In order to transmit the media file to the final client 100, the advertisement / information server 200, the database server 300, the web server 400, and the media server 500 including the final client 100 may use one system. It must be built. In this case, the web server 400 includes a web 401 and a skin 402.

In this embodiment, the final client 100 is set as a web browser on a general PC.

The final client 100 accesses the database server 300 to search for media files (703). The database server 300 stores a search key for a media file provided by the media server 500 as a relational table.

When a result of retrieving the media file from the database server 300 comes out (704), the final client 100 accesses the web 401 of the web server 400 (805) and then removes the skin 806. Select and load 806. In this case, the web server 400 transmits the name of the media file selected by the end client 100 to the media server 500 storing the on-demand media file, thereby selecting the media file selected by the end client 100. To prepare for transmission (907). The media file is a file edited by a media file editor according to the present invention, which will be described later, and has information necessary for bidirectional internet communication.

A program for decoding a media file is installed on a PC of the final client 100, and the program is connected to the media server 500 to receive a media file selected by the final client 100 (907). do.

When the final client 100 recognizes the information set in the existing media file by the media file editor according to the present invention while playing the received media file (907), an operation related to the recognized information is performed and the final client When the 100 selects the operation, the final client 100 is connected 602 to the advertisement / information server 200 indicated by the information set by the media file editor according to the present invention to obtain necessary information.

2 is a diagram illustrating a correlation between a media file editor and a media file transfer system according to the present invention.

In this embodiment, a person who edits a media file using the media file editor according to the present invention is referred to as a user.

The user receives the uncompressed media files by the video cassette recorder / video tape recorder (VCR / VTR) 70 and the video camera 80 (67, 68).

The encoder 60 converts the uncompressed media file into a file suitable for transmission, compresses 56 and delivers it to the media file editor 50.

The media file editor 50 loads and edits information necessary for bidirectional communication in the media file received from the encoder 60.

The media file editor 50 selects a media file to be edited and then retrieves 250 advertisements and information related to an item to be edited from among various items constituting the selected media file from the advertisement / information server 200 (250). An Internet address (URL) associated with the advertisement and the information is set in the selected media file (251). In addition, coordinates, banners, search key values, voice words to be recognized, media content names, and the like, which are necessary for the Internet screening of the selected media file are set and stored in the database server 300 (350). The search key value is a search key value necessary for searching a media file before the final client 100 accesses the web server 400 and the media server 500.

Information set by the media file editor 50 is indexed into an ASF file and stored 550 in the media server 500.

3 is a diagram illustrating a configuration of a media file editor according to the present invention and a correlation between the media file editor and a peripheral system according to the present invention.

The media file editor 50 according to the present invention includes a media file loading unit 10; A time controller 11; A media screen unit 12; A banner designation unit 13; A coordinate designation unit 14; An information designation unit 15; A search designation unit 16; A speech recognition word designation unit 17; It consists of a media file conversion unit 18.

The media file loading unit 10 downloads (56) a specific media file (AVI, ASF file) to be edited by the user from the encoder 60, and the media file loading unit 10 is an open dialog ( Open the downloaded media file using Open Dialog.

The open dialog is a commonly used common dialog, which is convenient to use and can be used as a source file of a user's desired task by selecting a specific file desired without a separate implementation unit. At this time, the selected media file (source file) is opened and the total running time is set to the full length of the scroll bar. Also, various data required for moving picture control are set.

The media screen unit 12 is a part for playing the media file when the media file is selected.

The media screen 12 is the most basic part of the media file editor according to the present invention, and all the editing processes start here.

The media screen unit 12 of the media file editor 50 according to the present invention may use various types, but in this embodiment, the most popular Microsoft Windows Media Player is used. .

The media screen 12 is divided into a moving unit, an open unit, and a determination unit.

The moving unit moves a media file to a specific region, the open unit opens a media file, and the determination unit determines whether the media file is operated.

When the moving unit moves the media file to a specific area, the moving unit finds the current position among the built-in functions of the Windows Media Player ActiveX Control (hereinafter referred to as "WMPC") and its current position value. To the slider control. This allows the user to view the entire media file duration in a GUI environment.

The open unit reads a script file while opening a media file.

Normally, the file will be controlled using a database. However, the media file editor 50 according to the present invention reads a file using a structure of Visual C ++ because the script file does not have a large role and a small size. . Of course, the sorting and searching functions were also used using related algorithms (sequential search and sequential sorting).

If the file read by the open unit is a script file that has been previously edited, the open unit searches for the data in the file under a specific condition (the edit time should not exceed the total running time of the media file) and the condition is not satisfied. Find and re-edit and delete data.

The determination unit determines whether the media file is in operation and compares the media file in a playing state and a pausing state to perform a corresponding operation. In other words, when the media file is displayed, no special work is performed, but when the media file is stopped, the editing time is corrected or the scroll bar is used to move to a specific position.

The time controller 11 displays the current running time in an Edit Control in the time controller 11 when the user opens and plays the media file after connecting the media file to the media screen 12. That's the part.

While the media file is being played, no modifications related to the current running time can be made, so the media file must be stopped to edit the media file.

