Abstract

본 발명은 자막처리기능을 갖춘 텔레비전에 관한 것으로, 방송신호의 재생과 외부적인 AV신호를 선택적으로 재생하는 CRT장치를 구비한 텔레비전에 있어서, 비디오신호처리수단에 인가되는 영상신호에 포함된 자막의 표시를 지정하기 위한 키입력수단과, 그 키입력수단에 의해 자막표시가 지정되면 영상신호에 포함된 자막코드에 의한 자막데이터의 생성을 제어하는 제어수단, 상기 영상신호에 포함된 자막코드를 수신하여 검출하는 자막코드수신수단, 상기 자막코드에 대응하는 자막데이터가 저장된 자막데이터기억수단, 상기 제어수단의 제어하에 자막데이터를 화면표시 자막신호로서 발생하는 OSD발생수단 및, 상기 제어수단의 제어하에 고속으로 스위칭되어 상기 비디오신호처리수단에 의해 처리된 영상과 상기 OSD발생부에 의해 발생된 화면표시 자막신호를 중첩 처리하는 스위칭수단을 구비하여 구성되어, 영상신호에 포함된 자막코드가 검출되면 그 자막코드에 대응하는 자막데이터를 화면표시를 위한 OSD신호로 발생하고 그 OSD신호를 영상신호와 고속으로 스위칭함으로써 영상신호와 자막이 중첩되어 CRT장치상에 표시되도록 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television having a caption processing function, comprising: a television having a CRT apparatus for reproducing a broadcast signal and selectively reproducing an external AV signal. Key input means for designating a display, control means for controlling the generation of caption data by the caption code included in the video signal when the caption display is designated by the key input means, and receiving the caption code included in the video signal. Subtitle code receiving means for detecting the subtitle code, subtitle data storage means for storing subtitle data corresponding to the subtitle code, OSD generating means for generating subtitle data as a screen displaying subtitle signal under the control of the control means, and under the control of the control means. Switched at high speed and processed by the video signal processing means and screen display generated by the OSD generator And a switching means for superimposing the caption signal. When caption code included in the video signal is detected, the caption data corresponding to the caption code is generated as an OSD signal for screen display, and the OSD signal is converted into a video signal and a high speed signal. By switching to, the video signal and the subtitle are superimposed and displayed on the CRT device.

Claims

A television comprising a CRT apparatus for reproducing a broadcast signal and selectively reproducing an external AV signal, comprising: key input means for designating display of a subtitle included in a video signal applied to a video signal processing means, and a key input thereof Control means for controlling the generation of caption data by the caption code included in the video signal when the caption display is designated by the means, caption code receiving means for receiving and detecting the caption code included in the video signal, and corresponding to the caption code. Subtitle data storage means for storing subtitle data stored therein, OSD generating means for generating subtitle data as a screen displaying subtitle signal under the control of the control means, and being controlled at high speed under the control of the control means and processed by the video signal processing means. And switching means for superimposing an image and a screen display caption signal generated by the OSD generator. Television with subtitle processing, characterized in that.
