Abstract

본 발명은 영상 기기의 자화면 표시 제어 방법 및 회로에 관한 것으로, 종래에는 자화면(PIP) 표시 기능의 영상 기기나 브이씨알에서 한 화면을 시청하면서 자화면(PIP) 표시 기능을 이용하여 다른 채널의 내용을 표시하거나 탐색할 경우 연속적으로 표시해야만 다른 채널의 프로그램 내용의 변경을 알 수 있으므로 자화면의 면적만큼 모화면이 표시되지 않는 문제점이 있었다. 이러한 점을 개선하기 위하여 본 발명은 채널의 프로그램 변경을 알고자 키를 입력하면 자화면 영상 신호의 프로그램 식별 정보를 검출하여 해당 채널의 프로그램 식별 정보에 변경이 있을 경우에만 변경된 프로그램의 내용을 일정 시간동안 자화면에 표시하므로써 프로그램 탐색시 모화면 전체를 표시하도록 구성한 것으로, 본 발명은 자화면 기능 영상 기기에 적용하면 프로그램 식별 신호를 이용하여 타 채널의 프로그램 변동 순간에 그 내용을 자화면에 신속히 표시하므로써 타 채널에 시청하고자 하는 프로그램이 있을 경우 신속한 채널 전환을 수행할 수 있고 또한, 프로그램 식별 정보를 점검하여 변동 내용이 있으면 자화면에 표시함과 동시에 세로 변동된 프로그램 식별 정보를 세팅하므로써 사용자가 해당 프로그램을 시청할 수 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a circuit for controlling the display of a child screen of a video device. In the related art, while watching a screen on a video device having a display function of a child screen (PIP) or a V-C, another channel is used by using the sub picture display function. When displaying or searching the contents of the program, the program contents of other channels must be displayed continuously so that the mother screen is not displayed as much as the area of the child screen. In order to improve this point, the present invention detects program identification information of a sub-screen video signal when a key is input to know a program change of a channel, and then, if there is a change in the program identification information of the corresponding channel, the contents of the changed program are fixed for a predetermined time. The present invention is configured to display the entire mother screen during program search by displaying on the child screen, and the present invention can quickly display the contents on the child screen at the moment of program change of another channel using a program identification signal when applied to the child screen function video apparatus. Therefore, if there is a program that you want to watch on the other channel, you can perform a quick channel switch and check the program identification information, and if there is a change, display it on the sub-screen and set the program identification information that is changed vertically. You can watch the program.

Claims (3)

프로그램 식별 정보의 변경을 판별하기 위한 모드가 설정되었는지 판별하는 제1단계와, 제1단계에서 프로그램 식별 정조의 변경 판별 모드가 설정되면 튜너를 제어하여 각 채널별 프로그램 식별 정보를 검출하여 저장하고 각 채널별 프로그램 식별 정보를 검출하여 초기의 프로그램 식별 정보와 일치하는지 비교하는 제2단계와, 제2단계에서 프로그램 식별 정보가 일치하지 않으면 해당 채널의 프로그램 식별 정보의 변경으로 인식하여 다시 프로그램 식별 정보를 세팅하고 동시에 자화면에 변경된 프로그램의 내용을 표시하는 제3단계로 이루어진 것을 특징으로 하는 영상기기의 자화면 표시 제어 방법.In the first step of determining whether the mode for determining the change of the program identification information is set, and if the change determination mode of the program identification condition is set in the first step, the tuner is controlled to detect and store program identification information for each channel. Detecting the program identification information for each channel and comparing the program identification information with the initial program identification information; and if the program identification information does not match in the second step, the program identification information of the corresponding channel is recognized and changed again. And a third step of setting and displaying contents of the changed program on the own screen at the same time. 안테나로 수신된 방송 신호중 해당 채널의 주파수를 동조시키는 튜닝 수단과, 모화면 및 상기 튜닝 수단으로부터의 자화면의 영상 신호를 입력 받아 모화면, 자화면 영상 신호를 처리하고 상기 두 신호를 중첩하여 출력하는 자화면 처리 수단과, 상기 튜닝 수단으로부터 프로그램 식별 정보를 검출하여 디코딩하는 식별 정보 검출 수단과, 상기 식별 정보를 일시 저장하는 메모리 수단과, 상기 튜닝 수단을 제어하고 상기 메모리 수단의 식별 정보와 상기 식별 정보 검출 수단의 식별 정보를 비교하여 그 결과에 따라 상기 자화면 처리 수단을 제어하는 제어 수단과, 상기 자화면 처리 수단에서 출력된 영상 신호를 영상 표시 수단에 출력하는 영상 출력 수단으로 구성한 것을 특징으로 하는 영상 기기의 자화면 표시 제어 회로.Tuning means for tuning the frequency of the corresponding channel among the broadcast signals received by the antenna, and receives the video signal of the mother screen and the mother screen from the tuning means, processes the mother screen and the mother screen video signal, and outputs the two signals superimposed Self-screen processing means, identification information detecting means for detecting and decoding program identification information from the tuning means, memory means for temporarily storing the identification information, controlling the tuning means, and identifying the identification information of the memory means and the A control means for comparing the identification information of the identification information detecting means and controlling the sub picture processing means according to the result, and an image output means for outputting the image signal output from the sub picture processing means to the image display means. A sub screen display control circuit of a video device. 제2항에 있어서, 마이크로 컴퓨터는 프로그램 식별 정보의 변경 판별 동작이 설정되면 초기에 채널별로 프로그램 식별 정보를 검출하여 메모리에 저장하기 위하여 자화면용 튜너의 동조 주파수를 순차적으로 변경시키는 것을 특징으로 하는 영상 기기의 자화면 표시 제어 회로.The method of claim 2, wherein when the change determination operation of the program identification information is set, the microcomputer sequentially changes the tuning frequency of the sub-screen tuner in order to detect the program identification information for each channel and store it in the memory. Subscreen display control circuit of video equipment. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
