Abstract

본 발명은 텔레비젼의 두화면시청시 음성출력모드 표시장치에 관한 것으로, 특히 텔레비젼수상기로 소정의 두화면모드로 시청중에 동일한 방송모드로 출력되는 방송에 대하여 OSD로 어느쪽이 주화면인지 부화면인지를 표시함으로서 시청자의 편의를 도모한 텔레비젼의 두화면시청시 음성출력모드 표시장치에 관한 것이다.The present invention relates to an audio output mode display apparatus for watching a two-screen of a television, and in particular, whether the main screen or the sub-screen is displayed on an OSD for a broadcast output in the same broadcast mode while watching a predetermined two-screen mode on a television receiver. The present invention relates to an audio output mode display apparatus for viewing a two-screen of a television for the convenience of a viewer by displaying.

즉, 주화면과 부화면으로부터 출력되는 음성을 분리하여 출력하는 D/A변환부(130)와, 상기 D/A변환부(130)에서 출력된 음성신호를 증폭하는 스피커(150)로 출력하는 제1 및 제2음성증폭부(140)(160)와, 상기 제2음성증폭부(160)로부터 증폭된 음성신호를 적외선신호로 변환하여 헤드폰(180)으로 출력하는 신호처리부(170)와, 상기 주신호처리부(10)와 두화면/PIP처리모듈부(20)에서 처리하는 음성신호의 방송종류를 인식하는 방송종류인식부(120)와, 상기 방송종류인식부(120)에서 인식된 신호로 제어신호를 출력하는 주제어부(100)와, 상기 주제어부(100)의 제어신호로 주신호처리부(10)의 믹서(12)를 통해 CRT(17)상에 소정의 문자정보를 출력하는 OSD발생부(110)를 구성하여 시청자의 편의증대와 텔레비젼의 기능을 향상시킨 것이다.That is, the D / A converter 130 separates and outputs the voice output from the main screen and the sub-screen, and outputs the speaker 150 to amplify the voice signal output from the D / A converter 130. A first and second voice amplifiers 140 and 160, a signal processor 170 for converting the amplified voice signal from the second voice amplifier 160 into an infrared signal and outputting the infrared signal to the headphones 180; The broadcast type recognition unit 120 for recognizing the broadcast type of the voice signal processed by the main signal processing unit 10 and the two screen / PIP processing module unit 20, and the signal recognized by the broadcast type recognition unit 120. OSD to output the predetermined character information on the CRT 17 through the main control unit 100 for outputting a control signal to the control signal of the main control unit 10 and the mixer 12 of the main signal processing unit 10 as a control signal of the main control unit 100. The generation unit 110 is configured to increase the convenience of the viewer and improve the function of the television.
