This is a planar format similar to the -4:2:2 planar format except with half as many chroma. The three -components are separated into three sub-images or planes. The Y plane is -first. The Y plane has one byte per pixel. The Cb plane immediately -follows the Y plane in memory. The Cb plane is ¼ the width of the Y -plane (and of the image). Each Cb belongs to 4 pixels all on the same -row. For example, Cb\ :sub:`0` belongs to Y'\ :sub:`00`, Y'\ :sub:`01`, -Y'\ :sub:`02` and Y'\ :sub:`03`. Following the Cb plane is the Cr plane, -just like the Cb plane. - -If the Y plane has pad bytes after each row, then the Cr and Cb planes -have ¼ as many pad bytes after their rows. In other words, four C x rows -(including padding) is exactly as long as one Y row (including padding). - -**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: - - Y'\ :sub:`20` - - Y'\ :sub:`21` - - Y'\ :sub:`22` - - Y'\ :sub:`23` - * - start + 12: - - Y'\ :sub:`30` - - Y'\ :sub:`31` - - Y'\ :sub:`32` - - Y'\ :sub:`33` - * - start + 16: - - Cb\ :sub:`00` - * - start + 17: - - Cb\ :sub:`10` - * - start + 18: - - Cb\ :sub:`20` - * - start + 19: - - Cb\ :sub:`30` - * - start + 20: - - Cr\ :sub:`00` - * - start + 21: - - Cr\ :sub:`10` - * - start + 22: - - Cr\ :sub:`20` - * - start + 23: - - Cr\ :sub:`30` - - -**Color Sample Location:** - - - -.. flat-table:: - :header-rows: 0 - :stub-columns: 0 - - * - - - 0 - - 1 - - - - 2 - - 3 - * - 0 - - Y - - Y - - C - - Y - - Y - * - 1 - - Y - - Y - - C - - Y - - Y - * - 2 - - Y - - Y - - C - - Y - - Y - * - 3 - - Y - - Y - - C - - Y - - Y |
