본 위치은 T.V나 모니터의 CRT 조정, 극 화면의 크기, 위치등에 따른 편향값 조정이나 색상을 조정할 때, 그 기본이 되는 패턴을 문자발생기를 이용하여 발생하도록 하는 패턴 발생기에 관한 것이다.This position relates to the pattern generator that generates the basic pattern by using the character generator when adjusting the color of the T.V or the CRT of the monitor, adjusting the deflection value or color according to the size and position of the screen.

제1도에 도시한 종래의 패턴 발생기를 살펴보면, 수정발진기에서 발진신호 0.378MHz와 3.564MHz를 발생하고, 분주회로는 발진신호 0.378MHz를 인가받아 수직, 수평 등이 신호를 발생하고, 여기서 수평귀선 소거 펄스 합성회로와 횡선 펄스 합성회로를 연결하여 각각으로부터 합성신호를 얻어 복합 영상 신호 발생회로에 인가 시킨다. 복합 영상 신호 발생회는 상기 신호와 크로마 게이트로부터 화면 합성 신호를 받아 패턴 선택부로부터 하이드-웨어적으로 선택한 패턴으로써 새로운 합성신호를 변조회로로 인가시켜 변조회로에서 영상 반송파 발진회로로부터 채널 선택부로써 채널이 선택된 영상 반송파와 같이 고주파 변조되어, 패턴이 고주파로 출력된다.Referring to the conventional pattern generator shown in FIG. 1, the oscillation signals 0.378 MHz and 3.564 MHz are generated by the crystal oscillator, and the division circuit receives the oscillation signal 0.378 MHz to generate vertical, horizontal, and the like signals, where the horizontal retrace is performed. An erasing pulse synthesizing circuit and a horizontal pulse synthesizing circuit are connected to each other to obtain a synthesized signal from each, and apply the synthesized signal to the composite image signal generating circuit. The composite video signal generation circuit receives the screen composite signal from the signal and the chroma gate, and selects a new composite signal from the pattern selector to the modulation circuit by applying a new composite signal to the modulation circuit. The channel is high frequency modulated like the selected video carrier, and the pattern is output at high frequency.

이와같은 동작을 하는 종래의 패턴 발생기는 복잡한회로 구성품으로 인한 기기의 유지가 어렵고 가격 또한 비싸지는 문제점이 발생했다. 본 발명에 이용되는 문자 발생기의 출력특성, 즉, 문자발생기에서 출력된 문자는 일종의 패턴화된 신호원으로써 RGB등 비데오 시그날이다.Conventional pattern generators, which operate in this way, have problems that are difficult to maintain and expensive due to complicated circuit components. The output characteristic of the character generator used in the present invention, that is, the character output from the character generator is a video signal such as RGB as a kind of patterned signal source.

이와같은 특성을 가진 문자발생기를 이용하여, 본 발명은 마이크로 컴퓨터와 함께 TV의 CRT조정 패턴을 다양하게 출력하여 상기의 문제점을 해결하는데 그 목적이 있다.The object of the present invention is to solve the above problems by variously outputting a CRT adjustment pattern of a TV with a microcomputer using a character generator having such characteristics.

이와 제2도와 제3도를 참조하여 본 발명의 작용효과를 상세하게 설명한다. 제2도는 본 발명의 회로 구성도이며, 제3도는 본 발명의 패턴 발생 흐름도를 나타낸 플로우 챠트이다. 제2도에 도시한 본 발명은 회로를 동작시키는 전원부(100)와 수직, 수평 동기 신호를 문자발생기에 공급하는 수직, 수평 동기 회로(200)를 문자발생기(400)에 연결하고, 여기에 외부에 설치된 패턴 선택 키(700)로부터 패턴을 선택하여 문자발생기(400)의 출력을 제어하는 마이크로 컴퓨터(300)가 연결된다. 그리고, 문자발생기(400) 출력단에 변조기(500)를 연걸하여 영상반송파 발진회(600)로부터 영상 반송파를 얻어 문자 신호와 같이 고주파 변조하여 고주파된 패턴을 출력하는 구성을 특징으로한다.2 and 3 will be described in detail the operation and effect of the present invention. 2 is a circuit diagram of the present invention, and FIG. 3 is a flowchart showing a pattern generation flowchart of the present invention. In the present invention shown in FIG. 2, the power supply unit 100 for operating a circuit and the vertical and horizontal synchronizing circuits 200 for supplying the vertical and horizontal synchronizing signals to the character generator are connected to the character generator 400, and externally connected thereto. The microcomputer 300 for controlling the output of the character generator 400 by selecting a pattern from the pattern selection key 700 installed in the is connected. In addition, the modulator 500 is connected to the output terminal of the character generator 400 to obtain an image carrier from the image carrier oscillation circuit 600, and to output a high frequency pattern by performing high frequency modulation as a text signal.

