Abstract

본 발명은, 통신에 있어서 유용한 통신데이타가 무단으로 이용되는 것을 회피한다. 또, 통신속도가 다른 복수의 수신단말이 호스트컴퓨터에 동시 접속되었을때에, 통신속도를 일치시켜서, 동기 타이밍을 취한다. 장치는 통신회선으로 접속되고, 호스트컴퓨터로부터 각 수신단말에 대해서는, 일방향통신에 의해 부호화된 데이타 본체를 사이클방식으로 송신하는 한편, 상기한 호스트컴퓨터와 각 수신단말과는 쌍방향통신망으로 접속되며, 각 수신단말로부터의 개별요구에 따라 상기한 호스트컴퓨터로부터 상기한 부호화를 복호하는 스크램블데이타와, 데이타 본체를 실행하는 로우더를 다운로우드한다. 호스트컴퓨터는 각 수신단말이 설정하는 통신수단중, 가장 느닐 통신수단을 보유하는 통신수단를 구비하는 수신단말을 특정해서, 상기한 호스트컴퓨터에 동시에 접속하고 있는 복수의 수신단말의 통신속도를 상기한 가장 느린 통신속도에 일치시킨다.

Claims (8)

  1. 호스트컴퓨터(1)와 복수의 수신단말로(2)…(2)로 이루어지며, 이 호스트컴퓨터(1)로부터 각 수신단말(2)…(2)에 대해서는, 일방향 통신에 의해 부호화된 데이타본체를 사이클방식으로 송신하는 한편, 상기한 호스트컴퓨터와 각 수신단말과는 쌍방향 통신망으로 접속되어서, 각 수신단말로부터의 개별요구에 따라서 호스트컴퓨터로부터 상기한 부호화를 복호하는 스크램블데이터(11)와, 데이터본체를 실행하는 로우더(10)을 다운로우드하는 것을 특징으로 한 통신장치.
  2. 제1항에 있어서, 상기한 각 수신단말에서는, 상기한 데이타본체와, 상기한 스크램블데이타와, 상기한 로우더를 외부기억장치(8)에 일단 격납하고, 상기한 주기억장치(9)의 빈영역에 상기한 로우더와 상기한 스크램블데이타를 이행해서, 상기한 스크램블데이타를 참조하여 상기한 로우더가 상기한 데이타본체를 전개하는 통신장치.
  3. 제1항에 있어서, 일방향통신은 위성통신(3)인 통신장치.
  4. 제1항에 있어서, 쌍방향통신은 공중회선망(4)인 통신장치.
  5. 제1항에 있어서,쌍방향통신은 대화형 CATV네트워크(5)인 통신장치.
  6. 호스트컴퓨터(21)과 복수의 수신단말(22)…(22)을 공중회선으로 접속하는 네트워크(23)에 있어서, 상기한 호스트컴퓨터는 수신단말이 설정하는 통신수단 중, 가장 느린 통신속도를 보유하는 통신수단을 구비한 수신단말을 특정해서, 상기한 호스트컴퓨터에 동시에 접속하고 있는 복수의 수신단말의 통신속도를 상기한 가장 느린 통신속도에 일치시키는 통신장치.
  7. 제6항에 있어서, 새롭게 접속한 수신단말이 설정하는 통신수단의 통신속도를 판정하고, 상기한 호스트컴퓨터와 상기한 복수의 수신단말 사이에서 현재 설정되어 있는 통신속도와 비교해서, 낮은쪽의 통신속도에 모든 수신단말의 통신속도를 설정하는 통신장치.
  8. 제6항에 있어서, 상기한 통신수단은 모뎀인 통신장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
