Abstract
A method and system for notifying a viewer of the arrival or presence of one or more video input signals in a video display system, such as a personal computer (PC) or television (TV) system. If a video signal is already present, the system may optionally notify a viewer of the termination or absence of the video signal. The invention further provides the viewer with the opportunity to dynamically select the video source to view. Upon sensing the presence of a new video signal, the system alerts the viewer who may then select whether to view the new video signal or maintain prior viewing status.
