On the other hand, the image information output unit 108a is provided with a specific logo or picture at the time of initial execution, but after the video is played, the initially provided logo or picture does not appear.

In addition, the key module 110 is a video file open, play, pause, next file, previous file, stop, map open, map close, playback time, progress time, progress slider, speed slider and the like for the button This is made up.

A playback method using the playback system of the moving picture information configured as described above will be described with reference to FIGS.

Here, in the following description of the present invention, a playback process by a video file for a desktop is described.

First, in order to produce the video file, raw data consisting of video data and audio data must be created as an AVI file, which is an extension indicating a video file. Image data of a moving object taken from a stationary state through a method such as rotating the camera (e.g., sunrise, sunset, plant growth, etc.) or moving to a main shooting place such as a surrounding landscape or a milestone. The raw data photographed as described above is converted into an AVI file by the file conversion unit (conversion program) 104 (steps 200 and 202).

When the raw data is converted into an AVI file as described above, the AVI file is converted into an MPEG format of a desktop version which is programmed to be played only by a dedicated program and a web version that can be played by a general media player on the web. .

Here, the MPEG version of the desktop version is divided into a small version and a full version. When the map information and the character information are inserted into the MPEG type image data, only the dedicated driver is used on the desktop according to the execution result. A video file of type .EMPG, which is an extension of a playable form, is generated (step 204). That is, the .EMPG type video file cannot be driven by a general driving program other than a dedicated player, and the dedicated player cannot play a normal video file. It can be programmed and played on a standard Windows media player.

For example, the location data has an .ePOS extension, the map data is divided into .BMP, and the image data is divided into a .MPG form. Will be.

One moving picture data generated in .EMPG form is provided with up to five location data and map data.

Of course, the description of the photographed object can be displayed to provide text information on the description of the surrounding landscape, the description of the famous place, and the like to help the user understand. Here, the text information is displayed by accessing the corresponding text information for any 'order' data provided to the video file when the video file is read.

The following describes a method of reproducing moving picture data generated by the above method.

If the video file generated according to the above is stored in the file storage unit 106 and the corresponding driving driver (desktop player) is executed to play the video file, the predetermined video file to be played back is read (step 206). The microprocessor 102 checks a check bit provided in the video file (step 208). In the case of a video file that can be played back according to the check bit check, the microprocessor 102 reads a header part of the video file. The total playback time is retrieved (step 210, step 212).

If the playback time exists according to the search result (YES in step 212), the start code is read to initialize the bit string of the video file, and the sequence code and pack code are initialized. Next, the video bit stream is initialized (steps 214 to 224).

Of course, if there is no check bit or total playback time, or if the sequence code and pack code for initializing the moving picture bit string are not found, an error message is displayed (step 209).

When it is confirmed that the video file is playable according to the above process, playback of the video file is performed.

When playing the video file, a time event occurs every 3/1000 seconds, and the start code of the video information read for playback is read (step 226 and step 228). The conditions must be satisfied simultaneously or sequentially. That is, the combination of data related to "order number; map position; video playback position; direction" constituting a character string of the position data of the video file is examined to determine whether it can be played back. This is to prevent unauthorized distribution of the video file. As a result of the inspection of the number combination, playback is impossible when an error occurs. That is, since the map information and the text information are inserted into the video file, playback is impossible in a general driving player, and the video file can be played by a dedicated player only when the above conditions are satisfied. This is to prevent the copying and providing indiscriminately.

In other words, when the numerical combination test result sequence data processing, map position data processing, video playback position and direction data processing are normally performed (Yes in steps 230 to 236), the microprocessor 102 decodes the video file. While playing the video file, the map data is displayed via the map information output unit 108b (steps 238 and 240).

The display process of the map data reads and displays the position data and the map data for the video file, and when the new position is generated by comparing the current position with the previous position with reference to the image data authorized for a predetermined time period during the display. Moves the Mark Pointer to the new position. At this time, the character information of the video file to be reproduced matches the sequence data of the video file is read out from the text DB 112 and displayed.

On the other hand, if a mouse event related to mouse movement or mouse click on predetermined map data is generated by the user when the video and map data are displayed (step 300), the corresponding process is performed according to the event. When the mouse is positioned at a predetermined position on the mouse (Mouse over), the microprocessor 102 accesses the character DB 112 and displays a description of the current mouse position only when the mouse coordinate and the marking position are the same (step 302). To step 306), when a mouse click is generated, moving and playing the video data for the current position is performed according to whether the mouse coordinate and the display position are equal (steps 308 to 312). At this time, of course, text information about the image position to be played and the mouse cursor position on the map is provided.

However, if the mouse coordinates and the display position do not coincide with the mouse click, the map window is closed or the program is terminated or the mouse event is waited (steps 314 to 318) depending on whether the program is terminated.

Through the above process, the video information reproducing system according to the present invention displays image information, map information, and text information simultaneously on one screen, and further reproduces the image information through the image information output unit 108c. If the user clicks on a certain position in the map information output unit 108b, the corresponding video information is reproduced and output, and at the same time, the user clicks on arbitrary text data while the information is displayed through the text information output unit 108c. Then image information and corresponding location information (map) are provided. In other words, when the user clicks on any one of the image information, the map information, and the text information, the corresponding information is output through the output unit. Such a process means that mutual control is possible by a mouse operation of the screen bar, map information, and text information, as compared to controlling only moving image information by the conventional screen bar.

On the other hand, in the case of the playback system of the video information for the web version, as shown in Fig. 5b converts the video data and audio data into a video file format and then converts back to a WMV file to generate the final video file, where the map information (GIF, JPEG Format) and character information are not embedded in the video file but exist as separate data. Accordingly, when a video file is transmitted through the Internet, each video file, text, and map information are independently transmitted, thereby enabling a general player. Of course, the playback system for the web version also controls the map (location) and the text according to the screen bar and mouse operation because the image information, the map information, and the text information are driven in association with each other like the desktop version described above.

The player playing the web version of the video file uses a general WMV and ASF file format and controls map information and text information in the player. In addition, the video file for web version cannot download and modify new information from a predetermined server, whereas the above-described desktop video file is provided through a predetermined storage medium (eg, CD) and data can be modified.

As described above, according to the reproducing system of the moving picture information and the reproducing method of the present invention, since the image information, the geographic information, and the text information are simultaneously provided, realistic information can be provided.

When the user clicks on any one of the image information, the map information, and the text information, the corresponding information is output through the output unit of the user. Therefore, the screen bar and the map information and the map information are compared with the conventional screen bar. Since mutual control is possible by mouse operation of text information, information sharing can be executed accurately and easily.

In addition, the data correction method (desktop version) is easier than the conventional video player.
