Claims (3)
- 통신 가능한 모뎀이 장착된 위성방송수신기의 프로그램수신 방법에 있어서, 상기 수신기의 메모리에 기설정된 가입자암호에 근거하여 외부로부터 인가되는 가입자암호가 올바른 암호인자를 판단하는 상기 가입자식별단계 ; 및 상기 가입자식별단계에서 올바른 암호가 입력되었을 때에만 상기 모뎀을 통해 필요한 프로그램을 제공하는 서비스센터와 접속하여 원하는 프로그램을 다운받아 메모리에 저장하는 프로그램다운로드단계를 포함하는 모뎀을 이용한 위성방송수신기의 프로그램수신방법.
- 위성방송수신기의 프로그램수신장치에 있어서, 다수의 프로그램을 제공하는 서비스센터와 접속하여 기설정된 다운방식에 따라 필요한 프로그램을 다운받을 수 있는 모뎀; 가입자암호를 기저장하고 있으며, 상기 모뎀을 통하여 다운받은 새로운 프로그램을 소정의 프로그램영역에 저장하는 메모리 ; 및 상기 메모리에 기설정된 가입자암호에 근거하여 외부로부터 인가되는 가입자암호가 올바른 암호인지를 판단하고, 올바른 암호일때만 기설정된 다운방식에 따라 필요한 프로그램을 다운받도록 제어신호를 출력하고, 상기 프로그램이 상기 메모리에 저장되도록 제어신호를 출력하고, 상기 프로그램의 다운이 완료되면, 메모리에 저장된 프로그램을 실행하여 수신기의 프로그램을 수정하는 제어부를 포함하는 통신 가능한 모뎀이 장착된 위성방송수신기의 프로그램수신장치.
- 제 2 항에 있어서, 상기 메모리는 상기 모뎀을 통해 서비스센터에서 제공하는 다수의 새로운 프로그램을 인가받기 위해 새로운 프로그램의 저장과 기존의 프로그램 삭제가 가능한 읽기/쓰기 메모리인 것을 특징으로 하는 통신 가능한 모뎀이 장착된 위성방송수신기의 프로그램수신장치.
