deal of control over the settings if you wish.

The Presets section contains up to sixteen different settings, plus the factory setting. If a number is highlighted, then that preset has been programmed with valid settings and may be used. Note that the Factory preset is always available. Simply click on the appropriate button and those settings will be restored.

To save settings to a preset, click on the Save->Presetbutton in the Actions pane. The preset buttons will highlight. Click the desired preset button to save the values. Note that any previous settings assigned to that button will be lost. If you do not wish to save the presets after clicking the Save->Presetbutton, click the Save->Presetbutton a second time and the save function will be cancelled.

The section of the screen marked Current Values indicates the various video parameters that can be adjusted. For each parameter, there are a series of buttons: [, <<, -, Auto, +, >, ]. The ’[’ and ’]’ buttons set the parameter to its smallest or largest values, respectively. The ’<<’ and ’>>’ buttons decrease or increase the parameter by a large amount. In the case of phase, this is 4 units. For all the others, this is 10 units. The ’-’ and ’+’ buttons decrease or increase the parameter by one unit. The middle button sets the parameter to the middle value. The text of the middle button also indicates which parameter is being controlled. Note that in the case of phase, the middle button invokes the auto-phase algorithm.

The Performance section of the screen gives an indication of the quality of the video. Changes/frame is the average number of tiles that change for each frame sampled by the hardware. Flatness is an indication of what percentage of the screen contains tiles that are comprised of only one color.

The Regrab Screen button in the Actions section causes the screen to be re-captured. When making small changes to the video parameters, sometimes these changes are not reflected in the displayed screen immediately, particularly if the noise filter is enabled.

Press this button to see the immediate effect of the changes.

Use the Show Diffs button to learn which parts of the screen are being sent over the Internet. When you click this button, the screen is cleared to a medium grey color. All blocks that are sent from that point on will show up on the screen as they are sent. Click the button again to reset the screen to grey. To return to normal operation, click the Regrab button. It is very easy to visually identify the effect noise has on signal processing, using this feature.

The Auto Offset & Gain button in the Actions section invokes the automatic algorithm for setting the video parameters. The algorithm requires the factory calibration test pattern to be correctly displayed on the screen.
