Pixels are organized as interleaved luma and chroma planes. -Two lines of luma data are followed by one line of chroma data. - -The luma plane has one byte per pixel. The chroma plane contains -interleaved CbCr pixels subsampled by ½ in the horizontal and vertical -directions. Each CbCr pair belongs to four pixels. For example, -Cb\ :sub:`0`/Cr\ :sub:`0` belongs to Y'\ :sub:`00`, Y'\ :sub:`01`, -Y'\ :sub:`10`, Y'\ :sub:`11`. - -All line lengths are identical: if the Y lines include pad bytes so do -the CbCr lines. - -**Byte Order.** -Each cell is one byte. - - -.. flat-table:: - :header-rows: 0 - :stub-columns: 0 - - * - start + 0: - - Y'\ :sub:`00` - - Y'\ :sub:`01` - - Y'\ :sub:`02` - - Y'\ :sub:`03` - * - start + 4: - - Y'\ :sub:`10` - - Y'\ :sub:`11` - - Y'\ :sub:`12` - - Y'\ :sub:`13` - * - start + 8: - - Cb\ :sub:`00` - - Cr\ :sub:`00` - - Cb\ :sub:`01` - - Cr\ :sub:`01` - * - start + 16: - - Y'\ :sub:`20` - - Y'\ :sub:`21` - - Y'\ :sub:`22` - - Y'\ :sub:`23` - * - start + 20: - - Y'\ :sub:`30` - - Y'\ :sub:`31` - - Y'\ :sub:`32` - - Y'\ :sub:`33` - * - start + 24: - - Cb\ :sub:`10` - - Cr\ :sub:`10` - - Cb\ :sub:`11` - - Cr\ :sub:`11` - - -**Color Sample Location:** - - - -.. flat-table:: - :header-rows: 0 - :stub-columns: 0 - - * - - - 0 - - - - 1 - - 2 - - - - 3 - * - 0 - - Y - - - - Y - - Y - - - - Y - * - - - - - C - - - - - - C - - - * - 1 - - Y - - - - Y - - Y - - - - Y - * - - * - 2 - - Y - - - - Y - - Y - - - - Y - * - - - - - C - - - - - - C - - - * - 3 - - Y - - - - Y - - Y - - - - Y |
