Abstract

본 발명은 채널설정과 프로그램시청을 동시에 할 수 있는 영상기기의 자화면을 통한 채널설정방법 및 그 장치에 관한 것이다. 본 발명은 키입력수단을 이용하여 채널설정키신호를 입력하면 마이컴이 자화면을 채널설정모드로 전환하여 안내문구가 표시되도록 한다. 이후, 모화면영상처리부로부터 동기신호의 입력여부에 따라 모화면에 소정 채널의 영상을 표시한 다음 자화면에 나타나는 안내문구를 보면서 채널설정을 의한 키조작을 행하여 원하는 채널을 메모리에 기억킨다. 이에 따라, 채널선택시 설정된 채널을 신속하게 선국할 수 있을 뿐만 아니라 모화면을 통해 프로그램의 시청을 동시에 할 수 있는 장점이있다.The present invention relates to a channel setting method and apparatus therefor through a child screen of a video device capable of simultaneously setting a channel and watching a program. According to the present invention, when the channel setting key signal is input by using the key input means, the microcomputer switches the sub screen to the channel setting mode so that a guide phrase is displayed. Thereafter, a predetermined channel image is displayed on the mother screen according to whether or not a synchronization signal is input from the mother screen image processing unit, and key operation by channel setting is performed while the guide phrase appearing on the mother screen is stored in the memory. Accordingly, there is an advantage that it is possible not only to select a channel quickly when selecting a channel, but also to simultaneously watch a program through a mother screen.

Claims

A video apparatus for setting a desired channel by using a PIP function of displaying a reduced child screen on a mother screen, comprising: key input means for keying in channel setting and basic functions; A sub-screen image processing unit which outputs a sub-screen signal which is reduced by selecting the first channel according to the first selection signal of the microcomputer and outputs a sub-screen signal for the channel setting mode when a mode switching signal is input; A mother screen image processing unit for tuning the second channel according to the second selection signal of the microcomputer and outputting a vertical / life synchronous signal of the tuned channel; Receives a predetermined key signal from the key input means, and when a channel setting key signal for instructing channel setting is input, outputs a mode switching signal for switching the child screen to the channel selection mode, and displays an image of a predetermined channel on the mother screen. A microcomputer for outputting a second selection signal for displaying and outputting a second selection signal for displaying a guide character on the sub-screen, and outputting an OSD control signal for displaying the guide character on the sub-screen; And an OSD unit receiving the OSD control signal from the microcomputer and outputting a corresponding OSD text signal.

The apparatus of claim 1, wherein the microcomputer outputs an OSD control signal corresponding to the guide character data read from the memory when the OSD control signal for the guide character is output.

The magnetic screen of claim 1, wherein the microcomputer outputs a second selection signal so that a contracted channel is displayed on the mother screen when the vertical / horizontal and synchronization signals are not input from the mother screen image processor. Channel setting device through.

A method for selecting a desired channel in a video device having a PIP function, the method comprising: determining whether a key signal generated by a key input means is a channel setting key signal for setting a channel; Switching the child screen to the channel setting mode if the determination result of the determining step is a channel setting key signal; Determining whether a vertical / horizontal synchronization signal is input from a mother screen image processor to display a predetermined channel on the mother screen; Displaying a channel or a tuned channel contracted on the mother screen; Reading guide text data from a memory and displaying an OSD control signal corresponding to the guide text on a display screen; And setting a predetermined channel through a key operation and storing the set channel in a memory.

The method of claim 4, wherein displaying the channel as contracted on the mother screen comprises: reading a designated channel data of the mother screen stored in a memory; and selecting a channel corresponding to the designated channel data. Channel setting method through the child screen of the video device comprising the step of outputting.
