The present invention relates to a terminal support system for transmitting a video file and a subtitle file corresponding thereto, a terminal, and a file transmission method thereof.

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.

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 a video file such as a movie. And a subtitle file for the video file.

Hereinafter, with reference to the accompanying drawings a specific embodiment of the terminal support system and the terminal according to the present invention will be described in detail.

Hereinafter, specific embodiments will be described in detail with reference to the accompanying drawings.

1 is a block diagram schematically illustrating a support system for a terminal according to a specific embodiment of the present invention. The support system for a terminal of FIG. 1 includes a video controller 120, a main memory 130, a hard disk 140, an input controller 150, a peripheral control module 160, and a communication module connected to the support control module 110. 170 is provided. The support control module 110 supports the terminal 200 connected to the peripheral control module 150. In detail, the support control module 110 includes a terminal 200 for downloading and updating an update program to the terminal 200 for maintenance and function update of the terminal 200, and for viewing or listening to video and / or sound information. Downloading of the playable data file into the furnace is performed. In addition, the support control module 110 downloads a program for registering and updating user information and a reproducible data file through the communication module 170. The support operation of the support control module 110 will be described in detail with reference to the flowchart shown in FIG. 3. In addition to the support operation, the support control module 110 may control 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. Perform data operations and logic operations. For this purpose, the support control module 110 includes a North Bridge 114 and a South Bridge 116 connected in series to a Central Process Unit (hereinafter referred to as "CPU") 112. ).

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

North bridge 114 relays bidirectional data communication with CPU 112 and each of video controller 120 and main memory 130, which are peripherals that operate relatively fast, including south bridge 116. In addition, under the control of the CPU 112, the north bridge 114 controls the video controller 120, the main memory 130, and the south bridge 116.

South Bridge 116 is a collection of registers that manages the input and output of each of the relatively slow peripherals. The south bridge 116 provides bidirectional data between the hard disk 140, the input controller 150, the peripheral control module 160, and the communication module 170, and the CPU 112 connected via the north bridge 114, respectively. Relay the transmission. In addition, the south bridge 116, under the control of the connected CPU 112 via the north bridge 114, the hard disk driver 140, the input controller 150, the peripheral control module 160 and the communication module. Control 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 (ie, the CPU 112) to be displayed on a display device such as a cathode ray tube or a liquid crystal display panel. To this end, the video controller 120 may be connected to the north bridge 114 by an accelerated graphic port (AGP).

The main memory 130 provides a workspace for the support control module 110, specifically, the CPU 112. In other words, the main memory 130 temporarily stores data processed or to be processed by the CPU 112 in the support control module 110. To this end, main memory 130 is connected to 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 ROM. The operating system stored in the hard disk 140 is uploaded to the main memory 130 by a system booting operation. Various application programs stored in the hard disk 140 are also uploaded to the main memory 130 and executed by the user's selection.

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 peripheral control module 160 and the terminal 200 may be connected by various interface devices, but in the present specification, the peripheral control module 160 may be connected to the interface device by a universal serial bus (USB). The connection with the terminal 200 to be supported will be described as an example.

The communication module 170 relays bidirectional communication between the support system and the communication network. Specifically, the communication module 170 transmits data from the public telephone network or the local area network to the support control module 110 (ie, the CPU 112 via the south bridge 116 and the north bridge 114). Or transmit data from the support control module 110 (ie, transmitted from the CPU 112 via the north bridge 114 and the south bridge 116) to the public telephone network or 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, or a mobile phone or portable receiver having a playback function (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. 2.

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

As shown in FIG. 2, the terminal support system 100 includes a support control module 110 as illustrated in FIG. 1. In addition, 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, and thus, a USB interface device may be applied.

On the other hand, the terminal 200 is configured to include 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 play request from the user. The method of reproducing the data file will be described in detail below in describing the operation of the present invention.

The main controller 210 is provided with a connection interface 280 to enable data communication with the terminal support system 100 in response to the connection interface 180. Therefore, if the connection interface 180 is a USB interface device, the connection interface 280 also becomes a USB interface device.

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

On the other hand, 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 feature table storing the characteristics of the terminal.

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

As shown therein, 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. 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.

Therefore, when the subtitle file is transmitted to the terminal 200, the support control module 110 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 caption 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 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.

Meanwhile, the support control module 110 checks whether the connected terminal 200 supports a subtitle file and does not support the subtitle file (for example, a device such as an MP3 is not generally supported). In this case, the converted subtitle file is combined with a video file (hereinafter, the combined file is referred to as a 'synthesis file') and transmitted. In this case, the subtitle file is preferably pasted into the video file using a filter.

In addition, the support control module 110 is a terminal in which the connected terminal 200 supports a subtitle file, and the file data (referred to as an image file) to be transmitted can be converted to insert a subtitle file into the image 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 "bundled file").

