The above example shows that the “H Total” is the sum of the horizontal pixels of the various LED walls; the “V Total” is the sum of the vertical pixels of the various LED walls; these two parameters are the same in the various processors. The Horizontal Total

20 /26

Pixels and Vertical Total Pixels form a coordinate plane with pixel as scale. The processor sets the desired parameters “H Start” and “V Start” according to the coordinate plane.

PIP

The PIP function includes the Picture-in-Picture mode and KEY mode. When the function is turned on, the “Seamless Switching” function will be turned off automatically.

PIP Mode

The PIP mode is Picture-in-Picture that uses the digital technology to display two programs on the same screen, that is, on the main screen being watched normally, one or more compressed sub-screens are inserted, so that the user can monitor other channels while watching the main screen. In the PIP mode, the user needs to provide at least two channels of signal input and set the PIP menu accordingly. Before using the PIP function, the user should understand the Source Input Conflict List.

Keying Mode

Keying is the extension of the PIP function. It is realized by reducing the specified colors from the picture colors of the PIP channel input. The Keying function can be used in some simple special effect processing and caption adding. The setup operation is simple.

Refer to the setup example:

Enter the Keying menu: In the main menu, select “PIP” → “Keying” → Parameter

Setup, set the “Input” to “VGA” and the “Chroma Key” to “Black”. Tip: Here, the

“Chroma Key” refers to the colors extracted, including blue, green, red, and black.

Caption Effect

The above figure shows that the PIP channel input is a picture of white text in the blue background, and when the two pictures are overlaid and the blue color is removed, the caption effect is realized.

Seamless Switch

The Seamless Switch is an effect realized when the main channel is switched. This effect allows the audience to watch pictures smoothly and comfortably when watching video being switched. When the PIP function is activated, the picture switching effect function can’t be used. To use this function, disable the PIP function first. (The PIP function can be disabled in the main menu or with the “PIP” shortcut key.)

Seamless Switch has two effects, i.e. “CUT” and “FADE”. “CUT” is instant Seamless, and “FADE” is fade-in fade-out. The time of fade-in fade-out can be set in the main menu, select “FUNC” → “Fade Time” → Parameter Setup.

Test Pattern

After the LED wall is installed, you may need to use the test pattern to inspect whether the LED wall is normal. The video processor provides a number of test patterns for you to test whether the LED wall has any defective pixel or blind spot and whether the

LED wall lattice is aligned. You may make adjustment through the following operations.

test pattern output: On the Front Panel, press “TEST” to output the current pattern; press

“TEST” again and use the direction keys to select different test pattern.

Preset Mode

In the preset mode, you can quickly invoke various frequently used application scenarios during use to reduce repeated, complex setup, thus improves the efficiency of operations. Each preset mode includes such parameters as signal channel mode, displaying

23 /26

mode, picture quality setup, etc. The saving and invocation of the preset mode are described below.

Saving of preset mode: In the main menu, select “FUNC” → “Preset” → “Save
