support control module 10 is to download the optimized data file from the content server connected via the communication network and the communication module 70 (step S70). If the optimization request for the selected data files is not requested, the support control module 10 may download the data files specified by the user from the connected content server in an unoptimized state. Subsequently, the support control module 10 causes the downloaded data files from the downloaded content server to be downloaded again to the portable device 100 via the peripheral control module 60 (step S72). By guiding the selection of content servers compatible with the portable device 100, the support control module 10 allows only data files playable on the portable device 100 to be downloaded online. Furthermore, the user can easily download the desired data files online.
