Abstract

본 발명은 티브이 음성자동 조절방법에 관한 것으로, 방송국에 따라 음성변조도가 다르면 재생되는 소리의 크기가 달라지므로 이를 자동으로 보상해 주는 것을 기술적 과제로 하며 선택된 채널에서 검파된 음성레벨을 검출하여 이 값을 마이콤에 기억시키고 절환된 채널의 검파된 음성신호레벨을 검출하여 절환되기전의 검파된 음성레벨과 비교하여 차이가 나면 그 차이만큼 볼륨량을 변하시켜 보상해 주는 것을 요지로 한다.The present invention relates to a TV voice automatic control method, and if the voice modulation is different according to the broadcasting station, the volume of the reproduced sound is different, so that the technical task of automatically compensating for this is detected by detecting the detected voice level in the selected channel Is stored in the microcomputer, the detected voice signal level of the switched channel is detected and compared with the detected voice level before switching, and if there is a difference, the volume is changed to compensate for the difference.

따라서 티브이 시스템에 적용함으로써 시청자가 채널변경시 볼륨량을 제조정하는 불편함이 없이 시청할 수 있는 효과가 있다.Therefore, by applying to the TV system, there is an effect that the viewer can watch without the inconvenience of manufacturing the volume amount when changing the channel.

Claims (1)

사용자가 선택한 볼륨값을 읽어 레지스터(A)에 저장하고, 검파된 음성신호의 피크레벨값을 읽어 레제스터(B)에 저장한 다음 채널변경시엔 변경된 음성신호의 피크레벨값을 읽어 레지스터(C)에 저장하여 상기 볼륨값이 채널변경전과 같으면 볼륨을 보상하기 위하여 채널변경전 피크레벨과 채널변경후 피크레벨의 차이를 검출한 뒤 채널변경전볼륨(A) ×채널변경전피크레벨(B) ÷채널변경후 피크레벨(C)로 연산하여 볼륨을 보상함을 특징으로 하는 티브이 음성자동 조절방법.The volume value selected by the user is read and stored in the register A. The peak level value of the detected audio signal is read and stored in the register B. When the channel is changed, the peak level value of the changed audio signal is read and the register C is read. If the volume value is the same as before the channel change, the difference between the peak level before the channel change and the peak level after the channel change is detected to compensate for the volume, and then the volume before the channel change (A) × the peak level before the channel change (B) ÷ TV voice automatic adjustment method characterized in that the volume is compensated by calculating the peak level (C) after changing the channel. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
