Description

Subtitle Editing Device and Method for Learning

The present invention relates to a caption editing apparatus and method for learning, and more particularly, to a caption editing apparatus and method that can be used for learning by editing only the caption data in a composite data synthesized from various types of data.

Existing image reproducing apparatus is only an apparatus for reproducing and displaying the recorded data from the recording medium on which the data is recorded. However, many consumers are not satisfied with just one function in any device, but require several functions. Therefore, recently appeared devices are being implemented as a multi-system by adding various auxiliary functions in addition to the main functions of the devices.

These multi-systems are gradually becoming the most suitable form for the information society that demands simplicity and speed. For example, a digital video disc, which is an optical recording medium, may be provided as a recording medium such as various types of angle data, multiple audio data in various languages, multiple subtitle data in multiple languages, and image data for multiple titles. Stores a wide variety of data types. This can be explained by providing a wide variety of display screens to consumers, compared to existing recording media that have stored only image data for one title.

However, although the existing image reproducing apparatus can provide such various types of display screens to consumers, it can be said that it has only a reproducing function of reproducing data recorded on the recording medium. This does not meet the needs of consumers who continue to demand new and diverse functions, which in turn has become a problem that lowers the purchasing desire.

Therefore, it has been proposed that a reproducing apparatus for reproducing a digital video disc has a function other than that of reproducing the recorded data of the digital video disc. This is because digital video discs have various types of data, and can have a supplemental function using these various types of data.

Thus, the present invention proposes an image reproducing apparatus in which a learning function is added in addition to a reproducing function of reproducing data from a recording medium.

In addition, many people focus on studying listening and speaking while watching a video medium such as a movie, and the present invention intends to use it for learning by editing only desired data among complex data included in a movie.

Accordingly, the present invention is intended to edit only subtitle data among video data, audio data, and subtitle data reproduced by the video reproducing apparatus for use for learning.

Accordingly, an object of the present invention is to provide a caption editing apparatus and method for learning that can be used for learning by editing only captions in composite data.

Hereinafter, an apparatus and method for editing subtitles for learning according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating an apparatus for editing a caption for learning according to the present invention, and FIG. 2 is a flowchart illustrating an operation process of a data controller according to the present invention.

As shown in FIG. 1, the learning subtitle editing apparatus of the present invention includes a data controller 10 for controlling playback of inputted playback data and storage in a corresponding RAM, and a voice RAM for storing voice data. 20, a caption RAM 30 for storing caption data, and a display unit 40 for displaying caption data changed by the control of the data controller 10.

The data controller 10 inputs reproduction data of the digital video disc, and distinguishes between audio data and subtitle data from the reproduction data. The separated subtitle data is stored in the subtitle RAM 30, and the voice data is stored in the voice RAM 20 (step 100 of FIG. 2). That is, the data input to the data controller 10 is complex information including video data, as shown in FIG. 3A. Thus, the data controller 10 filters only the caption data from the input complex information and stores the caption data in the caption RAM 30.

The caption data stored in the caption RAM 30 is composed of caption data only, as shown in Fig. 3B. Subtitle data stored in the subtitle RAM 30 is stored by changing the value of the location information (step 110 of FIG. 2). This is because the caption data was generally located at the bottom of the screen in the state of being composited with the image data, as shown in FIG. 3A. Thus, when composed of caption data only, as shown in FIG. 3B, when the location information is not changed, “kana”, “bb” and “ABC” are located at all the same positions. You need to change the. A part of changing the value of the position information of the caption data will be described in more detail with reference to FIG. 4.

The caption data is stored in the caption RAM 30 after the position information is changed, and the voice data is stored in the sound RAM 20.

Next, the data controller 10 configures a frame as shown in FIG. 3B using only subtitle data whose value of position information is changed (step 120). In this case, the screen may be composed of only one new caption data. It is also possible to scroll as the caption data is sequentially raised on the screen. This can be changed depending on how to configure the frame when constructing the frame in the 120th step. A detailed description of the frame configuration will also be described with reference to FIG. 4.

If the screen is composed of only the caption data in step 120, the data controller 10 recognizes the voice output speed requested by the user (step 130), and the caption is configured as one screen in synchronization with the output speed of the voice data. The data is displayed on the display unit 40 (step 140). In addition, although not shown, the voice data is output through an output device such as a speaker.

That is, the present invention adds a function of separating and displaying caption data and audio data to a video reproducing apparatus whose main function is to reproduce video data, so that it can be used for learning.

Next, a process of configuring a single screen by changing the value of the caption data location information according to the present invention will be described with reference to FIG.

