Abstract

본 발명은 자막위치정보를 이용한 자막신호 위치 조정장치 및 방법에 관한 것으로, 종래에는 화면에 디스플레이되는 자막위치에 관한 정보를 알수 없어 자막의 위치를 정확하게 조정하지 못하는 결점을 가지고 있었다. 본 발명은 입력 영상신호(Vin)에서 수직/수평 동기신호(V.sync/H.sync)를 분리하는 수직/수평 동기신호 분리부와, 상기 수직/수평 동기신호 분리부에서 출력되는 수직 동기신호(V.sync)와 자막위치정보 검출부로부터 공급되는 자막위치정보를 논리합한 후 이를 발전하는 노아 게이트롸, 상기 노아 게이트의 출력에 의해 리세트 되어 상기 수직/수평 동기신호 분리부에서 공급되는 수평동기신호(H.SYNC)를 카운팅하여 자막신호의 시작/끝 지점의 수평라인에 대한 카운팅값을 출력하는 카운터와, 상기 카운터에 출력되는 카운팅값을 인가받아 자막 신호가 디스플레이되는 수평라인 구간을 연산하는 자막위치 판별부와, 상기 자막위치 판별부의 연산결과에 의해 화면의 수직 센터를 조정하는 수직센터 이동부를 포함하는 자막위치정보를 이용한 자막신호 위치 조정장치를 구성함으로써 화면에 디스플레이되는 자막신호의 위치를 자동으로 조정할 수 있는 것이다.The present invention relates to an apparatus and method for adjusting caption signal position using caption position information. In the related art, information on caption position displayed on a screen cannot be known. The present invention provides a vertical / horizontal sync signal separator for separating the vertical / horizontal sync signal (V.sync / H.sync) from an input image signal Vin, and a vertical sync signal output from the vertical / horizontal sync signal separator. (V.sync) and a horizontal synchronization supplied from the vertical / horizontal synchronization signal separation unit which is reset by the output of the Noah gate and the output of the Noah gate after logically combining the subtitle position information supplied from the subtitle position information detection unit. A counter for counting a signal (H.SYNC) and outputting a counting value for the horizontal line at the start / end point of the caption signal, and calculating a horizontal line section in which the caption signal is displayed by receiving a counting value output to the counter. Caption signal position adjustment using caption position information including a caption position determination unit and a vertical center moving unit for adjusting the vertical center of the screen according to the calculation result of the caption position determination unit. By configuring the value that will automatically adjust the position of the caption signal to be displayed on the screen.

Claims

A vertical / horizontal synchronization signal separator for separating the vertical / horizontal synchronization signal V.sync / H.sync from the input image signal Vin; A noah gate for generating a logical synchronism between the vertical sync signal (V.sync) output from the vertical / horizontal sync signal separator and the caption position information supplied from the caption position information detector; A counter for counting the horizontal sync signal H.SYNC, which is reset by the output of the NOR gate and supplied from the vertical / horizontal sync signal separator, and outputs a counting value for the horizontal line at the start / end point of the caption signal. ; A caption position discriminating unit configured to calculate a horizontal line section in which a caption signal is displayed by receiving a counting value output from the counter; Caption signal position adjusting apparatus using the caption position information, characterized in that it comprises a vertical center moving unit for adjusting the vertical center of the screen according to the calculation result of the caption position determining unit.

Checking the input state of the vertical synchronization signal V.sync while separating the vertical / horizontal synchronization signal V.sync / H.sync from the input image signal Vin; When the vertical synchronizing signal (V.sync) is input, the horizontal synchronizing signal (H.sync) is counted and the counting operation of the horizontal synchronizing signal (H.sync) is performed while outputting the corresponding count value at the start point where the subtitle signal is displayed. Continuing; Checking the caption position information input state of the end point where the caption signal is displayed while counting the horizontal sync signal H.sync and outputting a counting value of the end point when the horizontal sync signal H.sync is input; Calculating a horizontal line section in which a caption signal is displayed from counting values of the start point and the end point; And adjusting the vertical center of the screen by the calculated horizontal line section.
