1. Each pixel has two values, which are luminance and chrominance . 2. Thinning works because the eye better resolves brightness details than chrominance details. 3. RCA worked along different lines entirely, using the luminance-chrominance system. 4. TV cameras used in broadcasting usually generate luma number and two chrominance numbers. 5. RCA worked along different lines entirely, using a luminance-chrominance system. 6. The compromise can improve text appearance when luminance detail is more important than chrominance . 7. In effect, the remaining chrominance values represent the nearby values that are deleted. 8. The resulting subcarrier sidebands is also known as " chroma " or " chrominance ". 9. I and Q represent the chrominance information. 10. In the above, Y refers to luminance samples, and C to chrominance samples.
