본 고안은 PIP(Picture In Picture)기능을 갖는 VCR의 레코딩 신호표시 회로에 관한 것으로, 특히 실제로 기록되는 신호를 사용자가 쉽게 확인할 수 있도록 한 것이다.The present invention relates to a recording signal display circuit of a VCR having a picture in picture (PIP) function, and in particular, allows a user to easily check a signal actually recorded.

종래에는 제3도에 도시된 바와같이 입력신호(S1)(S2)단에 스위칭 IC(1)를 통하여 모화면과 자화면을 만드는 PIP 합성기(4)를 접속하였고, 이 PIP 합성기(4)의 출력단에는 Y/C 기록계(5)를 접속하였으며, 상기의 스위칭 IC(1)와 PIP 합성기(4)에 PIP 제어신호가 인가되도록 하였다.Conventionally, as shown in FIG. 3, a PIP synthesizer 4 for creating a mother screen and a child screen is connected to the input signal S 1 and S 2 through a switching IC 1, and the PIP synthesizer 4 The Y / C recorder 5 is connected to the output terminal of the C1, and a PIP control signal is applied to the switching IC 1 and the PIP synthesizer 4 above.

이와 같이 구성된 종래의 회로에서는 두 입력신호를 스위칭 IC(1)를 이용하여 메인신호, 서브신호로 구성한 후 PIP 합성기(4)에서 이를 모화면, 자화면으로 합성하여 출력시키는데, 이때 PIP 인버터 모드가 되면 모화면, 자화면이 서로 바뀌게 되므로 레코드 모드에서는 이를 판별기록할 수가 없어 강제적으로 PIP를 해제시키고 있다.In the conventional circuit configured as described above, the two input signals are composed of the main signal and the sub-signal by using the switching IC 1, and then the PIP synthesizer 4 synthesizes them into a mother screen and a child screen, and outputs the PIP inverter mode. If the parent screen and the child screen are changed to each other, it is impossible to discriminate and record them in the record mode, thereby forcibly releasing the PIP.

즉, 종래 기술에서는 레코드시 PIP 모드 절환이 불가능하므로 실제적으로 A라는 입력신호를 녹화하면서 B라는 신호를 볼 수가 없는 결점이 있었다.That is, in the prior art, since the PIP mode switching is impossible during recording, there is a drawback that the signal B cannot be seen while recording the input signal A.

본 고안은 이와 같은 종래의 결점을 감안하여 안출한 것으로 레코드 모드에서 PIP 기능수행이 가능하도록 함은 물론 사용자가 실제 기록되고 있는 신호가 어떤 것인지를 쉽게 확인할 수 있도록 한 것인바, 이를 첨부된 도면 제1도와 제2도에 의하여 더욱 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-mentioned drawbacks, and it is possible to perform the PIP function in the record mode as well as to make it easy for the user to check what is actually being recorded. 1 and 2 will be described in more detail as follows.

본 고안은 입력신호(S1)(S2)와 이 신호중 실제로 레코드 하고자 하는 신호를 선택하는 스위칭 IC(1), 이 레코드 하고자 하는 신호가 PIP 모드에서 인버트 모드로 절환시에도 녹화신호로 확인될 수 있도록 표시하여 주는 OSD(ON SREEN DISPLAY)신호(S3), OSD신호(S3)와 제1스위칭 IC에서 선택된 입력신호(S1또는 S2)를 합성하기 위한 믹서(3), 인버트 모드에서 입력신호(S1,S2)중 어느 신호를 메인신호와 서브신호로 할것인가를 구분하는 스위칭 IC(2), 스위칭 IC(2)에서 구분된 서브신호와 메인신호를 합성하여 PIP 신호를 만드는 PIP 합성기(4), 상기 믹서(3)와 스위칭 IC(2) 사이에 접속되어 믹서(3)로부터의 신호를 기록하는 Y/C 기록계(5), 및 레코드 모드에서만 메인신호가 OSD 신호를 합성하도록 하는 OSD 신호선택부(6)인 스위칭 트랜지스터(Q)와 제어신호로 구성된다.The present invention is a switching IC (1) that selects an input signal (S 1 ) (S 2 ) and a signal to be actually recorded, and the signal to be recorded is confirmed as a recording signal even when the signal to be recorded is switched from the PIP mode to the invert mode. OSD (ON SREEN DISPLAY) signal (S 3 ) to display so that the display, the mixer (3), the invert mode for synthesizing the OSD signal (S 3 ) and the input signal (S 1 or S 2 ) selected from the first switching IC In the switching IC (2), which distinguishes which of the input signals (S 1 , S 2 ) to be the main signal and the sub-signals, the PIP signal is synthesized by synthesizing the divided sub-signals and main signals from the switching IC (2). A PIP synthesizer (4) to make, a Y / C recorder (5) connected between the mixer (3) and the switching IC (2) to record the signal from the mixer (3), and the main signal in the record mode only It consists of a switching transistor Q, which is an OSD signal selecting section 6, and a control signal for synthesizing.

