Abstract
비디오 카세트 레코더 또는 칼라텔레비젼의 체널선국시 비디오를 뮤팅하기 위한 방법이 기술되는바, 이는 비디오 뮤트포트를 따로 두지 않고 화상제어에 관련된 PWM포트를 로우로 함으로써 비디오 뮤트를 할수 있게된다.A method for muting video during channel tuning of a video cassette recorder or color television is described, which allows video muting by lowering the PWM port related to image control without leaving the video mute port aside.
