WebThe conversion between RGB and YUV for HDTV (BT.709). YC b C r is a scaled and offset version of the YUV color space. Y has an 8-bit range from 16 to 235. Cb and Cr have a range of 16-240. YC b C r is used for JPEG compression. If the RGB data has a range of 0-255 (black-white), as is commonly found in PCs, the following equations should be ... WebYou could output the YUV values directly into a full-sized YUV image (with the Y, u, and v values of a single pixel stored together in the RGB channels of the output) and then further compress this into the disparate memory layout you need, either on the CPU or in another pixel shader that just decides what channels to read from the Yuv image ... adi sector