단, OSD 신호는 기존에 OSD에 사용되는 IC를 이용하여 화면상의 특정위치에 "MAIN"이라는 문자를 표시하도록 프로그램되어 있는 것을 사용하여 출력되는 신호를 말하며, S5는 입려선택 신호로 일반적으로 사용되는 튜너/라인 신호의 선택에 사용되는 신호이다.However, the OSD signal refers to a signal that is output by using a program that is conventionally programmed to display the character "MAIN" at a specific position on the screen using the IC used in the OSD, and S 5 is generally used as an input selection signal. This signal is used to select a tuner / line signal.

이와 같이 구성된 본 고안은 2개의 입력신호(S1)(S2)중 실제로 레코드하고자 하는 신호를 스위칭 IC(1)에서 선택하여 레코드 모드가 되면 트랜지스터(Q)가 온되어 입력되는 메인표시 OSD 신호(S3)를 믹서(3)에서 스위칭 IC(1)에서 선택한 신호와 합성하여 이 신호를 별도로 Y/C 기록계(5)로 보냄과 동시에 메인신호와 서브신호를 구분하는 스위칭 IC(2)로 입력시킨다.According to the present invention configured as described above, the main display OSD signal is input when the transistor Q is turned on when the switching IC 1 selects a signal to be actually recorded among the two input signals S 1 and S 2 . (S 3 ) is combined with the signal selected by the switching IC (1) in the mixer (3) to send this signal separately to the Y / C recorder (5) and to the switching IC (2) which distinguishes the main signal from the sub-signals. Enter it.

예를 들어, 레코드 하고자 하는 신호가 A라면 A신호에 메인표시 OSD 신호(S3)가 믹서(3)에서 합성되어 스위칭 IC(2)를 거쳐 메인신호가 되고, 이 신호가 PIP 합성기(4)를 통하여 합성된 PIP 화면의 제2a도와 같은 모화면이 되는 것이며, PIP 화면의 자화면은 A신호를 녹화하면서 보고자 하는 B 신호가 된다.For example, if the signal to be recorded is A, the main display OSD signal S 3 is synthesized by the mixer 3 in the mixer 3 to become the main signal through the switching IC 2, and the signal is the PIP synthesizer 4. It becomes a mother screen as shown in FIG.

여기서 PIP 인버트(S4)가 입력되면 스위칭 IC(2)에서 메인신호와 서브신호가 상호 절환되어 PIP 합성기(4)로 입력되므로 제2b도와 같이 모화면은 B신호가 자화면은 믹서(3)를 거친 A신호가 된다.In this case, when the PIP invert S 4 is input, the main signal and the sub signal are switched to each other by the switching IC 2 and input to the PIP synthesizer 4. As shown in FIG. Becomes A signal.

그러나, 레코드되는 신호는 A신호가 되는데 이는 레코드 하고자 하는 신호를 스위칭 IC(1)에서 미리 선택하였기 때문에 PIP 모드에서나 PIP 인버트 모드에서나 Y/C 기록계(5)에 기록되는 신호는 일정하게 되면 출력 화면상에는 모화면 또는 자화면상에 실제로 기록되는 신호가 OSD를 이용한 표시문자 "MAIN"이 나타나게 되는 것이다.However, the signal to be recorded becomes the A signal because the signal to be recorded is preselected by the switching IC 1 so that the signal recorded in the Y / C recorder 5 in the PIP mode or the PIP invert mode is constant and the output screen becomes constant. On the screen, the actual recorded signal on the mother screen or the child screen is displayed with the display character "MAIN" using the OSD.

이상에서 설명한 바와 같이 본 고안은 레코드 모드에서 PIP 기능수행이 가능함은 물론 이렇게 PIP 기능이 수행되면서 사용자가 실제 기록되어 있는 신호가 어떤것인지를 쉽게 확인할 수 있는 효과가 있는 것이다.As described above, the present invention is not only capable of performing the PIP function in the record mode, but also has the effect of allowing the user to easily check what is actually recorded as the PIP function is performed.
