Mutual translation output method for dual subtitles of caption broadcasting receiver

The present invention relates to a method for translating and translating dual subtitles of a caption broadcasting receiver, and more particularly, to a caption signal for dual subtitles input from a recording / playback apparatus, storing a first language and a second language separately in a memory. The present invention relates to a mutual translation output method for a dual subtitle of a caption broadcasting receiver for translating and outputting a selected sentence to a second language (first language) for a displayed first language (second language).

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 document data, and the text 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.

Here, 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 as 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 is scrolled upward in the second screen area.

However, the recording and reproducing apparatus having the caption function described above simply divides the video display screen into two to display the characters of the image and the caption signal, respectively, and sets the 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 desired section.

Accordingly, an object of the present invention is to display the first language (second language) displayed after storing the first language and the second language separately in a memory in case of a caption signal for the dual subtitle input from the recording / reproducing apparatus so as to solve the above problems. The present invention provides a method for translating and translating dual subtitles of a caption broadcasting receiver to translate and output a sentence selected by a user into a second language (first language).