The data controller 10 first initializes n to " 0 " (step 224). In step 226, 1 is added to the value of n and set to n. After setting n in this way, the start position information (Xs (n)) of the X axis where the subtitle data "Kana" is located, the start position information (Ys (n)) of the Y axis, and the end position information (Ye (n)) of the Y axis And the pixel data width Yp (n) (step 200). 3A is an exemplary diagram of information read in step 200.

The data controller 10 changes the starting position information Ys (n) of the Y-axis read in step 200 to an A value. As shown in Fig. 3B, the value of A represents the value of the uppermost portion where the caption data can be located on the Y axis.

The data controller 10 changes the end position information Ye (n) of the Y-axis read in step 200 to a value obtained by adding the pixel data width Yp (n) to the value A. The X-axis starting position information of the caption data " Kana " is kept as it is unless a change in the position of the caption data on the X-axis is required (step 202).

In this way, the changed position information of "kana" as shown in FIG. 3B is calculated. Start position information (Xs (n)) of the X axis of the changed caption data "Kana", start position information (Ys (n)) of the Y axis, end position information (Ye (n)) of the Y axis, and pixel data width ( Yp (n) is stored in the subtitle RAM 30 together with the subtitle data "to go" (step 204).

Next, the data controller 10, the start position information (Xs (n + 1)) of the X axis of the next subtitle data "ㄱㄴㄷ", the start position information (Ys (n + 1)) of the Y axis, the end position information of the Y axis (Ye (n + 1)) and the pixel data width Yp (n + 1) are read (step 206).

The positional information of the subtitle data "B" is read so as to be located at the lower end of the subtitle data "Kana" as shown in FIG. 3B.

Therefore, the start position information Ys (n + 1) of the Y-axis of the caption data "ㄱㄴㄷ" read in step 206 is a value obtained by adding 1 to the end position information Ye (n) of the Y-axis of the caption data "Kanada". Change to In this way, the starting position Ys (n + 1) of the Y axis of the subtitle data "ㄱㄴㄷ" becomes one line below the subtitle data "Kana".

Then, the pixel position width Yp (n + 1) is added to the end position information Ye (n + 1) of the Y axis of the subtitle data “ㄱㄴㄷ” to the start position information Ye (n) +1 of the Y axis. The determined value is determined (step 208).

In this way, the change position information of the subtitle data "ㄱㄴㄷ" is determined, and the determined position information, Yp (n + 1), Ye (n + 1), Ys (n + 1), and Xs (n + 1) are subtitle data. It is stored in the subtitle RAM together with "ㄱㄴㄷ" (step 210).

On the other hand, the data controller 10, when changing the position information of the caption data, it is necessary to control that composed of one frame. This is because it is necessary to prevent the changed positional information of arbitrary caption data from being changed undisplayably on the screen.

Therefore, the data controller 10 changes the positional information of the caption data and accumulatively adds the pixel data width Yp (z) of the changed caption data (step 212), where z is n, n + 1. , n + 2, ...

The pixel data width? Yp (z) accumulated in step 212 is controlled so as not to exceed the scan line of the display unit 40 (step 214). That is, in the case of having 525 scanning lines, the cumulative added pixel data width ΣYp (z) is monitored not to be larger than 479 lines. In the case of having 625 scanning lines, the cumulative added pixel data width? Yp (z) is monitored not to be larger than 574 lines. The reason why the comparison value is set to the 479 lines or the 574 lines by a predetermined value is that a predetermined margin is set between the upper and lower portions of the screen and between the subtitles and the subtitles.

If the cumulatively added pixel data width ∑Yp (z) in step 214 is smaller than 479 lines (574 lines), 1 is added to the value n (step 224), and the method returns to step 206 to return the result. Repeat the process up to step 214. When the above process is repeated, the number of subtitles to be displayed on one screen is increased by one.

Next, when the cumulatively added pixel data width ∑Yp (z) in step 214 is equal to or larger than 479 lines (574 lines), the data controller 10 connects the caption data to form one frame. Terminate the process.

Then, the cumulative added pixel data width ∑Yp (z) is larger than 479 lines (574 lines), and if large, subtracts the last subtitle data included in the frame (step 218) and adds the subtitle RAM 30 to the subtitle RAM 30. The newly configured frame is displayed on the display unit 40. When the cumulatively added pixel data width? Yp (z) is equal to 479 lines (574 lines), the frame configured so far is displayed as it is (step 220).

In this way, one frame is completed, and then, the process returns to step 200 again to construct and display a new frame.

