Claims (2)

마이크로 컴퓨터(21)로부터 방송수신채널 데이터가 튜너와 복조기(22)에 입력되어 방송을 수신하도록 연결되고, 수신된 비데오신호가 A/D 변환기(24)를 통해 디지탈 신호로 변환되어 입출력단자(25)를 통해 기억억소자(29)에 기억되도록 연결되며, 기억소자(29)의 출력은 다시 입출력단자(25)를 통해 D/A 변환기(26,27)에서 아날로그신호로 변환되어 혼합기(28)에 인가되도록 연결되고, A/D 변환기(24), D/A 변환기(26,27), 입출력단자(25), 기억소자(29)와 혼합기(28)는 마이크로컴퓨터(21)에 연결된 디지털제어기(23)에 의해 제어를 받도록 연결되어지는 것을 특징으로 하는 2채널 수신시스템.The broadcast receiving channel data from the microcomputer 21 is input to the tuner and the demodulator 22 and connected to receive a broadcast. The received video signal is converted into a digital signal through the A / D converter 24 and the input / output terminal 25 The memory device 29 is connected to the memory storage device 29, and the output of the storage device 29 is converted into an analog signal from the D / A converters 26 and 27 through the input / output terminal 25, and then the mixer 28 is stored. A / D converter (24), D / A converter (26,27), input / output terminal (25), memory element (29) and mixer (28) are connected to the microcomputer (21). A two-channel receiving system characterized by being connected to be controlled by (23). 디지털 제어기와 마이크로 컴퓨터를 이용하여 하기의 스템(가-바)으로 제어되는 것을 특징으로 하는 2채널 수신시스템.A two-channel receiving system characterized by being controlled by the following stem (ga-bar) using a digital controller and a microcomputer. 가. 2화면 모드를 판단하여 2화면 모드가 되면 시간을 나타내는 레지스터(t)를 “O”으로 설정하고, 동시에 주화면 수신상태를 나타내는 출력레지스터(MAIN)를 “H”로 설정하며, 소화전 수신상태를 나타내는 출력레지스터(SUB)를 “L”로 설정하고, 채널을 표시하는 레지시터(CH)에 현재의 채널데이타(PRESENT CHANNEL DATA)를 설정하며, 나. 레지스터(t)의 값이 10이 아니면 레지스터(t)의 값이 “1”을 더하고, 다. 레지스터(t)의 값이 10이면, 레지스터(MAIN)를 “L”레지스터(SUB)를 “H”로 설정하고, 레지스터(CH)에 다음 방송이 있는 채널 데이터(NEXT CHANNEL DATA)를 설정하며, 라. 주화면 수신시 채널설정버튼(CH-UP, CH-DOWN)에 의하여 특정채널을 소화면으로 수신하도록 채널을 검색하여 소화면으로 설정된 채널(SELECTED CHANNEL)을 채널 레지스터(CH)에 설정하고, 마. 채널레지스터(CH)에 설정된 소화면용 채널데이타를 수신하기 위한 기간을 제어하도록 레지스터(C)의 값이 15인가를 검색하여 15가 아닐 경우에는 레지스터(t)값에 “1”을 더하며, 바. 레지스터(t)의 값이 15이면 상기한 스텝(가-마)을 반복한다.end. Judging from the two screen mode, when the display enters the two screen mode, set the register (t) indicating the time to "O", and simultaneously set the output register (MAIN) indicating the main screen reception status to "H", and set the hydrant reception status. Set the output register (SUB) to “L” and the current channel data (PRESENT CHANNEL DATA) to the register (CH) indicating the channel. If the value of register (t) is not 10, the value of register (t) adds "1". If the value of the register (t) is 10, set the register (MAIN) to the "L" register (SUB) to "H", and set the channel data (NEXT CHANNEL DATA) with the next broadcast in the register (CH). la. When receiving the main screen, use the channel setup button (CH-UP, CH-DOWN) to search the channel to receive a specific channel on the small screen, and set the channel (SELECTED CHANNEL) set to the small screen in the channel register (CH). . In order to control the period for receiving small screen channel data set in the channel register (CH), search whether the value of register (C) is 15. If not, add "1" to the value of register (t). bar. If the value of the register (t) is 15, the above step (ga-ma) is repeated. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
