Abstract

본 발명은 텔레비전방송신호에 포함되어 전송되는 자막신호의 전송여부에 따른 정보를 제공하는 코드데이터를 검출하고 있는 상태에서 OSD표시를 위한 기능조작이 행해지게 되면 해당 OSD표시정보가 자막이 표시되는 화면영역 이외의 화면영역에서 표시될 수 있도록 하는 텔레비전의 자막표시에 의한 OSD문자 위치 변경제어장치를 제공한다.According to the present invention, when a function operation for OSD display is performed while detecting code data for providing information according to whether or not a subtitle signal transmitted by being included in a television broadcasting signal is transmitted, a screen displaying corresponding subtitle display information is displayed. Provided is an OSD character position change control apparatus by subtitle display of a television which can be displayed in a screen region other than the region.

그에 따라 본 발명은 영상증폭부(2)로 부터의 휘도신호를 인가받아 동기 분리부(8)에서 분리된 수직동기신호(Vsync)와 수평동기신호(Hsync)에 의거하여 신호처리함에 의해 자막신호를 추출하는 자막신호처리수단(18)을 갖춘 텔레비전에 있어서; 상기 동기분리부(8)로 부터 자막신호의 전송여부에 대한 정보를 갖춘 코드데이터를 검출하는 코드신호검출수단(10,12)과, OSD표시정보에 의한 조정기능이 가능한 기능동작을 키설정하는 기능설정수단(14), 상기 코드신호검출수단(10,12)에 의해 코드데이터가 검출되고 상기 자막신호처리수단(18)에 의해 자막이 화면표시되는 상태에서 상기 기능설정수단(14)의 OSD표시정보에 의한 조정기능이 가능한 기능동작의 키설정에 따라 해당 기능동작에 대한 OSD표시정보가 상기 자막의 화면표시영역 이외의 화면영역에서 표시되도록 제어하는 제어수단(16), 상기 제어수단(16)의 제어하에 상기 기능동작에 따른 OSD표시정보를 생성하는 OSD신호처리수단(20) 및, 상기 제어수단(16)에 의해 제어되어 상기 생성된 OSD표시정보의 화면표시위치를 변경하여 지정하는 OSD위치변경수단(22)를 구비하여 구성된 것을 특징으로 한다.Accordingly, the present invention receives the luminance signal from the image amplifier 2 and processes the subtitle signal by processing the signal based on the vertical sync signal Vsync and the horizontal sync signal Hsync separated by the sync separator 8. A television comprising a caption signal processing means (18) for extracting a? Code signal detecting means (10, 12) for detecting code data having information on whether or not the caption signal is transmitted from the synchronizing separator (8), and for setting a function operation capable of adjustment function by OSD display information. OSD of the function setting means 14 in a state in which code data is detected by the function setting means 14 and the code signal detecting means 10 and 12 and the subtitles are displayed on the screen by the subtitle signal processing means 18. Control means (16) and control means (16) for controlling OSD display information for the function operation to be displayed in a screen area other than the screen display area of the subtitle according to the key setting of the function operation capable of adjustment function based on the display information. OSD signal processing means 20 for generating OSD display information according to the function operation, and OSD controlled by the control means 16 to change the screen display position of the generated OSD display information. Change location Provided with a stage (22) is characterized in that configured.

Claims

A caption signal for extracting a caption signal by receiving a luminance signal from the image amplifier 2 and processing the signal based on the vertical sync signal Vsync and the horizontal sync signal Hsync separated by the sync separator 8. In a television equipped with a processing means (18), code signal detecting means (10, 12) for detecting code data having information on whether or not to transmit a caption signal from the sync separating section (8) and OSD display information. The code data is detected by the function setting means 14 and the code signal detection means 10 and 12 for key setting a function operation capable of an adjustment function by the control function, and the subtitle is displayed on the screen by the subtitle signal processing means 18. In accordance with the key setting of the function operation capable of the adjustment function by the OSD display information of the function setting means 14, the OSD display information for the function operation is displayed on the screen area other than the screen display area 36 of the subtitle. ) To control the display The OSD 16, the OSD signal processing means 20 for generating OSD display information according to the function operation under the control of the control means 16, and the generated OSD display controlled by the control means 16; And an OSD position changing means (22) for changing and specifying a screen display position of information.

2. The function operation according to claim 1, wherein the function operation capable of the adjustment function by the OSD display information keyed by the function setting means 14 is applied to the volume adjustment function of the audio signal, the contrast adjustment function of the video signal, and the brightness adjustment function. OSD character position control by the caption display of the television, characterized in that corresponding to the analog level adjustment function.
