Abstract
본 발명은 디지탈 DBS(Direct Broadcasting Satellite ;직접위성방송)의 제한수신 시스템(Conditional Access System)에 관한 것으로, 특히 디지탈 DBS의 송신 장치에서 제한수신 시스템을 분리시켜 다양한 운영이 가능하도록 한 디지탈 DBS의 분리형 제한수신 시스템에서 송신 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a Conditional Access System (DBS) of a digital DBS (Direct Broadcasting Satellite), and more particularly to a digital DBS To a transmitting apparatus in a conditional access system.
그런데, 종래에는 제한수신을 원하지 않는 경우에도 제한 수신을 위한 복잡한 동작을 수행하여야 하므로 번거로우며 해당 제한수신을 원하지 않는 송신 장치에 대한 비용만 상승시키는 문제점이 있다.However, in the prior art, even if the restricted reception is not desired, complicated operations for limited reception must be performed, which is cumbersome and raises the cost of a transmitting apparatus that does not want to receive the restricted reception.
본 발명에 의해 전송신호발생 블록과 제한수신 블록을 분리시켜 개별 제품으로 사용될 수 있게 함으로써, 제한수신을 원하지 않는 송신 장치는 제한수신 블록을 사용하지 않아 비용을 절감하고 개별 제품의 제한수신 블록으로 다양한 운영을 할 수가 있다.The transmission signal generation block and the conditional reception block can be separated and used as individual products, so that the transmission device that does not want to receive the restricted reception does not use the restricted reception block, I can operate it.
