Abstract

The method of changing the basic color of the disclosed caption broadcasting receiver is to change the background color and the text color to the user's favorite color when the caption signal is displayed as white text on the black background which is the basic color on the display means.

According to the present invention, when there is a caption signal input from the recording / reproducing apparatus, it is determined whether or not there is a key signal for memory storage, and as a result of the determination, it is determined whether a key signal for caption mode selection has been input. As a result of the determination, if there is a key signal for caption mode selection, the video signal superimposed with the text signal is displayed and stored in the memory.When the display is finished, the caption signal is displayed by selecting a file stored in the memory and displaying the desired background color. And a background signal and a text color of the displayed caption signal are displayed by using the application program provided by the control unit when the key signal for changing to the text color is input.

Accordingly, the present invention is to provide an effect that can maximize the learning effect and the satisfaction of the needs by changing the background color and the text color to the color that the user always prefers the background color and the text color displayed the same.

Description

How to change the basic color of the caption broadcast receiver

The present invention relates to a method for changing a basic color of a caption broadcasting receiver, and more particularly, when a caption signal is displayed as a white text on a black background, which is a basic color, on a display means. The present invention relates to a method of changing a basic color of a caption broadcasting receiver which can be changed.

In general, the closed captioning method in television broadcasting includes an open caption method that superimposes a caption signal in an active section of the television signal, thereby displaying urgent news or notifications by the broadcaster's selection without the viewer's selection, and the non-caption of the television signal. When a caption signal is transmitted in an active section, that is, in a vertical blanking section, there is a closed captioning method in which a television screen and dialogue contents can be viewed as captions by a viewer's selection.

Closed captioning closed captioning has been in operation in the United States since 1978 for people with hearing disabilities without sign language.

The closed caption function described above inserts a predetermined caption signal at a predetermined position of the video signal, for example, at the 21st horizontal line, and stores it in the recording medium.

When the recording medium storing the caption signal is reproduced as described above, the caption signal is detected from the reproduction signal and decoded into the character data, and the character signal corresponding to the character data is generated to be reproduced on the screen of a video display device such as a television receiver. It is displayed together with the video signal.

In addition, the closed caption function described above displays characters different from the audio signal output to the speaker.

For example, a speaker outputs an audio signal in Korean, and displays English characters on the screen.

Caption signal reproduction devices having such caption functions are repeatedly used by the user for learning a foreign language.

1 is a schematic block diagram of a recording and reproducing apparatus having a caption function for implementing caption signals recorded on a recording medium according to the prior art for language learning.

As shown in the drawing, the control unit 11 controls the reproduction and repetitive reproduction of the caption signal, and an operation command for operating a user's key signal input or a remote control transmitter (not shown) to the control unit 11. An operation command input unit 12 for inputting, a deck 13 for reproducing the recorded signal while driving the recording medium 14 under the control of the control unit 11, and a recording medium 14 for the deck 13 to travel. The travel counter 15 for counting the travel value of the < RTI ID = 0.0 >), the data slicer 16 for detecting the caption signal inserted into the video signal reproduced from the recording medium 14, and the caption signal detected by the data slicer 16. A caption decoder 17 for decoding the character data, a count value of the traveling counter 15 and a memory 18 for storing and outputting the character data output from the caption decoder 17, and the character data stored in the memory 18. A statement that generates a text signal corresponding to The generator 19 and the mixer 20 for mixing and outputting a text signal output from the loss character generator 19 to the video reproduced on the recording medium 14 under the control of the controller 11. .

In the prior art configured as described above, when the operation command input unit 12 inputs a playback command to the control unit 11 according to a user's key input, the control unit 11 controls the deck 13 to reproduce the recording medium 14. The travel counter 15 counts and outputs the travel value of the recording medium 14.

The image reproduced on the recording medium 14 is input to the mixer 20 and to the data slicer 16.

Then, the data slicer 16 detects the caption signal inserted at the predetermined position of the reproduced video signal, and the caption decoder 17 decodes the detected caption signal to output the character data according to the caption signal.

The character data output by the caption decoder 17 and the running count value of the recording medium 14 output by the traveling counter 15 are input to the memory 18 and stored together.

Herein, the capacity of the memory 18 is set to such a degree that the character data that can be displayed on one screen and the value of the driving count according to the character data can be stored, and stored and erased first in first out. do.

In accordance with the character data stored in the memory 18, the character generator 19 generates a character signal, and the generated character signal is input to the mixer 20.

The mixer 20 mixes and outputs the character signal output by the character generator 19 to the image reproduced by the recording medium 14 under the control of the controller 11.

At this time, the memory 18 stores and erases the character data in a first-in, first-out manner so that the character scrolls upward in the lower region of the screen.

However, the recording and reproducing apparatus having the above-described caption function simply displays a video signal at the top of the screen, a text signal at the bottom of the screen, and sets a repetitive playback section using the position at which the characters displayed on the screen are reproduced. There was a problem in that the user could not arbitrarily give various functions to the caption signal only by repeatedly repeating the section correctly.

Accordingly, an object of the present invention is to receive a caption broadcast to change the background color and text color to the user's favorite color when the caption signal is displayed as a white text on a black background which is a basic color on the display means so as to solve the above problems. It provides a method of changing the basic color of the device.
