Abstract

Disclosed is a method to eliminate a character caption, utilizing on-screen display. The method comprises an initialization routine(L1) and an on-screen display character output routine(L2). In the initialization routine(L1), a pointer is set to an initial point when an on-screen display shadow key is inputted, and when a microcomputer has discriminated location of the character caption whether on a vertical location or a horizontal location. In the on-screen display character output routine(L2), an initial and end locations are selected and stored according to a point key, and the on-screen display characters between the stored locations are displayed. Thereby, the on-screen display characters can be displayed on the character caption, so that the user's utilization can be improved.

The present invention relates to a video tape recorder (hereinafter referred to as a video), and more particularly, to study language by screening a text caption from a video tape on an on screen display (OSD) text. The present invention relates to a method of removing text subtitles using OSD to increase the concentration of poetry learning.

Generally, students or office workers watch movie tapes for listening training. Most of the existing movie tapes for rental are recorded with subtitles (Korean subtitles or subtitles of other languages). There was an inconvenience in seeing the subtitles with a piece of paper and watching. In addition, when the caption character is viewed in the caption video, a general character subtitle (eg, a Korean subtitle) is partially visible on the back of the caption character, thereby visually confusing the viewer, thereby lowering the concentration of learning.

The present invention is to solve this problem, an object of the present invention is to provide a method for removing subtitles using the OSD to increase the concentration of learning by covering the subtitles from the general movie tape with OSD characters. have.

Another object of the present invention is to provide a method of removing a subtitle using an OSD which displays a caption character in a state in which the subtitle is covered by the OSD character.

In order to achieve the above object, the present invention provides a key input unit for inputting an OSD shadow key or the like to hide text subtitles, a microcomputer connected to the key input unit, and outputting a control signal according to a signal input from the key input unit; An OSD processing unit connected to the micom to receive a stove, data, and a clock signal from the micom to process an OSD character; and an OSD processing unit connected to the micom to receive a strobe, data, and clock signal from the micom to process a caption character; A video caption display method having a caption processing unit and a video output unit connected to the OSD processing unit and the caption processing unit for synthesizing and outputting OSD characters, caption characters, and video signals, the OSD shadow key being input from the key input unit and inputted to the microcomputer. By the subtitles in the horizontal or vertical position An OSD consisting of an initialization routine that sets a pointer to the initial position when it is determined, and an OSD character output routine that selects and stores a start position and an end position using a point key, and displays it as an OSD character inputted to a stored start position and end position. Text subtitle removal method using

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a character subtitle removing device according to the present invention, comprising a key matrix and a remote controller and the like for inputting an OSD shadow key and a point key, and connected to the key input unit 10. The microcomputer 1 outputs a control signal according to the input key signal and the microcomputer 10 receives the strobe, data, and clock signals from the microcomputer 10. An OSD processing unit 20 for outputting an OSD character and a caption connected to the microcomputer 10 to receive a strobe, data, and clock signal from the microcomputer 10 to output a caption character. The video output unit 40 is connected to the processing unit 30, the OSD processing unit 20 and the caption processing unit 30, and synthesizes the OSD text, caption text, and video signals and outputs them to the CRT.

2 is a flowchart showing an embodiment of a method for removing a text caption according to the present invention, which includes an initialization routine L1 and an OSD text output routine L2.

Here, the initialization routine (L1), the step (S1) for determining whether the OSD shadow key is input from the key input unit 10, and performs the corresponding key operation if the OSD shadow key is not, and outputs to the screen if the OSD shadow key (S2, S3) for determining whether the displayed character subtitle is positioned horizontally or vertically; step (S4) for setting the pointer so that the pointer appears at the vertical initial position if the vertical position; Step S5 of setting the pointer so that the pointer appears is made.

In addition, the OSD character output routine L2 starts the step S6 of selecting a start position by moving a point key when a pointer is set at a corresponding position in the initialization routine L1, and starting with a point storage key when a start position is selected. Step S7 for storing the position, step S8 for moving the pointer key to select the end position and storing with the point storage key, and when the start position and the end position are selected, the OSD characters simultaneously inputted are the start position and the end position. Step S9 is output to the screen according to the position.

FIG. 3 is an actual example of performing the method of removing characters of FIG. 2, (a) shows that a subtitle of a character is displayed in a horizontal position and a pointer appears, and (b) shows a start position and an end with a point key and a point storage key. Setting and saving the position and showing the OSD characters displayed, (c) shows the caption characters displayed over the displayed OSD characters.

According to the present invention configured as described above, when the OSD shadow key is input through the key input unit 10 in step S1, the OSD shadow mode is entered, and in step S3, the subtitle displayed by the microcomputer 1 is vertically displayed. Or determine if it is displayed horizontally.

If it is vertical, the pointer appears while the pointer is set at the vertical initial position in step S4, and if it is horizontal, the pointer appears while the pointer is set at the horizontal initial position at step S5.

At this time, if the OSD shadow key is input to hide the subtitles displayed horizontally as shown in FIG. 3A, the steps S3 and S5 are performed to display a pointer, and the point key is moved to the starting position in step S6. After selecting, save the selected starting position by using the point storage key in step S7.

Then, when the end position is selected and stored again in step S8 using the point key and the point storage key, step S9 is performed simultaneously so that the previously entered OSD characters are moved from the start position to the end position in FIG. As shown in b), the subtitle is hidden.

At this time, the displayed OSD character can be selected by the user.

Meanwhile, when watching a video tape having a caption function, the caption text can be viewed while the text caption is covered by executing the above-described OSD shadow function.

As described above, the present invention improves the efficiency of listening when studying language by screening text subtitles from general video tapes with OSD characters, and in particular, by displaying caption characters on OSD characters in a video with caption function. Subtitles) are invisible, and only the caption characters (English characters) are shown, which increases the concentration of learning.
