Abstract

[목 적][purpose]

본 발명은 위성수신기 데코더에 관한 것으로, 스크램블된 화상 및 음성신호의 수신 데이터가 위성수신기에 인가되면 데코더가 존재하는 지를 감지하여서, 스크램블된 수신 데이터를 자동적으로 데코더에 선택되도록 하는 자동 데코더 선택기능을 가진 위성수신기 데코더에 관한 것이다.The present invention relates to a satellite receiver decoder, and when the received data of the scrambled video and audio signal is applied to the satellite receiver to detect the presence of a decoder, an automatic decoder selection function to automatically select the scrambled received data to the decoder. The present invention relates to a satellite receiver decoder.

[구 성][Configuration]

본 발명은 TV5와 위성 수신기(60)를 연결하는 연결부(10)와; 데코더(30)의 E단에 저항(R1)이 연결되고, 저항(R1)에 병렬연결되어 접지된 저항(R2)으로 구성된 감지수단(7)과, 상기 감지수단(70)의 저항(R1)(R2)의 사이가 제어부(40)와 연결되어서 제어부(40)의 제어에 의하여 데코더(30)를 A단으로 연결하도록 하거나 또는 안테나에서 위성 수신기(60)의 회로부(50)을 통하여 수신되는 수신 데이터를 B단으로 연결하도록 스위칭하는 스위칭부(20)로 구성된다.The present invention provides a connection unit 10 for connecting the TV5 and the satellite receiver 60; A resistor R1 is connected to the E terminal of the decoder 30, and the sensing means 7 comprises a resistor R2 connected in parallel to the resistor R1 and grounded, and the resistor R1 of the sensing means 70. (R2) is connected to the control unit 40 to connect the decoder 30 to the A stage under the control of the control unit 40 or the reception received through the circuit unit 50 of the satellite receiver 60 at the antenna It consists of a switching unit 20 for switching to connect the data to the B stage.
