Introduction
G901 is multiple purpose video processor for seamless switcher, scaling up and down, image
flip/rotation/cropping, video wall, PIP/POP, 3D format conversion and multi-viewer functions. The input
supports various input sources and input timings. It is an ideal front end processor for big display system
required 4k/60 input and output.
5 input ports (3x HDMI, 2x DP) and 1x HDMI outputs are designed in G901. Input supports up to
4096*2160 @60Hz, 7680*2160 @30Hz in HDMI input and 7680*4320 @30Hz in DisplayPort input with 4:4:4
chroma sampling. No VESA standard input timings are also supported up to 600 MHz.
Programmable output supports up to 4096*2267 @60Hz or 7680*1234 @60Hz output resolution. The
range is from 800-7680 (with 8 pixel/step under 230Mhz, 16 pixel/step above 230MHz) in horizontal and 720-
3840 (with 1 pixel/step) in vertical. The maximum resolution is limited to 600MHz. Output refresh rate can be
selected from 24/30/50/60/100/120Hz.
It is integrated with 10-bit high end processor, motion adaptive de-interlace, low angle smooth
algorithm, 3:2/2:2 pull-down cadence. Programmable EDID enables optimized input timing to get the best
video quality.
It is integrated with color adjustment in Brightness, Contrast, Hue, Saturation, Sharpness, color
temperature and discrete RGB gain adjustment. Automatically detect and process HDR BT. 2020 input signal
and output with full color 4:4:4 RGB SDR signal. User can select deep color mode with true 10-bit color output
to get smooth gradient color.
Video wall function in G901 can crop specific location & resolution in source image for programmable
output. Overlap function allows user to change image position, aspect ratio and cropping area up to +_1800
pixels in each edge. User can adjust aspect ratio and image position freely. Image 90/180/270 degrees flip
and rotation are also available. It is an ideal front end solution for LED and big display system.
PIP (picture in picture) and POP (side by side or top/bottom) are standard functions in G901. 3 split
view and 4 split view MultiViewer function is embedded. PIP image size can be from 320*180 up to
1920x1200. It can be located at any location across entire display. Both main and sub-windows can be flipped
and rotated at 90/180/270 degrees. The cropping range and position in both main and sub-window are
adjustable. Maximum input sources can be displayed in one G901 is four. The color adjustment function in
sub-window is also integrated to allow more application flexibility.
G901 can execute 3D format conversion function. It can convert HDMI 1.4 standard 3D format (side by
side, top/bottom, frame sequential, Line interleaved, frame packed, discrete dual camera…) into side by side,
top/bottom and frame sequential 3D output format. It can also decode 3D signal into discrete RH or LH for
passive display. Some medical device can only output Line interleaved 3D format and can’t be supported by
many 3D display devices. User can use G901 to convert Line interleaved 3D format into other 3D format so
that it can be displayed in all 3D display devices.
User can use IR controller, USB, Web Gui and Ethernet for system operation and setup. User can save
up to 10 customized settings in G901 and recall through remote controller, USB or Ethernet connection. It is
designed to work in 7/24 working environment and provides easy configuration, low entry barrier, cost
effective, reliable and flexible solution.