The method of generating the bundled file will be described in detail below in describing the operation of the present invention.

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

First, the support control module that receives a data file transfer command from a user to the terminal 200 determines whether a subtitle file exists in the data command to be transmitted (S110 and S120). Herein, the present invention is applied at the time of transmission of a video file, and it is assumed that the data file to be transmitted is a video file. In addition, the inclusion of a subtitle file in the data file is used to mean a case in which a subtitle file having the same file name as the transfer command video file exists in the same folder.

This is because there is no subtitle when the data file is a domestic video file, so it is not necessary to go through each step of the present invention. Therefore, if there is no subtitle file as a result of the determination of step 120, the data file is directly transmitted (S150).

Next, when the caption file is included in the data file, it is determined whether the caption information exists on the feature table stored in the connected terminal 200 (S130). 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 subtitle information exists, the support control module 110 converts the format of the subtitle file to correspond to the subtitle information (S134). 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 (S136). 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 caption file is changed, it is determined whether the next connected terminal 200 supports the caption file (S140). Here, a model that does not support the subtitle file refers to a terminal 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 terminal, the video file must be made by applying the subtitles to one video file.

Therefore, when the terminal 200 does not support the subtitle file as a result of the determination of step 140, a combined file is generated by combining the subtitle file with the video file (S146). Then, the synthesized file integrated with the subtitle is transmitted (S150).

If it is determined in step 140 that the connected terminal 200 supports the caption file, it is determined whether the type of the video file to be transmitted is a file capable of caption insertion (S142).

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

Of course, the format of the representative video file will support the conversion of the support control module, but not all of the video files of a number of non-representative formats go through the above steps.

Subsequently, if the video file is a video file of a caption insertable format, a caption file is added to the video file to generate a bundled file (S150).

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

After the bundle file is generated, the generated 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.

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, looking at the data structure of the video file, the data has a packet that stores the actual DATA, and a header and tail attached to the front and rear ends of the packet, respectively.

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

In this case, the structure of the header or tail is slightly different depending on the type of each video file. Therefore, the support control module 110 should know the structure of the header or tail to insert the caption data according to the representative video file type.

At this time, the video control file having a header or tail structure that the support control module 110 does not grasp is determined by the support control module 110 not to allow subtitle insertion.

FIG. 5B is a diagram showing a position at which subtitle data is inserted into a header of an AVI format file among video files.

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

Hereinafter, a method of playing the received video file by the terminal 200 receiving the video file will be described.

6 is a flowchart illustrating a method of playing a video file according to a specific embodiment of the present invention.

As shown, the terminal 200 according to the present invention stores the video file received from the terminal 200 support system in the storage unit 230 (S210). In this case, when the subtitle file is received together, the received subtitle file is also stored together with the video file.

If there is a playback command for the video file, it is determined whether the video file is a converted file with subtitles inserted (S220). The determination is made by looking at the header or tail portion of the video file.

In this case, in the case of the video file, the caption data inserted in the header or tail of the video file is extracted and stored in the buffer (S230 and S232). Of course, it is also possible to generate one subtitle file by extracting all the subtitle data.

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

On the other hand, if it is determined in step 220 that the video file is not a converted file, it is determined whether a caption file matching the video file exists in the storage unit 230 (S240).

Since the subtitle file exists, the subtitle file and the video file are played together (S234).

However, if the subtitle file does not exist, the video file is a video file without original subtitles or a video file generated by combining subtitles with the video file (synthesis file, see step 146). It is played back (S242).

In the following, it will be examined how the present invention operates within the overall single-head support method of the terminal support system.

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

The support control module 110 periodically waits while monitoring the peripheral control module 160 until the terminal 200 having a playback function is connected to the peripheral control module 160. When it is detected that the terminal 200 is connected to the peripheral control module 160, the support control module 110 is as shown in Figure 3 stored in the terminal 200 via the peripheral control module 160 The table is read (step S312). In addition, the support control module 110 supplies the 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 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 110 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 150. It waits until a command specifying which one is input (steps S316 to S324).

When the designation command of the table update mode is input from the input controller 150 in step S316, the support control module 110 may update information by supplying information on the updatable items to the display device via the video controller 120. The items are displayed on the display device (S326). The support control module 110 scans an input device connected to the input controller 150 and checks whether update information to be updated by the user is input (step S328). If the update information is input in step S328, the support control module 110 loads the input update information of the user into the terminal 200 connected to the peripheral control module 160 to correspond to the corresponding item on the feature table in the terminal 200. The information may be updated by the user's input information (step S330). At this time, the 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 update of the feature table by the user may prevent the use of the terminal 200 by another person. In addition, initial language and frequency modulation information may be updated among items on the feature table in the terminal 200. The initial language may be reset by the user or the distributor as appropriate for the country in which the terminal 200 will be used, and the frequency modulation information may be reset by the user or the distributor according to the country or environment in which the terminal 200 will be used. .

