Abstract

본 발명은 비디오폰 내장형 티브이 시스템에 관한 것으로, 종래에는 비디오폰의 2화면 티브이를 각각 구입한 후 비디오 라인으로 연결하여야만 비디오폰의 송.수신화면을 2화면 티브이에 디스플레이 가능하므로 시스템 자체의 비용이 많이드는 문제점이 있었다.The present invention relates to a video phone built-in TV system, and in the related art, it is necessary to purchase two video screens of a video phone and connect them to a video line so that the cost of the system itself can be displayed on the two-screen TV. There was a lot of trouble.

따라서, 종래의 문제점을 해결하기 위하여 본 발명은 PiP(Picture in Picture)기능을 갖는 티브이회로에 비디오폰 기능을 갖는 회로를 추가 구성하여 티브이 신호나 카메라 신호를 원하는 상대방에게 선택하여 전송할 수 있도록 함과 아울러 두개의 시스템의 하나의 시스템으로 구성함으로써 가격측면에서 유리하도록 한 효과가 있다.Accordingly, in order to solve the conventional problem, the present invention further comprises a circuit having a video phone function in a TV circuit having a picture in picture (PIP) function so that a TV signal or a camera signal can be selected and transmitted to a desired counterpart. In addition, there is an effect that it is advantageous in terms of price by configuring one system of two systems.