Therefore, when the positional information of the caption data is changed and output in the process shown in FIG. 4, the screen can be displayed one frame at a time and a new screen can be displayed as shown in FIG. 3B.

In addition, the description of FIG. 4 illustrates that the changed position information of the caption data is stored in the caption RAM and displayed after completion of one frame. However, according to the processing speed of the data controller 10, the source caption data may be stored in the caption RAM 30 as it is and may be controlled to be displayed at the same time as the position information is changed.

Next, FIG. 5 is a flowchart illustrating a process of changing location information of caption data according to the second embodiment of the present invention.

In FIG. 5, the change of the position information of the caption data describes a process for controlling the display of the caption data according to the scrolling method.

The data controller 10 separates the caption data from the reproduction data input during the initial operation, performs a flowchart according to the operation of FIG. 4, and changes the value of the position information of the separated caption data to edit the data in FIG. 3C. The first screen that was created. That is, the process of displaying caption data by the scroll method is performed in the same manner as in FIG. 4 until the first screen is configured.

Thereafter, after the first screen of FIG. 3c is configured, the data controller 10 initializes the value of n to 1 (step 300) to configure the second screen of 3c to be displayed next, and again to the value of n. The value of n is set by adding 1 (step 302). Then n is set to 2.

Then, the current position information values Ys (n), Ye (n), Xs (n), and Yp (n) of n = 2 subtitle data “ㄱㄴㄷ” stored in the subtitle RAM 30 while constructing the first edit screen Read it (step 304).

That is, Ys (n) is the start position information of the Y-axis of the changed caption data “ㄱㄴㄷ” when the first screen of FIG. 3C is displayed, and Ye (n) is the caption data changed when the first screen of FIG. 3C is displayed. End position information of Y axis of "ㄱㄴㄷ". Similarly, Xs (n) and Yp (n) also indicate the X-axis start position information and pixel data width of the changed caption data "ㄱㄴㄷ".

Therefore, in order to edit the second screen, the changed Y-axis starting position information Ys (n) of the subtitle data "ㄱㄴㄷ" is the previous subtitle data from the Y-axis starting position information Ys (n) read in step 304. It is set to a value obtained by subtracting the pixel data width Yp (n-1) value of "to go". This is because the subtitle data "Gana" is not displayed while scrolling on the second displayed screen, so that the amount of free space occupied by the subtitle data "Gana" is occupied. Will be moved to.

The Y-axis end position information Ye (n) of the caption data "ㄱㄴㄷ" which is newly changed for the configuration of the second screen is a pixel in the Y-axis start position information Ys (n) read in step 304. It is set to a value obtained by adding the data width Yp (n) (step 306).

In this way, the Y-axis start position information (Ys (n)), Y-axis end position information (Ye (n)), and X-axis start position information (Xs (n) of the subtitle data "ㄱㄴㄷ" to be displayed on the second screen. ) And the pixel data width Yp (n) are determined, and the changed positional information is stored in the caption RAM 30 together with the caption data " Bb " (step 308).

Next, the data controller 10 determines whether the caption data whose position information is changed in step 308 is caption data located at the bottom of the previously displayed screen (step 310).

However, the subtitle data located at the bottom of the first edited screen of FIG. 3C is "ABC". Subtitle data whose location information is changed in step 308 is "ㄱㄴㄷ", and since there was subtitle data displayed at the rear of the subtitle data "ㄱㄴㄷ" on the first edited screen, operation 310 returns to operation 302. .

Then, the data controller 10 increases the value of n by one, and position information values Ys (n), Ye (n), and Xs (n of n = 3 subtitle data “ABC” stored in the subtitle RAM 30. ), And read Yp (n) (step 304).

That is, Ys (n) is the start position information of the Y axis of the subtitle data “ABC” changed when the first screen of FIG. 3C is displayed, and Ye (n) is the subtitle changed when the first screen of FIG. 3C is displayed. End position information of the Y axis of the data "ABC". Similarly, Xs (n) and Yp (n) also indicate the X-axis start position information and pixel data width of the changed caption data "ABC".

The new Y-axis starting position information Ys (n) of "ABC" for editing the second screen is the subtitle data "ㄱㄴㄷ" from the Y-axis starting position information Ys (n) read in step 304. It is set to a value obtained by subtracting the pixel data width Yp (n-1) value of?. That is, in the second editing screen, the caption data "ABC" is moved upward on the Y axis by the pixel data width of the caption data "ㄱㄴㄷ".

