Abstract

PURPOSE: A method for processing a caption of a digital TV is provided to automatically activate a subtitle function in the case of selecting a mute-off, thereby grasping contents of a program through a subtitle in a mute-off state of a digital TV. CONSTITUTION: A digital TV receives a mute command of a user(1). The digital TV confirms the current mute state(2). If the current state is a mute-off state, the digital TV confirms whether a subtitle flag is selected(3). If so, sound is on(4). If not, a subtitle is off and the sound is on(5). If the current state is not the mute-off state, the digital TV confirms whether the subtitle flag is selected(6). If so, the sound is off(7). If not, the subtitle is on and the sound is off(8).

Description

디지털 티브이의 캡션 처리 방법 { Method for processing captions of digital television }Caption processing method for digital TV {Method for processing captions of digital television}

본 발명은 캡션 처리 방법에 관한 것으로, 특히 디지탈 TV의 캡션 처리 방법에 관한것이다. 디지탈 TV는 현재의 아날로그 TV를 대체하는 새로운 TV로서 현재 시장에서 차츰 그 영역을 확대하고 있다. 디지탈 TV는 아날로그 TV와는 달리 방송사에서 일반적인 영상이나 혹은 오디오 신호외에 다양한 종류의 정보를 문자로 제공할 수 있는 기능도 가지고 있다. 예를 들면, 사용자가 시청하는 드라마의 인물에 관한 정보라든지,혹은 드라마의 대본등 다양한 정보를 제공할 수 있는 것이다. 현재의 디지탈 TV에서의 캡션 처리 방법은 일반적으로 사용자가 캡션 기능을 선택하면 오디오 정보가 자막처리되어 TV의 화면에 캡션 처리되어 나타나게 된다. 이러한 기능은 외국어 학습이나 혹은 청각장애자들에게 있어서 유용하게 정보를 수신할 수 있는 장치가 될 것이다. 그러나,이러한 캡션정보가 상술한 바와 같이 활용되는 대신에 좀 더 범위를 확장시킨다면 사용자에게 편리함을 한층 더 가져다 줄 수 있을 것이다. 현재의 TV 기능에서 음소거 기능을 예로 들면,사용자는 TV 시청시 전화를 받는다거나 혹은 주위의 다른 사람에 관계없이 혼자서 TV를 시청하고 싶을 때 음소거 기능을 선택하는 경우가 많다. 그러나,이러한 음소거 기능을 선택할 때 사용자는 오디오 정보를 듣지 못하게 되는 불편함이 존재할 수 있다.The present invention relates to a caption processing method, and more particularly, to a caption processing method of a digital TV. Digital TV is a new TV that replaces current analog TV and is gradually expanding its scope in the market. Digital TVs, unlike analog TVs, also have the ability for broadcasters to provide text and other types of information in addition to the usual video or audio signals. For example, the user may provide various information such as information about the person of the drama or the script of the drama. In the current digital TV caption processing method, when a user selects a caption function, audio information is closed captioned and displayed on the screen of the TV. Such a function would be a device for receiving information usefully for foreign language learning or hearing impaired people. However, if such caption information is expanded as a range instead of being utilized as described above, it may bring more convenience to the user. Taking the mute function as an example of the current TV function, the user often selects the mute function when answering a call when watching TV or when he / she wants to watch TV by himself regardless of other people around him. However, there may be inconvenience that the user may not hear audio information when selecting such a mute function.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로써, 디지탈 TV의 음이 소거 상태에서도 사용자에게 음성에 상당하는 정보를 문자 자막으로 알려주는 방법을 제공하여 보다 편리한 TV시청을 가능하게 하고 중요한 정보를 놓치는 일이 없도록 하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and provides a method of notifying the user with information corresponding to the voice as text subtitles even when the sound of the digital TV is muted to enable more convenient TV viewing and important. The goal is to make sure you don't miss the information.

도1 : 사용자의 음소거 명령에 따른 디지털 TV의 캡션 처리 방법의 순서도1 is a flowchart of a caption processing method of a digital TV according to a user's mute command

상기의 과제를 해결하기 위한 본 발명에 따른 디지털 TV의 캡션 처리 방법의 특징은 사용자가 음소거 기능을 선택하는 단계와, 상기 방송정보가 자동적으로 자막화 되어 디지탈 TV의 일정영역에 디스플레이되는 단계를 포함하여 구성됨에 있다.Features of the caption processing method of the digital TV according to the present invention for solving the above problems include the step of the user selecting a mute function, and the broadcasting information is automatically subtitled and displayed in a certain region of the digital TV It is composed.

본 발명의 다른 목적, 특징, 이점들은 첨부한 도면을 참조한 실시 예들의 상세한 설명을 통해 명백해 질 것이며 이하 도면을 살펴보기로 한다Other objects, features, and advantages of the present invention will become apparent from the following detailed description of embodiments taken in conjunction with the accompanying drawings.

도1은 음소거 명령에 따른 디지털 TV의 캡션 처리 방법의 순서도이며, 사용자의 음소거 명령을 입력 받아 다음과 같이 동작한다.1 is a flowchart of a caption processing method of a digital TV according to a mute command, and receives a mute command of a user and operates as follows.

1번. 사용자의 음소거(Mute command)를 입력 받는다.number 1. Receive the mute command of the user.

2번. 현재 Mute상태를 확인하여 Mute On이면 3번, Off상태이면 6번 동작을 한다.No.2. Check the current Mute status and operate 3 times if Mute On and 6 times if Off.

3번. 음소거 상태이면 자막 선택(Subtitle flag) 중인지 확인하여 On이면 4번, Off상태이면 5번 동작을 한다.number 3. If it is muted, check whether the subtitle flag is in progress and operate it 4 times if it is On and 5 times if it is Off.

4번. 자막 기능 선택 중이면 소리를 복구(Sound On)한다.4 times. If the subtitle function is selected, the sound is restored (Sound On).

5번. 자막 기능 선택되지 않았으면 자막을 비활성화(Subtitle Off)하고 소리를 복구(Sound On)한다.5 times. Subtitle function If not selected, subtitles off and restores sound.

6번. 음소거 상태가 아니면 자막 선택(Subtitle flag) 중인지 확인하여 On이면 7번, Off상태이면 8번 동작을 한다.6 times. If it is not muted, check whether the subtitle flag is in progress and operate 7 times if it is On and 8 times if it is Off.

7번. 자막 기능 선택 중이면 소리를 소거(Sound Off)한다.7 times. If the subtitle function is selected, the sound is muted.

8번. 자막 기능 선택되지 않았으면 자막을 활성화(Subtitle On)하고 소리를 소거(Sound Off)한다.8 times. Subtitle function If not selected, the subtitle is activated and the sound is turned off.

즉, Mute Cmmand가 있을 시, Mute On/Off 여부를 판단(2)하고 그 각각의 경우에 대해 Subtitle Falg이 선택되어 있는지 여부를 판단(3 과 6)하는 것을 포함하여 4가지의 경우가 발생하는 것이다.That is, when there are Mute Cmmands, four cases occur including determining whether to mute on / off (2) and whether or not Subtitle Falg is selected for each case (3 and 6). will be.
