Abstract

본 발명은 OSD기능이 구비된 텔레비젼수상기에 관한 것으로서, 특히 문자안내방송시에 현재 출력되고 있는 OSD의 문자 및 도형을 자동으로 오프하거나, 문자안내방송동안에 키입력부를 조작할 때에는 OSD의 문자 및 도형을 CRT의 화면상에 나타나지 않도록 하는 텔레비젼수상기의 문자안내방송시 OSD 자동오프방법 및 OSD 자동출력차단방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television receiver equipped with an OSD function, and in particular, to automatically turn off characters and graphics of the OSD currently being output during text guide broadcasting, or to operate the key input unit during text guide broadcasting. The present invention relates to an OSD auto-off method and OSD auto-output blocking method in a character guide broadcast of a television receiver, which is not displayed on the screen of a CRT.

본 발명은 키입력부(9)로 부터의 신호에 의해 OSD가 온되는 지를 판단하고 OSD가 온 될 경우 ID 신호검출부(30)로 부터의 신호에 의해서 IF 신호에서 문자안내방송의 ID 신호가 검출되는지를 판단하고, ID 신호가 검출될 경우에 OSD발생부(12)를 제어하여 현재 출력하고 있는 R, G, B 신호 및 OSD블랭킹신호(Y')의 출력을 오프시키는 OSD자동오프방법과 ; ID 검출부(30)로 부터의 신호에 의해서 IF 신호에서 문자안내방송의 ID 신호가 검출되는지를 판단하고, ID 신호가 검출될 경우에 키입력부(9)로 부터 신호가 입력되는 지를 판단하고, 키입력부(9)로 부터 신호가 입력될 경우에 OSD 발생부(12)로의 제어신호의 출력을 차단하는 OSD 자동출력차단방법을 특징으로 한다.The present invention determines whether the OSD is turned on by the signal from the key input unit 9, and if the ID signal of the character guide broadcasting is detected in the IF signal by the signal from the ID signal detector 30 when the OSD is turned on. And an OSD auto-off method for controlling the OSD generator 12 to turn off the output of the currently outputted R, G, B signals and the OSD blanking signal Y 'when the ID signal is detected; It is determined whether the ID signal of the character guide broadcast is detected from the IF signal by the signal from the ID detection unit 30, and if the signal is input from the key input unit 9 when the ID signal is detected, the key is determined. OSD automatic output blocking method for blocking the output of the control signal to the OSD generator 12 when a signal is input from the input unit (9).

Description

OSD auto-off method for character guide broadcasting of TV receiver

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

제2도는 본 발명의 실시예에 따른 문자안내방송시 OSD 자동오프기능을 구비한 텔레비젼수상기의 블럭도.2 is a block diagram of a television receiver having an OSD auto-off function for character guide broadcasting according to an embodiment of the present invention.

Claims

In a television receiver comprising an IF amplifier 4, a key input 9, a microprocessor 11, an OSD generator 12, and an ID signal detector 30, a signal from the key input 9 is applied to the television receiver. In the first step of determining whether the OSD is turned on by the first step, when the OSD is turned on in the first step, the character guide broadcasting is performed in the IF signal output from the IF amplifier 4 by the signal from the ID signal detector 30. A second step of determining whether an ID signal is detected, and an R, G, B signal and an OSD currently being controlled by controlling the OSD generator 12 when the ID signal of the character guide broadcast is detected in the second step. And a third step of turning off the output of the blanking signal (Y ').

The method of claim 1, wherein the first step of determining whether the ID signal of the character guide broadcast is detected in the IF signal output from the IF amplifying unit 40 in the signal from the ID signal detecting unit 30, the character in the first step A second step of determining whether a signal is input from the key input unit 9 when the ID signal of the announcement is detected, and an OSD generator if the signal is input from the key input unit 9 in the second step. And a third step of interrupting the output of the control signal to (12).
