According to the present invention, there is provided a network comprising: generating a plurality of still image frames corresponding to each scene from predetermined moving image video data, and sequentially providing the still image frame through the network. It is achieved by the image providing method through.

Here, if a plurality of pages in which a plurality of the still image frames are arranged in sequence is provided and the still image frames are provided in page units, the user may enjoy a hobby such as watching a movie or the like in the form of a cartoon.

In addition, when displaying subtitles in each frame or allowing audio data to be played back corresponding to the selected frame, multimedia information can be more faithfully reproduced. In particular, when the audio data is reproduced, the audio data can be continuously performed in the order of frames, thereby realizing the realism of actually watching the video.

On the other hand, according to another field of the present invention, an image providing system for providing an image from a server to a client via a network, comprising: a frame storage unit for storing a still image frame corresponding to a plurality of scenes in a predetermined moving image video data; An image data storage unit for storing related data corresponding to each of the still image frames, and an interface unit for sequentially providing the still image frame and the related data through the network according to a request from the client. Provision system is provided.

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

1 is a block diagram of a network configuration including an image providing system according to the present invention. In the network configuration shown in this figure, as in the usual case, the server 1 and the plurality of clients 2 are connected by a network communication means such as a LAN or the Internet 3. In the case where the network communication means is the Internet, the server 1 is called a web server and has an interface for connecting to the Internet. In each client 2, a web browser program such as Netscape, Microsoft, or Explorer is operated.

The server 1 includes a video list DB 11 to be provided to the client, a page DB 12 for storing pages consisting of still image frames, and an audio DB 13 for storing audio data and subtitle data corresponding to each frame, respectively. And a caption DB 14. And, if necessary, it may have a video storage unit 15 for providing a video. The interface of the server 1 retrieves the page of video selected by each client 2 and the related audio or subtitle data from each DB and provides it via the Internet 3.

2 is a flowchart showing a page creation process consisting of a still image frame. First, a moving picture video data or multimedia information to be provided, namely a movie or a drama is prepared (S1). From the video data, a plurality of instant scenes are selected according to an appropriate time interval or importance and a still image frame of the scene is created (S3). If there is dialogue for each still image frame, subtitles are created and audio data is edited (S5). Subtitles are written in Korean and / or English, for example, and are stored in a separate DB. In some cases, the subtitles may overlap the still image frame. The audio data is edited and stored for a predetermined time, preferably a time corresponding to the time until the scene of the next frame, which is reproduced from the original video data corresponding to the scene of the still image frame.

When the creation of the still image frames is completed or a certain number of the still image frames are obtained, pages are created by reducing or enlarging and arranging them as in a comic book (S7). An example of the page thus created is illustrated in FIG. The number of pages consisting of the still image frames depends on the size of the video data, the number of the still image frames extracted therefrom, and the number of the still image frames arranged in the unit page. It will be around 200 sheets to be written enough.

The page, caption, and audio data created as described above are stored in a database so as to be appropriately provided according to a client's request (S9).

3 is a flowchart illustrating an execution process of an image providing system according to the present invention. When the client connects to the server and undergoes a certain recognition process, a list of videos that the server can provide is presented, for example, a list of movies such as "Dead Poet Society", "Benhur", "Ten Ten", and the like. The client selects a desired video from the list (S20). When the video is selected, the server transmits the default page of the video, usually the first page, to be displayed on the client (S22). If there are a large number of pages, the client can select an arbitrary page (S24), and accordingly, the server provides the selected page for display (S26). When the selected page is displayed, a subtitle related selection such as subtitle display, subtitle language selection, subtitle display method, etc. displayed at an appropriate position on the screen is performed (S28), and then audio display and audio display method are selected (S30). The language of the subtitles can be selected, for example, either English or Korean, or the simultaneous display. The selection of the subtitle display method can be overlapped on each still image frame or displayed in a separate space. Or selecting whether to display the subtitles collectively in all frames or only the selected frames, or to automatically display the subtitles at predetermined time intervals. The audio display method may select whether to play the selected frame only once or automatically continuously. In accordance with all the conditions selected as described above, the page is provided, the subtitles are displayed, and the audio is reproduced (S32).

4 is an exemplary view of a page screen provided according to the present invention, which is a page of a still image frame for some sections of the movie "Society of the Dead Poets". In one page 21 displayed on the screen, a plurality of still image frames 23 are appropriately arranged like a cartoon. Each still picture frame represents each scene of the video data and is sequentially arranged in accordance with the development of the content of the video data, and is edited in different sizes according to the importance of the content. In each still image frame, dialogue in the scene overlaps with each other in the form of subtitles.

At the top of the page 21, a caption selection column 27 and an audio selection column 29 are arranged so that the caption display and audio reproduction method can be selected. The client can select whether or not to display the subtitle through the subtitle display column 27 and the audio selection column 29 to select whether to display the audio and to continuously play the audio.

At the bottom of the page, control icons 31 used for normal video playback are arranged to control page switching. Through these icons, the control such as forward and backward and stop can be conveniently performed as in the same case as when playing a normal video. In addition, the page display unit 33 is provided, it is possible to confirm the total number of pages and the position of the current page, through which it is possible to move to the desired page as needed.

In the above-described and illustrated embodiments, although a plurality of still image frames have been edited into pages and transmitted and displayed in units of pages, the still image frames may be individually or plurally transmitted to be adaptively displayed according to the screen situation of the client side. . Although not mentioned in the above-described embodiment, it is possible to select a period of frame switching and page switching in automatic continuous caption display and / or audio reproduction.

In addition, although the still image frame has been described as being created and stored in advance, the same result can be obtained even if the still image frames are extracted and provided in real time from the video data of the video storage unit stored in the server side in real time. In this case, the client side can select the time interval between the still image frames, that is, the extraction interval between scenes. When a frame is selected, a moving picture may be provided from the scene of the frame to the scene of the next frame.

As described above, according to the present invention, the amount of data to be transmitted and processed can be reduced by providing a video composed of a large amount of data in the form of an extracted still image, and a movie can be viewed in the form of a cartoon. You can enjoy a new hobby that you could not feel in the media. In addition, it can be used not only for current events or promotion of new movies, but also for language learning.
