  • Video muting device for digital video signal and muting method therefor
    Patent number: 7755568
    Abstract: A video muting device for a digital video signal, and a video muting method thereof. The video muting device includes a scaler which determines according to a clock (CLK) signal of an inputted digital video signal whether a mode has changed, and generates an interrupt signal if the mode has changed, and a control part which generates a mute signal upon being input with the interrupt signal from the scaler. Accordingly, even when a digital signal, as well as an analog signal, is input, transient phenomena and noise generated during mode change can be effectively removed.
