    en.wikipedia.org/wiki/Candela_per_square_metre

    As a measure of light emitted per unit area, this unit is frequently used to specify the brightness of a display device. The sRGB spec for monitors targets 80 cd/m 2 . [ 3 ] Typically, monitors calibrated for SDR broadcast or studio color grading should have a brightness of 100 cd/m 2 . [ 4 ]

  9. Chroma subsampling - Wikipedia

    en.wikipedia.org/wiki/Chroma_subsampling

    The two chroma components are sampled at half the horizontal sample rate of luma: the horizontal chroma resolution is halved. This reduces the bandwidth of an uncompressed video signal by one-third, which means for 8 bit per component without alpha (24 bit per pixel) only 16 bits are enough, as in NV16.
