Instruction manual

buttons decrease or increase the parameter by a large amount. In the

case of phase, this is four units and for all others, ten 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 indicates 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 reﬂ ected in the displayed screen

immediately, particularly if the noise ﬁ lter 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.

Disk Control Menu

Aside from status information, there are only three buttons in this window.

Insert will simulate the insertion of a disk, while USB Replug can be used

to force the host to recognize the “inserted” disk (not required unless the

host OS or hardware does not recognize it automatically.

Please note that only one option is enabled at any time, based on the

current state of the emulated disk.
