Introduction
The S902 is a 4x2 UHD Quad-View processor that allows users to display up to four 4k/60 sources simultaneously on one or two UHD displays. This device offers a highly flexible and cost-effective solution for routing up to four 4k/60 sources to two separate displays simultaneously. Users can choose from 12 default multi-view layout presets and 20 custom Profile Presets to customize their display mode.
Featuring 4 HDMI 2.0 inputs and 2 HDMI 2.0 outputs, the S902 supports CEA video standard timings up to 4096*2160 @60Hz with 4:4:4 chroma sampling. Each output port can accommodate up to 4 windows, with each window capable of selecting an input source from any input port. Users have the option to assign the same input source to multiple windows and can adjust input selection, image positioning, resizing, cropping, and color settings for each window.
Users can prioritize display windows when they overlap and select one or multiple windows with the same configuration for any output port. The device offers 16 transition modes, including high speed seamless switching, Fade-in, Fade-out, Dissolve, and Wipe, with selectable duration for transitions. It integrates HDMI embedded audio, RCA SPDIF digital audio, and analog 3.5mm R/L audio jack R/L, allowing users to assign audio from input ports to each audio output port as needed.

DE-INTERLACING (Pictures from Genesis Microchip)
- This function is for user to select different de-interlacing method in video editing.
- The major application is for interlaced signal source such as 2160i, 1080i, 480i... which user can only see odd frame or even frame in one time. Properly conversion of interlaced signal into progressive signal will get the best video quality especially in motion picture.
- When de-interlacing is turned off, it will implement double scaling to fulfil complete video frame.
- Below are some examples:

Usually, the default is to turn on all functions under DE-INTERLACING. In some Lab, user can turn on/off some functions to verify the type of the video source (such as the video is 3:2 or 2:2 Pulldown) for further video editing. It can also be used in the school for video teaching class to under different video functions.
NOISE REDUCTION
- The video content may come from different signal sources, such as PC, video camera, DVD, broadcasting, de-compressed video, de-compressed image... Each signal source may preserve different types of noise.
