Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The moving picture retrieval apparatus of the present invention can be implemented in any video storage medium, such as a DVD (1) or a device capable of playing a moving picture file, containing a moving picture created from a moving picture character recording file. An example of such a device will be described with reference to FIG. As shown, a CPU 2 for creating a search word describing characteristics of a specific scene of a specific movie, for example, a specific movie, into a text recording file, and controlling overall search function of a specific moving picture using the created search word file, and the CPU 2 Downloading the program to be loaded from the ROM 3 in accordance with the function load control signal of the CPU 2 and the ROM 3 for loading the corresponding program in accordance with the moving picture character recording file creation and moving picture search function control signal RAM 4 which loads the data currently being operated, and checks according to a control signal of a moving picture character recording file and moving picture search function of the CPU 2 And a moving picture reproducing unit 5 for creating a color word character recording file or reproducing a moving picture corresponding to the search word.

One end of the video player 5 is connected to a display 6 for displaying a video according to a display control signal of the CPU 2, and one end of the CPU 2 is connected to a keyboard 7. .

Next, the method of the present invention applied to the video search apparatus of the present invention as described above will be described.

The method of the present invention proceeds to the character recording file creation function setting determination step (S2) in the initial state (S1) as shown in Fig. 3 to determine whether the search word character record file creation function is set in the current system. When the character string file creation function is set in the current system as a result of the determination during the character log file creation function setting determination step (S2), the process proceeds to the keyword string file creation step (S3) to explain the specific screen of the moving image. Create a search query character log file.

That is, when the user wants to create a search word character recording file by using the DVD 1 or the file containing the video, the corresponding function command is set by the keyboard 7 of the video search apparatus 8 of the present invention. Then, the CPU 2 of the video retrieval apparatus 8 recognizes the search word character record file creation command set by the user, reads the corresponding creation program from the ROM 3, and loads it into the RAM 4. Then, when the user inserts a video (eg, a DVD 1 or a file containing a movie) that the user wants to create a search word character recording file into the video player 5, the CPU 2 recognizes the video and plays the video player 5. Playback is performed to display the video currently being played on the display 6.

In this case, the CPU 2 displays a video currently being played on the display 6 and inputs a search word for a specific scene of the currently played video image through the keyboard 7 using FIG. 4. As shown in Fig. 1, a text recording file containing a search word associated with a specific scene is created.

Here, the character recording file can be produced, for example, as a subtitle file of " *. Smi "

For example, when a specific screen of a moving picture reproduced on the display 6 is a scene in which "two cars run a car race", the user may input a search word such as "car race" which describes the characteristics of this particular screen. ), The CPU 2 generates this character search file as a subtitle file, for example, "* .smi" in synchronization with the specific screen, and stores it.

On the other hand, if it is determined during the character recording file creation function setting determination step (S2), if the query character record file creation function is not set in the current system, proceed to the video search function setting determination step (S4) and the video search function in the current system. Determine if this is set. At this time, when the video search function setting determination step (S4) is determined, if the video search function is set, the video search function input determination step (S5) is performed to execute the video search function and determine whether a search word has been input from the user. .

Accordingly, when the search word is not input from the user as a result of the determination during the video search word input determination step S5, the process returns to the video search word input determination step S5 again and repeats the loop. However, when the search word is input from the user as a result of the determination during the video search word input determination step (S5), the process proceeds to the video search execution step (S6) and includes the search word currently entered in the text record file and corresponds to similar characters. After searching all the specific screens of a moving picture, a list of the specific screens currently searched is displayed.

Then, after the video search execution step (S6) proceeds to the selected video playback step (S7), if a specific screen is selected from the searched video list to play the screen according to the set display method.

In addition, if it is determined during the video search function setting determination step (S4), if the video search function is not set, the process proceeds to the search term correction function input determination step (S8) to determine whether the search word correction function is set in the system. At this time, if the search word correction function is not set in the system as a result of the determination during the search term input function determination step (S8), the current operation state is terminated. However, if the search term correction function is set in the system as a result of the determination during the search term correction function input determination step (S8), the user proceeds to the search term correction function execution step (S9) to search the user's search word on the text record file for the specific screen being played. Modify the new search word set by.

In other words, when a user wants to search for a specific screen of a desired video, the user first sets a corresponding function command through the keyboard 7 and plays a video of a DVD or a file containing a video containing a text recording file. Insert or open the part (5). Then, the CPU 2 of the video search apparatus 8 recognizes the video search command set by the user, reads the search program from the ROM 3, and loads it into the RAM 4. Then, the CPU 2 requests the user to input a search word for video search on the display 6 according to the search program. At this time, when the user inputs a search word through the keyboard 7, the CPU 2 recognizes this and searches for a specific screen of all videos corresponding to the search word and a character similar to the search word in the text record file, and the searched specific The list for the screen is displayed on the display 6.

For example, if the search term is "battle scene", the CPU 2 searches all of the specific screens recorded as "battle scene" in the character recording file and displays the "battle scene" on the display 6. List all applicable scenes. At this time, when the specific screen desired by the user clicks on the corresponding list of the display 6, the CPU 2 recognizes it and plays it through the video player 5 to display it according to the display method set on the display 6. . In this case, since the display method may be changed by a program designer, the display method of the present invention may also show only a scene in which a user clicks on a specific screen of the currently searched moving picture or sequentially play it.

On the other hand, if the user wants to modify the search word of the specific screen while watching a video for the specific screen as described above, the search term correction command can be set through the keyboard 7 and newly input the search word. Then, the CPU 2 modifies the search word newly input by the user in the corresponding character recording file corresponding to the specific screen.

Here, although the description of the present invention has been described with an example of a DVD, the present invention is not limited thereto, but may be applied to all video storage media.

As described above, the present invention allows a user to request a specific moving picture by creating a video search word describing a specific moving picture as a text recording file and searching for the moving picture text recording file to display the corresponding moving picture information when the video search word is input. Since all of them are searched for and displayed, there is an advantage of significantly improving the moving picture retrieval characteristic.

In addition, according to the present invention, since a video viewer can immediately search for and view a desired video without a separate memo when viewing the video, the user convenience of moving picture information search is also significantly improved.
