Control System

GBA and EVGC - Perfect colours
Despite the fact that we use only top LED diodes sorted by colour and brightness and produced by top world producers, the LEDbow videowalls are equipped with other features for perfect picture.

Global Brightness Adjustment (GBA) - allows the adjustment of global brightness of the whole panel in 16 brightness steps so that it is not a problem to watch the panel both at night and in bright sunshine, maintaining 2 displayed colour shades.

Enhanced Video Gamma Correction (ECCGC) - adjusts colour information so that it is displayed correctly, independent of the LED quality or global brightness of the panel. Before the actual display, it adjusts colours for every pixel through gamma and anti- gamma functions for clear borders between colour shades.

OVR - Stable picture under all conditions

Overscan Video Refreshing (OVR) To achieve a stable signal from any source (even from a TV source with the refresh rate of only 50 Hz and an unpleasantly blinking picture) the Overscan Video Refreshing (OVR) unit transfers input signals to a 450 Hz system, which provides a very stable and non-blinking picture.

ARS - Flexibility, modularity, easy service

Automatic Reconfiguration System (ARS) This system provides a possibility of any configuration of a videowall from long stripes to classic sizes 4:3 or 16:9. All videowall components are interchangeable without any special settings. That is how the HOT SWAP service is provided - simple replacement of a part without activation and configuration. This also allows the construction of hybrid walls of more parts with various raster points.

ABS - Blending pictures without special equipment

Alpha Blending System (ABS) processes the information from an alpha channel, a part of all data. The information in 256 levels determines the blending rate of individual video system pixels and a picture from control PC. Inserting subtitles or result lists directly into the video signal (picture tagging), is very simple with this system. It makes it easy, for example, to display your logo on the panel, as it is possible in TV broadcast.

RCC and ICC - Comfortable videowall management from anywhere

Remote Control Console (RCC). The console is connected to a master computer through wireless connection operable in distances up to hundreds of meters. Therefore it is possible to manage the panel through a light and portable device, even right in front of the LED panel.
Internet Control Capability (ICC) . allows management of a videowall through the Internet, from your office or home.

AGC, VPF and EVFS - Other improvements of a perfect picture through a system of digital filters

Automatic Gain Control (AGC) is a system synchronizing input signals of different intensity, for example signals from different sources.
Video PreFiltring (VPF) filters noise from the signal and provides aliasing correction.
Enhanced Video Filtering System (EVFS) comprises of three filters:
  • Fast Motion filter is suitable especially for high speed movement,
  • MPEG filter corrects the signal from DVD or other source of MPEG2 or MPEG4 signals
  • Infinity Horizon filter corrects signals with lots of noise
