Abstract

본 발명은 티브이의 더블윈도우신호 출력장치에 관한 것으로, 종래의 더블윈도우 티브이는 모니터로는 두 화면을 볼 수 있어도, 모니터출력단자부에는 한 화면 즉, 주영상신호 및 음성신호만이 인가되기 때문에, 모니터출력단자부를 통해서는 한 화면의 영상 및 음성신호만이 녹화되는 문제점이 있었다. 본 발명은 이러한 종래의 문제점을 해결하기 위해 주방송신호 또는 부방송신호 또는 외부기기로부터의 음/영상신호를 입력받아 이를 음/영상선택신호에 따라 주화면신호와 부화면신호로 분리하여 출력하는 음성/영상절환스위칭부와; 상기 음성/영상절환스위칭부로부터 출력되는 주화면 및 부화면신호가 신호분리부에 의해 휘도/색신호분리 및 색차신호로 분리되면 이를 입력받아 더블윈도우신호로 처리하여 출력하는 더블윈도우처리부와; 선택신호에 따라 주영상 색차신호와 상기 더블윈도우처리부의 색차신호를 선택하여 색신호매트릭스부를 통해 모니터에 출력하는 색차신호스위칭부와; 상기 더블윈도우처리부의 출력 색차신호를 NTSC더블윈도우 컴포지트신호로 변환하여 출력하는 엔코더와; 상기 엔코더의 더블윈도우 영상신호와 상기 음성/영상절환스위칭부의 주음성신호 및 부음성신호를 외부기기로 전달하기 위한 더블윈도우모니터출력단자부로 구성한 티브이의 더블윈도우신호 출력장치를 창안한 것으로, 이의 작용을 통해 더블윈도우상태의 화면 및 음성을 그대로 녹화할 수 있어, 이를 나중에 재생시 어떠한 티브이에서도 더블윈도우 상태의 화면을 그대로 시청할 수 있는 효과가 있다.The present invention relates to an apparatus for outputting a double window signal of a TV. In the conventional double window TV, even though two screens can be viewed by a monitor, only one screen, that is, a main video signal and an audio signal, is applied to the monitor output terminal. There was a problem that only the video and audio signal of one screen is recorded through the monitor output terminal. In order to solve the conventional problems, the present invention receives a main broadcast signal, a sub-broadcast signal, or a sound / video signal from an external device, and separates the sound into a main picture signal and a sub picture signal according to the sound / video selection signal. Image switching switching unit; A double window processing unit which receives the main screen and the sub picture signals output from the audio / video switching switching unit into a luminance / color signal separation and a color difference signal by a signal separation unit, and processes the same as a double window signal; A color difference signal switching unit for selecting a main image color difference signal and a color difference signal of the double window processing unit according to a selection signal and outputting the color difference signal to a monitor through a color signal matrix unit; An encoder for converting the output color difference signal of the double window processing unit into an NTSC double window composite signal and outputting the converted color difference signal; Invented a TV double window signal output device composed of a double window monitor output terminal unit for transmitting the double window video signal of the encoder, the main audio signal and the sub-audio signal of the audio / video switching switching unit to an external device, its operation Through the double-window state screen and the voice can be recorded as it is, when playing it later there is an effect that you can watch the double-window state screen in any TV as it is.
