A Pictorial View of a MultiCam System
This drawing shows three channels, numbered #1, #2 and #3.
The channel #1 realizes an acquisition path from the camera #1 to the cluster #1. This channel appropriates the grabber #1 for its sole usage. Consequently, the channel #1 can operate in a concurrent fashion, without interfering with the other channels.
The channel #2 realizes an acquisition path from the camera #2 to the cluster #2. The channel #3 realizes an acquisition path from the camera #3 to the cluster #3.
This pair of channels needs the grabber #2 for operation, as only two grabbers are available in the frame grabber. This means that the grabber #2 is a shared resource, and channels #2 and #3 will operate in a switched fashion.
