Abstract: An intelligent audio/video source switcher and controller that automatically switches the input source based on a change in an incoming audio/video signal (for example, upon detection of a commercial break), devices that connect to the source switcher and controller, and methods for using the same, are presented. The switcher allows playback of media stored in memory of the switcher or streamed to the switcher via a network connection, thereby allowing commercial breaks in a television broadcast to be replaced with alternate content, such as alternate advertising or entertainment. In one or more embodiments, the apparatus of the present invention includes a control server configured to send commands to the switcher via a network to instruct the switcher to switch audio/video inputs, play back alternate media, or download media and/or software updates.