The Y-axis end position information Ye (n) of the subtitle data "ABC" is added to the pixel data width Yp (n) to the Y-axis start position information Ys (n) read in step 304 above. It is set to the value made (step 306).

In this way, the Y-axis start position information (Ys (n)), Y-axis end position information (Ye (n)), and X-axis start position information (Xs (n) of the subtitle data "ABC" to be displayed on the second screen. ) And the pixel data width Yp (n) are determined, and the changed position information is stored in the caption RAM 30 together with the caption data "ABC" (step 308).

When the execution up to this point is completed, the values of the position information of all subtitle data displayed on the first edit screen have been changed. That is, the subtitle data whose position information is changed in the final step 308 is the subtitle data that was output at the bottom of the first edit screen.

Accordingly, since the subtitle data whose final position information is changed in step 308 is the last subtitle data of the previous edit screen, the data controller 10 performs a third step as a next step.

In step 312, new caption data is added to the second screen. The data controller 10 separates the caption data "Lamaba" from the composite data input from the reproduction data, and reads the positional information value of the separated caption data. At this time, the position information value of the caption data "Lamaba" to be read is the position information value determined to be located at the bottom (generally) of the screen when the caption data "Lamaba" is included with the video signal.

That is, in step 312, the position information value when the caption data "Ramaba" is separated from the image data, the start position information (Xs (n + 1)) of the X axis, and the start position information (Ys (n + 1) of the Y axis). ), The end position information (Ye (n + 1)) of the Y-axis, and the pixel data width Yp (n + 1).

The Y-axis start position information Ys (n + 1) of the caption data "Lamaba" is Y-axis end position information Ye (n) of the caption data "ABC" whose position was finally changed in step 308. Determined by adding 1 to. That is, the start position on the Y axis of the caption data "Ramabar" is a position obtained by adding 1 to the end position on the Y axis of the caption data "ABC".

In addition, the end position information (Ye (n + 1)) of the Y axis of the subtitle data "Lamaba" has the pixel data width Yp (n + 1) as the start position information Ys (n + 1) of the Y axis. It is determined by the added value (step 314).

In this way, the values of the position information of the subtitle data "Lamaba" to be displayed on the second editing screen were all changed. The changed positional information value is stored in the caption RAM 30 together with the caption data (step 316).

After performing step 316, the data controller 10 compares whether or not the end position information value Ye (n + 1) on the Y axis of the caption data finally changed in step 316 is smaller than 479 scan lines ( In step 318, if small, the value of n is increased by one (step 326), and the flow returns to step 312. Then, steps 312 to 318 are repeated.

However, when the end position information value Ye (n + 1) on the Y axis of the last changed subtitle data in step 318 is not smaller than 479 (574) scan lines, the data controller 10 completes one frame. Recognize that the process has been completed, and finish adding further subtitle data.

Then, it is determined whether the end position information value (Ye (n + 1)) on the Y axis of the finally changed subtitle data is larger than the scan line 479 (574) (step 320). The frame is constructed and displayed. However, when the end position information value (Ye (n + 1)) on the Y axis of the finally changed subtitle data is not larger than 479 (574) scan lines, the frame currently stored in the subtitle RAM 30 is displayed as it is (step 322). To step 324).

By performing the above process, the second illustrated editing screen is displayed in FIG. 3C. That is, in the second edit screen, the top caption data is removed from the first screen, and the other caption data is moved to the top step by step. At the bottom, new subtitle data was added.

When the above process is performed, the value of the changed positional information of the subtitle data for the second edit screen is stored in the subtitle RAM 30, and the data controller 10 proceeds to step 300 to construct the next third edit screen. Return By repeating the above process, the caption screen is continuously displayed in a scrolling method.

As described above, the present invention edits the screen by separating only the caption data so that the caption data can be used for learning on the video screen, and changing the position information of the separated caption data.

When the caption data is separated from the playback data in the data controller 10, the voice data is also separated and stored in the voice RAM 20, and then the voice data stored in the voice RAM 20 at the time of outputting the caption data. It is also possible to control the output. In addition, by using the output speed control function of the general video reproducing apparatus, it is possible to adjust the output speed to the user. In addition, it is also possible to control to repeatedly output the subtitles and audio stored in the voice RAM 20 and the subtitle RAM 30 by using the repetition function of the general video reproducing apparatus.

As described above, the apparatus and method for editing subtitles for learning according to the present invention further include a learning function in addition to a playback function to a general video reproducing apparatus. Therefore, it can be used more efficiently during language learning using the image reproducing apparatus, and also has the effect of increasing the purchase desire of the product by the addition of the auxiliary function.
