Abstract
A plurality of digital cameras that are synchronized are connected to a switcher, thus constructing a digital monitoring system in which image signals from the cameras are switched and received. A method of switching the image signals includes the steps of setting transmission timings and transmission cycles of I frames from the digital cameras, buffering the image signals of one cycle from the cameras, and extracting necessary I frames from the buffered image signals. Even though the digital image signals include frames depending upon other frames such as P frame and B frame, the I frames are received by switching operation.
