The IP00C790 is the industries first, exclusive LSI for 4K warping and edge blending.
It can handle a native 4K image up to 4096 x 2160, 60fps.
This chip is capable of single color processing of either: R, G or B. A full color 4K implementation requires three C790 chips.
However, the 4K implementation based on the C790 is easier to design.
This is because of the embedded frame memory and direct connection, through a proprietary interface, between the C790 and the C734 a front-end scaler.
Also, the C790 features image quality control and correction such as per pixel edge-blending and uniformity correction etc., that is required to achieve higher image quality.
