14
15 <para>M420 is a YUV format with &frac12; horizontal and vertical chroma
16 subsampling (YUV 4:2:0). Pixels are organized as interleaved luma and
17 chroma planes. Two lines of luma data are followed by one line of chroma
18 data.</para>
19 <para>The luma plane has one byte per pixel. The chroma plane contains
20 interleaved CbCr pixels subsampled by &frac12; in the horizontal and
21 vertical directions. Each CbCr pair belongs to four pixels. For example,
22Cb<subscript>0</subscript>/Cr<subscript>0</subscript> belongs to
23Y'<subscript>00</subscript>, Y'<subscript>01</subscript>,
24Y'<subscript>10</subscript>, Y'<subscript>11</subscript>.</para>
25
26 <para>All line lengths are identical: if the Y lines include pad bytes
27 so do the CbCr lines.</para>
