Description

더블 스캔 PIP기능을 갖는 텔레비죤회로Television circuit with double scan PIP function

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제2도는 본 발명에 따른 더블 스캔 PIP기능을 갖는 텔레비젼회로도.2 is a television circuit diagram having a double scan PIP function according to the present invention.

Claims (1)

텔레비죤신호를 수신하여 원하는 채널을 선국하게 하는 튜너(30), 튜너 인터페이스회로(31), 마이크로 프로세서(32) 및 검파회로(33)를 구비하여 VTR의 비데오신호와의 주화면 및 부화면을 디스플레이하는 더블 스캔 PIP기능을 갖는 텔레비죤신호에 있어서, 상기의 마이크로프로세서(32)에 의해 다른 채널을 선국하는 튜너(34), 튜너 인터페이스회로(35) 및 검파회로(36)를 구비하고, 상기 검파회로(33)(36)의 두 출력을 VTR의 비데오신호를 공통으로 인가하는 전환스위치(37)(38)에 각기 제공하며, 상기 주화면 전환스위치(38)에서 선택되며 출력하는 주화면 합성 비데오신호는 PIP 모듈(100)의 스위칭 및 인코더회로(44)에 제공하고, 상기 부화면 합성 비데오신호는 PIP 모듈(100)의 아날로그-디지탈변환기(42)를 거쳐 메모리(42)에 저장되게 연결하며, 상기의 부화면 합성 비데오신호는 동기검출 및 PLL회로(39)를 거쳐 타이밍 제어용 클럭발생기(40)에 인가되고, 상기 클럭발생기(40)의 제어신호에 의해 메모리(41)에서 독출된 데이터는 디지탈-아날로그 변환기(43)를 거쳐 PIP용 신호로 변환되어 스위칭 및 인코더회로(44)의 다른 입력단자에 인가되며, 상기 스위칭 및 인코더회로(44)에서 출력되는 PIP용 합성 비데오신호를 더블 스캔 프로세서(45)에 인가되고, 상기의 마이크로프로세서(32)에서 출력되는 스위치 전환신호 S1과 S2및 S3을 전환스위치(37)(38)와 스위칭 및 인코더회로(44)의 제어단자에 각각 인가되며, 상기 클럭발생기(40)의 샘플링신호 및 제어신호를 아날로그 디지탈 변환기(42), 디지탈 아날로그 변환기(43), 메모리(41)와 스위칭 및 인코더회로(44)에 인가되게 연결한 것을 특징으로 하는 더블 스캔 PIP 기능을 갖는 텔레비죤회로.A tuner 30, a tuner interface circuit 31, a microprocessor 32, and a detector circuit 33 for receiving a television signal and tuning a desired channel are displayed, and the main and sub screens of the video signal of the VTR are displayed. A television signal having a double scan PIP function, comprising: a tuner 34, a tuner interface circuit 35, and a detection circuit 36 for selecting another channel by the microprocessor 32 described above. The two outputs (33) and (36) are respectively provided to the switching switches 37 and 38 for applying the video signal of the VTR in common, and the main screen composite video signal selected and output by the main screen switching switch 38 is provided. Is provided to the switching and encoder circuit 44 of the PIP module 100, and the sub picture synthesis video signal is connected to be stored in the memory 42 via the analog-to-digital converter 42 of the PIP module 100, Sub-screen composite bidet above The erroneous signal is applied to the timing control clock generator 40 via the synchronous detection and PLL circuit 39, and the data read out from the memory 41 by the control signal of the clock generator 40 is digital-to-analog converter 43. The PIP signal is converted into a PIP signal and applied to another input terminal of the switching and encoder circuit 44, and the PIP composite video signal output from the switching and encoder circuit 44 is applied to the double scan processor 45. The switch switching signals S 1 , S 2, and S 3 output from the microprocessor 32 are applied to the switch 37 and the control terminal of the switching and encoder circuit 44, respectively, and the clock generator ( 40 has a double scan PIP function characterized in that the sampling signal and the control signal are connected to the analog digital converter 42, the digital analog converter 43, the memory 41 and the switching and encoder circuit 44 so as to be applied.
