6.30 Calibrating a ClickShare Link
About c alibration
In the c ontext of Apple TV combined with the Link frame grabber, calibration is the procedure of detecting and determining a refer-
ence image. This is used by the A uto Show/Hide function : W hen the output image of the ClickShare Link m atches the reference
image the output of the ClickShar e Link is hidden.
The ClickShare Link will typically be calibrated on the Apple TV home screen.
The calibration will analyze the image during a 20 second time span. Only parts of the image that do not change during this period
will be used. This allows the algorithm to cope with the different appe arances of the hom e sc reen ( e.g. Com puters or Settings
selected) and the transients between them.
If for some reason calibration fails the previous reference image will be restored.
How to calibrate
1. Log in t o the ClickShare web interface.
2. Click the Maintenance tab (1) and then click Links (2 ).
