"Vu00ecdeo automatic switching system, method for automatic selection of a source of vu00ecdeo among multiple sources of vu00ecdeo disponu00ecveis, and.Apparatus comprising a medium that can be read by computer containing instructions for the computer.Methods and apparatus are described for automatic selection of a video output among various sources of video input.In one method, one or more sensors are associated with each input source of the video.Preferably, an audio sensor is positioned to receive audio signals from directions that receive favorable coverage in the field of view of the video source associated with it.A selector automatically calculates the markings of audio for each of the audio sensors through examination short intervals (for example, 0.5 seconds).In each interval of the examination, there is the potential for a different video source is selected as a video output.The selector automatically selects a video source based on the audio markers for a range of examination, in addition to the history of time recent selection of video source.For example, if a new video source has been newly selected, the selection of a different source may be disabled for a few seconds.The history of time is also used to increase the probability of selection of the source vary in a natural way.
