color of paint, The RGB mode is often used on the monitor, which is different from the pal or NTSC video standard. Conversion between YUV and yiq The conversion formula between YUV, yiq, and RGB is as follows: Y = 0.299r + 0.587G + 0.114b U = B ━ y V = r y I = 0.877 (R-Y) cos33 platinum 0.492 (B-Y) sin33 Q = 0.877 (R-Y) sin33 + 0.492 (B-Y) cos33 RGB is composed of three primary colors: R, G, and B. Similarly, YUV is composed of three elements: Y, U,

horizontal axis is the time, and the ordinate is MOS. A rectangle outside the gray line represents a 95% confidence interval for that place. The following two images show the results of the encoder comparison. The horizontal axis is the SSCQE fraction of an encoder, and the ordinate is the sscqe fraction of another encoder. Figure 7 is a comparison of streaming media content, with letters corresponding to the letters in the sequence in table 1. The
