Claims (1)

훅스위치 상태감지기(58)에 의한 훅스위치 상태 감지에 의해 CPU(43)는 전원회로(59)를 구동하고 전송버턴(43)선택을 하여 카메라 영상 출력신호를 A/D변환하고, 타이밍 발생기(39)의 클럭 신호는 메모리 제어기(40)를 제어하여 A/D변환된 영상신호를 메모리(33)에 기억시키며, 변조기(34)와 증폭기(35)를 통해 변조증폭된 영상신호는 CPU(43)에 의해 제어되는 선택스위치(36)와 선택스위치(36)에 의해 선택된 BPF(37, 38)를 거쳐 인터페이스회로(44)로 인가되고, 전화회선(47)이 접속된 인터페이스회로(44)에서 수신되는 캐리어 판별을 위해 톤디코더(51, 52)의 출력을 CPU(53)가 판별 출력하여 선택스위치(36)를 제어하며, 상기 선택스위치(48)에 의해 선택되는 BPF(40, 50)의 출력신호는 수신증폭기(54)를 거쳐 CPU(5)의 제어에 따라 복조되고 D/A변환되어 모니터(57)상으로 음성·영상 출력을 동시에 전송가능하도록 구성한 것을 특징으로 하는 영상과 음성 동시 전송장치.By detecting the hookswitch state by the hookswitch state sensor 58, the CPU 43 drives the power supply circuit 59 and selects the transmission button 43 to A / D convert the camera image output signal, and generates a timing generator ( The clock signal 39 controls the memory controller 40 to store the A / D-converted video signal in the memory 33. The video signal modulated and amplified by the modulator 34 and the amplifier 35 is the CPU 43. In the interface circuit 44 connected to the interface circuit 44 via the selection switch 36 controlled by the control panel and the BPFs 37 and 38 selected by the selection switch 36, and the telephone line 47 is connected. The CPU 53 controls the selection switch 36 by outputting the tone decoders 51 and 52 to discriminate the received carrier, and selects the BPFs 40 and 50 selected by the selection switch 48. The output signal is demodulated under the control of the CPU 5 via the receiving amplifier 54 and D / A converted to output audio and video onto the monitor 57. The simultaneously transmitted audio and video broadcast apparatus, characterized in that configured to enable. ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
