Abstract
Disclosed is a multiple video signals coexisting system and method thereof. The multiple video signals coexisting system includes a second switch and a first switch. The first switch outputs a portion of a first video signal and a portion of a second video signal from a plurality of video signals alternately as multiple coexisting video signals according to a selecting signal. The second switch generates the selecting signal according a toggle signal. The multiple video signals coexisting system further includes a pixel clock generator to generate a pixel clock and the second switch can employ the pixel clock to generate the selecting signal thereafter. The multiple video signals coexisting system outputs the multiple coexisting video signals for constituting continuous frames on a display, therefore, to show plural pictures on single display, and more particularly, to show an on-screen display menu translucently on the display.
