HDMI video wall controller using application fields:

Main festures:

1. POP Picture Out Picture Mode: Multiple or part signals are displayed to full screen or part screen

in any rectangle shape, single panel can create 4 video windows at most.

Figure 2.2 POP Tile mode

2. Single screen can create 16 video windows at most: in the same whole screen, can set 4 CBD areas,

each CBD can open 4 windows, i.e. single screen can create 16 windows at most.

3. PIP mode: use certain one picture as background; the other video windows adopt tile mode.

4. Overlapping mode: use certain one channel as background, the other channels are also displaying

on the screen with the overlapping part invisible.

5.Scaling and Positioning: Size is scalable and position adjustable.

6. Edge shield technology: Under traditional splicing technology, when encountered with video wall

consisting of rear projector, Panel TV, LCD/PDP or DLP, CRT, as their pictures are spliced after being

divided and the adjacent displays cannot display the cutting edge because of the gaps, the overall picture

will become abnormal unnaturally.

Through refined pixel adjustment and the edge signal automatically extended, the edge covering part

is shielded to achieve a natural and intuitive viewing. During debugging, users only need to input in the

control software the size value of the display unit and the approximate width value of back edge,

it will automatically calculate the required shielding range and perform the mask with our unique techniques.

7. Edge fine-tuning technology: Make adjustment on single pixel of splicing screen edge through the

operation of the control software in order to reach seamless splicing. The technique is suitable for front projection,

rear projection, DLP display and so on.

8. User-defined modes: We offer abundant assignable modes function, there are 30 built-in user-defined modes,

and a lot of external user-assigned modes, and touch panel supported such as Crestron.

9.Image parameters (white balance/brightness/contrast/saturation) adjustment:

All the parameters are set as standard state when the goods leave the factory, users can adjust

it according to the actual need. For example, user can adjust the white balance of each output to

make the comprehensive white balance of TV wall/splicing wall reach a state as perfect as possible.

10. Background Logo display (customized requirement): available as a background logo display,

according to the demand of customer , we will store the segmentation images in the corresponding interfaces,

the background logo can be spliced into a complete image, each on-screen background logo can be activated

or deactivated and can be replaced freely as you need.
