Abstract

본 발명은 텔레비젼의 음성절환장치에 관한 것으로서, 그 구성은 텔레비젼의 스피커(SP)를 통하여 시청자에게 제공되는 방송음성신호의 출력경로를 전화기(40)의 통화신호처리수단(42)측으로 선택 절환하기 위한 음성절환수단(24)과, 상대 통화자와의 통화신호를 국선으로부터 검출토록 하는 통화 신호검출수단(26), 음성절환모드의 설정을 위한 음성절환키(28e)를 구비하고 있는 키입력수단(28) 및, 텔레비젼의 전체기능을 제어하며 상기 키입력수단(28)을 통한 음성절환모드의 설정유.무 및 상기 통화신호검출수단(26)에서의 통화신호검출 유. 무에 의거하여, 전화기의 음성 송/수신 기능을 이용하여 텔레비젼에서 방송중인 중요한 내용 등의 방송음성을 상대통화자에게 송출할 수 있도록 하여 주는 효과가 있다.The present invention relates to an audio switching device for a television, the configuration of which selects and switches the output path of a broadcast audio signal provided to a viewer through a speaker (SP) of the television to the call signal processing means 42 of the telephone 40. Key input means provided with a voice switching means 24 for receiving the voice signal, a call signal detecting means 26 for detecting a call signal with the other party from the trunk line, and a voice switching key 28e for setting the voice switching mode. And (28), the presence or absence of setting of the audio switching mode via the key input means (28), and the call signal detection means in the call signal detection means (26). Based on nothing, there is an effect of making it possible to transmit a broadcast voice of important contents being broadcast on a television to the other party by using the voice transmission / reception function of the telephone.

Claims

An image signal processing system including an image IF module 14, an image signal processing means 18, and an image signal output means 22 for processing an image signal included in a broadcast signal tuned to the tuner 10 and its broadcasting. A voice signal processing system including a voice IF module 12 for processing a voice signal included in the signal, a voice signal processing means 16, and a voice signal output means 20 is provided for the image / video on the CRT and speaker SP. Voice switching means for selectively switching the output path of the broadcast voice signal provided to the viewer through the speaker SP of the television to the call signal processing means 42 side of the telephone 40 in the television performing the voice broadcast signal reproduction. A key input means 28 including a call signal detecting means 26 for detecting a call signal with a counterpart call from a trunk line, a voice switching key 28e for setting a voice disease mode, and Control the full functionality of the TV, The audio output path of the voice switching means 24 is controlled based on whether or not the voice switching mode is set through the key input means 28 and whether or not the voice signal is detected by the call signal detecting means 26. A sound switching device for a television comprising a control means (30).

The end switch 24a of claim 1, wherein the voice switching means 24 comprises an end gate 24a for logically multiplying the voice switching signal and / or the call signal applied from the control means 30, and the end gate 24a. Call signal processing of the telephone 40 by amplifying the audio output signal of the television output through the switching transistor 24b and the switching transistor 24b that switches the path of the television audio output signal on and off based on the output signal. And amplifying means (24c) provided to the means (42) side.