When the media file stops, the media file progress time stops and changes to the modification mode. At this time, the user gives a modification point with the mouse to the time at which the current media file is being displayed and inputs the editing time desired by the user. At this time, the input time should not exceed the total running time of the media file. The time controller 11 displays an error message when the user incorrectly inputs an edit time and gives a re-entry focus to a corresponding edit control area.

The coordinate designator 14 is a part that links the screen coordinate area of the specific time zone and the relevant site when the media file is displayed.

The user stops the media file at the time of editing and captures the frame in the media file. At this time, the frame is specified in units of a single frame. The specified file is composed of a file format in the DIB (Device Independent Bitmap) format. The dragging area is displayed when the mouse is dragged by converting the DIB (Device Independent Bitmap) format file into a BMP format file again.

When the coordinate designator 14 is selected from a menu, the point of the mouse cursor changes to a capture mode. When the user drags a specific area to edit with the mouse, the mouse's coordinates are displayed in the corresponding Edit Control and the selected area is displayed as a rectangle on the screen. The designated start coordinates and the designated end coordinates can be modified and deleted later.

Multiple coordinates can be set on one screen, but it is important to note that when setting multiple coordinate values, the coordinate values of each other should not overlap. The user distinguishes the start time and the end time of the coordinate designation by giving the coordinate designation start command and the coordinate designation end command. The reason for distinguishing the start time and the end time is to prevent the set coordinates from lasting until the end of the media file and to automatically disappear the image in the coordinates.

When the final client 100 plays the media file and selects it, and selects a specific area on the screen (the item among the items constituting the media file, the final client wants more specific information), the area that has already been coordinated is distinguished from the surroundings. At the same time, the colors are reversed and linked to related sites through a dedicated browser.

The banner designator 13 connects a media file with a specific product or banner image.

The specific product or banner image to be associated with the media file may be a local area or a corresponding site on the web server 400. However, since the media file editor 50 according to the present invention mainly edits on the web without the work in the local area, the media file editor 50 uses the Web Browser Control (WBC) to the server 201 of the site. By moving (251) a specific product or banner image.

In this case, in order to determine whether the banner image selected by the user is correctly selected, a preview function is provided so that the banner image can be previewed in a reduced size when the user selects a specific banner image from the server of the corresponding site. If you make a mistake, you can, of course, reselect. Types of images that can be used are GIF, JPG, BMP, etc. In general, GIF is mainly used in the media file editor according to the present invention because GIF is used as an image file.

When the coordinate designation unit 14 is selected, the coordinate designation unit 14 substitutes for the banner designation unit 13.

The information specifying unit 15 is a part that connects the media file and the information.

The realm with connection information can be either a local realm or a corresponding site on a web server. However, since the media file editor according to the present invention excludes work in the local area and mainly edits on the web, the media file editor moves to the corresponding site 202 by using a web browser control (WBC) to display specific information. Link 251.

At this time, in order to determine whether the information selected by the user is correctly selected, a preview function is provided so that when the user selects an address (URL) related to specific information from the corresponding site or server, the corresponding site of the relevant information or related address (URL) The content can be previewed in a reduced size. If you make a mistake, you can of course reselect it. Information files that can be used are HTM and HTML.

When the coordinate designator 14 is used, only the information designator 15 can work.

The search designation unit 16 designates a search word necessary for searching for a media file such as a video or music.

When the search term setting menu is selected in the media file editor 50 according to the present invention, a dialog box of a modeless form is generated. In the dialog box, a search word is input as text. In addition, the time specified in the search word is input using a text or a slider bar of a main view.

The search term is made into a relational table of a database using an ODBC function and stored in a search database server 302. In a media file providing service, the media server 500 interworks with the search database server 302 to control a service.

The end client 100 retrieves the contents of the media to be watched by the key value. The key values used at this time are the values input from the search designation unit 16 of the media file editor 50 according to the present invention.

The search term is searched in the relational table of the database and the search result list is displayed on the web screen according to the key value. When the final client 100 selects a portion of the media file that is being played and wants more specific information, the media server 500 interworking with the selected portion selects a specific information file related to the selection made by the final client 100. The media file is delivered to the final client 100 at a specific time when the media file is played.

The speech recognition word designation unit 17 is a portion for designating a word required for speech recognition when playing a media file such as a video or music.

In the media file editor 50 according to the present invention, a voice recognition word setting menu is selected to generate a dialog box and a text is input to set a word to be recognized. In addition, information required when a word is recognized is input together. The input word is made into a relational table of a database using an ODBC function and then stored in the speech recognition word database server 301.

The speech recognition word designation unit 17 performs a necessary task when a specified word is recognized in association with the media server 500 when a media file providing service is performed.

The final client 100 selects a word to be recognized through a combo box on the screen when the screen is played. When a specified word is recognized when playing a media file such as a video or music, the designated task is performed in the media file editor 50 according to the present invention.

The media file converting unit 18 is a part that performs a final operation of making the work done in all the configuration units into a script file and setting it in the media file.

The user completes the editing process by selecting the command to be combined with the script file according to the file type of the media file.

In this case, the media file editor according to the present invention selectively sets the bit rate using the IWMStreamConfig interface of the Windows Media Format SDK and generates and indexes the media file using the IWMWriter and IWMIndexer interfaces. do.

By creating a variety of media files with bit rates suitable for 56K modems and leased lines, users can select and play media files that match their PC communications bandwidth.
