Abstract

본 발명은 대화형 텔레비젼수상기(1TV)의 통신을 보호하는 기술에 관한 것으로, 하나의 전화선로에 필요에 따라 전화기를 연결하여 사용하거나 대화형 텔레비젼 수상기를 연결하여 사용하는 시스템에서 이미 대화형 텔레비젼 수상기를 사용하고있는 상태에서 다른 사용자가 그 사실을 모르고 전화기를 사용하려고 하는 경우 전화기의 수화기를 통해 음성 안내메시지를 출력하고, 외부로 부터 전화가 걸려오는 경우 화면상에 그 사실을 알리는 메시지를 출력하도록 하였다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technology for protecting communication of an interactive television receiver (1TV). The present invention relates to an interactive television receiver in a system using a telephone or an interactive television receiver connected to one telephone line as necessary. If you are using and you do not know the fact that you want to use the phone to output a voice prompt message through the handset of the phone, and if the call from the outside to output a message informing the fact on the screen It was.
