Description

음성암호화장치가 구비된 유선티브이 시스템Streamlined system with voice encryption

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제 2 도는 본 발명에 의한 음성암호화 송신시스템과 수신시스템과의 개략블럭도, 제 3 도는 본 발명에 의한 수신시스템을 나타내는 회로블럭도.2 is a schematic block diagram of a voice encryption transmission system and a reception system according to the present invention, and FIG. 3 is a circuit block diagram showing a reception system according to the present invention.

Claims (1)

송신시스템(1) 및 수신시스템(2)에 각기 영상신호에 대한 암호화 및 해독회로를 구비시킨 것에 있어서, 상기 송신시스템(1)의 음성변조계통에는 음성변조기(11)의 입력에 믹서(12)를 두고 이 믹서(12)는 FM 변조된 입력과 이 FM 변조 입력의 진폭변조를 위해 소정주파수의 펄스파를 제공하는 스크램블링단(13)에서의 출력을 믹서하여 출력하는 구성의 음성 암호화부(10)가 포함된 송신시스템(1A)과, 상기 수신시스템(2)은 음성해독부(20)를 포함한 수신시스템(2A)으로되고, 이 음성해독부(20)는 영상해독부회로(22)의 타이밍 펄스회로(25)가 마이크로프로세서(27)로 가해지고, 이 마이크로프로세서(27)은 음성 IC(28)를 제어하는 볼륨제어 펄스를 송신시스템(1A)측에서의 진폭 변조분을 상쇄하는 볼륨제어펄스를 제공하는 구성으로 된 것을 특징으로 하는 음성암호화, 해독장치가 구비된 유선티브이 시스템.In the transmission system 1 and the reception system 2 having encryption and decryption circuits for the video signals, respectively, the audio modulation system of the transmission system 1 has a mixer 12 at the input of the audio modulator 11. The mixer 12 has a voice encryption unit 10 configured to mix and output an FM modulated input and an output from a scrambling stage 13 which provides pulse waves of a predetermined frequency for amplitude modulation of the FM modulated input. And a receiving system 2A including the audio decoding unit 20. The audio decoding unit 20 includes a video decoding unit 22. A timing pulse circuit 25 is applied to the microprocessor 27, and the microprocessor 27 controls the volume control pulse for controlling the voice IC 28 to cancel the amplitude modulation component on the transmission system 1A side. Voice encryption, decryption, characterized in that the configuration to provide The cable television system having value. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
