Abstract

본 발명은 문자정보가 포함되어 있는 특정한 영상화면이 출력되는 경우 텔레비전 주번에 시청자가 감지되지 않을 때에는 출력되는 화면을 정지하도록 된 정지화면 출력기능을 갖춘 텔레비전 수상기에 관한 것으로, 문자정보가 포함되어 있는 방송신호에 대해서는 소정의 주파수신호를 부가하여 송출하도록 된 방송시스템에 있어서, 방송신호에 포함되어 있는 상기 소정의 주파수신호를 검출하는 주파수 검출수단과, 텔레비전 주변의 시청자를 감지하기 위한 감지수단, 방송신호로부터 검파된 영상신호의 1프레임분의 화상신호를 저장하는 화상데이터 저장수단, 상기 화상데이터 저장수단에서 독출되는 출력되는 영상신호와 방송신호로부터 검파된 영상신호를 선택적으로 스위칭하여 영상처리수단으로 출력하는 스위칭수단, 상기 주파수 검출수단에 의해 상기 소정의 주파수신호가 검출된 상태에서 상기 감지수단으로부터 소정의 감지신호가 인가되는 경우 상기 화상데이터저장수단에 그때의 영상신호를 저장하고, 상기 스위칭수단을 통해 상기 화상데이터 저장수단에 저장된 영상신호를 출력 제어하는 제어수단을 포함하여 구성된 것을 특징으로 한다.The present invention relates to a television receiver having a still picture output function that stops the output screen when a viewer is not detected at the time of television when a specific video screen including text information is output. In a broadcasting system in which a predetermined frequency signal is added to a broadcast signal and transmitted, the broadcasting system includes: frequency detecting means for detecting the predetermined frequency signal included in the broadcasting signal, sensing means for detecting a viewer around a television, and broadcasting. Image data storage means for storing one frame of the image signal detected from the signal, and selectively switching the output image signal read out from the image data storage means and the image signal detected from the broadcast signal to the image processing means. Outputting switching means to the frequency detecting means When a predetermined detection signal is applied from the sensing means while the predetermined frequency signal is detected, the video signal is stored in the image data storage means, and the image stored in the image data storage means through the switching means. It characterized in that it comprises a control means for controlling the output of the signal.

Claims

In a broadcasting system in which a predetermined frequency signal is added and transmitted to a broadcast signal containing text information, frequency broadcasting means for detecting the predetermined frequency signal included in the broadcast signal and a viewer around the television. Detecting means for storing the image signal for storing one frame of the image signal detected from the broadcast signal, and selectively outputting the output image signal read out from the image data storage means and the image signal detected from the broadcast signal. A switching means for switching and outputting the image signal to the image processing means, and when the predetermined detection signal is applied from the sensing means while the predetermined frequency signal is detected by the frequency detecting means Storing and storing the image data through the switching means. And a control means for outputting and controlling the video signal stored in the means.

The television receiver with a still picture output function according to claim 1, further comprising selecting means for selecting to cancel the still picture output.

The television receiver with a still picture output function according to claim 1 or 2, wherein the output state of the still picture continues until the still picture output function is released by said selecting means.

※ Note: The disclosure is based on the initial application.