When the command for specifying the firmware update mode is input from the input controller 150 in step S318, the support control module 110 searches for the manufacturer name and model name of the terminal 200 in the read feature table (step S332). The searched manufacturer's name of the terminal 200 is used to access an online site of the manufacturer of the terminal 200 through a communication network connected to the communication module 170 (step S334). In addition, the support control module 110 downloads the firmware corresponding to the model name retrieved from the manufacturer's online site (S336). At this time, the downloaded firmware is temporarily stored in the main memory 130. Subsequently, the support control module 110 downloads the downloaded firmware back to the terminal 200 connected to the peripheral controller 160 so that the firmware in the terminal 200 is updated (step S338). By updating the firmware in the terminal 200, maintenance of the terminal 200 may be facilitated, new functions may be easily added to the terminal 200, or unstable functions may be easily reinforced.

When the designation command of the online registration mode is input from the input controller 150 in step S320, the support control module 110 searches for the manufacturer name and serial number of the terminal 200 in the read feature table (step S340). . The searched manufacturer's name of the terminal 200 is used to access the online site of the manufacturer of the terminal 200 through a communication network connected to the communication module 170 (step S342). In addition, the support control module 110 transmits the retrieved serial number to the online site of the manufacturer of the terminal 200 so that the serial number of the terminal 200 is registered at the online site of the manufacturer (step S344). Subsequently, the support control module 110 scans an input device connected to the input controller 150 and checks whether information related to the user (that is, user information) is input (step S346). When the user information is input in step S346, the support control module 110 transmits the input user information to the online site of the manufacturer of the terminal 200 through the communication module 170 and the communication network, so that the user information is sent to the online site of the manufacturer. (Step S348). The user information includes a user name, a user address and a phone number of the terminal 200. Registration of such user information enables tracking of the lost or stolen terminal 200 to prevent loss and theft. In addition, registration of the user information enables tracking of illegal terminals 200 distributors, such as sales of stolen products and dumping sales of wholesalers with the removal of serial number labels. Furthermore, after the online registration of the user information, the support control module 110 may download a coupon from the manufacturer's online site via the communication network and the communication module 170. The downloaded coupon may be stored in the terminal 200 by the support control module 110 via the peripheral control module 160. 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 S322, the support control module 110 may transmit data regarding video and / or sound information stored in the hard disk 140 based on the read DRM information on the feature table. Search for data files that can be played on the terminal 200 among the files. In addition, the support control module 110 prepares the searched 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 a list of playable data files (S350). step). Subsequently, 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 list of data files (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 be read from the hard disk 140 so that the read data files are suitable for being reproduced by the terminal 200. (Step S354).

At this time, in the optimization of the step 354, when the data file is a video file, the method described with reference to FIG. 4 is applied.

Thereafter, 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). As such, only data files of the releaseable DRM means can be selected among the data files for the image and / or sound information stored in advance in the hard disk 140 so that the user can easily download the playable data file to the terminal 200. To make it possible.

When a command for designating the online downloading mode is input in step S324, the support control module 110 searches for DRM information in the read feature table (step S358). Based on the retrieved DRM information, the support control module 110 creates a list of content servers compatible with the terminal 200 (step S360). In addition, the support control module 110 scans an input device connected to the input controller 150 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 S362). If there is a designation of the content server to be accessed in step S362, the support control module 110 connects to the selected content server via the communication module 170 and the communication network, and the video and / or sound provided by the connected content server. The list of data files for the information is displayed on the display device via the video controller 120 (step S364). At this time, the user can select data files from the list of data files provided by the compatible content server. After performing 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 list of data files 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 the connected content server to optimize the designated data files (step S368). If there is an optimization request of this data file, the content server optimizes the requested data files and allows the optimized data files to be transmitted to the communication module 170 of the support system via the communication network. The optimization process of the data file is as described with reference to FIG.

In addition, the support control module 110 may download the optimized data file from the content server connected through the communication network and the communication module 170 (operation S370). If the optimization request for the selected data files is not requested, the support control module 110 may download the data files specified by the user from the connected content server in an unoptimized state. Subsequently, the support control module 110 causes the downloaded data files from the downloaded content server to be downloaded back to the terminal 200 via the peripheral control module 160 (step S372). By guiding the selection of content servers compatible with the terminal 200, the support control module 110 allows only data files playable on the terminal 200 to be downloaded online. Furthermore, the user can easily download the desired data files online.

As described above, the program implementing the support method for the terminal may be stored in the terminal instead of being stored in the hard disk 140 of the support system shown in FIG. 1. In this case, the terminal support system can be replaced with a conventional personal computer. When the terminal is connected to the support system (ie, a 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 (ie, the personal computer) and then returned to the main disk. The memory 130 may be uploaded and performed by the support control module 110.
