Abstract

본 발명은 PIP(Picture In Picture)기능을 갖는 텔레비젼 방송 수신장치에 관한 것으로 특히, 안테나에 병렬연결되고, 제어신호에 따라 수신되는 방송신호를 선국하는 제1, 제2튜너와: 제1, 제2튜너로부터 선국되어 출력되는 신호를 입력받아 증폭한 후 영상신호와 음성신호로 구분하여 출력하는 제1, 제2신호처리부와: 제1신호처리부에서 출력되는 신호를 입력받아 제어신호 입력이 없는 경우 주화면 처리 수단에 전달하고 제어신호 입력시 PIP 부화면 처리수단에 전달하는 제1스위치와: 제2신호 처리부에서 출력되는 신호를 입력받아 제어신호 입력이 없는 경우 PIP 부화면 처리수단에 전달하고 제어신호 입력이 접지로 도통시키는 제2스위치와: 주화면을 통하여 특정 방송신호를 시청하는 중에 안내 방송이나 문자방송을 사용자가 선택하는 경우에 이를 감지하고, 주화면에 디스플레이되던 방송을 PIP 부화면에 디스플레이시키도록 상기 제1, 제2스위치에 제어신호를 인가하는 마이크로 프로세서를 포함하는 것을 특징으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television broadcast receiver having a picture in picture (PIP) function, and more particularly, comprising: first and second tuners connected in parallel to an antenna and tuned to a broadcast signal received according to a control signal; First and second signal processing unit for receiving and amplifying the signal output from the tuner 2 and amplified and then divided into a video signal and an audio signal: When there is no control signal input by receiving the signal output from the first signal processing unit A first switch which is transmitted to the main screen processing means and transmitted to the PIP sub-screen processing means when the control signal is input: receives a signal output from the second signal processing part and transmits it to the PIP sub-screen processing means when there is no control signal input; A second switch to which the signal input is conducted to ground: detects when the user selects the announcement or text broadcasting while watching a specific broadcast signal through the main screen; And the release of the broadcast displayed on the main screen, characterized in that it comprises a microprocessor for applying a control signal to the first and the second switch so as to display a PIP sub-screen.

이에 따라, 사용자가 안내방송이나 문자방송을 시청하기 위하여 일시정지 모드를 선택하는 경우, 주화면이 일시 정지된 상태로 안내방송이나 문자방송이 오버랩되는 주화면에서 디스플레이되던 방송이 부화면에 디스플레이됨에 따라, 현재까지 사용자가 시청하던 주화면에서 더 이상 시청할 수 없게 되는 문제점을 해소하는 효과가 있다.Accordingly, when the user selects the pause mode in order to watch the announcement or the text broadcast, the broadcast that was displayed on the main screen where the announcement or the text broadcast is overlapped is displayed on the sub screen while the main screen is paused. Accordingly, there is an effect of solving the problem that the user can not watch anymore on the main screen that has been viewed so far.

제2도는 본 발명에 따른 일시 정지 모드시의 PIP 절환기능을 갖는 PIP 기능의 텔레비젼의 블록 구성도.2 is a block diagram of a television having a PIP function having a PIP switching function in a pause mode according to the present invention.

Claims (1)

공중파 방송신호를 수신하여 브라운관에 디스플레이할 때 주화면과 주화면 내에 디스플레이되는 부화면을 동시에 디스플레이 시킬 수 있는 PIP 기능을 갖는 텔레비젼 방송 수신장치에 있어서, 안테나에 병렬 연결되고 제어신호에 따라 수신되는 방송신호를 선국하는 제1, 제2튜너와, 상기 제1, 제2튜너에 각각 일대일로 매칭 연결되어 있으며 해당 튜너로부터 선국되어 출력되는 중간주파수 신호를 입력받아 증폭한 후 영상신호와 음성신호로 구분하여 출력하는 제1, 제2신호처리부와, 상기 제1신호 처리부에서 출력되고 아날로그 전기신호를 입력받아 제어신호 입력이 없는 경우 a접점을 통하여 주화면 처리 수단에 전달하고 제어신호 입력시 b접점으로 절환하여 PIP 부화면 처리수단에 전달하는 제1스위치와, 상기 제2신호 처리부에서 출력되는 아날로그 전기신호를 입력받아 제어신호 입력이 없는 경우 a접점을 통하여 PIP 부화면 처리수단에 전달하고 제어신호 입력시 b접점으로 절환하여 접지로 도통시키는 제2스위치, 그리고, 상기 주화면을 통하여 특정 방송신호를 시청하는 중에 안내 방송이나 문자방송을 사용자가 선택하는 경우에 이를 감지하여 상기 제1, 제2스위치의 연결 접점을 a접점에서 b접점으로 전환시키는 제어신호를 상기 제1, 제2스위치에 인가하여 주화면에 디스플레이되던 방송을 PIP 부화면에 디스플레이시키도록 하는 마이크로 프로세서를 포함하는 것을 특징으로 하는 일시 정지 모드시의 PIP 절환 장치.A television broadcast receiving apparatus having a PIP function capable of simultaneously displaying a main screen and a sub-screen displayed in the main screen when receiving an over-the-air broadcast signal and displaying the same on a CRT, comprising: a broadcast connected in parallel to an antenna and received according to a control signal The first and second tuners for tuning the signal are matched to the first and second tuners in a one-to-one correspondence, respectively, and are divided into a video signal and an audio signal after receiving and amplifying an intermediate frequency signal tuned and output from the corresponding tuner. The first and second signal processing units output from the first and second signal processing units, and receive the analog electric signal and transmit the analog signal to the main screen processing means through the contact a, and to the contact b when the control signal is input. A first switch for switching and transferring the PIP sub-screen processing means, and an analog output from the second signal processing unit When the control signal is input and there is no control signal input, the second switch transmits the signal to the PIP sub-screen processing means through the contact point and switches to the contact point b when the control signal is input, and conducts it to the ground, and transmits a specific broadcast signal through the main screen. When the user selects a guide broadcast or a text broadcast while watching, a control signal for switching the connection contact of the first and second switches from the a contact to the b contact is applied to the first and second switches. And a microprocessor for displaying the broadcast displayed on the main screen on the PIP sub-screen. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
