DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 3 is a block diagram showing a character subtitle removing apparatus according to the present invention. A key matrix for inputting an OSD shadow key and a point key and a key input section 10 composed of a remote controller and the key input section 10 are provided. A microcomputer 6 that is connected and outputs a control signal in response to an input key signal; and the microcomputer 6 that is connected to the microcomputer 6
The strobe, the data, and the clock signal from the microcomputer 6 are connected to the OSD processing unit 20 that outputs an OSD character, and the microcomputer 6 is connected to the strobe,
A caption processing unit 40 that outputs a caption character by providing data and a clock signal, and is connected to the OSD processing unit 20 and the caption processing unit 40 to synthesize an OSD character, a caption character, and a video signal and output the combined result to a cathode ray tube. And a video signal output unit 30.

FIG. 4 is a flow chart showing an embodiment of the character caption removal method according to this embodiment.
It is composed of an SD character output routine R2. It should be noted that this processing is stored in a ROM (not shown) in the microcomputer 6.

Here, the initialization routine R1 performs step S1 of determining whether the OSD shadow key is input from the key input unit 10 and the corresponding key operation if the OSD shadow key is not selected, and the OSD shadow key is operated. If it is a shadow key, steps S2 and S3 for determining whether the character subtitle output on the screen is positioned horizontally or vertically, and if it is a vertical position, the pointer is moved to the vertical initial position. Step S4 of setting the pointer so as to appear and step S5 of setting the pointer so as to appear at the horizontal initial position when the position is the horizontal position are provided.

Then, the OSD character output routine R2
In the initialization routine R1, when the pointer is set at the corresponding position, the point key is moved to select the starting point position, step S6; and when the starting point position is selected, the point storing key stores the starting point position. Step S
7, step S8 of moving the point key to select the end point position and storing with the point storage key. When the start point position and the end point position are selected, the input OSD character matches the start position and the end position. Thus, the step S9 for outputting on the screen is provided.

FIGS. 5 to 7 show an actual implementation example of performing the character removing method of FIG. 4, and FIG. 5 shows that the character subtitles are displayed in the horizontal position and the pointer is displayed. FIG. 6 shows that the start point position and the end point position are set and stored by the point key and the point storage key, and the OSD character is displayed, and FIG. 7 shows the caption character displayed on the displayed OSD character. It is shown that.

In the above configuration, when the OSD shadow key is input through the key input unit 10 in step S1,
The OSD shadow mode is entered, and it is determined in step S3 whether the character subtitles displayed by the microcomputer 6 are displayed vertically or 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 is displayed with the pointer set at the horizontal initial position in step S5. It

At this time, if the OSD shadow key is input to block the horizontally displayed character subtitles as shown in FIG. 5, steps S3 and S5 are performed to display the pointer, and the point key is pressed in step S6. Is moved to select the start position, and the start point position selected by the point storage key is stored in step S7.

Then, the end point position is selected and stored again in step S8 using the point key and the point storage key. Then, when the process proceeds to step S9, the OSD characters input in advance are displayed from the start point position to the end point position as shown in FIG. 6 to block the character subtitles. The OSD characters displayed can be arbitrarily selected by the user.

On the other hand, when auditioning a video tape having a caption function, the caption characters can be seen in a state where the character subtitles are interrupted as shown in FIG. 7 by executing the OSD shadow function. .

In the embodiment, the starting point and the ending point for displaying the fixed OSD character are, for example, when the subtitles are displayed in the horizontal direction, the position where the subtitles are displayed from the bottom of the screen. Since the width is almost fixed, the width is simply determined, but it goes without saying that two points on the diagonal of the rectangle may be set.
