Abstract

본 발명은 OSD(On Screen Display)기능을 구비한 텔레비전수상기에 관한 것으로서, 특히 시청자가 영화, 음악, 교양, 스포츠 등 자신이 원하는 특정내용의 채널을 탐색, 선국할 때 방송신호에 방송내용을 식별시켜주는 파일롯트신호가 실려 있으면 이를 검출하여 시청자에게 선국된 방송의 내용을 일정시간동안 OSD문자나 도형으로 알려 주도록 하여 시청자가 시청하고자 하는 특정방송내용의 채널을 신속하게 탐색, 선국할 수 있게 하는 텔레비전수상기의 방송내용판별방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television receiver having an On Screen Display (OSD) function. In particular, when a viewer searches for and tunes a channel of a specific content such as movie, music, culture, and sports, the broadcaster is identified in the broadcast signal. When the pilot signal is loaded, it detects it and informs viewers of the tuned broadcast contents with OSD text or graphics for a certain time so that viewers can quickly search and tune into the channel of specific broadcast contents they want to watch. A method for discriminating broadcast contents of a television receiver.

본 발명의 방법은 키입력부(9)로부터의 신호에 의하여 파워온 또는 채널변경이 되는지를 판단하여, 파원온 또는 채널변경이 실행된 경우에 파일롯트신호검출부(30)로부터의 신호에 의해서 현 채널의 방송신호에 파일롯트신호가 포함되어 있는지를 판단하고, 현 채널의 방송신호에 파일롯트신호가 포함되어 있는 경우에 파일롯트신호검출부(30)로부터 인가되는 코드신호에 의해서 현 채널의 방송내용을 판별하며, OSD발생부(12)를 제어하여 방송내용의 표시에 대응하는 R,G,B신호및 OSD블랭킹신호(Y')를 출력토록 하는 것을 특징으로 한다.The method of the present invention determines whether the power-on or channel change is made by the signal from the key input unit 9, and the current channel by the signal from the pilot signal detection unit 30 when the wave-on or channel change is executed. It is determined whether the pilot signal is included in the broadcast signal of the broadcast signal. If the pilot signal is included in the broadcast signal of the current channel, the broadcast content of the current channel is determined by the code signal applied from the pilot signal detector 30. And discriminate and control the OSD generator 12 to output the R, G, B signal and the OSD blanking signal Y 'corresponding to the display of the broadcast contents.

Claims

A television receiver comprising a pilot signal detector (30) for detecting a pilot signal identifying a broadcast content, comprising: a first step of determining whether power-on or channel change is made by a signal from a key input unit (9); A second step of determining whether the pilot signal is included in the broadcast signal of the current channel by the signal from the pilot signal detection unit 30 when power-on or channel change is performed; A third step of determining the broadcast contents of the current channel according to a code signal applied from the pilot signal detector 30 when the pilot signal is included in the broadcast signal; A fourth step of controlling the OSD generator 12 to output the R, G, B signals and the OSD blanking signal Y 'corresponding to the display of the broadcast contents; A fifth step of determining whether a predetermined time has elapsed after outputting the signal and the OSD blanking signal (Y ′), and when the predetermined time has elapsed, the OSD generator 12 is controlled to control the R, G, B signals, and OSD blocking. And a sixth step of terminating the output of the signal (Y ').
