Description

티브이의 비데오신호 입력시 자동음량 조절방법Automatic volume control method for video signal input of TV

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

제1도는 본 발명의 티브이의 자동음량 조절에 대한 전체 구성도, 제2도는 본 발명 롬내의 데이타에 대한 개략도, 제3도는 본 발명 티브이의 자동음량 조절에 대한 신호 흐름도.1 is an overall configuration diagram for the automatic volume control of the TV of the present invention, Figure 2 is a schematic diagram of the data in the ROM of the present invention, Figure 3 is a signal flow chart for the automatic volume control of the TV of the present invention.

Claims (1)

티브이/비데오 절환스위치(S1)의 절환신호(S1)에 의해 비데오(2) 및 중간주파 처리부(4)의 음성신호(S4)를 절환하여 중간주파 처리부(4)에 음성신호(S5)로 전송하는 스위칭 소자(3)와, 상기 스위칭신호(S1)에 의해 처리신호(S2)를 발생하고, A/D 변환기(12)를 통해 데이타(V1)를 수용하여 롬(9)의 데이타(Ds)와 비교후 기준 출력(C4)을 발생하고, 비교출력(V4)의 수용으로 제어출력(C1-C3)을 발생하는 마이콤(10)과, 출력레벨 검출기(7)를 통한 상기 중간주파 처리부(4)의 음성출력(S3)의, 레벨 D/A 변환기(13)를 통한 기준출(C4)의 레벨(V2)을 비교하여 비교출력(V4)을 발생하는 감산기(8)와, 상기 제어출력(C1)(C2) 수용하여 D/A 변환기(14)를 통한 제어출력(C3)과 함께 상기 중간주파 처리부(4)에 음성출력을 제공하는 볼륨제어기(11)로 구성하여, 처리신호(S2)의 고전위 상태인 비데오 상태로의 절환시에는 음성데이타(V1)를 읽어 저장한 후 레벨에 맞는 음성레벨을 선택하여 기준출력(C4)을 발생하고, 비교출력(V4)에 0보다 크면 볼륨다운에 대한 제어출력(C1)을 발생하며 0보다 작으면 볼륨업에 대한 제어출력(C2)을 발생하며 0으로 되면 완료하고, 처리신호(S2)의 저전위 상태인 티브이 상태로의 절환시에는 미리 저장된 티브이의 볼륨을 읽고, 티브이에서의 볼륨을 읽은 후 비교하여 같으면 완료하고, 다르면 미리 저장된 데이타에 대한 제어신호(C3)를 출력하는 것을 특징으로 하는 티브이의 비데오신호 입력시 자동음량 조절방법.The audio signal S4 of the video 2 and the intermediate frequency processor 4 is switched by the switching signal S1 of the TV / video switching switch S1 and transmitted to the intermediate frequency processor 4 as the voice signal S5. The processing element S2 is generated by the switching element 3 and the switching signal S1, the data V1 is received through the A / D converter 12, and the data Ds of the ROM 9 is received. The micro-frequency processing unit 4 generates a reference output C4 after comparison with the microcomputer 10 and generates a control output C1-C3 by receiving the comparison output V4, and the intermediate frequency processor 4 through the output level detector 7. A subtractor 8 for comparing the level V2 of the reference output C4 through the level D / A converter 13 of the audio output S3 of the " And a volume controller 11 which receives the C1) (C2) and provides a voice output to the intermediate frequency processor 4 together with the control output C3 through the D / A converter 14, and the processing signal S2. High state of video At the time of switching, the voice data (V1) is read and stored, and the voice level suitable for the level is selected to generate the reference output (C4). If the comparison output (V4) is greater than 0, the control output (C1) for volume down is applied. If it is less than 0, the control output C2 for volume up is generated. If it is 0, the control output C2 is completed. When the control signal S2 is switched to a low-potential TV state, the volume of the pre-stored TV is read. Read and compare the volume at and if the same is complete, if different, the automatic volume control method for inputting a video signal of the TV, characterized in that for outputting a control signal (C3) for the pre-stored data. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
