Instead, luminance and chrominance samples are grouped into 4s so that each group is packed into an integer number of bytes: YYYY =3D UVUV =3D 4 * 10 bits =3D 40 bits =3D 5 bytes The '20' and '30' suffix refers to the optimum effective bits per pixel which is achieved when the total number of luminance samples is a multiple of 4.
