about

nx_vcodec_color.nx -- sovereign COLOR foundation for the s-class video codec (operator 2026-06-23: "s class exceed no matter the investment, from the hardware rung up, no third-party"). The luma-128 codec is grayscale; s-class is COLOR. Color starts here: integer BT.601 RGB<->YCbCr (no float, built straight on the ALU/integer hardware rung). The codec encodes the Y/Cb/Cr planes; the camera gives RGB, the display wants RGB, so this is the gateway both ways. Pure integer, sovereign, our own. license_tier: ORIGINAL
