Abstract

본 발명은 텔레비전 방송신호와 케이블 방송 신호를 복원하는 컨버터를 하나의 통합된 송신기를 이용하여 제어하는 장치에 관한 것으로서, 케이블 방송을 수신할 수 있는 모드에서 상기 송신기로부터 지령된 명령에 의해 케이블 컨버터에서 인식할 수 있는 IR 코드를 데이터로 출력하고, 동시에 해당하는 반송 주파수를 출력하는 마스터 마이크로프로세서; 상기 마스터 마이크로프로세서로부터 출력된 방송 주파수와 해당 데이터를 조합하는 NAND게이트; 상기 NAND게이트로부터 출력된 신호에 따라 도통 및 절연되는 트랜지스터; 및 상기 트랜지스터의 도통상태의 출력신호를 인식하여 스크램블된 케이블 방송신호로 복원시키는 케이블 컨버터를 구비한다.The present invention relates to an apparatus for controlling a converter for recovering a television broadcast signal and a cable broadcast signal by using a single integrated transmitter. The present invention relates to a cable converter in which a cable broadcast is received by a command commanded from the transmitter. A master microprocessor which outputs a recognizable IR code as data and simultaneously outputs a corresponding carrier frequency; A NAND gate combining a broadcast frequency output from the master microprocessor and corresponding data; A transistor electrically conductive and insulated according to a signal output from the NAND gate; And a cable converter that recognizes the output signal of the conduction state of the transistor and restores the scrambled cable broadcast signal.

상술한 바와 같이 본 발명에 따른 텔레비전 방송신호와 케이블 방송신호를 하나의 통합된 송신기로 제어하는 장치는 하나의 송신기를 이용하여 텔레비전 방송신호와 케이블 방송신호를 수신할 수 있는 케이블 컨버터를 동시에 컨트롤할 수 있으므로써 송신기 사용의 간편함과 편리함을 제공한다.As described above, an apparatus for controlling a television broadcast signal and a cable broadcast signal according to the present invention by using a single transmitter may simultaneously control a cable converter capable of receiving a television broadcast signal and a cable broadcast signal using a single transmitter. This provides the simplicity and convenience of using the transmitter.
