[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail based on one illustrated embodiment. In the video reproduction method of the present invention, character information displayed together with video information on the screen is managed and controlled separately from the video information.
[0023]
Specifically, the character information displayed together with the video information on the screen is classified for each predetermined item separately from the video information. The information classified into each item is further hierarchized for each related information. These are formed and managed as one unit by a tree structure. For example, as shown in FIG. 1, first, character information is classified for each scene. In each scene, information related to a person appearing in the scene is classified for each character. Further, the dialogue of each character is classified into a sentence unit or a unit with a better division (for example, a word). These are formed and managed as one unit by a tree structure.
[0024]
In the present invention, since the character information related to the video information is managed separately from the video information, when displayed at the same time as the video information, each scene unit, each character unit, and further, each appearance It can be managed and controlled on a line-by-line basis and displayed on the screen. Also, by simultaneously reading out information classified for each item, it is possible to simultaneously display a plurality of pieces of information on the same screen. Therefore, for example, when the video reproducing method of the present invention is used for learning a foreign language, a plurality of types of languages can be simultaneously displayed on the same screen.
[0025]
In the present invention, the character information is stored in a multimedia content description interface MPEG-7 format. MPEG-7 is one of the XML formats, and it is easy to search for another example using the same word, and to call a dictionary tool.
[0026]
Next, a processing procedure of the video reproducing method of the present invention will be described. FIG. 2 is a flowchart showing a procedure for executing the video reproducing method. It is assumed that video information and character information displayed on a screen by the video reproduction method of the present invention are stored in a storage medium in advance.
[0027]
1) First, all character information is extracted from the storage medium (step S1).
[0028]
2) Analyze the character information extracted in step S1 and display characters on the screen (for example, all information relating to a specific scene, all information relating to a specific character, or only information relating to a specific dialogue, etc.) Is selected (step S2).
[0029]
3) The position of the character information to be displayed on the screen is determined (step S3). In the present invention, instead of embedding the character information in advance in the video information, the character information is formed in a tree structure as shown in FIG. The display method can be arbitrarily selected. Therefore, in the present invention, character information can be displayed as captions overlaid on the video information displayed on the screen as shown in FIG. 3A, or the video information can be displayed as shown in FIG. It is also possible to display only character information on a screen different from the displayed screen. In addition, the size of displayed characters and the color of displayed characters can be set for each speaker. These settings are made in advance by the user.
[0030]
4) Extract video information to be displayed on the screen from the storage medium (step S4).
[0031]
5) The character information selected in step S2 is displayed on the screen in synchronization with the video information extracted in step S4. At this time, the character information is displayed at the position on the screen determined in step S3 (step S5).
[0032]
6) Check whether there is an instruction from the user (step S6). The instruction from the user is executed by operating a remote controller (or operation panel) 10 as shown in FIG. The remote control 10 is provided with a play button 11, a fast forward / rewind button 12, a cue button (front / rear) 13, a repeat button 14, a stop button 15, and the like. A desired operation can be performed. If there is no instruction from the user (Step S6: No), the process returns to Step S2, and proceeds to the process of processing the character information of the next scene. If an instruction from the user has been received (step S6: Yes), the process proceeds to step S7.
[0033]
7) The video is reproduced based on the instruction from the user in step S6 (step S7). For example, when the instruction from the user is a repetitive reproduction of the same video (that is, the repeat button 14 of the remote controller 10 shown in FIG. 4 has been operated), the scene reproduced immediately before the release is canceled until the release. Will be played again from the first part of. Then, when the repetition mode is set, the scene reproduced immediately before is automatically repetitively reproduced unless it is released. If the instruction from the user is to change the video to be reproduced (that is, the cue button 13 of the remote controller 10 shown in FIG. 4 has been operated), the reproduction is started from the head of the designated item unit. You.
[0034]
For example, if the cue button (previous) 13 is pressed once during the reproduction of the dialogue sentence 1 of the character B of the scene 1 shown in FIG. Is reproduced from the beginning. Similarly, when the button is pressed twice, the item immediately before the item currently being reproduced (the dialogue sentence 3 of the character A in the scene 1) is reproduced from the beginning. Further, according to the present invention, since the character information can be managed and controlled in fine units as shown in FIG. 1, the head of a specific scene, the head of a specific character, or the head of a specific dialog, etc. Reproduction from the beginning in various item units becomes possible.
[0035]
As described above, according to the video reproduction method of the present invention, instead of embedding characters in a video, by managing the text information separately from the video information, the display area of the text information and the display method thereof can be changed. It can be set arbitrarily. Further, by simultaneously reading out information classified for each item, it is possible to simultaneously display a plurality of pieces of information on the same screen. Therefore, for example, when the video reproducing method of the present invention is used for learning a foreign language, a plurality of types of languages can be simultaneously displayed on the same screen, or only one language information can be displayed. For this reason, by displaying two languages at the same time, the utterance content of the foreign language and the meaning in the native language can be grasped at the same time. By turning off the word display, it is possible to confirm the degree of understanding only by voice.
[0036]
In addition, according to the video reproducing method of the present invention, since character information is classified and managed and controlled in small item units, heading can be performed in each item unit. It can be repeated immediately and can be checked any number of times. Further, since the information classified into the items is further subdivided and managed in a hierarchical manner, by switching the unit of the displayed item, the information can be displayed in various item units. Further, once the repetition mode is set, the previously reproduced scene is automatically repetitively reproduced unless it is released, so that the same scene can be repeatedly viewed until the user is satisfied. In addition, since the character information displayed on the screen can be searched for in finely categorized item units, a specific scene can be reproduced and confirmed any number of times.
[0037]
The video reproducing method described in the present embodiment can be realized by executing a prepared program on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed by being read from the recording medium by the computer. The program may be a transmission medium that can be distributed via a network such as the Internet.
[0038]
The embodiment of the present invention has been described with reference to the drawings. However, the present invention is not limited to the matters described in this embodiment, and modifications, improvements, and the like can be made based on the description in the claims.
[0039]
【The invention's effect】
As described above, according to the video reproduction method of the present invention, the display area of the text information and the display method can be set arbitrarily by managing the text information separately from the video information. Further, by simultaneously reading out information classified for each unit, it is possible to simultaneously display a plurality of pieces of information on the same screen. Therefore, for example, two languages can be simultaneously displayed as captions. Further, it is possible to reproduce and confirm a specific sentence or word repeatedly and accurately in as small a unit as possible.