이와같은 구성을 가진 발명의 문자발생기를 이용한 패턴 발생기에 있어서, 기본적으로 문자발생기(400)가동작하기 위해서는 전원은 물론 T.V방송에서와 같은 수직, 수평 동기 신호가 필요하게 되는데, 이는 각각 60Hz, 15.75KHz로써 출력 시그날의 기준(Reterence)이 된다. 이와같은 신호가 최초 전원부(100)로 전원이 인가되고, 수직, 수평 동기 회로(200)에서 문자발생기(400)수직, 수평 동기 신호가 인가되면 첨부도면 제3도에 도시된 플로우 챠트와 같이 최초 마이크로 컴퓨터(300)가 리셋트 상태가 되고 문자 발생기(400)도 문자를 발생한 초기 단계가 된다. 이때의 마이크로 컴퓨터(300)는 외부에 있는 패턴 선택기(700)로부터 사용자가 원하는 패턴을 선택하여 해당 서브푸틴으로 점프(Jump)하여 그때의 제어신호와 데이터 값을 문자 발생기(400)에 인가시킨다. 문자 발생기(400)는 인가 신호에 따라 문자 혹은 패턴을 출력하는데 이는 RGB등 비데오 시그날로써 변조기(500)로 인가되어 영상 반송파 발진회로(600)로부터 특정 찬넬로 셋팅되어있는 즉 패턴을 실을 수 있도록 한 영상 반송파와 같이 고주파 변조패턴 시그날이 고주파로 출력된다.In the pattern generator using the character generator of the invention having such a configuration, in order for the character generator 400 to operate basically, the vertical and horizontal synchronizing signals as in TV broadcasting are required as well as 60 Hz and 15.75, respectively. KHz is the reference of the output signal. When such a signal is initially supplied to the power supply unit 100, and the vertical and horizontal synchronizing signals are applied from the vertical and horizontal synchronizing circuits 200, as shown in the flowchart shown in FIG. The microcomputer 300 is in a reset state, and the character generator 400 also becomes an initial stage of generating characters. At this time, the microcomputer 300 selects a pattern desired by the user from the external pattern selector 700 and jumps to the corresponding subputin to apply the control signal and data value at that time to the character generator 400. The character generator 400 outputs a character or a pattern according to an applied signal, which is applied to the modulator 500 as a video signal such as RGB so that the pattern is set to a specific channel from the image carrier oscillation circuit 600 so as to load a pattern. Like a video carrier, a high frequency modulation pattern signal is output at a high frequency.

이와 같은 동작과정에서 마이크로 컴퓨터(300)는 문자발생기(400)를 최기화(INITIALIZE) 하고 패턴 선택키(700)에 따른 다양한 패턴을 선택하여 문자 발생기(400)에 인가 할 때, 키 선택에 따른 프로그램에 따라서 특정시간동안 특정 패턴을 출력시키고, 또 다른 특정시간 동안에는 또 다른 패턴을 출력하는 등의 순차적 패턴을 발생함으로써 패턴을 돌려가며 셀트 테스팅하고, 문자 발생기(400)를 소프트 웨어적으로 제어하기 때문에 기준의 패턴 발생기보다 다양한 패턴을 구사할 수 있는 잇점이 생기는 동시에 구성에 있어서도 간단하여 기기의 유지가 용이해지며 경제적인 잇점이 있다.In such an operation process, the microcomputer 300 initializes the character generator 400 and selects various patterns according to the pattern selection key 700 and applies them to the character generator 400 according to the key selection. Depending on the program, it generates a sequential pattern such as outputting a specific pattern for a specific time, and outputting another pattern for another specific time, and then cel testing the pattern by turning the pattern and controlling the character generator 400 in software. Therefore, there is an advantage that can use a variety of patterns than the standard pattern generator, and at the same time, the configuration is simple and easy to maintain the device, there is an economic advantage.

아울러 본 발명의 문자 발생기(400)의 수직, 수평 동기 신호핀(Pin)에 직접 텔레비젼 셀트의 수직, 수평 동기신호를 넣어주면서, 문자 발생기(400)의 출력을 텔레비젼의 비데오 시그날에 심어주면 텔레비젼 생산라인에서 기존의 패턴 발생기로 패스팅하는 것보다 훨씬 간편하고, 정확하며 경제적인 패턴 발생기를 구성하기도 한다.In addition, when the output of the character generator 400 is planted on the video signal of the television, the television is produced by inserting the vertical and horizontal synchronizing signals of the television cell directly into the vertical and horizontal synchronizing signal pins of the character generator 400 of the present invention. It is much simpler, more accurate, and more economical than producing fast pattern generators in line.
