Abstract

본 발명은 위성방송시스템의 송ㆍ수신장치에 관한 것으로, 특히 전원오프시 전송되는 데이타를 검출하기 위한 관련회로만을 주기적으로 동작시켜 검출하는 위성방송시스템의 스마트카드를 이용한 데이타 송수신장치에 관한 것이다. 종래에는 전원 오프시 위성방송을 통해 스마트카드데이타 요구등과 같은 신호가 전송될 때, 항상 위성수신기에 전원을 공급되어져야만 위성신호 검출할 수 있었다. 그러나, 본 발명은 위성방송수신기에 전부 전원을 공급하지 않고, 수신되는 데이타를 검출하기 위한 관련회로만을 주기적으로 동작시켜 스마트카드데이타를 검출하므로써 불필요한 전력소모를 막는 잇점을 제공한다.The present invention relates to a transmission and reception apparatus of a satellite broadcasting system, and more particularly, to a data transmission and reception apparatus using a smart card of a satellite broadcasting system that periodically operates and detects only a related circuit for detecting data transmitted when a power is turned off. Conventionally, when a signal such as a smart card data request is transmitted through a satellite broadcast when power is off, the satellite signal can be detected only when the satellite receiver is always powered. However, the present invention provides an advantage of preventing unnecessary power consumption by detecting smart card data by periodically operating only an associated circuit for detecting received data without supplying power to the satellite broadcasting receiver.
