The storage unit 110 stores at least one image file such as a picture or a picture, at least one voice file, and a metadata file mapped to the image file. In addition, the storage unit 110 stores information about a program for editing and executing metadata. An image file is a file that converts a photo or a picture into a format that can be recognized by the system (for example, a jpg, png, or bmp storage file), and an audio file is a format in which the system can recognize a song or performance (for example, mp3, wmv, etc.). The metadata file is a file including output operation information on the image file when the image file is to be displayed. Output operations for image files include the display of descriptive text, the output of voice files, and the display of hand writing fonts. The handwriting font will be described later. The metadata file includes at least one output operation information field for storing output operation information. For example, the output operation information field may be a file (File_name) field including information on a target image file name to be displayed, and a group (Group_name) including information for classifying a plurality of image files according to characteristics. Field, a Metadata_display_on_off field that contains information about whether to apply the output action information that the metadata file includes to the image file, a description text for that image file, a Display_string field that contains output action information, and a description text for the image file. Display_string_size field containing information about the size, Display_string_font field containing information about the descriptive font of the image file, Display_string_impact field containing information about the special effects to be processed in the descriptive text, and description text display location in the image file Dis contains information about The play_string_position field, the Display_string_color field containing information about the color of the description text of the image file, the hyperfile (Hyper_link) field for defining information about the display output behavior, the audio file output, and the handwriting font. A hyperlink option (Hyper_link_sub_filed_option) field including information for giving an option to the display output operation information is included. Hyperlink options include the output level of the voice file and the transparency of the handwriting font.

 The user input unit 120 is implemented with a mouse, a keyboard, and the like, and receives a user request from the user. User requests include metadata editing requests, metadata execution requests, and metadata file selection requests.

The metadata editing unit 130 receives a metadata editing request from a user and defines output operation information of an image file in metadata. Referring to FIG. 3, the metadata editing procedure first receives the metadata editing request and executes the metadata editing program stored in the storage 110 (S110). The metadata editing unit 130 receives a metadata editing request and selects a metadata file to be edited (S120). The user defines the output operation information to be performed on the image file included in the metadata through the user input unit 120 in the output operation information field of the metadata file (S130). When editing is completed, the metadata file is stored (S140).

The metadata execution unit 140 receives a metadata execution request from a user and drives the metadata file mapped to the image file. The operation of the metadata file includes a display of an image file included in the metadata file and various output operation processes for the image file. Referring to FIG. 4, the metadata execution procedure 140 first receives a metadata execution request and executes a metadata execution program (eg, an electronic frame viewer program) (S210). The metadata execution unit 140 receives a user request and selects a metadata file to be executed (S220). The metadata execution unit 140 analyzes information of each output operation information field included in the selected metadata (S230). The metadata execution unit 140 displays an image file of the corresponding metadata and performs various output operations included in the metadata (S240).

The output unit 150 provides the user with multimedia contents included in the metadata file. The multimedia content includes an output operation for an image file, a voice file, and an image file included in the metadata file. For example, the output unit 150 may include a display and a speaker, and output an image file, an explanatory phrase for the image file, a handwriting font display, and a voice file through the display.

The controller 160 controls the storage of the image file, the voice file, and the metadata file mapped to the image file of the storage 110, the user input input of the user input unit 120, and the metadata editing unit 130 of the metadata file. Controls the metadata output operation information definition, controls the execution of the metadata file mapped to the image file of the metadata execution unit 140, and controls the provision of the multimedia content of the output unit 150.

Referring to another embodiment of the present invention with reference to Figure 2, the output operation information field of the metadata file By using a group field, one of the items, several image files can be displayed in a circular manner for a certain time. Only image files included in the metadata file having the same group field value may be displayed. When a plurality of image files are stored in an internal storage medium or an external storage medium of a multimedia content service system, only image files set as, for example, "Jeju Island Tour Photo 2008" in the metadata group field may be cyclically displayed. Can be.

In addition, in a multimedia content service system supporting a touch screen, a handwriting font may be input and stored using the touch screen. The handwriting font may be defined in the hyperlink field of the metadata file so that the handwriting font is overlapped when the image file is displayed. For example, if you want to provide users with their own text or pictures along with a specific image file, you can enter a handwriting font such as "Happy birthday to your beloved daughter." You can save my message.jpg for your elder birthday. Happy Birthday Photo.jpg mapped to an image file named Happy Birthday Photo.jpg Set my message for Happy Birthday.jpg in the hyperlink field of the metadata file and set the alpha-blending option in the Hyperlink Options field. When set, the image file can be displayed. "Happy birthday to my dear daughter.jpg" is displayed on the display. The alpha-blending effect is displayed using a frame buffer. In the graphics engine (graphic engine means commercial version or open source version such as QT / GTK / Evas), the Transparency or Opacity is adjusted using TRGB (Transparency, Red, Green, Blue). Can be used to display handwriting fonts in the original image file. Alpha-blending provides an application interface call (API) that allows you to set transparency in steps. The meaning of the steps here is that if you set the level from full transparency to full opacity, and enter transparency from '0' to '256', the transparency of the handwriting font overlapping part or all of the original image file will be reflected differently. Therefore, when displaying my message for eldest birthday happy birthday.jpg in the image file of the eldest daughter happy birthday photo.jpg of the above-described embodiment, the transparency or opacity value is used to indicate the degree of alpha-blending effect. Different effects can be displayed on the screen.

The multimedia content service method of the present invention first selects at least one image file stored in the storage 110. The metadata editing unit 130 receives a user request and defines output operation information of the image file in a metadata file corresponding to the image file. The metadata editing unit 130 drives the metadata file mapped to the image file when executing the selected image file according to the user's request. The output unit 150 outputs the image file based on the output operation information of the corresponding metadata file.

In the present invention, the metadata file can be edited using a PC as well as a multimedia content service system. Therefore, image files can be transferred between users using a multimedia content service system using MMS (Multimedia Message Service) or shared using an external storage medium (USB memory stick, SD / MMC card). This can be useful for improving the metadata editing program's additional functions.

In the present invention, the multimedia content service system may be a video phone.
