Display Mode diagram:

1. Picture in Picture mode

With a certain screen as the background, the signals of other windows are displayed in open window tiles.


2. Overlay mode

With the screen of a certain channel as the background, when the screens of other channels are displayed, the window and the window are partially or completely covered, and the covered part is not displayed.


3.Picture outside picture tile mode

Multi-channel or partial signals are displayed in full screen or non-full screen in any rectangular display format, and up to 8 windows can be opened on a single screen.


4. Scale and shift

The size and position of the window can be adjusted arbitrarily.


5. Image edge masking technology

Traditional splicing technology, when encountering edged display devices (such as rear projection, flat-panel TV, LCD/PDP or DLP, CRT and other display devices with borders), and when image are spliced and displayed after split, The adjacent two sets of display devices are divided due to the existence of undeveloped edges, resulting in unnatural distortion of the picture.Through fine pixel adjustment, the edge signal is automatically expanded, and the part of the content covered by the edge of the displayed device is shielded to achieve a natural and intuitive display effect. When debugging, the user only needs to input the size and size of the display unit in the control software. The approximate width of the black border of the edge, the technology will automatically calculate the range that needs to be masked to cover it.
